Before working with tutorials, identify two data sources that you can use for practice. These data sources should not be live or mission-critical, and they should be similar in schema and data. |
A schema archive contains a snapshot of the schema of a registered data source. You compare schema archives against other data sources and archives to identify possible inconsistencies.
A schema archive is generated from a single data source at a specific point in time. Like a configuration archive, a schema archive has versioning functionality and can be periodically updated with the current values of the data source. Older versions are retained and can be recalled as needed.
You create a schema archive using the Schema Archive Job editor. Once created and saved, it is listed in the Data Source Explorer.
To define a schema archive
You can create more versions by clicking the Run Job icon again. |
You can subsequently drag and drop the new archive version from Data Source Explorer to the Source or Target boxes in the Schema Comparison Job editor. You can now run a job using the archive just as you would use a data source.
