Defining database users

Until version 11.70.xC2, Informix^® database users must be created at the operating system level and be members of the 'informix' group. Starting with 11.70.xC2, Informix supports database-only users with the CREATE USER instruction, as most other db servers. Any database user must have sufficient privileges to connect and use resources of the database; user rights are defined with the GRANT command.

Before a user can access an Sybase ASE database, the system administrator (DBA) must declare the application users in the database with the GRANT statement. You may also need to define groups in order to make tables visible to other users.
