SysDB 0.2 for Mac was available as a free download on our application library. The application relates to Developer Tools. The actual developer of this software for Mac is Sysalys.
From the developer:
SysDB allow to synchronize your XML data (based on XML Schema) with a relational database.
What's new in this version:
The new version is now limited to 500 records in database, but there is no more time limitation. SysDB is now able to manage encodings for XML DATA files (but for schema files, there is a technical limitation to UTF-8 due to the parser).
You may want to check out more software for Mac, such as STEPS_DOMAIN_Software_Watch My Domains or Ask Oscar, which might be similar to SysDB.
