Rule based data normalization utilizing multi-key sorting

Methods and systems for efficient retrieval of neighboring measurement values in order to enable fast execution of rule-based error correction are disclosed. In one aspect, a method for data normalization using multi-key sorting is disclosed. In some embodiments, the method includes receiving, by a data organization engine, a set of uncorrected data including corresponding neighboring data. In various embodiments, the data organization engine organizes the uncorrected data by construction of a directed acyclic graph (DAG), where the DAG includes a plurality of nodes. In some embodiments, the data organization engine may traverse the plurality of nodes to retrieve the corresponding neighboring data. Upon retrieval of the neighboring data, a rule-based correction engine may correct the uncorrected data utilizing the retrieved corresponding neighboring data.
