Janus TCP/IP Base

Janus TCP/IP Base is part of the Janus family of products that provides connectivity to the Model 204 database. Janus TCP/IP Base is a pre-requisite for all other products in the Janus family, because without it, it is impossible to use these other products.

The Janus family

A Janus TCP/IP Base site will probably have one or more of the other products in the Janus family, though no others are required. The other Janus products are:

• Janus Network Security, which supports the Secure Sockets Layer (SSL) protocol, providing secure communications for users of Janus products. This is documented in the Janus Network Security Reference Manual.
• Janus Specialty Data Store, which enables Model 204 to operate as a Sybase/Microsoft SQL Server, principally for the Sybase OmniConnect feature of Adaptive Server. Features include optimized translation of SQL into User Language and cataloging tools to map unchanged Model 204 files onto normalized. This is documented in the Janus Specialty Data Store Reference Manual.
• Janus Open Client, which enables your Model 204 User Language applications to invoke Sybase/Microsoft Remote Procedure Calls (RPCs) or language requests (for example, SQL) to one or more Sybase or Microsoft Open Servers and/or SQL servers. This is documented in the Janus Open Client Reference Manual.
• Janus Open Server, which enables you to create Model 204 User Language applications which respond to requests from clients which use Sybase DB-Library Open Client calls and SQL EXECUTE statements. This is documented in the Janus Open Server Reference Manual.
• Janus Web Server, which enables you to provide access to Model 204 data and objects to clients (usually called browsers) via the World Wide Web.

A single Model 204 Online region can contain any number of the three different Janus server products (Janus Specialty Data Store, Janus Open Server, and Janus Web Server). A Janus Open Server or Janus Web Server User Language request can also invoke Janus Open Client $functions; this enables server applications to exchange information with other Model 204 or non-Model 204 servers.
