Features

 

SQL/XML-IMDB stores XML documents and relational data in their native structure, meaning that they remain in their natural form, either as complex, hierarchical XML objects (not broken down into tables and columns), or as collection of rows for relational data. When they are stored or accessed there is no conversion of the structures, resulting in unsurpassed store and retrieval speeds.

 

 

 

  • SQL/XML-IMDB's data storage includes compression technology to keep the memory requirement as low as possible.

 

  • String data is always stored in variable length byte arrays and a bool data type requires only one bit.

 

  • The optimizer dynamically re-optimizes plans during execution based on the actual size information of intermediate results.

 

  • Queries can even be further accelerated by the use of prepared statements. Once the result set is ready, data values will be retrieved with speed comparable to linked list operations.

 

  • SQL/XML-IMDB uses a TST-tree as the main indexing algorithm. This algorithm combines the speed advantage of a hash table with the ordered access of a binary tree.

 

  • For XML data, the engine uses Reverse-Lookup indexing and a special Token-Segment-Build-Up indexing mechanism invented by QuiLogic for ultra fast loading and processing of XML files.
