Adaptive Server Enterprise (ASE) is a relational database management system ( RDBMS ) from Sybase, Inc. that runs on Linux and other Unix -based operating systems, Windows NT and Windows 2000 , and Mac OS . ASE evolved from a program originally called Sybase SQL Server, which was first released in the 1980s. Although ASE is a proprietary program, free versions are available.
ASE is designed primarily for use on high-end server s and, according to Sybase, is especially good at handling online transaction processing ( OLTP ) workload s. ASE Version 15, released in September 2005, includes cursor scrolling, messaging services, automatic updating, specialized job wizards, very large server support (VLSS), native storaging and processing of XML documents, enhanced encryption , and a query processing engine.
Prior to 1994, Sybase SQL Server evolved along the same lines as Microsoft SQL Server . Then Microsoft bought a copy of the Sybase SQL server source code and began engineering its product along a different line. A couple of years later, Sybase renamed its product ASE (to distinguish it from the Microsoft product) and released ASE Version 11.5.
