Introduction To Sql

Structured Query Language (SQL)

The Structured Query Language, SQL, has emerged in recent years as the standard query language used with relational databases. The SQL language has gained ANSI (American National Standards Institute) and ISO (International Standards Organisation) certification and a version of SQL is available for almost any computer system, from a Cray supercomputer to a PC. There is now a growing need for a clear, basic introduction to SQL and its applications. The author sets the scene with an introduction to relational databases and a brief history of the development of SQL. The language is then presented in an overview chapter which describes the functions of the major SQL commands and gives the reader an idea of the power of the language in creating, populating, querying and modifying database tables. Later chapters focus on explaining each of the SQL command groups more fully. The order of topics is carefully chosen as many SQL commands build upon others.

Introduction to SQL

The DNA category covers all the technologies involved in building applications in a Windows environment. There is a strong web emphasis here, but Wrox books in this category also cover non-Microsoft technologies that come under the DNA umbrella - such as XML - and database technologies like SQL Server and Access. This tree shows the database section of the DNA technology world. SQL (Structured Query Language) is a way a programmer's application can talk to any database, and customize it. SQL has the advantage of being easy to use and is well tested; it's the logical link between web pages and data storage. It is platform-independent and the primary interface for both Microsoft SQL Server and Oracle. SQL is a rare thing: it's a long standing industry standard, and is completely compatible with its earlier versions. It will remain the standard for years to come.
