Data warehouse might be implemented on relational OLAP server, on multidimensional OLAP server, or on hybrid OLAP server.; In this study, we will look at the structure and functionality of the data warehousing. As part of the data warehouse architecture, OLAP server is used to change data ...
Thus, OLAP uses indexing algorithms for relational data and n-dimensional summarized data stored in cubes. Today database systems implement derived indexing algorithms based on well-known Tree, Bitmap and Hash indexing algorithms. This is because no indexing algorithm provides the best performance for...
A reliable performance improvement is achieved with the proposed IRIS (Information Retrieval using Indexing Scheme) in XML database to data warehouse, compared to an existing SDC technique for OLAP, in terms of search path length, search cost, Maintenance.Muthukumar R...
The need to process and analyze large data volumes, as well as to convey the information contained therein to decision makers naturally led to the development of OLAP systems. Similarly to SGBDs, OLAP systems must ensure optimum access to the storage environment. Although there are several ways ...

The present invention relates to the concept hierarchies in the space index method library of prefocus, and particularly, spatial database is related to providing a kind of method, and improving query processing for aggregated index SOLAP is the principle based on the layer in Spatial Data Wareh...
In general, various aspects provide methods, apparatuses, systems, computing devices, computing entities, and/or the like for performing data discovery on a target computing system.
To do this, you can index the snapshot of a query result in the BWA and make it available for SAP BusinessObjects Explorer. Example An example of this type of functionality that requires a full OLAP Engine is complex key figure conversions, for example of bottles and cans into liters. ...
By enabling users to pull in data from an online transaction processing (OLTP) database such as MySQL and PostgreSQL, Venkataramani said that users could now also benefit from the online analytical processing (OLAP) capabilities of Rockset's real-time indexing database. ...
Indexing requests are similar to write requests in a traditional database system. If our Elasticsearch workload is write-heavy, it's important to monitor and analyze how effectively we are able to update indices with new information.When new information is added to an index, or existing ...
