SQL...

SQL (Structured Query Language) is a database computer language. It is a tool used for handling relational databases. In simple terms, the language is used for the manipulation of data.

General Information

This language can be utilized in both basic and complex database management. Its functions include basic inputting of data, deletion, reporting, manipulation of data and making complex queries. Computer users will be able to get and display information by typing the appropriate commands.

The language also aids programmers in placing commands into their programs that make it possible to retrieve data. Because SQL is a database administration language, it assists in the definition of database structures. It can also restrict access to the data.

Client/Server Language

As a client/server language, it permits computer software to interact with others on a network with various database servers. The language also becomes the means for retrieving corporate databases in a setting where web servers communicate with program servers.

Distributed Database Language

This means it can assist in the data distribution along numerous interconnected systems. Every computer system utilizes DBMS (Database Management Systems) programs to relay info to one another. This is used for posting requests for data.

In some networks, various types of DBMS are employed. In this case, the Structured Query Language frequently plays the role of a database gateway language. In other words, it helps one DBMS type to communicate with another.

Other Characteristics

Some of the major features of the language include portability along different computer systems and vendor independence. It also has interactive queries, multiple views of data, enterprise application support, client/server architecture and dynamic data definition. The language also has Java integration (JDBC), Internet database access and many more.

In spite of the name, the language is more than just a query tool. The language can be used for sharing data and verifying data integrity. A misconception is that it is a full computer language like C or C++. It isn’t; it is a database sub-language made up of 40 statements.

All these statements are made specifically for managing databases. It is possible to combine it with C, COBOL and other computer languages to extend the capability and its features.

Since its inception, SQL has turned into one of the most vital tools in the computer industry. Its ease of use has made it the standard for enterprise-class data management. For this reason, major technology companies have thrown their support behind it.
