<database> (RDBMS - relational database management system) A database based on the relational model developed by E.F. Codd. A relational database allows the definition of data structures, storage and retrieval operations and integrity constraints. In such a database the data and relations between them are organised in tables. A table is a collection of rows or records and each row in a table contains the same fields. Certain fields may be designated as keys, which means that searches for specific values of that field will use indexing to speed them up. Where fields in two different tables take values from the same set, a join operation can be performed to select related records in the two tables by matching values in those fields. Often, but not always, the fields will have the same name in both tables. For example, an "orders" table might contain (customer_id, product_code) pairs and a "products" table might contain (product_code, price) pairs so to calculate a given customer's bill you would sum the prices of all products ordered by that customer by joining on the product-code fields of the two tables. This can be extended to joining multiple tables on multiple fields. Because these relationships are only specified at retreival time, relational databases are classed as dynamic database management system. The first commercial RDBMS was the {Multics Relational Data Store}, first sold in 1978. INGRES, Oracle, Sybase, Inc., Microsoft Access, and Microsoft SQL Server are well-known database products and companies. Others include PostgreSQL, SQL/DS, and RDB.

OpenEdge Advanced Business Language

OpenEdge Advanced Business Language, or OpenEdge ABL for short, is a business application development language created and maintained by Progress Software Corporation (PSC). The language, typically classified as a fourth-generation programming language, uses an English-like syntax to simplify software development. The language was called PROGRESS or Progress 4GL up until version 9, but in 2006 PSC changed the name to OpenEdge Advanced Business Language (OpenEdge ABL) in order to overcome a presumed industry perception that 4GLs were less capable than other languages. A subset of the language, called SpeedScript, is used in the development of web applications.

OpenEdge ABL helps developers to develop applications optionally using its own integrated relational database and programming tool. These applications are portable across computing systems and allow access to various popular data sources without having to learn the underlying data access methods. This means that the end-user of these products can be unaware of the underlying architecture.

By combining a fourth generation language and relational database, OpenEdge ABL allows the use of the Rapid Application Development (RAD) model for developing software. A programmer and even end users can do rapid prototyping using the integrated and GUI tools of the development environment.

OpenEdge can be used for:

Microsoft Windows GUI (Graphical User Interface)
WWW Programming (UNIX and Windows)
CHUI (CHaracter User Interface) (UNIX and Windows)
JSON and XML appserver programming (UNIX and Windows)
as well background process programming (UNIX and Windows).
