Part I: Introduction Chapter 2: Relational Databases Chapter 1: Introduction Overview The SQL language and relational database systems based on it are one of the most important foundation technologies in the computer industry today.

Over the last decade, the popularity of SQL has exploded, and it stands today as the standard computer database language. Literally hundreds of database products now support SQL, running on computer systems from mainframes to personal computers and even handheld devices.

An official international SQL standard has been adopted and expanded twice. Virtually every major enterprise software product relies on SQL for its data management, and SQL is at the core of the database products from Microsoft and Oracle, two of the largest software companies in the world. From its obscure beginnings as an IBM research project, SQL has leaped to prominence as both an important computer technology and a powerful market force.

What, exactly, is SQL? Why is it important? What can it do, and how does it work? If SQL is really a standard, why are there so many different versions and dialects? Does SQL really scale from mainframes to handheld devices? Has it really delivered the performance needed for high-volume transaction processing? How will SQL impact the way you use computers, and how can you get the most out of this important data management tool?

For historical reasons, SQL is usually pronounced "sequel," but the alternate pronunciation "S. As the name implies, SQL is a computer language that you use to interact with a database. In fact, SQL works with one specific type of database, called a relational database. Figure shows how SQL works. The computer system in the figure has a database that stores important information.

If the computer system is in a business, the database might store inventory, production, sales, or payroll data.

On a personal computer, the database might store data about the checks you have written, lists of people and their phone numbers, or data extracted from a larger computer system. The computer program that controls the database is called a database management system, or DBMS. Figure This process of requesting data from a database and receiving back the results is called a database query—hence the name Structured Query Language.

The name Structured Query Language is actually somewhat of a misnomer. First of all, SQL is far more than a query tool, although that was its original purpose and retrieving data is still one of its most important functions.

SQL The Complete Reference

SQL lets a user define the structure and organization of the stored data and relationships among the stored data items. SQL allows a user or an application program to retrieve stored data from the database and use it.

SQL allows a user or an application program to update the database by adding new data, removing old data, and modifying previously stored data. SQL can be used to restrict a user's ability to retrieve, add, and modify data, protecting stored data against unauthorized access.

SQL is used to coordinate data sharing by concurrent users, ensuring that they do not interfere with one another. SQL defines integrity constraints in the database, protecting it from corruption due to inconsistent updates or system failures.

SQL is thus a comprehensive language for controlling and interacting with a database management system. Instead, SQL is a database sublanguage, consisting of about forty statements specialized for database management tasks.

Finally, SQL is not a particularly structured language, especially when compared to highly structured languages such as C, Pascal, or Java. Instead, SQL statements resemble English sentences, complete with "noise words" that don't add to the meaning of the statement but make it read more naturally.

There are quite a few inconsistencies in the SQL language, and there are also some special rules to prevent you from constructing SQL statements that look perfectly legal, but don't make sense.

Despite the inaccuracy of its name, SQL has emerged as the standard language for using relational databases.

SQL is both a powerful language and one that is relatively easy to learn. The quick tour of SQL in the next chapter will give you a good overview of the language and its capabilities. You cannot go into a computer store and "download SQL. Components of a typical database management system The database engine is the heart of the DBMS, responsible for actually structuring, storing, and retrieving the data in the database.

It accepts SQL requests from other DBMS components, such as a forms facility, report writer, or interactive query facility, from user-written application programs, and even from other computer systems.
