    Abstract: In an embodiment, a method comprises storing metadata that maps a domain model to data stored in a plurality of data stores, each data store being associated with a particular query language, the domain model describing the data and relationships between the data. The method comprises receiving a request for data stored in a first data store of, the request being in a request query language based on the domain model. The method comprises generating an abstract syntax tree indicating a field selection, an entity path, and a condition based on the request; generating a structure model comprising one or more aggregation levels for one or more entities; and generating annotations comprising query language aliases for portions of the request and correlating the portions of the request with the metadata. The method comprises generating queries in a first query language associated with the first data store based on the annotations; and sending the queries to the first data store.

    Abstract: A computing system and platform uses various types of data stores to allow efficient querying of, and accelerated access to, extremely large data sets. One such data store is a dimension store that combines key-value and columnar stores, access to which is provided by several selectable mechanisms chosen based the nature of the data of interest. These include bitmap-based access, us of an optimized columnar data format, and access via namespace identifiers. A compressed, optimized page data format is provided for storing and analyzing large fact-based data. The complex dimension store is used to provide complex relationships and interpretation of the fact-based data, enabling high-performance advanced queries, with bitmap indexes passed between the two stores. Dimension data is stored in an encrypted manner throughout the system, and can be exchanged among parties in a secure manner.

    Abstract: A method of transforming requests into queries on a data store is disclosed. The method comprises receiving, by a processor, a request for data stored in a data store, the request being in a request query language based on a domain model, the request including a first part specifying a navigation path of one or more joins and one or more aggregations, the request including a second part specifying details of the one or more joins and aggregations; mapping, by the processor, entities specified in the request to a plurality of tables and a plurality of fields in the data store using metadata associated with the domain model; creating table aliases based on the plurality of tables or the one or more joins; creating field aliases based on the plurality of fields or the one or more aggregations; assembling the table aliases and the field aliases into one or more queries associated with the data store; sending the one or more queries to the data store.
