In 1988, Sybase, Microsoft and Ashton-Tate began developing a version of SQL Server for OS/2, but Ashton-Tate left the group later and Microsoft upgraded the system to Windows NT. When the agreement expired in 1993, Microsoft acquired a license for the source code and began selling this product as Microsoft SQL Server.  MS SQL Server and Sybase SQL Server still share many syntactic functions and characteristics. License information allows Sybase system administrators to monitor the number of user licenses used in Adaptive servers. If you activate this setting, only the number of licenses issued will be monitored. It does not apply the licensing agreement. If the license information is set at 0, Adaptive Server does not monitor the use of the license. When license information is set at more than 0, the governess` duty controls the number of licenses used in Adaptive servers during idle cycles. Specify the license information on the number of licenses specified in your license agreement. At the end of each 24-hour period, the maximum number of licenses used during this period is added to the syblicenseslog table.
The 24-hour period is restarted when the Adaptive Server restarts. In 1993, the co-development licensing agreement between Microsoft and Sybase ended and the companies separated while developing their respective versions of SQL Server. Sybase released Sybase SQL Server 10.0, which was part of the System 10 product family, including backup servers, open client/server APIs, SQL Monitor, SA Companion and OmniSQL Gateway. Microsoft continued microsoft with Microsoft SQL Server. If the number of licenses used exceeds the number of license information, Adaptive Server writes this message in the error protocol: Sybase has partnered with The Boeing Company to develop and license Boeings Spatial Query Server (SQS).  This product allows a SYBASE ASE database to optimally store and retrieve data representing defined objects in a geometric space. The SQS is a spatial database. In 2001, ASE 12.5 was released, offering features such as dynamic memory allocation, an EYB container, xml support, SSL and LDAP. In addition, compressed backups, UTF-16 support and several logical page sizes 2K, 4K, 8K or 16K. Sybase, Inc. was a company that produced software and services that created information management and analysis software in relational databases with sites in California and Massachusetts. Sybase was acquired by SAP in 2010; SAP stopped using the name Sybase in 2014.
 ASE is a single-process multithread data server application.
