Abstract

The invention provides a data query method applied to a multi-level project system. The multi-stage project system comprises a first-level oil field database and at least two second-level oil field databases; data table structure data are stored in the first-level oil field database, and a data table set generated according to the data table structure data is stored in each second-level oil field database; the data storage formats of the data table sets in the second-level oil field databases are the same, and second-level oil field research and development data are recorded in the data tables in the data table sets; the method comprises the steps that the first-level oil field database sends a first data reading request generated according to data table structure data to the second-level oil field databases, wherein the first data reading request carries an identifier of a first target data table generated according to the data table structure data; the second-level oil field database searches a first target data table from a data table set of the second-level oil field database according to the identifier of the first target data table; and the second-level oil field database sends the first target data table to the first-level oil field database.

Description

technical field [0001] This application relates to database technology, in particular, to a data query method and system. Background technique [0002] With the rise of digital management models, digital management has also been integrated into the management of oilfield development projects in the field of oilfield development. [0003] In the prior art, for data management in oilfield development projects, a method of creating data tables in the project databases of each oilfield development project is adopted, and then the respective research and development data are filled in the data tables, and each project database Data is isolated to ensure data confidentiality between different oilfield development projects. However, after the number of oilfield development projects exceeds a certain number, the number of data tables is huge, the database is difficult to maintain and the cost of maintaining the database is huge. Contents of the invention [0004] In view of this...
