Q) What technologies you are using in your project.

A) I am using Java as core technology to maintain the front view part I am using JSP, HTML, CSS and JS. To handle the server request I am using servlet and to store data or maintain the back end records using MYSQL database.

Blow is the brief definition about the technologies using in the project

HTML

I am using HTML to create front end GUI functionality like input fields, Heading of the all pages, page tittle, Buttons ETC. Html provides Tags for every part of page design. For example I am creating footer of the page. So there is footer page is available similarly header tag for header part and the body tag for body part of the page. We can add images as well using img tag.

Java Script

Js is a programming language mostly use to set the validation at client side. As the Java script team is updating there technologies these days lots of frame work is available like Node js, view Js, react js. Which supports client site as well as server site. Js is the one the big programming which support all the things. It is open source so it’s used widely. We are using js in our project to create front end validation. We are using js to set proper validation for the input fields like DOB, and password Fields.

CSS 

We are using CSS for designing purpose. Its helps to create more attractive HTML pages. CSS and its updated versions like css3 and css5 supports animation and some advance design things. Which makes our application more attractive. We are using CSS3 for basic use like to manage divisions passions. To add some color in heading and footer page.

Servlet

I am using Servlet as server side programming language. Which is responsible to  handle the request which is coming form the view part. As we are using MVC architecture so the controller part would be handle by only servlet by the post and Get methods.

Server

I am using Tomcat server which provide by the apache corporation and its open source server. Which is help to deploy and run our application on the localhost server. It will generate a local URL with local host and port number(xxxx) with the project name. It will help to compile and run our JSP and servlet code as well.

JAVA

Java is the core programming language for this project. To perform bean operation, logical operation we are using the java. In the project we using the object model which is follow by the java. Is is an open source programming and provide all the support at client side as well as server side. We are using java code and syntax in servlet. As well as using JSP also for the logic operation like IF else or conditional statements.

MYSQL

It is an relational database management system. In this project we are using mysql to store the data of employee. There is separate table to divide the data and each table is relate to other. Unique and foreign keys are responsible for the relations between the tables. 

To operate the database we are using MYSQL workbench which is quite simple and easy to understand. MYSQL server is running on the port number 3306 with the username “root” and password “root”.

Q) What is MVC and why you are using MVC in your project.

While building your college project or your first java project its really Important to manage all the source file manage in a proper way. So we are using MVC with every java project to manage the View part, Controller part as well as model part. Model(Model package) in every java project contains all the database related source code. Like All the transactions which is user to get data from database and insert data into the database. JDBC related code. Build Java project with maven is really simple and good practice to mange your source code as well as for the industry standards. MVC is not a tool its a way of programming.

Q) What is Maven?

Maven is tool which is use to manage the Jar files of your project in a easy or proper way. And It happen only some min line of code. You just need to add 3-4 line code in the Pom.XML file. When we create a project with maven tool. It will create a Pom.xml automatic. This is the file which contains all the dependency(code of the Jar files). That we need to add inside the <dependencies></dependencies> tag. And don’t worry we do not need to create that 4 lines. This code easily available on the internet you just need to Google about it.

Q) Where you did database connectivity in your project?

We are using Model package to maintain the data base transactions and write common code to connect database in properties file.

 Q) Where is the Code of Controller, Model and view in the project?

Please follow the below screenshot to get the Idea where is the code about the controller, Model and View.

Here Controller means Servlet, View means JSP and Model mean Database transaction.
