Value-based system architecture stores and manages three basic sets of objects: a data dictionary holding metadata, indexing and linking data sets, and actual data values made up of stored information. The independent logical file database and relational databases are value-based. A dynamic DBMS is...
In this paper, a novel indexing technique for the approximate solution of k – NN problem is described and analyzed. The construction of the indexing tree is based on clustering. Indexing structure is implemented on top of high-performance industrial DBMS....
(dbms) and implementing optimized data retrieval and storage techniques. by leveraging indexing, caching, and efficient database querying strategies, dynamic websites can retrieve and display relevant data quickly, even when dealing with large datasets. additionally, proper database design and ...
In this work, DISC is proposed to process encrypted queries directly on encrypted data, in order to keep the data and query results confidential from adversaries. It is required to have a balance between data confidentiality and query execution. A spatial indexing structure is built to provide ...
His current focus is on the IBM DBMS products and, in particular, the Informix database products. Dick also supports related areas, such as information integration and high availability solutions. Ravi ViJay is a systems software engineer in the IBM India Software Labs, working primarily on new ...
As we saw in Part I, an SQL statement may be deemed to NOT use an index in the Automatic Indexing deliberations, where it is actually used in normal database sessions (and perhaps incorrectly so). Where the data is heavily skewed and current statistics are insufficient for the CBO to accu...

There are many indexing techniques known in the art. An inverted index is the indexing technique of choice for most web documents. Search engines use an inverted index for HyperText Markup Language (HTML) documents, and Database Management Systems (DBMS) use it to support containment queries in...
27. A method according to claim 25 further comprising indexing the file structure so as to construct the database. 28. A method according to claim 27 wherein the indexing is performed asynchronously with respect to the remaining steps.
