First-Half Index Base For Querying Data Cube

International audienceGiven a relational fact table R, we call a base of data cubes on R a structure that allows to query the data cubes with any aggregate function. This work presents a compact base of data cubes, called the first-half index base, with its implementation, and the method for querying the data cubes using this base. Through experiments on real datasets, we show how the first-half index base resolves efficiently the main data cube issues, i.e., the storage space and the query response time
