Abstract

The invention discloses a structure comparison method for databases. The structure comparison method comprises the steps of obtaining database information of a first database and a second database; correspondingly reading data dictionary information of the first database and the second database according to the database information; and performing comparison on the data dictionary information of the first database and the data dictionary information of the second database to obtain structural difference information of the first database and the second database. The invention also discloses a structure comparison apparatus for the databases. The invention provides the structure difference comparison method, which is simple to operate, for the databases; and the specific structural difference information between two databases can be acquired through comparison.

Description

technical field [0001] The invention relates to the field of databases, in particular to a database structure comparison method and device. Background technique [0002] A database is a warehouse that organizes, stores and manages data according to its data structure. The storage of any application data is inseparable from the database. For large-scale applications, multiple databases may be created to store different information in different categories. With the development, the released version of the application will be continuously upgraded (for example, from V1.0 version Upgrade to V1.1 version), and the upgrade between versions often involves changes in the structure of the database, which is reflected by writing database upgrade scripts. What developers and testers expect is that the function and database structure of the V1.1 version upgraded from V1.0 and the newly installed V1.1 version should be completely consistent. This requires comparing whether there is a d...
