However, when used as a caching layer, in-memory databases reduce the burden on the primary database during request peaks. All of these are highly educated and experienced in the field of DBMS. Perhaps its main disadvantage is its very complexity. Below are the advantages and disadvantages: Advantages Multi-Dimensional Data Models are workable on complex systems and applications, unlike simple one-dimensional database systems. Multidimensional databases are mainly used for analytics and data mining applications. On the contrary, MOLAP has all possible combinations of data already stored in a multidimensional array. explanation style is very easy and precise manner that make easy to understandable . Improving the reliability of an application may seem counterintuitive due to the volatility of data stored in RAM. In this video, we focus on the concept of multi-dimensional database. For many organizations, it can be too easy to exceed the use of their services only to realize the problem during billing.
