Adaptive Server Enterprise
<database (ASE) The relational database management system that started life in
the mid-eighties [first release?] as "Sybase SQL Server". For a number of years
Microsoft was a Sybase distributor, reselling the Sybase product for OS/2 and
(later) Windows NT under the name "Microsoft SQL Server".
Around 1994, Microsoft basically bought a copy of the source code of Sybase SQL
Server and then went its own way. As competitors, Sybase and Microsoft have been
developing their products independently ever since. Microsoft has mostly
emphasised ease-of-use and "Window-ising" the product, while Sybase has focused
on maximising performance and reliability, and running on high-end hardware.
When releasing version 11.5 in 1997, Sybase renamed its product to "ASE" to
better distinguish its database from Microsoft's. Both ASE and MS SQL Server
call their query language "Transact-SQL" and they are very similar.
Sybase SQL Server was the first true client-server RDBMS which was also capable
of handling real-world workloads. In contrast, other DBMSs have long been
monolithic programs; for example, Oracle only "bolted on" client-server
functionality in the mid-nineties. Also, Sybase SQL Server was the first
commercially successful RDBMS supporting stored procedures and triggers, and a
cost-based query optimizer.
As with many other technology-driven competitors of Microsoft, Sybase has lost
market share to MS's superior marketing, though many consider it has the
superior system.
