|Embarcadero DB Change Manager XE2 - Frequently Asked Questions|
One possible definition: the process by which the structures, settings, and data within a database may be tracked and managed over time: across physical environments like test, development and production, and back to-as well as forward from-the design layer.
Use DB Change Manager XE2 to capture archives and then run a comparison of the live database against those archives for tracking changes or diagnosing problems in Production. Simply schedule regular schema archives using the flexible object selection features to make sure you capture exactly what you need to track. Then run or schedule regular compare jobs to track schema and database configuration changes. New in Change Manager 5.0 is the ability to run one-to-many data, schema, and configuration compare jobs.
How does DB Change Manager XE2 help with rolling out application updates or a patch for a packaged application?
A: Use DB Change Manager XE2 archive and compare features to find out how the roll out will impact the database. It is a simple, nearly automated process that saves time and reduces errors. All you have to do is create an archive using the object refinements feature to select components that you need. Then generate a change script - the change script will generate create, alter, and/or drop statements, automatically accounting for dependencies and preserving data when the change requires a table to be recreated.
There are a number of ways that DB Change Manager XE2 can help streamline the development process. First of all, developers can capture changed objects and then generate change scripts that automatically account for dependent objects. This saves analysis time and reduces the possibility for errors because they do not have to figure out the correct syntax for the particular database version they are using.
DB Change Manager XE2 capture and comparison features let developers track and report on complex iterations of scripting to preserve data. And keeps an accurate history of all work to generate reports or revert back to previous states, and create reports to communicate with data modelers and DBAs, or just to report status. Source code control support and integration further enhance collaboration and workflow.
DB Change Manager XE2 is packaged in "Editions" that are tailored to the needs of database developers and DBAs. The Developer Edition is geared toward the needs of the developer, and include: schema and data compare functionality; advanced alter generation and object filtering; as well as source code control integration. The Pro and Enterprise editions are primarily oriented towards DBAs and include email notification (as well as pluggable user-defined notification), advanced configuration auditing features and unlimited datasources. DB Change Manager XE2 Enterprise is the same as Pro, but with a command line API.
