Abstract
A database system includes an original data source storing pieces of original data and a cache source storing pieces of cached data, each associated with an accuracy value. A method of processing queries in the system includes: for each randomly selected client query, retrieving a first piece of cached data matching the query, and retrieving a first piece of original data matching the query; for non-selected client queries, retrieving a second piece of cached data matching the query; evaluating the accuracy value of the second piece of cached data; if the accuracy value is below a given threshold, retrieving a second piece of original data matching the query, and updating the second piece of cached data by the second piece of original data; and adapting a probabilistic model based on the first piece of cached data and the first piece of original data using a machine learning algorithm.
