Prepare the Insfrastructure Part 3 – Before you start the SQL injection action, we recommend you know first what SQL is and how to use it. SQL stands for Structured Query Language, is a language used to access data in a relational database. While the relational database itself is a database that works by linking data in different files using a key or element general data. Simply put, the data processed by SQL is in the form of information stored in tabular form. Every table has certain fields to store data or information. SQL is also known as the standard language to use access the database server. Even today almost all servers the existing database supports this language to perform data management. SQL is widely applied to based programming client-server, such as PHP, ASP, Java J2EE, and so on. Example Well-known SQL software are MySQL, MSSQL (Microsoft), Oracle SQL, Postgre SQL (open source). Basic SQL commands on basically the same, be it MySQL, Postgre SQL, MSSQL, or Oracle SQL. In general, SQL commands are divided into two groups, that is :
- DDL (Data Definition Language)
Data Definition Language is a part of SQL which is used to define data and database objects. Command it is in the form of creating, modifying, deleting the database along with other objects in the database, such as tables. Some examples of SQL commands which include Data Definition Language
- DML (Data Manipulation Language)
Data Manipulation Language is part of the SQL command that is used to manipulate data in a table.
Enough theorizing about SQL. Now we will try to use the database. First of all, after you managed to turn the computer into a web server, now we’re going to start using the database.
