| A <var class="product">Janus TCP/IP Base</var> 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:
| |
| <ul>
| |
| <li><var class="product">Janus Network Security</var>, which supports the Secure Sockets Layer (SSL) protocol, providing secure communications for users of Janus products. This is documented in the [http://www.sirius-software.com/maint/download/jansslr.pdf Janus Network Security Reference Manual].
| |
| </li>
| |
| | |
| <li><var class="product">Janus Specialty Data Store</var>, which enables <var class="product">Model 204</var> to operate as a Sybase/Microsoft SQL Server, principally for the Sybase OmniConnect feature of Adaptive Server. Features include optimized translation of SQL into <var class="product">User Language</var> and cataloging tools to map unchanged <var class="product">Model 204</var> files onto normalized. This is documented in the [http://www.sirius-software.com/maint/download/jsdsr.pdf Janus Specialty Data Store Reference Manual].
| |
| </li>
| |
| | |
| <li><var class="product">Janus Open Client</var>, which enables your <var class="product">Model 204</var> <var class="product">User Language</var> 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 [http://www.sirius-software.com/maint/download/joclr.pdf Janus Open Client Reference Manual].
| |
| </li>
| |
| | |
| <li><var class="product">Janus Open Server</var>, which enables you to create <var class="product">Model 204</var> <var class="product">User Language</var> applications which respond to requests from clients which use Sybase DB-Library Open Client calls and SQL EXECUTE statements. This is documented in the [http://www.sirius-software.com/maint/download/josrvr.pdf Janus Open Server Reference Manual].
| |
| </li>
| |
| | |
| <li><var class="product">[[Janus Web Server]]</var>, which enables you to provide access to <var class="product">Model 204</var> data and objects to clients (usually called browsers) via the World Wide Web.
| |
| </li>
| |
| </ul>
| |
| | |
| A single <var class="product">Model 204</var> Online region can contain any number of the three different Janus server products (<var class="product">Janus Specialty Data Store</var>, <var class="product">Janus Open Server</var>, and <var class="product">Janus Web Server</var>). A <var class="product">Janus Open Server</var> or <var class="product">Janus Web Server</var> <var class="product">User Language</var> request can also invoke <var class="product">Janus Open Client</var> $functions; this enables server applications to exchange information with other <var class="product">Model 204</var> or non-<var class="product">Model 204</var> servers.
