Abstract: A method of storing and accessing data in a database system is disclosed. The database system comprises at least one data source. The database system is associated with at least one adapted data structure, which defines the physical data storage structures (e.g. row storage, columnar storage) in which the data are stored. Data is allocated from the at least one data source to the at least one adapted data structure in correlation with a database query received, i.e. based on the data access patterns (e.g. queries) the physical data storage structures in which the data managed by the database system are to be stored are dynamically determined.
