[java] J2ME Database

No one?

Do you mean running the database on such system, or merely accessing it remotely?

Many such applications opt for databases located on central servers, and then use internet connections.

What kind of database should that be? You didn't say anything about the table complexity, query language, data store format, does it even need to be persistent?

As such, java.util.HashMap is a database which meets all of the criteria you did list.

I'm not sure how easy it is to access it from J2ME

Original post by Lord_Evil Hi there, Does anyone know of a good J2ME compatible database that meets the following requirements? - free, no shareware or trial version - good performance - preferably portable I'm developing for a Windows Mobile 5.0 device if the database needs to be OS specific. Thanks in advance for your help.

Sorry for not being to clear about my requirements.

The data needs to be persisted on the mobile device since I won't have a central server (yet).

I only have a rough list of what is needed but it should be approx. 4-5 tables. Since the amount of records in those tables could go into the 100s or even 1000s I'd say a mere file based storage (using the record set functionality built into J2ME) would be too slow for queries etc.

The query language itself isn't that important. I'd prefer SQL but that's not a must.

Well, thanks for the hint to MS SQL Server CE, BugHunter. Although it doesn't seem to be portable it should be sufficient for a first try.
