Sybase jConnect is a pure Java JDBC driver that can be used with SQL Anywhere. Sybase Central and Interactive SQL give you the option to include jConnect metadata support so that you can use the jConnect JDBC driver to access SQL Anywhere databases.
By default, jConnect metadata support is not enabled by the Create Database Wizard for databases being created for Windows Mobile. However, you can choose to enable jConnect metadata support if you require it.
Adding jConnect metadata support to a database adds many entries to the system tables. This adds to the size of the database and, more significantly, adds about 200 KB to the memory requirements for running the database, even if you do not use any jConnect functionality.
If you are not going to use jConnect, and you are running in a limited-memory environment like Windows Mobile, it is recommended that you do not add jConnect metadata support to your database.
