Chapter 1 Overview of Data Structures : Views of Data

Views of Data
First Level: Application View
The application view is the view of data as it is presented to an end user. It is a selective view of data that you as an application developer define.
When you create an application you use many component pieces, for example, presentation screens, input fields, and report writing capabilities. In TIBCO Object Service Broker, all these diverse components are stored as tables. Your application requires all or only some of the data that is defined to these tables.
How Do You Selectively View Data?
You selectively view data by writing programs that reference specific fields within specific tables. Within TIBCO Object Service Broker this construction is referred to as a table.field (t.f) format.
Second Level: Logical View
The logical view is a tabular view of data. You use this view to store and access data. Using a definer, you must define a tabular view of data before an application can use the data.
Third Level: Physical Store
The actual data that your application uses is stored in physical storage devices. The data is accessed via a server layer referred to as the TIBCO Object Service Broker engine. This physical store can contain data known as TIBCO Object Service Broker data that is native to TIBCO Object Service Broker. It can also contain data, known as external data, that belongs to external database management systems (DBMSs) and external operating systems.
