Ingres - A
Forgottent Database The Untold Story
Ingres (technically, Advantage Ingres Enterprise) is,
arguably, the forgotten database. There used to be five major
databases: Oracle, DB2, Sybase, Informix and Ingres. Then along
came Microsoft and, if you listened to most press comment (or the
lack of it), you would think that there were only two of these
left, plus SQL Server. [From IT-Director]
Oracle,
Microsoft, and IBM would certainly like the illusion of a 3 horse
race, as this is the only way they can induce Ingres, Informix, and
Sybase users to jump ship, and this, even though database
migrations are by far the most risk prone and problematic aspects
of any IT infrastructure.
