  • Smart direct access
    Patent number: 11568067
    Abstract: A computer system including in-memory cache storage may be used to store collections of metadata that provide a semantic layer for a query of a data source. The computer system may provide multiple users access to the metadata collection, using different security policies for the users, without duplicating the metadata collection in the in-memory storage. For instance, the computer system may retrieve the metadata collection and provide the first user access to the metadata collection based on a first security policy of the first user. The computer system may then provide a second user access to the metadata collection based on a second security policy of the second user, without the metadata collection being duplicated in the in-memory cache storage.

  • Hybrid online analytical processing (OLAP) and relational query processing
    Patent number: 11556525
    Abstract: In some embodiments, a method receives a connection to a data source. The method analyzes metadata of the data source to determine a first type of metadata for a first type of database access and a second type of metadata for a second type of database access. The first type of metadata and the second type of metadata are combined into a data structure. Then, the method stores the data structure where the data structure is used to analyze a query to determine which of the first type of database access and the second type of database access to use for the query.
