Disclosed is a technique for processing a base model. The base model is received. Then, the base model is used to create a ViewType comprising a ViewType object, one or more ViewList objects corresponding to classes in the base model, and one or more ViewElem objects corresponding to attributes in the base model.

Disclosed is a technique for manipulating instance data of a base model. A ViewType, a root object representing an object of the base model, and an operation are received. Whether the ViewType and the root object are compatible is determined. When the ViewType and the root object are compatible, the operation is applied to the instance data of the base model while using the ViewType to traverse the instance data.

Disclosed is a technique for generating a relational view. Initially, identification of a base model, a relational schema, and a ViewType are received. Then, a statement to create a relational view of the instance data for the base model using the ViewType is automatically generated.

Method and means are described for encoding and decoding stored units of data representing entity/relationship (E/R) data, function calls, and file data by including a prefix with each unit of data which includes a length code, an action code, and a unit identifier code. The data units with prefixes are organized into a data stream by using rules described in a formal grammar. The data stream will typically be transmitted to another program inside the computer or to another computer host or programmable workstation (PWC). When received the data stream is parsed back into data units by reversing the encoding process. After the data units are recovered the appropriate action is taken to process the units. E/R data is entered into or updated in a repository, function calls are passed on to an E/R repository function or other program along with the specified parameters for execution, and file data is stored in standard files. Generated output is captured, encoded into a data stream and transmitted back to requesting PWS which then parses the data stream to recover the output data.
