1. Data Structures and Algorithms

1Introduction

A data structure is a named location that can be used to store and organize data. An algorithm is a collection of steps to solve a particular problem. Learning data structures and algorithms allow us to write efficient and optimized computer programs. Data structures provide a means to manage large amounts of data efficiently for uses such as large databases and internet indexing services. Usually, efficient data structures are key to designing efficient algorithms.
In the first week of this course, you will learn:

  • Stack memory vs heap memory in Java
  • Physical vs logical data structure
  • Abstract data type and data structure
  • Complexity analysis
    • Asymptotic analysis, comparison of functions, recurrence relations
    • Time complexity
    • Space complexity
    • Master theorem
    • Amortized analysis
    • Iteration vs recursion
  • Recursion - Factorial, Fibonacci, finding nCr, tower of Hanoi problem.

2Arrays, Strings, and Lists

Arrays are used to store multiple values in a single variable, instead of declaring separate variables for each value. A string is a sequence of characters like - "hello". In this string the sequence of characters is 'h', 'e', 'l', 'l', and 'o'. Unlike other programming languages, strings in Java are not primitive types like int and char. Instead, all strings are objects of a predefined class named string. A LinkedList is a part of the collection framework present in Java. util package. This class is an implementation of the LinkedList data structure which is a linear data structure where the elements are not stored in contiguous locations and every element is a separate object with a data part and address part.

In this session, we will learn about:

  • Arrays
    • Static arrays
    • Dynamic arrays
    • 2D arrays, row-major and column-major mapping, matrices
  • Strings
  • LinkedList
    • Singly LinkedList and its operations
    • Doubly LinkedList and its operations
    • Circular LinkedList and its operation


3Stacks and Queues

The stack is a linear data structure that is used to store the collection of objects. It is based on Last-In-First-Out (LIFO). Java collection framework provides many interfaces and classes to store the collection of objects. One of them is the stack class that provides different operations such as push, pop, search, etc. The queue is used to represent an ordered list of elements. It follows the FIFO or First In First Out procedure to insert and remove elements. The queue also supports methods of collection interface.

In this session, we will be discussing-
  • Stacks
    • Implementations- using arrays, using linked lists
    • Operation
    • Applications
  • Queues
    • Implementations- using arrays, using a LinkedList, using two stack
    • Circular queues
    • Priority queues


4Trees

A tree is a non-linear data structure where data objects are organized in terms of hierarchical relationships. Java provides two in-built classes, TreeSet and TreeMap, in Java Collection Framework that cater to the needs of the programmer to describe data elements in the aforesaid form. There are many different types of tree structures available and we’ll be discussing them one by one

  • Trees.
    • Binary trees, their representations.
    • Pre-order, In-order, post-order traversals
    • Binary search trees
    • AVL trees


5 Heaps and Tries

Heap and Trie are a special case of trees. A Heap is a special tree-based data structure in which the tree is a complete binary tree. Trie is an efficient information retrieval data structure. Using Trie, search complexities can be brought to the optimal limit. In the session, we will try to solve the longest word in the dictionary problem using Tries.

  • Heaps
    • Min Heap
    • Max Heap
    • Find K largest (or smallest) elements in the array.

  • Trie


6Graphs & Algorithms

A graph is a data structure that consists of- 1. A finite set of vertices also called as nodes and 2. A finite set of ordered pairs of the form (u, v) called as edges. Algorithms in Java are static methods that can be used to perform various operations on collections. Since algorithms can be used on various collections, these are also known as generic algorithms. We will be discussing different types of algorithms like-
  • Graphs
    • Types of graphs
    • Breadth-first search, depth-first search
    • Topological sort
    • Shortest path problem
  • Algorithms
    • Dijkstra's algorithm
    • Bellman–Ford algorithm
      • Minimum spanning tree problem
    • Prim's algorithm
    • Kruskal's algorithm


7Sorting

Sorting generally means to put data in a certain order. The order can either be alphabetically sorted or numerically sorted. There are many types of sorting techniques available in Java. We will be discussing each of them in this session.
  • Sorting- 
    • Types of sorting techniques
    • Bubble sort
    • Insertion sort
    • Selection sort
    • Quick sort
    • Merge sort
    • Heap sort
    • Count sort
    • Bucket sort
    • Radix sort
    • Shell sort


8Searching and Hashing

Searching is probably one of the most common actions performed in a regular business application. This involves fetching data stored in data structures like arrays, list, and maps. More often than not, this search operation determines the responsiveness of the application for the end-user. Hashing is the process of converting a given key into another value. A hash function is used to generate the new value according to a mathematical algorithm. The result of a hash function is known as a hash value or simply, a hash.

