A keyword is a user-defined string that is associated with an object. Any number of keywords can be assigned to an object; keywords can be added and deleted at any time. You can then use the keywords to select objects to process. For more information on methods for assigning and deleting keywords, see Processing Options.…

You can lock an object so that its definition cannot be changed by any ZOM service (until it is unlocked). When an object is locked, it cannot be erased, deleted, destroyed, recreated, moved, renamed, and so on. Locking an object is similar to write protecting the object. You can set and reset the locked property…

ZOM provides many services and features that have been described above for inspecting and manipulating the objects in your application to resolve problems (finding dependent, depending and unreferenced objects and objects that do not exist, for example). In addition, ZOM provides two special services to help you analyze problems in your application: ZOMDiagnose, ZOMViewLog The…

ZOM tags each object with a unique key called the object key. The ObjectKey uniquely identifies an object, even in computing environments where the development tools are not live-linked by means of a network. Some characteristics of the ObjectKey are as follows: ObjectKeys are hidden from the user. ObjectKeys are automatically generated by the tools…

Two advanced selection criteria are described for selecting objects when using the ZOM services. Selection Syntax Description Difference Status p n | ch | r | m Selects objects based on the results of using ZOMDiff or ZOMImport to compute the difference between two different sets of objects, one in the Object Dictionary and one…

Some objects contain persistent data (i.e., EntitySets and relationships with fields). When changing the definitions of objects containing persistent data using the ZOM services, you can choose to have the data preserved or discarded. You indicate that data is to be preserved for an object by setting the datasave property. You can set and reset…

All the ZOM services and features and development approaches mentioned above also apply to single-person development projects as well. In fact, these can be applied to your advantage anytime development is spread across multiple development environments regardless of the number of people involved. For example, there are often several versions of an application representing various…

Another common approach to team development projects is to maintain separate development environments for each developer and synchronize the development environments from time-to-time by merging changes from one environment directly into another. This approach is referred to as peer-to-peer development. Peer-to-peer development is similar to master-slave development except there is no master environment. Each development…
