Evaluation Of User Requirement Analysis Of Data Warehouse Design

An active data warehousing, or ADW, is a data warehouse implementation that supports near-time or near-real-time decision making. It is featured by event-driven actions that are triggered by a continuous stream of queries that are generated by people or applications regarding an organization or company against a broad, deep granular set of enterprise data. Continental uses active data warehousing to keep track of their company’s daily progress and performance. Continental’s management team holds an operations meeting every morning to discuss how their

One of the main functions of any business is to be able to use data to leverage a strategic competitive advantage. The use of relational databases is a necessity for contemporary organizations; however, data warehousing has become a strategic priority due to the enormous amounts of data that must be analyzed along with the varying sources from which data comes. Company gathers data by using Web analytics and operational systems, we must design a solution overview that incorporates data warehousing.

This is the scenario where Key Performance Indicators (KPIs) comes into the picture. These are the factors which defines the business productivity and efficiency. These KPI will help business to tackle the critical business problems so stakeholder can determine the strengths and weaknesses of business and influence the future decisions. A data warehouse generates huge amount of data that can be productively operated. In today’s world, data warehousing is an uncompromising business with demanding customers. So defining the KPI’s is an important task which will display exactly what the customer

We will discuss in this paper the data warehousing and the online processing of data. We will describe the best ways to manage the data and the difficulties that you could face. Also we will talk about how can we solve or reduce these difficulties.

A data warehouse (DW) can be acknowledged as one of the most complex information system modules available and it is a system that periodically retrieves and consolidates data from the sources into a dimensional or normalized data store. It is an integrated, subject-oriented, nonvolatile and a time-variant collection of data in support of management’s decisions (Inmon, 1993).

A data warehouse is a place where data is stored for archival purpose, analysis purpose.

Data warehouse is aggregation of subject-oriented, integrated databases, which is designed to confirm DSS support. Now days these repository has become a focal point for DSS in organisation. These data repository used for online analytical Processing (OLAP), data mining and support queries. Decisions which are pending from a long time get resolved by analysing data warehouses. Another benefit of data warehouse is it improves the productivity by redesigning business process and work. It is challenging and technical undertaking because data comes from different sources and systems. There are some other organisational issues like sponsorship maintenance, scope avoidance and political issues. Because of these reasons data warehouse project get

This database provides general reports for. E.g. Daily Sales report by product or by customer or by route. These reports are helpful— particularly for real-time reporting —but they don’t allow in-depth analysis. The possibilities for reporting and analysis are endless. When it comes to analyzing data, a static list is insufficient. There’s an intrinsic need for aggregating, summarizing, and drilling down into the data. A data warehouse enables you to perform many types of analysis:

3. DESIGN – This phase frames the design of how the proposed system should work.

The increasing importance of broadband speeds and online services have made it necessary for businesses to demand real-time access to their databases. Organizations are always striving to stay ahead of the curve by applying the most up to date technology and development approaches so they can fully benefit from having 24/7 access to their content. The initial step in the development process normally involves carrying out a plan which will serve as a guide in the implementation of the functional specifications.
