  • Dynamic selection of source table for DB rollup aggregation and query rewrite based on model driven definitions and cardinality estimates
    Patent number: 10282446
    Abstract: A method for optimizing data access in a data warehouse having a model driven architecture is provided. A data model for storing time series measurement data representing a plurality of dimensions and measurements is received. The data model includes one or more aggregation tables. A query having one or more predicates is received from a user. The one or more predicates are analyzed to determine whether the received query can be optimized using the existing aggregation tables. The received query is optimized using the aggregation tables, in response to determining that such query optimization is possible.
