A dictionary baseline contains a set of database definitions captured at a certain time. Baselines are useful because they can be used to track changes to a database. A dictionary baseline version can be compared to another dictionary baseline version, or to a database. More information is available at About Dictionary Baselines.
Different baseline comparison scenarios are:
Compare a specific baseline version (representing a well-defined point in the development of an application, for example) to the current definitions in the database. This tells you how the database has changed since the well-defined point. This is a baseline-database comparison.
Compare the most recent baseline version to a specific baseline version (again, one that represents a well-defined point in development). This tells you what has changed since the well-defined point. Do this if you are capturing new baseline versions regularly.
Compare the latest baseline version to the previous version. This tells you what has changed since the last baseline. Do this if you are capturing new baseline versions regularly.
