-The primary attraction of an enterprise data warehouse is that all the data is constantly available for analyzing and planning purposes. The alternative is for a business to have different databases for each major branch or organizational division, leading to a complex schedule of data reporting to allow for higher level analytics and planning. An enterprise data warehouse imposes a standard treatment of data and can grow with a business’s needs by adding classifications as they emerge in the business model. Ideally, an enterprise data warehouse provides full access to all the data in an organization without compromising the security or integrity of that data.<ref>Explaining Enterprise Data Warehouse (EDW) [https://www.techopedia.com/definition/26204/enterprise-data-warehouse Techopedia]</ref>

-Over the course of the past few years, Enterprise Data Warehouse systems (EDW) have become one of the most important components of modern decision support systems. Their main benefit consists in bringing together data from different sources – not available in appropriate form in the operational systems, for instance because of missing historical data – in one central location and preparing them for analysis, or bringing together data from diverse sources that may have totally different formats. Added to this is a landscape that is increasing significantly in complexity and acting as the source of structured data (e.g. ERP systems), unstructured data (social networks) and even Big Data (e.g. sensor data from numerous events). Thanks to the use of an EDW system, the typical risks inherent in heterogeneous data warehousing that most companies are faced with, i.e. losing track, increasing data redundancy and long decision-making paths, can be avoided effectively. All relevant partial data from the most important data sources along your company’s entire value chain are brought together simultaneously in a way that facilitates rapid and purposeful decision-making at all company levels. Various types of information, for instance on suppliers, products, production, stock levels, partners, customers, staff and sales, are all combined in the data warehouse system to provide a holistic view.<ref>Understanding Enterprise Data Warehouse (EDW) [https://www.cubeserv.com/enterprise-data-warehouse-en.html CubeServe]</ref>

 In order to give a clear picture of an Enterprise Data Warehouse and how it differs from an ordinary data warehouses, the following five attributes may being considered. This is not really exclusive they bring people closer to a focused meaning of the Enterprise Data Warehouse from among the many interpretations of the term. These attributes mainly pertain to the overall philosophy as well as the underlying infrastructure of an Enterprise Data Warehouse.
-*The first attribute of an Enterprise Data Warehouse is that it should have a single version of truth and that entire goal of the warehouse’s design is to come up with a definitive representation of the organization’s business data as well as the corresponding rules. Given the number and variety of systems and silos of company data that exist within any business organization, many business warehouses may not qualify as an Enterprise Data Warehouse.

 *The third attribute is that an Enterprise Data Warehouse should have a normalized design. This may be an arguable attribute as both normalized and de-normalized databases have their own advantages for a data warehouse. In fact, may data warehouse designers have used denormalized models such as star or snowflake schemas for implementing data marts. But many also go for normalized databases for an Enterprise Data Warehouse in the consideration of flexibility first and performance second.
-*The fourth attribute is that an Enterprise Data Warehouse should be implemented as a Mission-Critical Environment. The entire underlying infrastructure should be able to handle any unforeseen critical conditions because failure in the data warehouse means stoppage of the business operation and loss of income and revenue. An Enterprise Data Warehouse should have high availability features such as online parameter or database structural changes, business continuance such as failover and disaster recovery features and security features.
