Fecha de publicación: 12/09/2019 Fuente: Wipo "BigData" The present disclosure discloses methods and systems for managing data in a database in accordance with a data model, henceforth referred to as a "timeline store" (202) or "timeline model". The method includes mapping (402) each data reference of one or more data references with a data value of a block of data in a data store (204). Then, each key reference of one or more key references is mapped (404) with at least one pair of a time reference and the data reference in a timeline store (202), the time reference determines a point in time at which the key reference is assigned the pair of the time reference and the data reference. Thereafter, the data model is queried (406) to retrieve a set of key references mapped to data references based on a specific ranges of keys and time or time intervals. Finally, the data model is queried (408) to retrieve the raw data bytes associated/mapped with/to any desired data reference.
