Chapter 1 Overview of Data Structures : Your Data Store

Your Data Store
What is Your Data Store?
Your data store is any data that can be accessed from a TIBCO Object Service Broker system. In TIBCO Object Service Broker, your data is stored in a Pagestore. Other DBMSs use their own storage structures. Your data can reside on your TIBCO Object Service Broker local or remote node, or in files and databases external to TIBCO Object Service Broker. This data can be persistent or transitory (non-persistent) in nature. For more information on the Pagestore, refer to Storage of TIBCO Object Service Broker Data.
Stored Types of Data
The type of data that you access determines the range of operations and behavior that your data exhibits. You can access both TIBCO Object Service Broker and external data.
TIBCO Object Service Broker Data
TIBCO Object Service Broker data is data that belongs to TIBCO Object Service Broker. TIBCO Object Service Broker determines its storage, allowable syntax and semantic type, and accessibility. It is physically stored as a table in the Pagestore. You can access Pagestores that are local or remote to your node.
External Data
External data is data stored outside of TIBCO Object Service Broker. An external operating system or DBMS controls its storage, its syntax and semantic type, and some aspects of its security. The physical storage structure of the data depends on its DBMS or operating system. TIBCO Object Service Broker uses an additional definition layer to translate the logical structure to the physical structure. This definition layer is provided through the appropriate Table Definer.
Persistent Data
Persistent data is data that is physically stored in a storage device. This data can be either TIBCO Object Service Broker or external data. Data that is accessed via the following types of tables is persistent in nature:
Accesses CA‑IDMS data.
Contains data stored in the default TIBCO Object Service Broker format.
Non-persistent Data
Non-persistent data is data that lives only for the duration of a TIBCO Object Service Broker session or transaction. The data is based on some other data and is not stored in a physical storage device. The following table types are used for data that is non-persistent:
Holds data in Execution Environment level storage. The data lasts for the duration of the Execution Environment.
It is used to display a text-based screen via a display statement within a rule. The data lasts as long as your transaction unless a DISPLAY & TRANSFERCALL statement is used in as the display statement, in which case the data is brought into the subsequent transaction.
