Convert DB2 to DBT

Understanding db2 and dbt file formats

DB2 files are typically associated with IBM's DB2 database system, which is a relational database management system (RDBMS) used for storing, retrieving, and managing data. These files may contain database tables, schemas, or exported data in a proprietary format.

DBT files, on the other hand, are most commonly known as dBASE memo files. They store large text or binary data associated with dBASE database tables (DBF files). The DBT file format is used to hold memo fields that exceed the standard field length in DBF files.

Why convert db2 to dbt?

Converting from DB2 to DBT is typically required when migrating data from an IBM DB2 database to a dBASE-compatible system, especially when memo fields or large text fields need to be preserved in the dBASE format.

How to convert db2 to dbt

There is no direct, one-step converter for DB2 to DBT due to the differences in database architectures. The conversion process generally involves exporting data from DB2 and then importing it into a dBASE-compatible application that can generate DBT files.

1. Export data from DB2: Use IBM DB2 tools to export your tables, including memo or large text fields, to a common format such as CSV or SQL dump. For example, use the command line: db2 export to mytable.csv of del select * from mytable.
2. Prepare the data: Ensure that memo fields are properly formatted and separated, as these will be mapped to memo fields in dBASE.
3. Import into dBASE or compatible software: Use a tool like dBASE Plus or DBF Manager to import the CSV or SQL dump. During import, map the appropriate fields to memo fields so that a DBT file is generated alongside the DBF file.

Recommended software for db2 to dbt conversion

• dBASE Plus: A comprehensive dBASE database management tool that can import data and create DBF/DBT files. Use File → Import to bring in your exported data and map memo fields accordingly.
• DBF Manager: Allows importing CSV and creating DBF/DBT files. Use File → Import → CSV and ensure memo fields are set up.
• Full Convert: A commercial database migration tool that supports DB2 and dBASE formats, automating much of the conversion process.

Tips for a successful conversion

• Always back up your original DB2 data before starting the conversion.
• Check field mappings carefully, especially for memo fields, to ensure data integrity.
• Test the resulting DBF/DBT files in your dBASE application to confirm all data has transferred correctly.
