  • Creating powerful application with Oracle Database

    Application creation with OracleFor an Oracle application to be built and used rapidly and effectively, users and developers must share a common language and a deep and common understanding of both the business application and the Oracle tools. This is a new approach to development. Historically, the systems analyst studied the business requirements and built an application to meet those needs. The user was involved only in describing the business and, perhaps, in reviewing the functionality of the application after it was completed.

  • SQL - Structured Query Language and developer tools overview

    SQL  overviewSQL was developed by Donald Chamberlain and Raymond Boyce in the early 1970s as a language to retrieve data from IBM's early relational database management systems. It was accepted as a standard by the American National Standards Institute (ANSI) in 1986. SQL is generally referred to as a fourth-generation language (4GL), in contrast with third-generation languages (3GLs) such as C, Java, and Python. As a 4GL, the syntax of SQL is designed to be even closer to human language than 3GLs, making it relatively natural to learn. Some do not refer to SQL as a programming language at all, but rather a data sub-language.
