SQL or Structured Query Language is one of the most popular and powerful programming languages used in a relational database management system. To understand what SQL is, first, you should know what a database is. A database is a collection of information for easy access, management, and maintenance. We should also know that data is. Data deals with certain facts like numbers, integers, decimals, characters, and Boolean values. As you have such a large pool of data, you need to store that data. Especially in the 21st century, as we all use social media and terabytes of data are generated in a second. To deal with such a large amount of data, we have to store that data. Thus, we need the use a database. A database will store and manage the data efficiently. To illustrate with an example, suppose we have a company, and we have a large number of employees in the company. And, we have a large number of departments in the company. To store all data of the company in one place, a database is required. Suppose, in the company, you have a sales department, marketing department, technical department, etc. Each department in the company will have a large amount of data. A database will collect all the amount of data in each department and will store it in separate tables. Examples of databases include telephone directories, customer data, product inventory, etc. Whenever you work with a database, there must be a logical structure for it. This is called the data model. Generally, data models can be broadly classified into 2. The first one is an object-based logical model and the second one is called a record-based logical model. Let me first explain the object-based logical model. An object-based logical model is a blueprint of your database. Suppose you take an employee database, you must have an idea of the blueprint. You must know how different attributes of employees are related, and what the relationship between employee and department is. You know about all these, you should have the blueprint. This blueprint is called the entity-relationship model. An entity relationship model is a type of object-based logical model. The entities here will be tables. You must know that when we talk about an employee, an employee is an entity. Department is also an entity. To know about the relationship between entities, you should make an entity-relationship model. To illustrate the record-based logical model, it is our blueprint. We have to implement these models and we implement them through records. There is another type of data model called the relational data model. The relational data model is the process of storing data using columns and rows. Each column will define a specific attribute. For example, when we look into details of the employee like age, gender, etc, these data are stored in columns. A row gives you information on all the details of the employee. For example, name, employee ID, salary, and all details will be illustrated. Thus, the relational data model is the process of storing the data in the form of rows and columns. Another data model is the hierarchical data model. This data model is illustrated in the form of a tree-based structure model. When we talk about the network data model, it is a data model in the type of graph. Thus, there are different features of data models of a database.

Another section to look into is DBMS. DBMS expands to the database management system. If you have a database with you, and if you need to deal with that database efficiently, you need a management system and DBMS is an effective management system that can be used for this. There are different types of database management system operations or DBMS operations. Those are adding new files, inserting data, retrieving data, modifying data, removing data, and also removing files. So, if you are a student or professional and if you pursue an SQL career, you will come across all these basic aspects of SQL like data, database, and database management system or DBMS.

Versions of SQL (Structured Query Language)

Microsoft introduced SQL (Structured Query Language) in 1974. This programming language was designed by Donald D. Chamberlin and Raymond F. Boyce and is considered to be the strongest database language in the world. There were many versions of SQL (Structured Query Language) introduced by Microsoft over the years. The first version of SQL (Structured Query Language) is SQL Server v1.0 released in 1989. Since then, many versions of MS SQL was released. The latest version of SQL (Structured Query Language) introduced in the market is SQL Server 2022 which was released in 2022.