Hashing is primarily used for authentication. Chaining is the practice of calling different methods in a single line instead of calling different methods with the same object reference separately. Under this procedure, we have to write the object reference once and then call the methods by separating them with a (dot.). Similar to chaining, open addressing is a method for handling collisions. In open addressing, all elements are stored in the hash table itself. So at any point, the size of the table must be greater than or equal to the total number of keys.

During this week we will be discussing about the following:

  • Searching
    • Linear search
    • Binary search
  • Hashing
    • Hash function
    • Collision handling
  • Chaining
  • Open addressing
    • Linear probing, primary clustering
    • Quadratic probing, secondary clustering
  • Double hashing

9 Greedy Algorithms

A greedy algorithm is a simple, intuitive algorithm that is used in optimization problems. The algorithm makes the optimal choice at each step as it attempts to find the overall optimal way to solve the entire problem. Greedy algorithms are quite successful in some problems, such as Huffman encoding which is used to compress data, or Dijkstra's algorithm, which is used to find the shortest path through a graph. Such algorithms are called greedy because while the optimal solution to each smaller instance will provide an immediate output, the algorithm doesn't consider the larger problem as a whole.

The topics discussed in this session will be-

  • The strategy of greedy algorithms
  • Elements of greedy algorithms
  • Advantages of greedy algorithms
  • Disadvantages of greedy algorithms
  • Applications of greedy algorithms
  • Knapsack problem
  • Job sequencing with deadlines
  • Huffman coding

10Divide and Conquer

The divide and conquer approach is pretty straightforward, the problem in hand is divided into smaller subproblems and then each problem is solved independently. As we keep dividing the subproblems into even smaller problems, we eventually reach a stage where no more division is possible. These "atomic" smallest possible problems are then solved. The solution of all "atomic" problem sets are finally merged in order to obtain the solution of an original problem.


In the session this week ,we will discuss:


  • The strategy of divide and conquer techniques
  • Advantages of divide and conquer techniques
  • Disadvantages of divide and conquer techniques
  • The master theorem of divide and conquer techniques
  • Applications of divide and conquer techniques
  • Find the median of two sorted arrays


11Backtracking

acktracking is an algorithmic-technique for solving problems recursively by trying to build a solution incrementally, one piece at a time, removing those solutions that fail to satisfy the constraints of the problem at any point of time. We’ll discuss about two methods used to backtrack.
  • Backtracking- 
    • Brute force approach
    • N queens problem
  • After backtracking we will be studying how Java 8 collections framework is implemented. We will be covering the following,
    • Set
    • List
    • Queue
    • PriorityQueue
    • Map
    • HashSet
    • TreeSet
    • ArrayList
    • LinkedList
    • Vector
    • Dictionary
    • Stack


12Dynamic Programming

Dynamic Programming is also an algorithmic technique for solving the optimization of problems. It is done by breaking the problem down into simpler subproblems and utilizing the fact that the optimal solution to the overall problem depends upon the optimal solution to its subproblems.

During this session, we will be covering the following:

  • Dynamic programming- 
    • The strategy of dynamic programming
    • Properties of dynamic programming
    • Approaches of dynamic programming
    • 0/1 knapsack
    • Travelling salesman problem
    • Floyd Warshall
  • In the end, we will conclude and summarize the course by having a brief discussion on Greedy vs Divide & Conquer vs Dynamic Programming.

3. Java Web Applications Development

1Introduction

Java is probably one of the most commonly used web development software out there in the market. And it is among the top for good reason. Java is very backward compatible. This means that when a new version is released, in all likelihood, your existing code will work. That's a huge deal to large organizations that have multiple projects and millions of lines of code. Java standardizes many vital aspects like, how things must be named, and even makes recommendations on code formatting. This means that all java code looks very similar, which makes the code easy to read. So when you swap people on projects, the learning curve isn't steep. The developer tools are excellent, especially when compared to most other languages. The software also has an enormous ecosystem that has evolved over many years. When starting a project, it's great knowing that most of your grunt work can be handled easily. With the dilemma of WHY JAVA? Aside, we’ll focus on what we will be discussing in the first week of the course. In this week, we’ll be talking about-
  • Java SE, ME, and EE
  • Introduction to Java EE
  • What is a web application?
  • The client-server architecture
  • Setting up the Java development environment
  • Why use a server?
  • Installing MySQL Tomcat
  • Using Maven
  • Add and update project dependencies within a Maven POM file
  • Creating a Software Design Document.


