What Is a Data Cube? 365 Data Science
WebJan 22, 2024 · An attribute containing calculated members can't be a parent-child attribute. The calculated members of user hierarchies aren't exposed in Power BI. You can instead connect to a cube that contains calculated members on user hierarchies. In computer programming contexts, a data cube (or datacube) is a multi-dimensional ("n-D") array of values. Typically, the term data cube is applied in contexts where these arrays are massively larger than the hosting computer's main memory; examples include multi-terabyte/petabyte data … See more Multi-dimensional arrays have long been familiar in programming languages. Fortran offers arbitrarily-indexed 1-D arrays and arrays of arrays, which allows the construction of higher-dimensional arrays, up to 15 dimensions. See more Many high-level computer languages treat data cubes and other large arrays as single entities distinct from their contents. These languages, … See more • Array DBMS • rasdaman • OLAP cube • Australian Geoscience Data Cube See more In 2024, the ISO SQL database language was extended with data cube functionality as "SQL -- Part 15: Multi-dimensional arrays (SQL/MDA)".
