In this article, we will discuss the advantages of SQL. We have already seen the several features of SQL in characteristics of SQL. Here, we will cover some of the advantages that we get while using SQL as a database language.
1. Fast Response Time
You can quickly retrieve large amount of data from database using SQL. The response time of a SQL query is very fast.
2. Requires No coding
Learning SQL is easy and doesn’t require any prior coding or programming knowledge. The syntax of SQL is very simple and close to english so learning curve is smooth.
SQL is portable, it supports various operating system and devices. SQL statements can be stored as saved procedures and these procedures can be used on a different machine to perform the same task without needing to rewrite the statements again.
4. Standardised language
SQL is been used for over the years and has wide variety of well maintained documentation. This language is so standardised that the same syntax can be used on various different platforms.
SQL server can connect to third party backends like Oracle, IDM Db2, MySQL etc. using drivers. These drivers allow the smooth integration.
SQL allows to set permissions in tables, this makes it secure as a user with no permission cannot read, write or modify the data in database. SQL also has the concept of constraints that ensures what type of data can be inserted into the tables. All these features make SQL a secure database language.
It is easy to add or drop tables in the database using SQL. Also, the database size doesn’t affect the performance of SQL that much and it works pretty great with large databases as well. It is easy to add several new tables into the database as well as drop multiple tables from database.
8. Supports Transactions
Transactions are the logical units or sequence of tasks that either needs to be completed fully or none to maintain database integrity. SQL commands such as COMMIT, ROLLBACK, SAVEPOINT etc. support transactions.
