Standalone components for Version 5 (embedded SQL)

If you are using SQL Anywhere Version 5 as a personal server, with an embedded SQL client application, you are using the following components on your machine:

• A SQL Anywhere Version 5 database.

• The SQL Anywhere Version 5 database engine (personal database server).

• The SQL Anywhere Version 5 interface library.

• A SQL Anywhere Version 5.0 connection string.

The following figure illustrates how these pieces fit together.

Here, the question mark in dbl50?.dll represents a single character indicating the operating system. The interface library is named dlb50t.dll on Windows operating systems.

Embedded SQL client applications make calls to the interface library. The interface library is referenced by name, so that the name dbl50t.dll is a part of the client application.
