Bone metastasis happens in people who have cancer that forms in another part of the body. Cancer cells from that area break away and travel through the bloodstream and lymphatic system. When the cancer spreads to distant body organs, this is called metastasis.
Teradata. A multidimensional database (MDB) is a type of database that is optimized for data warehouse and online analytical processing (OLAP) applications. Multidimensional databases are frequently created using input from existing relational database s.pproaches to how data is stored and the user interface vary. Conceptually, a multidimensional database uses the idea of a data cube to represent the dimensions of data available to a user.
Databases configured for OLAP use a multidimensional data model, allowing for complex analytical and ad hoc queries with a rapid execution time. They borrow aspects of navigational databases, hierarchical databases and relational databases.ultidimensional structure is defined as a variation of the relational model that uses multidimensional structures to organize data and express the relationships between data. The structure is broken into cubes and the cubes are able to store and access data within the confines of each cube.
