Structured Query Language (SQL) is the standard language for Relational Databases that was developed in the 1970s with the aim to search, insert, update, modify, or delete database records. This standard language is primarily used to manipulate, store, update, and retrieve data from a relational database efficiently. SQL comprises various commands that are segregated into four categories: DDL, DML, DCL, and TCL. Furthermore, SQL enables the users to create and drop various tables and databases, define and manipulate the data, and access, modify, and describe data in RDBMS. SQL is extremely easy to learn and understand. It is widely used in IT sector companies and effectively combines data from various sources. SQL makes data mining faster and allows the users to monitor table and database activities, view updated events, identify specific data at time intervals, and retrieve information based on various requirements. Many such benefits have made SQL a necessity in IT enterprises and have led to a rise in the demand for SQL professionals. Therefore, many institutes offer SQL Server Online Course to help aspiring professionals develop their expertise in SQL and make significant career advancements.
