Why SQL is Powerful
Structured Query Language (SQL) is a programming language used to communicate with databases. It is a powerful and complete language used interactively with databases containing hundreds and thousands of stored procedures, views and data. It is used to create and maintain databases. It also is used to manage database security. SQL is used for updating, retrieving and sharing data with users and external applications. If data needs to be ordered or structured in a different view, this can be done with SQL.
The first standard for SQL was introduced in 1986 by ANSI (American National Standards Institute) and ISO (International Standards Organization). It was later expanded in 1989, in 1992 and again in 1999.
SQL is most widely used for relational databases recognizing connections among stored items of information. Since the 1980s new databases have followed the Relational Database Management System (RDBMS) model. It has been the most common choice for organizing congruous data since the days of hierarchical databases. Data in RDBMS systems is much easier to find, display and use, and SQL makes this possible.
SQL mainly consists of English statements, easy to learn and understand. The syntax of these statements can be a hurdle for some new users, but in general it is very easy to read. SQL communicates with databases and gets answers to complex questions in seconds. It can also make changes and deletions just as quickly. Queries, edits and deletes occur in real time due to this interactive nature of the language. One word of caution here, there is no “undo.” Regular backups are good.
SQL runs in many different environments including programs on mainframes, servers, computer workstations, laptops, tablets and phones. It is used for linking the frontend of these devices and environments with the backend databases. SQL databases are designed for portability, and they can be moved from one device to another with ease. They have become ubiquitous in business. They provide server architecture which allows multiple users to access the contents at the same time while making dynamic updates. The language is powerful enough to be used in enterprise applications around the world. Highly versatile, SQL supports object oriented programming, integrates with Java, and is used in internet applications.
