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.
