Merging changes from one development environment into another is done by exporting the changes from the first (i.e., source) environment using ZOMExport and then importing these changed objects into the second (i.e., target) environment using ZOMImport. The import process compares the incoming objects from the source environment with the objects in the target environment. New…

When working on a team development project, you should first adjust the configuration of ZOM for each development environment so that objects from the various environments can be easily identified. The three configuration options of importance here are the environment code, the new keyword, and the changed keyword. You configure ZOM using the ZOMConfig command.…

Zim contains a number of fixed object types. The objects in any application depend on each other in various ways. These dependencies among objects form a network of interrelationships. An EntitySet, for example, depends on its fields. If the definition of a field changes, then the definition of the EntitySet changes. A relationship object depends…

The object dependency information can also be used to select un-referenced objects that are not used by any other object. In our example, there are three un-referenced objects: pMainMenu, PlacedBy and vJunkVar. Un-referenced objects can be selected using the “u” selection criteria, as shown in the following example: ZOMList +p u Objects Found by Unreferenced…

Dependency implosion is the process of finding the objects which depended on (i.e., used) by a given object, and so on down the dependency tree. There are three different kinds of implosion: immediate, creation, and program. As an example, to list all of objects that are used by pMainMenu, enter ZOMList pMainMenu +i The result…

Dependency Explosion is the process of finding the objects which depend on (i.e., uses) a given object, and so on up the dependency tree. There are three different kinds of explosion: immediate, creation, and program. As an example, let’s suppose we want list all of the objects that use Customers: ZOMList Customers +x The result…

Objects are imported using the ZOMImport command. ZOMImport imports all objects described in the ASCII files produced by ZOMExport. Therefore, before you can use ZOMImport, you must first place the ZOMExport files in your database directory. Then, to invoke ZOMImport, enter ZOMImport You can also import Z41 files that are compatible with older versions of…

Objects are exported using the ZOMExport command. The objects to export are identified using the normal object selection criteria. For example, suppose you have associated all the objects you want to export with the keyword “To_Export”. The following command exports these objects: ZOMExport +k To_Export ZOMExport builds a series of ASCII files containing the object…

ZOM provides two special services for exchanging objects between separate development environments. Objects are exported from one environment using ZOMExport and imported into another environment using ZOMImport. These services use a machine-independent ASCII file format to exchange objects. Objects being exchanged retain their object key identification. The object key enables ZOMImport to compare the objects…

For ZOM to know about an object, the object must first be registered. The registration process requires no effort on your part since registration is automatic and occurs when you use a ZOM service. Each ZOM service quickly searches for any unregistered objects and registers them in the knowledge base. When an object is registered,…
