  • Publication number: 20230244681
    Abstract: An HTAP database based on a consensus algorithm is provided. The HTAP database comprises a row-column hybrid store distributed storage system and a distributed SQL execution engine. The row-column hybrid store distributed storage system includes a row store bank and a column store bank, where data stored in the column store bank is a subset of data stored by the row store. The distributed SQL execution engine is used to receive transactional and/or analytical requests sent by a client, and to access the row store bank while executing the transactional requests and access the column store bank while executing the analytical requests, thus ensuring the isolation of the transactional and analytical requests to achieve load isolation, ensuring freshness and consistency of the data, and also ensuring high scalability and availability of the system.

  • Patent number: 7847547
    Abstract: A method of determining a concentration level of a compound in a mixture is provided. A plurality of compounds are identified in the mixture based on intensity peaks identified from NMR data generated from the mixture. A compound is selected from the identified plurality of compounds for a concentration determination. A concentration equation associated with the selected compound is determined. A first peak associated with the selected compound is selected from the NMR data. The selected first peak does not overlap with a peak associated with another compound of the identified plurality of compounds. An intensity value associated with the selected first peak is determined. A concentration of the selected compound in the mixture is calculated using the determined concentration equation and the determined intensity value.
