Why is there no equivalent of MSAccess ?
You can do mostly the same with OpenOffice as you can with MS Access. Table design, query design, relation design, forms and reports. The big difference is that OpenOffice doesn’t ship any database (only dbase) with it. You need to choose your own (MySQL, PostgreSQL, MYDB, Adabas D, Oracle, etc. or even the MS Access file). For more information look at the database project site.
