However, the current mainstream data persistence framework can only persist for the general domain object model, and for the persistence of the extended attribute of the domain object model, it is necessary to force the domain software platform to adjust itself to adapt to the differentiated requirements of different business software systems. Causes the reverse dependence of the platform on the business software system, and when a field software platform supports multiple business software systems, it causes conflicts and flooding of extended attributes
In this way, when the business software system persists the extended attributes of the domain object model, the operation is complicated and the feasibility and practicability are low

Embodiments of the present invention provide a domain object model persistence device and method, which relate to the computer field. A method for persisting the extended attributes of the domain object model is provided, which simplifies the operation of persisting the extended attributes of the domain object model, and improves the feasibility and practicability. The method is: by obtaining the domain object and the class definition and extended model definition corresponding to the domain object, according to the extended model definition and the extended attribute container in the class definition, determine the column name and column value corresponding to each extended attribute in the domain object, and generate the extended column Information; further according to the type of the target database, determine the storage strategy, and combine the storage strategy to send the extended column information to the target database for storage. The embodiments of the present invention are used to persist the extended attributes of the domain object model.
Description
technical field [0001] The invention relates to the computer field, in particular to a persistent device and method for a domain object model. Background technique [0002] Data persistence, that is, saving data (such as objects in memory) to storage devices that can be stored permanently (such as disks). The main application is to store data in memory in databases or disk files, XML data files, etc.; The domain object model, that is, the model of domain objects, can be regarded as a conceptual model of a system, which is used to define the various entities in the system and the relationship between them, record the key concepts and vocabulary in a system, and define their respective attributes. [0003] At present, domain software platforms often need to provide general domain capability support for different business software systems in similar domains. Taking the personnel management platform as a domain software platform as an example, it can be used to support library ...
