Besides, when querying
the XML document, it is also necessary to translate a query into an SQL statement, and execute join operations repeatedly among different relation tables, so that it exposes lower efficiency.

Object evolution in a Temporal Database can be querying

2.2.5 Ontology Storage and Querying
. A number of research groups are currently working on the development of inferencing tools and deductive query engines to enable the deduction of new information or knowledge from assertions or metadata and ontologies expressed in formal ontology languages (RDE DAML+OIL, or OWL).
It characterizes a business situation for which management wants information of the kind that accountants might be asked to produce by querying
a database (Borthick 1992).
Most applications built on relational databases incorporate a querying
tool known as query-by-example (QBE), which uses a graphical approach to construct queries.
For this reason we do not show results for CPU time.) For TOS processing there were 10,000 (or 10K) accumulators for index building and querying
, or about 2% of the total number of documents, a figure that gives effectiveness similar to that of ordinary TO processing.
Both of our database systems support storage and querying
of compressed text, but, since the compression schemes are not compatible, in this article we use both in uncompressed mode, to ensure that the same amount of data is being fetched and to allow direct comparison of retrieval times.

With computers, "you can now index all of the words in a document" for full-text querying
, Marcus notes.
The concept of data mining as a querying
process and the first steps toward efficient development of knowledge discovery applications are discussed.
Besides, the Structured Query Language (SQL) is the most popular, basic and the standard query language for managing and querying
