Mail merge tool in PostCast can use any database format. However, some database features in PostCast work only with Microsoft Access databases. To use all the tools in the program, you should use database wizards under the Tools menu to create a new PostCast database and import your existing data.
BaseNow, our other product, works with all database formats. It supports Oracle, Microsoft SQL Server, Access, Excel, and all other ODBC and OLEDB compatible databases. The program can simultaneously display an unlimited number of heterogeneous databases, all combined in an intuitive user interface. It is very easy to transfer the data from one database to another - all you need to do is use the copy and paste operations just like in any text editor.
