A relational database management system to which ARC/INFO has access through the DATABASE INTEGRATOR. The Sybase dataserver runs as a single process within the operating system; when multiple users are connected to the database, only one process is managed by the OS. Each Sybase database connection requires 40-60k of memory.
The "total memory" configuration parameter determines the amount of memory allocated to the server. This memory is taken immediately upon startup, and does not increase.
