Research paper on data warehousing

The evolution of data and database migration large scale projects such as the merging of multiple sites, green it initiatives, virtualization projects, database server consolidation and the cycle of technology refreshes are common in the database world. The raw increase in computing power, and the ability to push numbers and move large amounts of data in reasonable amounts of time have enhanced the abilities and sizes of databases.... The distinct systems comprising the actual data is most repeatedly accomplished as well as run by a number of employees.

Data warehousing research papers

Various researches have been carried out that focused on representations that are processed in batch mode and visualize each value with almost equal dependability. Using its features, you can store and manage data with all the advantages of a relational structure plus pl/sql, an engine that provides you with the ability to store and execute program units. The second section of this paper will concentrate on the difference between primary and secondary storage.

Instead of getting queries on standard or user-specified relationships, data mining goes a step farther by finding meaningful relationships in data.... Introduction big data is a relatively recent concept in the marketing world that describes the process of analyzing massive data sets to uncover trends. Data warehousing is a new term in my department where we use the network appliance (netapps) netfiler storage devices/units.

There are numerous business intelligence techniques adopted by organizations to bring about meaningful purpose of their raw data/information.... A data warehouse is a database-centric system of decision support technologies used to consolidate business data from many disparate sources for use in reporting and analysis (data warehouse). This metadata does not contain any of the database's data, but only information about the structure, storage and use of the database's data.

This paper will look at the definition of big data and how it is being used, why the current dbms is unable to handle big data efficiently, what hardware and software solutions are being tested, and what challenges the researchers are facing. Data security is known as shielding an organized body of related information, also called as database security.

The prior application processed steps sequentially one processor at a time thus not using the multiprocessor capabilities of its machine to process the huge quantity of data. The information stored in the data warehouse can be easily and efficiently accessed for making effective decisions. Data mining is a powerful tool that is designed to gather large sets of data at incredible speed and analyze them.

Data breach can be considered as an incident which involves the unlawful and unauthorized viewing, access or retrieval of sensitive, confidential or protected data. The term data warehouse was first coined by bill inmon, who has been commonly recognized as the “father of data warehousing” and is the lead proponent of the normalized or sometimes referred to as the top-down, appro... Introduction:  in today’s world, data spill is such an event that the highly unlikely or impossible happens.

Seale, 2004) there are both practical and methodological ad-vantages for researchers to use data that has been collected by others in order to pursue new research.... Data may be abstracted from primary sources and collected for unique reporting requirements, such as specialized registries or claims transactions.... The impact of green data centers on energy efficiency   green data center potentiates energy efficiency a data center is a facility/equipment used in housing computer systems and other computer related components, including storage systems and telecommunications (glanz, 2012).

Accuracy of data input there are various methods for entering data into a computer system. Apart from a complex architecture, involving data sources, the data staging area, operational data stores, the global data warehouse, the client data marts, etc. With big data, there is access to data that was always available, but it was not consumable by the end user....

A database, a dbms, and the application programs that use the data in the database make up a database environment.... In this chapter the researcher is presenting the empirical data gathered from the interviews which combines the qualitative and quantitative information. While permission may have been received with each bit of information, which may have appeared harmless to divulge, there are issues regarding the data's ownership -- its sharability in us or globally, its combination with other data, its accuracy, its security, and its overall end use...
