Recently, research about the indexing technologies of data warehousing has been proposed to help efficient online analytical processing (OLAP). In the past decades, some novel indexing technologies of data ware
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...
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 system for an in-memory row storage architecture can be provided. In some implementations, the system performs operations comprising adding a data row to an in-memory row store at
To realize different kinds of spatial OLAP operations and provide spatial decision support more flexibly, a spatial data warehouse framework is studied, in which spatial data cube cooperates with spatial index structure. 为了实现各类空间联机分析,提供更加全面灵活的空间决策支持,提出了一个空间数据立方体与...
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 ...

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 ...
Similarly, the inherent complexity of the queries addressed to On-Line Analytical Processing (OLAP) databases mandates the need for an efficient indexing methodology. Choosing the ideal index structure for a data warehouse based on the form of the data in the repository is very critical in the ...
