The data warehousing contains the combinations of technology, methodologies, tools and techniques , user management system and data manipulation systems. But according to the dictionary definition warehousing is to gather up the data from the different and various kind or resources and interrelated the complied information collected from the different types of data resources. May leading organization has their separate warehouse for the collection and maintenance of data.
Data warehousing currently hold important position into the market concerning the organization it is done for. It captures huge area in the present economy. the most famous people into data are housing foundation and origination are the Ralph Kimball and Bill Inmon .they are collectively known as the pioneer of the data warehousing. Before the arrival of the data warehousing there was no concept for the data storage and synchronization according to the need of the data. Many reach papers were published in the year 2002 .it was the same year when it was found. But the core concept was evolved in 1990 by the Bill.
Features of the Data warehousing
There are very unique and significant properties of the data warehousing .some of the major one s are as follows.
Decision making support
Warehousing provide great support in the entire decision making process because its core components involves all the major plans, methodologies and technique that will be implemented to achieve the goal. Conceptualized and complied form of data is nicely helpful in taking quick and accurate decisions.
Another important characteristic of the warehousing is that it s subject oriented. the data is gathered from the different resources each resource has different background and applicational secularities .this helps in smoothing the companies regular operations because grounded knowledge about all required is available with the help of warehousing.
Another important and fundamental characteristic of the warehouse is the integration of the data. The data is gathered form the different resources and then merged after compiling it to the single database. Which is dynamically and diversely applicable.
Al the data that is stored at the warehouses are identified through the specific time period according to the need of the data.
Non volatile form f data.
Before the arrival of warehousing properly it was known the secondary storage is the best way to save the information but warehousing also supported the integration, cohesiveness and multi dimensional application of the data. Warehousing is one of the finest way to preserve the entire knowledge for the effective utilization in he future. The data stored in the warehouses remain stable and safe. This makes data more reliable.
Data can be stored in the large volumes according to the sizing of the warehouse. it depends on the organization what kind and amount of data they required to store or the future use.
Accurate and grounded
Another property of the data stored at the warehouses is that the data is accurate and grounded containing all the practically possible theories and techniques. We can say that essence of the related field is stored at the warehousing. Number of technologies is involved in preserving the data which make it discrete, effective and multi dimensional.
Warehousing was officially introduced in 2002 and it is becoming famous day by day. at present there are many organizations especially larger one having own warehouses .for preserving different types of data .the advanced engineers and programmer area working to set online warehousing systems to make the access of data more efficient and quicker. Warehousing is one of the most effective techniques for saving the large and dynamic amount of data.