2JSP and Servlets

Both JSP and Servlets are a part of the JAVA ecosystem. Both are sufficiently different. The servlet is a Java class which extends the capabilities of servers that host applications and is accessed by means of a request-response model.  Servlets are mainly used to extend the applications hosted by web servers. A JSP is a text document which contains two types of text: static data and dynamic data. The static data can be expressed in any text-based format (like HTML, XML, SVG and WML). This week we will cover-

  • The role of a Servlet within a Java Application Server
  • Reading an HTTP request and generating a response
  • Get vs Post
  • Introduction to Model View Controller in a Java web application
  • Java Server Pages- using directives, handling errors
  • Jakarta Standard Tag Library (JSTL)
  • Java Beans
  • Session management and tracking
  • Event listeners, Event handlers
  • Filters
  • Multithreading in Java

3Connecting with MySQL

MySQL is one among the most widely used open source database management systems. One of the reasons MySQL is the world's most popular open source database is that it provides comprehensive support for every application development. Within the database, support can be found for stored procedures, triggers, functions, views, cursors, ANSI-standard SQL, and more. With a plethora of functionalities it is vital that you know how to connect JAVA to MySQL. In this week we will discuss

  • The Java Naming and Directory Interface (JNDI) 
  • JDBC (Java Database Connectivity)
  • Connect with the MySQL database
  • Mappings between Java objects and SQL tables
  • Connecting an application with a data store using these mappings

  • Create a database and table using Java
  • Create an entry in the database
  • Update the entry in the database
  • Read from the database
  • Delete from the database


4Spring

Spring is a Framework. A framework is essentially a bunch of boilerplate code that is written for you to simplify a lot of the basic setup you would need to do to get a project started. Once your project is started, frameworks contain lots of code that makes doing common tasks for your project easier. Frameworks are designed with certain assumptions about what type of projects will be built with them and what kind of tasks their users will perform. Now on to Spring. Spring is a type of framework that contains a lot of tools for a lot of different types of projects. Spring is mostly used in enterprise-level projects that scale in a big way. This week, we will be setting you in pace with frameworks and springs. The topics covered will be
  • What is a framework?
  • What is the need for a framework?
  • Identify the role of Spring as a Servlet application tool
  • Architecture and project setup
  • Spring configuration and Dependency injection
  • Spring scopes
  • Autowiring
  • Spring Bean, Bean lifecycle

    • Creating Controllers in Spring MVC
    • Populating the data model for a given view using the Controller
    • Using Thymeleaf in Spring MVC views
    • Springform
  • Database connectivity


5Hibernate

Hibernate is an ORM framework for java applications, it is a way of working with data in the database as objects increasing the speed of development. But what is an ORM? ORM stands for Object-Relational Mapping (ORM). It is a programming technique that is used to convert data between relational databases and object-oriented programming languages such as Java and C#. Since Hibernate is an ORM tool, it simplifies data creation, data manipulation, and data access. It is a programming technique that maps the object to the data stored in the database. This week, we will cover-

  • How to use ORM to reduce development time and programmer error
  • Understanding key concepts in ORM- Persistence Context and Entity Manager
  • Hibernate
  • Spring Data Java Persistence API (JPA)
  • The JPQL (Java Persistence Query Language)- Writing and executing object queries in Java
  • Isolating Entity scope through the use of annotations and Data Transfer Objects
  • Propagating retrievals and persistence using Lazy Loading and Cascading
  • Controlling the execution of queries through Transactions
  • Customizing Spring Data Source construction and injection
  • SQL vs Hibernate, combining both in the same project


6 Spring Boot

Spring Boot is an open-source framework used to create microservices. It is easy to create stand-alone and production-ready Spring applications using Spring Boot. Spring Boot offers a fast way to build applications. It looks at your classpath, and at the beans you have configured, makes reasonable assumptions about what you are missing, and adds those items.  Spring Boot contains comprehensive infrastructure support for developing a microservice and enables you to develop enterprise-ready applications that you can “just run”. In this week we will cover-
  • What is the Spring Boot?
  • Setting up and configuring a working Spring Boot Environment for web development
  • Creating a Spring Boot Application using annotations and factory methods
  • Connecting to the Database, JPA
  • Identifying Spring registered components in Java applications based on Spring annotations
  • Annotating code to register custom components
  • Introduction to Microservices
  • Identifying and customizing essential properties for the Spring Server


