Abstract: A fusion query method and a multi-model database (MMDB) framework are provided, to add a capability of extending a foreign engine in a relational database engine and manage metadata of the foreign extensible engine by using a user table. This minimizes intrusion to the relational database engine, and implements dynamic loading and unloading of the foreign engine during runtime. Therefore, a maintenance interface and uniform data access to a multi-model database such as a relational database, a graph database, or a time series database are provided for a user, so that learning and use costs of operation and maintenance personnel and application development personnel are reduced, and security of data use is improved.

Abstract: A time series data injection method is provided, including: receiving time series data, where the time series data includes at least one parameter identifying a data source that generates the time series data, an indicator indicating at least one attribute of the data source, and a timestamp indicating a time point when the indicator is generated; storing a first parameter group in a row storage format, where the first parameter group includes the at least one parameter identifying the data source that generates the time series data; and storing a second parameter group in a columnar storage format, where the second parameter group includes the indicator indicating the at least one attribute of the data source and the timestamp. In the method, the time series data is injected in a hybrid row-column storage manner.
