Glossary

If you want to define a number of terms specific to your project then you may want to use a glossary.

A

abstraction
Refers to the decoupling of how information is presented to information consumers (users or applications) from how the information is represented in underlying data sources. Abstraction is achieved through two key technical capabilities: federation and modeling.
Teiid provides information abstraction through the use of relational and XML views, which are defined in the Designer and packaged in VDBs for execution by the query engine.
access pattern
Constraints imposed on criteria for particular columns in order for a query to be processed. Often, these criteria are imposed by different (non-JDBC) data sources.
Teiid provides the means to define access patterns in models using the Designer, which are then enforced when processing queries by the query engine.

B

batch
A set of records returned in response to a query.
batched updates (SQL)
The batch update feature allows multiple update operations to be executed at once as a single batch, rather than as independent operations. In some cases, this can greatly improve performance.
BLOB
Binary large object. This is a term commonly used in relational DBMS systems.
Teiid supports querying and updating of BLOBs and CLOBs.
bootstrap properties
The set of properties required for a system to start up.

To do this simply enter the following <div> element using a RichText / HTML paragraph.

To help browse the glossary a lot of anchors tags <a> are used. These take the form <a name="X" id="X" class="anchorfix"></a> and are referenced using <a href="#X">X</a>
