Choose your target platform(s).

For each platform you need to support, determine if the API supports that platform. Different APIs support different platforms. If you are doing cross-platform development, choose an API that supports all of your intended targets.

The support matrix found here:  http://www.sybase.com/detail?id=1061806, can be used to identify your development options.

Consider the effects of the following requirements, and then finalize your selection:

SQL Anywhere compatibility   If database compatibility with SQL Anywhere is a concern, consider the following:

Maintaining a common interface may be particularly useful on platforms such as Windows Mobile, where both SQL ANywhere and UltraLite databases are supported. If you need to move from UltraLite to a SQL Anywhere database, you should use embedded SQL or ADO.NET to make application migration easier.

Simplified deployments   If simplifying your UltraLite deployment is an issue, consider programming with the M-Business Anywhere API. Your end-users can download both the UltraLite application and the database concurrently.

Application size   If creating the smallest application footprint is a priority, you should program your application with the C/C++ API. These applications typically yield the best performance and still maintain a small application file size.

Application performance   Each API yields a different performance result. While UltraLite provides high performance in a variety of environments and use cases, embedded SQL and the C++ API are the lowest level of APIs and generally deliver the highest performance.
