Solution :-

MySQL is a relational database management system (RDBMS) that uses Structured Query Language (SQL) to manage data. It is a widely used system with a large number of features that make it well suited for developing a CRUD application.

JDBC is a Java API that provides a standard way to access databases. It includes a set of classes and interfaces that can be used to connect to a database, execute SQL statements, and retrieve results.

To develop a CRUD application using MySQL and JDBC, you will need to install the MySQL server and JDBC driver on your computer. You will also need to create a database and table to store your data.

Once you have everything installed and set up, you can begin coding your application. The first thing you will need to do is write code to establish a connection to your database. You will need to provide the database name, username, and password. Once you have a connection, you can execute SQL statements.

To create a record, you will need to use the INSERT statement. This statement requires you to specify the columns and values for the new record. For example, to insert a new user into a table, you would use the following SQL statement:

INSERT INTO users (username, password, first_name, last_name)

VALUES ('jsmith', '123456', 'John', 'Smith');

To read data from a database, you will use the SELECT statement. This statement allows you to specify the columns that you want to retrieve, as well as any conditions that must be met. For example, the following SQL statement would retrieve all users from the database:

SELECT * FROM users;

To update an existing record, you will use the UPDATE statement. This statement requires you to specify the column and value that you want to update, as well as the id of the record that you want to update. For example, the following SQL statement would update the password for the user with id 1:

UPDATE users

SET password = '654321'

WHERE id = 1;

Finally, to delete a record, you will use the DELETE statement. This statement requires you to specify the id of the record that you want to delete. For example, the following SQL statement would delete the user with id 1:

DELETE FROM users

WHERE id = 1;

Once you have written the code to perform the CRUD operations, you can test your application by inserting, updating, and deleting records. You can also use the SELECT statement to retrieve data from the database and verify that the changes you made were successful.

In conclusion, MySQL and JDBC can be used to develop a CRUD application. By following the steps outlined in this article, you can easily create a basic CRUD application.

Explanation:

A relational database may be managed using the MySQL database management system. When spelled out, the abbreviation MySQL refers to the language known as My Structured Query Language (MSQL for short) (RDBMS). It is a fantastic option for the construction of a CRUD application since it is used by so many people and has such a comprehensive feature set. CRUD stands for "create, read, update, and delete."

When you make use of the Java Database Connectivity Application Programming Interface (JDBC), gaining access to databases is as easy as pie (API). It comes pre-installed with a wide number of classes and interfaces that may be used for the purposes of obtaining data, communicating with databases, and performing SQL queries. These capabilities are all included in the package.

Before commencing work on a CRUD application, you will first need to confirm that the MySQL server and the JDBC driver are correctly installed on your computer. Only after this step can you go on to the next step of the process. In addition to this, in order to correctly organize the information that you have collected, you will need to set up a database in addition to a table. This is required in order to properly organize the information.

After you have completed all that has to be done to develop your application, you will finally be ready to start writing the code for it. Creating some code on your own will be the first step in connecting to your database; however, you will need to do this before you can proceed. The hostname, the username, and the password are the three pieces of authentication information that you are required to enter into the database. If you have successfully established communication with the server, you are free to transmit SQL commands at this time.

Because there is no alternative method for producing new records, the INSERT command is the sole one that can be made because it is the only one that is accessible. This statement has to be revised in order to contain both the column names and the values that correspond to each column in the new record. Otherwise, you won't be able to use the new record. If you wanted to add a new user to a database table, one way to illustrate how to do so using SQL would be to use an example statement such to the one that follows as an illustration:

PLEASE MAKE SURE THAT USERS WHO HAVE REGISTERED RECEIVE THE FOLLOWING INFORMATION: Your username is "jsmith," your password is "123456," your first name is "John," and your last name is "Smith" (username, password, first name, last name) Examples of PRINCIPLES are "jsmith," "123456," "John," and "Smith."

In order to get the information that is needed from a database, the SELECT statement is going to be used. This statement may be used by you to get just a subset of the columns depending on the restrictions that are provided. You may execute the SQL query that is shown below, which is presented in the following format in order to get a list of all of the users:

SEARCH for users whose identifiers start with the prefix * IN; When you want to alter an existing record so that it reflects new information, you have to use the UPDATE statement. If you don't use that statement, it won't work. In order to put this statement to use, you will first need to determine the column, then the value, and lastly the record id that needs to be modified. Only then can you put this statement to use. After that, you will be able to utilize this sentence. If you were to, for example, perform the following SQL query, it would change the password that is linked with user id 1:

INSERT INTO users VALUES (UPDATE users SET password = "654321" WHERE id = "1"); INSERT INTO users VALUES; INSERT INTO users VALUES; INSERT INTO users VALUES; INSERT INTO users VALUES; INSERT INTO users VALUES; INSERT INTO users VALUES; INSERT INTO users VALUES;

Because there is no other method to remove a record from the database other using the DELETE command, this takes us to our last point. You will need to supply the id of the record in the statement that you are attempting to delete from the database in order to fulfill the requirements of this task. If you were to perform the following SQL query, for example, the user from the database who had the identification number 1 would be deleted:

ALL USERS WITH AN ID OF 1 SHOULD BE DELETED FROM USERS; After you have finished writing the necessary code, you will be able to put your CRUD-capable app through its paces by adding new data to the app's database, modifying existing data, and removing data from the database. You will be able to do this once you have completed the writing of the necessary code. It is possible to get information from the database with the aid of the SELECT statement, as well as assess whether or not the alterations you made were successful.

Either MySQL or JDBC may be used as the backend database management system for a CRUD application that is being developed. Both of these options are accessible to users. You will be able to construct a CRUD application in a short amount of time and with little effort if you just follow the guidelines that are given in this article.

Create an application that will perform CRUD (Create, Read, Update, and Delete) operations on a MySQL database. Demonstrates many features of SQL and JDBC.
