Online analytical processing

CHAPTER 3 On-Line Analytical Processing Online Analytical Processing (OLAP) applications and tools are those that are designed to ask “complex queries of large multidimensional collections of data.” OLAP is used for data mining, as well as the discovery of undiscerned relationship between data items. Since not all transactional data is needed for trend analysis, the OLAP database doesn’t have to be as large as a data warehouse. With the use of Open Database Connectivity (ODBC), data can be imported

that an OLAP system which contains an information on server that allows quick access to data (atomic data and derived data) and facilities calculations. Because OLAP tools work with multidimensional data models, perform complex analytical queries, ad hoc and has a high processing speed, some scholars have suggested that they rather be called FASMI (Fast Analysis of Shared Multidimensional Information) . Thus, Nigel and Richard Creeth Pendle, from the idea that "18 or even 12 rules are too much "wanted

Introduction In Unit 3 you will review Chapter 6 - Productivity and Performance Management, and Chapter 7-Operational Metrics in health Care. Productivity and performance management is important for healthcare managers as this will ensure the healthcare organization or department is more cost-effective and efficient over time. This is done by reducing costs, eliminating waste, and ensuring efficiency in use of resources. The main focus of productivity management is the ratio of outputs to inputs

data warehouse optimized for processing and summarizing large amounts of data. Next this author will outline the difference database requirements for operational data for decision support data. Next this paper will describe three example in which databases could be used to support decision making in a large organizational environment. Lastly this author will describe three other examples in which data warehoused and data mining could be used to support data processing and trend analysis in a large

1. Security features comparison in Oracle and SAP HANA: Oracle claims that SAP HANA uses security functionality that is very basic and not advanced. But SAP HANA provides advanced security features without any cost. Oracle provides data availability and security as extra cost options. SAP HANA provides the following security features: SAP HANA Studio: Production System Warning, New kind of alert for Password Expiration, User names in Unicode, Encryption, audit logging, Authentication and Authorization

ETL Overview Within an enterprise there are various different applications and data sources which have to be integrated together to enable Data Warehouse to provide strategic information to support decision-making. On-line transaction processing (OLTP) and data warehouses cannot coexist efficiently in the same database environment since the OLTP databases maintain current data in great detail whereas data warehouses deal with lightly aggregated and historical data. Extraction, Transformation, and

Database refers to a collection of data that is specially organized for rapid search as well as retrieval by a computer (Strou, 2014). They are structured to facilitate storage, retrieval, and modification of data in conjunction with some data processing operations. Database management systems therefore assist in retrieving data or information from the database in response to queries made by the customers or

The text book Data Warehousing concepts, techniques, products and applications by C.S.R. Prabhu. Mainly, the text book gives the information about the data model, online analytical processing systems and tools, data warehouse architecture, data mining algorithms, organizational issues of the data warehouse, data warehouse segmentation, Application of data mining and data warehousing. Firstly, the book describes Data Warehouse is a system where it is used for reporting the data from the wide range

Assignment -3 Literature Review Conversion of the XML Schema to Data Warehouse Schema Introduction: eXtensible Markup Language is used mainly in most of the organizations for e-commerce and online applications. Indeed, XML has become the standard for representing, exchanging the data among the various applications on the internet. Moreover, XML schema is used for representing the XML document structure where XML data is associated with the XML schema. Furthermore, data warehouse provides tools
