A local cube, also known as a cube, is a multidimensional data structure that organizes data hierarchically in the form of multiple dimensions. It is predominantly used in the field of data warehousing and business intelligence to facilitate fast and efficient data analysis and reporting.
A local cube represents a subset of data extracted from a larger data warehouse or database and is designed to provide users with specific and relevant information for analysis. It contains pre-aggregated data that is organized into dimensions, measures, and hierarchies. The dimensions represent different characteristics or attributes of the data, such as time, geography, product, or customer. The measures, on the other hand, are the numeric values that are being analyzed, such as sales revenue or quantity sold.
The key advantage of a local cube is its ability to provide quick response times for complex queries and analytical operations. This is achieved by pre-calculating and summarizing the data, enabling users to access and manipulate the information in an intuitive and efficient manner. Additionally, local cubes support advanced features like drill-down, drill-up, pivoting, slicing, and dicing, allowing users to analyze data from different perspectives and levels of granularity.
In summary, a local cube is a multidimensional data structure that provides a subset of pre-aggregated data for analysis. It offers fast and flexible querying capabilities, enabling users to gain valuable insights from their data efficiently.
The etymology of the phrase "local cube" can be understood by examining the origins of its individual words.
1. Local: The word "local" originated from the Late Latin word "localis", which means "pertaining to a place". It later evolved in Middle English as "localle" and eventually became "local" in modern English. The term refers to something that is specific to or associated with a particular place or area.
2. Cube: The word "cube" comes from the Old French word "cube", derived from the Latin word "cubus" or "kybos", which was borrowed from the Greek word "kubos". The concept of a cube as a three-dimensional shape with six equal square faces has been present since ancient times in mathematics and geometry.
