The default format for the dBase is the *.dbf file. It is commonly used in many applications, where a simple format for storing structured data is needed.
Work with dBase database
- At dBASE III,IV it is necessary to enter table names up to 8 chars at the most (if the name is longer than 8 characters, then the database cannot be opened with the PmDatabase object). Also the column names can have maximum 8 chars.
- The total number of columns is limited in the table.
- dBase files can be created also by saving the data using the PmTrend object (if the Storage type configurator is set to Database dBase backups). In this case the file name is longer than 8 characters, and cannot be opened by the PmDatabase object, but it is readable, for example, by Microsoft Excel program.
The database can be filled:
- by the PmTrend object, if the Storage type configurator is set to to Database dBase backups in this object.
- by the PmAdo object via the ADO Provider Microsoft dBase Driver (*.dbf) or Microsoft.Jet.OLEDB.4.0. or
- by the PmDatabase object.
