CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda):: A multidimensional access method offering significant performance increases by intelligently partitioning the query space is applied to relational database management systems (RDBMS). We introduce a formal model for multidimensional partitioned relations and discuss several typical query patterns.

Multidimensional or Relational. 3 Even people with the smallest short-term memory will remember these five words. Codd's expression, On-line Analytical Processing, is useful when we want to emphasize the differences between On-line Transaction Processing (OLTP) and OLAP.

ILYAS, GEORGE BESKALES and MOHAMED A. SOLIMAN David R. Cheriton School of Computer Science University of Waterloo E–cient processing of top-k queries is a crucial requirement in many interactive environments that involve massive amounts of data.

In this paper, we investigate the efficiency of different proposed schemes for storing and querying various kind of graphs using the relational infrastructure. Moreover, we investigate how existing relational query optimization techniques could be effectively utilized to improve the processing times of relational-based processing of graph by: 6.

Pub. date January Author Markl, V. Volume 59 Price US$34 / € A relational database is a digital database based on the relational model of data, as proposed by E. Codd in A software system used to maintain relational databases is a relational database management system (RDBMS).

Many relational database systems have an option of using the SQL (Structured Query Language) for querying and maintaining the database. Proposed query processing technique supports an efficient evaluation of the star joins and grouping operators known as the most frequently used but very expensive operators in OLAP queries.

The MA index is a variation of the path index in object databases and supports index-only processing for the star joins and grouping by: 6.

Efficient storage and query processing of data spanning multiple natural languages are of crucial importance in today’s globalized world. A primary prerequisite to achieve this goal is that the principal data repositories, relational database systems, should efficiently and seamlessly support multilingual data.

The value of α* depends on the training workload and the data distribution of the relation. The histogram-based approaches can guarantee the retrieval of all.

The Logical Multidimensional Data Model. The multidimensional data model is an integral part of On-Line Analytical Processing, or OLAP. Because OLAP is on-line, it must provide answers quickly; analysts pose iterative queries during interactive sessions, not in batch jobs that run overnight.

comprised of on-line analytical processing (OLAP) systems that handle large transactions and complex queries. A significant portion of data warehousing applications comprises relational queries that, in turn, are based on a mix of arithmetic and relational algebra (RA) operators.

Since they process a substantial amount of data, these operators. Abstract. Efficient query processing is one of the basic needs for data mining algorithms. Clustering al-gorithms, association rule mining algorithms and OLAP tools all rely on efficient query processors being able to deal with high-dimensional data.

Inside such a query processor, multidimensional index structures are used as a basic Size: KB.

Traditionally, relational DBMSs have relied on well-known access methods, such as the ubiquitous B+-tree, hashing with chaining, and, in some cases, linear hashing [52].

Object-oriented and object-relational systems have also adopted these structures to a. relational database systems, most of them are applicable to and useful in the query processing facility for any database management system and any data model, provided the data model permits queries over “bulk” data types such as sets and lists.

queries, and reports listed below a table name. Then another table and its objects display. You notice some of the object names are repaed under different tables. Relational database management system (RDBMS).algorithms for queries (exact query, range query, nearest neighbor query and spatial join) using spatial access methods have been studied in the literature.

Here, we show how these bounding functions and searching strategies perform when they are included in branch-and-bound algo-rithms for a special distance-based query, the K closest pairs query.for spatial intersection queries performed on the Relational R-tree.

In [2] it is also shown how our approach can be adapted to similarity range queries and k-nn queries on the Relational M-tree. For more details about relational index-ing, we refer the reader to [1]. .
