At the present moment ObjectLand supports import of files of dBASE format created in database management system: Clipper, dBASE III+, dBASE IV, FoxBASE 2.0, FoxPro 2.0.
Names and number of fields in DBF file and in a table should not necessarily coincide. To set correspondence between fields in DBF file and in a table it is required to perform import setting operation which serves for indicating values of which fields of DBF file should be loaded to which fields of the table. When setting such a correspondence one should take into account the correspondence of data types of DBF file to data types of ObjectLand tables (table 69-1).
Field type of DBF file | Field type of ObjectLand table |
Numeric without fractional part | Integer |
Numeric with fractional part | Real |
Floating point | Real |
Date | Date |
Character | String |
Logical | Boolean |
Memo | String |
