What is a multidimensional database?
Multi -dimensional database is a database form that is structured to optimize online analytical processing (OLAP) and Data Warehouse. It can receive data from various relational databases and structure information into categories and sections that can be accessed in a number of different ways. Even people who have relatively little experience in working with a database often find that a multidimensional database or MDB requires only a short time. Rather, it creates a question, the user simply asks the daily verbiage. This approach is used with several online help tools associated with software programs such as text processing and spreadsheets, as well as with several more popular search engines that are currently used.
In terms of using multidimensional databases for internal business purposes, the main advantage is the ease of fast and brief data. For example, if the end user wanted to determine how many widget sales were generated during the thirdAbout the quarter of the last year in a given sales area, this data could be obtained from a multidimensional database with a simple question. By asking "how can widgets sell during the third quarter of 2007 in the southwestern territory?" The end user does not have to go through the assembly steps, field specification and content limitation in these fields to selected criteria. Using one simple question will complete the task.
The precise means of the wording will determine the question on several factors. One of the key elements is the sorting and type of data in a multidimensional database. Any question that contains the requirements that are not found in the database will not lead to a direct response, although many MDBS will respond with data based on available data. This means that if the end user asks, "How many widgets were sold last month in Virginia?" The database will be able to provide a focused response only if each sale contains the status of origin and the database has been configured to understand which month andThe year "last month" suggests. If not, a multidimensional database is likely to respond with some partial answers or ask for clarification.
