Described are a system, method, and computer program product for accelerated database queries using aggregation definitions. The method includes receiving a first set of database queries and parsing each query to produce a plurality of query parameters. The method also includes determining a plurality of frequencies based on a frequency of each query parameter occurring in the first set of database queries. The method further includes generating a plurality of aggregation definitions based on the plurality of query parameters and the plurality of frequencies. The method further includes determining a candidate set of aggregation definitions from the plurality of aggregation definitions, based on a number of queries that would be at least partially satisfied by each aggregation definition of the plurality of aggregation definitions. The method further includes generating an aggregated dataset based on the candidate set of aggregation definitions and performing a database query using the aggregated dataset.

A method, system and computer program product is disclosed for performing data ingestion. A request is received for data ingestion. Based on the request received, a client resource information with a server resource information is compared. After the comparing of client resource information with server resource information, location for formatting of data during data ingestion is determined. Further, in response to the determination of location, formatting of the data is performed at the determined location.

Data ingestion process

A computer-implemented method includes identifying a mobile phone. The method includes identifying one or more input devices. The one or more input devices are associated with the mobile phone. The method includes collecting behavior information from the input devices. The method includes applying machine learning to the behavior information to yield a schedule.
