Client/Server - Heterogeneous Environments


Access to remote databases in client/server environments is totally transparent within Mimer SQL. An application, developed against a local database, can be directed to access a remote database without changing one single line of code. In the application, databases are referred to by a logical name. These are mapped onto actual databases (either local or remote) by the Mimer SQL system, using mappings set up by the database administrator.

By introducing a logical database concept, the physical location of the database is hidden from the user. When an application connects to a database by its logical name, the database location and communication protocol to be used are determined by the Mimer SQL system.

Mimer SQL supports heterogeneous environments, where UNIX, Open/VMS, Windows NT/2000, Windows 98/Me computers can be freely mixed on a network. Mimer SQL's use of a standardized format for data storage eliminates any need for conversion in the data transfers between servers and clients, making the communications very fast and efficient.

One single application can also access several different databases (local or remote) simultaneously.

When running in Client/Server mode Mimer SQL uses TCP/IP or Named Pipes protocols. Mimer SQL Clients utilize the WinSocket 2.0 standard for TCP/IP communication.