7Security

Web security is vital to keep hackers and cyber-thieves from accessing sensitive data and information. Without a proactive security strategy, businesses risk the spread and escalation of malware, attacks on websites, networks, and other IT infrastructures. As technology changes, it becomes increasingly challenging for businesses of all types to keep their personal and customer’s information on the web secure. We will specifically talk about the OAuth security library for JAVA. The topics we will be covering are-
  • The need for security in modern day web applications
  • Authentication vs authorization
  • OAuth 2.0
  • Authentication- Spring Security
  • Basic Authentication practices to secure an API
  • Best practices for authorization and authentication
  • Modern authorization and authentication technologies


8 Web Services

There is no specific way to answer the question- “What is a web service?”. Essentially, web services include any software, application, or cloud technology that provides standardized web protocols (HTTP or HTTPS) to interoperate, communicate, and exchange data messaging through the internet. In the course we will talk about - SOAP and REST.  This will include
  • Web service and its advantages
  • How web services communicate
  • Web services vs APIs vs Microservices
  • SOAP (Simple Object Access Protocol)
  • Consuming a SOAP-based web service
  • The REST architectural style
  • RESTful Web Services and JAXRS
  • Using Postman to create and test RESTful APIs
  • Consuming a REST API
  • Creating a Spring Boot, Hibernate, MySQL RESTful API


9Deployment

Software deployment refers to the process of making the application work on a target device, whether it is a test server, production environment or a user's computer or mobile device. A lot can go wrong during software deployment. 
Understanding the different ways a manual deployment can fail and how automation can combat these failures will help reduce the risk of them occurring. Read on to learn about the top five manual deployment failures and how they could have been avoided with automation. Heroku is a very common software used for automation of deployment. In this week we will cover-
  • Deployment
  • Deploying spring boot applications
  • Implementing CORS
  • Hosting on Heroku

4. Design Patterns for Building Scalable Applications

1 Introduction to Scalable Systems

Scalability is generally a property of a system to handle more work by adding more resources to the system. This is vital for a website or an app as it also needs to improve and expand as the business or service it caters to, expands. The topics we will be covering in specific are-
  • Understanding scalable systems
  • Understanding scalable systems with respect to consistency
  • Understanding scalable systems with respect to availability 
  • Understanding scalable systems with respect to scalability

2 Distributed Systems

In a distributed system, the components that are located on different networked computers can communicate and coordinate their actions by passing messages to one another. The components interact with one another in order to achieve a common goal. The topics we will be covering will be-
  • Consistency in distributed systems
  • Laws of scalability
  • Performance vs. scalability

3Building Blocks of Scalable Architecture

Building blocks are the commonly used infrastructure, software, tools, frameworks and services that can be used to build a scalable system. This week, we will be talking about the building blocks of scalable architecture. Here, we will be discussing the commonly used infrastructure, software, tools, frameworks and services that can be used to build a scalable system. The topics discussed are-
  • Concepts required for designing a scalable architecture.
  • Caches
  • NoSQL database
  • Messaging queues
  • Load balancers

4 Introduction to Design Patterns

A design pattern provides a general reusable solution for the common problems occurring in software design. The patterns typically show relationships and interactions between classes or objects. That means a design pattern represents an idea, not a particular implementation. In the following 5 sessions, we will be discussing much more in depth on topics of Design Patterns. In this session, we will be discussing 
  • Introduction to design pattern
  • How design patterns help in solving problems along with some vintage examples
  • Simple design patterns concepts

5More on Design Patterns

Design patterns is a vast subject with a multitude of topics to be covered. Here, we will be talking about

Load balancer: The load balancer mechanism is a runtime agent with logic fundamentally based on the premise of employing horizontal scaling to balance a workload across two or more IT resources to increase performance and capacity beyond what a single IT resource can provide. Beyond simple division of labor algorithms, load balancers can perform a range of specialized runtime workload distribution functions that include

