Description

technical field [0001] The present application relates to the field of data storage, in particular to a method and device for acquiring database types. Background technique [0002] The data warehouse is used to centrally store individual database tables of a company or database tables of multiple companies. The database tables in the data warehouse include two database types: business tables and dictionary tables. For example, a company's attendance sheet is a business table. Suppose the attendance sheet includes three columns. The first column is used to store the employee's name, the second column is used to store the department, and the third column is used to store the punch time. [0003] In order to reduce the capacity of the attendance sheet, each employee's name corresponds to a number, and each department also corresponds to a number, so that the number corresponding to each employee's name is actually stored in the first column, and the second column stores the n...
