In particular, data such as positions data, trade data, tax lot data can maintained in one or more data tables and subsequently reconciled, updated, and reported using agnostic data storage and access mechanisms that allow for up-to-date and accurate data monitoring, gathering, manipulation, and reporting.

Abstract: Methods and systems of agnostic data storage are provided. The agnostic data storage systems and methods store data records of various data types from different data sources. The method stores IDs and data elements of data records in different data tables. IDs of data records are stored in a first table, and data elements of data records are stored in a second table. Data entries of the second table are linked to an entry in the first table. The second table stores data element name, data element value, and data element data type respectively.