  • Scatter and gather: The scatter and gather pattern is a tree pattern with a root that distributes requests and leaves that process those requests. Here, the requests are simultaneously farmed out to all of the replicas in the system. Each replica does a small amount of processing and then returns a fraction of the result to the root. The root server then combines the various partial results together to form a single complete response to the request and then sends this request back out to the client.
  • Result cache: A result cache is an area of memory, either in the Shared Global Area (SGA) or client application memory, that stores the results of a database query or query block for reuse. The cached rows are shared across SQL statements and sessions unless they become stale.
  • Shared space: In this pattern, all workers monitor information from the shared space and contribute partial knowledge back to the blackboard. The information is continuously enriched until a solution is reached.
  • Pipe and filter: Here, all the workers are connected by pipes through which data flows. This pattern is also known as “Data Flow Programming”
  • Map Reduce: The model is used to target batch jobs where disk I/O is the major bottleneck. It uses a distributed file system so that disk I/O can be done in parallel. This pattern is used in many of Google's internal applications, as well as implemented in open source Hadoop parallel processing framework. I also find this pattern can be used in many many application design scenarios
  • Bulk Synchronous parallel: This model is based on lock-step execution across all workers. It is coordinated by a master. Each worker repeats the following steps until the exit condition is reached, when there are no more active workers.
    • Each worker read data from input queue
    • Each worker perform local processing based on the read data
    • Each worker push local result along its direct connection
  • Execution Orchestrator: This model is based on an intelligent scheduler / orchestrator to schedule ready-to-run tasks (based on a dependency graph) across clusters of workers.

6 Design Patterns | SN Architecture, Database Sharding & More

We delve deeper into design patterns. Here, we will be talking about
  • Shared-nothing architecture: A shared-nothing architecture (SN) is a distributed-computing architecture in which each update request is satisfied by a single node. The intent is to eliminate contention among nodes. Nodes do not share  memory or storage. One alternative architecture is shared everything, in which requests are satisfied by arbitrary combinations of nodes. This may introduce contention, as multiple nodes may seek to update the same data at the same time.
  • Database Sharding: A shard is a data store in its own right (it can contain the data for many entities of different types), running on a server acting as a storage node. You can scale the system out by adding further shards running on additional storage nodes. The biggest advantage of this method is that you can scale the system out by adding further shards running on additional storage nodes. A system can use off-the-shelf hardware rather than specialized and expensive computers for each storage node. You can reduce contention and improve performance by balancing the workload across shards. In the cloud, shards can be located physically close to the users that'll access the data.
  • Master-Slave Database: Master-slave replication enables data from one database server (the master) to be replicated to one or more other database servers (the slaves). The master logs the updates, which then ripple through to the slaves. The slave outputs a message stating that it has received the update successfully, thus allowing the sending of subsequent updates.
  • Optimistic locking: Optimistic locking is a way to manage concurrency in multi-user scenarios. It is used to avoid situations when one user overrides changes made by another user without even looking at them. Locking - optimistic locking in particular - is a way to do that.
  • Eventual consistency: Eventual consistency is a consistency model used in distributed computing to achieve high availability that informally guarantees that, if no new updates are made to a given data item, eventually all accesses to that item will return the last updated value.
  • Pooling and multiplexing: Pooling and Multiplexing is a software creational design pattern that uses a set of initialized objects kept ready to use – a "pool" – rather than allocating and destroying them on demand. A client of the pool will request an object from the pool and perform operations on the returned object. 

7 Design Patterns | Optimizing Data Flow & Storage

Moving from types of Design Patterns, in this session, the emphasis will be on methods and procedures used to optimize data flow and storage.
In this session we discuss:
  • Data distribution
  • Usage of compression before sending data over a network
  • Data archival
  • Intelligent load distribution and
  • Graceful service degradation

8 Design Patterns | More on Data Flow & Optimization

In this session we continue our dialogue on methods to optimize data flow and storage.  Topics include:
  • Autonomy
  • Failure tolerant collocation
  • Caching
  • Remoting
  • Queuing
  • Batch processing
  • Relaxing data constraint

9 Design Patterns | Sub & Saga Pattern

This is the sixth session of Design Pattern. Here, we will be talking about

    • The pub-sub pattern-  The Publisher/Subscriber pattern, or “PubSub” for short, is a pattern that allows us to create modules that can communicate with each other without depending directly on each other. It’s a great pattern for decoupling our application and is quite common in JavaScript.
    • Saga pattern- Saga pattern is a design pattern to handle system failures in long lived transaction by dividing the long lived transaction into a set of independent sub-transactions with compensating sub-transactions.

    10 Case Study of a Scaling a Relational Database
