In subject area: Computer Science A data cube is defined as a lattice of cuboids representing multidimensional data, where each cuboid aggregates measures for different group-bys. It allows for online analytical processing by precomputing and storing data for efficient query processing. ...
Data warehouses combine a mix of technologies and components that largely help in the strategic use of information received. The process revolves around the electronic storage of a large amount of information obtained by businesses and intended for queries and analysis rather than transaction processing...
the concept has stayed pretty simple. The idea has been to use Hadoop as a place that data of all types could be stored in greater detail than ever before, at an affordable cost, and then used to power the existing data warehouse ecosystem and also perform new types of analytics. ...
A data cube is a multi-dimensional ("n-D") sequence of values in computer programming contexts. The term data cube is usually used in contexts where these arrays are massively bigger than the main memory of the hosting computer; examples include multi-terabyte/petabyte data warehouses and ...
