Schema Modeling

Valid for: yuuvis® RAD version 6.x

All work with yuuvis® RAD begins with a data model – the yuuvis® RAD schema. The schema is part of a project and is created in yuuvis® RAD designer.

The schema is used to develop object type groups (folder and document types) via which users create and manage business objects.

Object Types, Index Data, and Document Files

An object type identifies a business object by means of specific index data which can be used to find and identify folders and documents. Index data describes the properties of a business object. For example, an invoice document is defined by its invoice date, invoice number, and vendor/customer. Specifications can be made for the index data by setting up catalogs for indexing, for example. Catalogs are lists with object-specific entries. Document files can be assigned to documents, in addition to index data.

Object Types and Groups

Object types can be grouped together to create a better overview (e.g., specialist applications). For example, an object type group consists of a folder type and any document type. Default settings can be specified for document types, for example, the number of documents of one type that can be created.

Folder Structure of a Schema

Object Types

You can create object type groups in this project area. For example, an object type group contains a folder type and any document types.

Abstract Object Types

Abstract object types are a template for other object types. Fields for abstract object types are part of the derived object types and are edited using the abstract object types in the schema.

Catalogs

Catalogs provide drop-down lists for the index data fields of business objects. Catalogs can be lists of titles, departments, and business locations.

Counters

Any number of counters, which can be used for the sequential numbering of objects of an object type, can be configured for the schema.
