What is the data mart?

Data storage has become more important for modern companies, because the amount of data necessary to remain competitive and make informed decisions on the future of the company has increased and greater. The company's entire data warehouse often consists of a data collection of data, sets of data, which are usually focused on a specific department or area of ​​the company. Combined to the data warehouse Mart, this data helps to support the information system of the whole company. In some cases, MartS data is compiled from data from the main data warehouse. However, many companies approach the bottom -up data and instead create a total data warehouse compilation of data data of Mart into smaller systems and then combines it into a data warehouse throughout the company.

One important factor in the building data mart is usability. Since the Mart's data is usually aimed at providing information to a specific department for a specific purpose, the data must be easily accessible and processed.The company's information technology department or information systems specialists often focus on this area and ensure that there is an easy -to -use interface, so that employees, including high -level managers and other workers, have access to Mart and use them during their work.

The design of individual data MART depends on the specific needs of the company or individual department. Most of the data is organized in relational databases, while the database management system is implemented throughout the company to allow individual employees to easily access data, generate messages, or perform other necessary daily functions. Some companies require more complicated data processing, which forces us for multidimensional databases. Others use the functionality of the database that allows multidimensive data analysis while still using simpler and less expensive withYstem of relational databases.

For the most part, data warehouses are created by adding data as they come to the company's systems. Data updates are not so important for the overall view of the company's performance as the data that has been added and compiled for a longer period of time. Managers can use Mart data from the company's trends, sales formulas and the efficiency of individual departments and to predict future performance. At this level of strategic planning, data and data warehouses are invaluable to those who plan the future of the company.
