Information: Development History of Sybase, a database vendor

Sybase was founded in 1984The company name "sybase" is taken from the meaning of "system" and "Database. Bob Epstein, one of the founders of Sybase, is a major designer of the INGRES Emy edition (relational database model product in the same period as system/R.

Sybase's first relational database product isSybase sqlserver1.0 launched in May 1987. Sybase first proposed the idea of the Client/Server database architecture and first implemented it in Sybase sqlserver.

When talking about the Ingres Database, I have to mention Michael Stonebraker, the founder of Ingres. He is a professor at UC Berkeley and a famous database scholar. He proposed the object relational database model in 1992. Professor Stonebraker leads the post-INGRES project called ipvs. The results of this project are enormous and have contributed a lot in many aspects of modern databases. Professor Stonebraker has also done a thing that benefits all mankind, that is, he put ipvs under the protection of BSD copyright. Nowadays, PostgreSQL has become the name of Postgres, and its functions are becoming increasingly powerful. I also like this database very much. You can freely browse itCodeLibrary, you can understand the idea of the first-line project in real time.

In 87 years, Sybase felt that it was difficult to keep SQL Server (not called ASE at that time) as the boss by relying on one power alone, so it was jointly developed by Microsoft. As to where the original code comes from, this should be related to Ingres. Later, on December 31, 1994, the cooperation between the two companies was terminated. By now, you should have a set of identical SQL server code.

As you can imagine, Sybase continues to develop and port Sybase sqlserver to various platforms. The version also changes from 4.2 to 11.0.

Later, Sybase sqlserver was renamed Sybase ASE (Adaptive Server Enterprise) to distinguish it from Microsoft's ms SQL Server. In fact, Microsoft should be renamed. The original owner of the Code is Sybase, and the official name is Microsoft. This transaction is indeed a loss. However, ASE is easy to remember, and the first three letters of Sybase are replaced by ASE.

ASE has now developed to version 15.0.2. The numbers 13 and 14 are not good for laomei, so they jumped from 12.5.4 to 15.0. It is estimated that Oracle will be named like this in the future.

Currently, Sybase's product policy has been adjusted. In the mobile database market, its ASA (SQL Anywhere) occupies an absolute leading position, with more than 70% of the market. At the same time, Sybase ASE maintains the status of large database vendors. It has a strong market in fields such as telecommunications, transportation, municipal administration, and banking. Its products are all supported by multiple platforms.

Sybase ASE separates the replication server and Sybase IQ among other important products, which is equivalent to further dividing the large database market.

Calculate, ms SQL server should be considered Sybase ASE compatriot brother, however, ASE lineage is more pure. No matter who is more successful, it proves that the original SQL Server is still alive, and it still has powerful vitality.
