Problems solved by technology

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

Abstract

The embodiment of the invention provides a persistence device and a method of a domain object model, and relates to the field of computers. The device performs persistence to extended properties of the domain object model, simplifies the operation during performing persistence to the extended properties of the domain object model, and improves the feasibility and the practicability. The method comprises the following steps: fixing column names and column values corresponding to the extended properties in a domain object according to a field object in an extended property container in extended model definition and class definition by obtaining the class definition and the extended model definition corresponding to the field object so as to generate extended column information, further fixing a storage strategy according to the type of an object database, and sending the storage strategy to the object database to store the storage strategy according to the storage strategy. The device is used for performing persistence to the extended properties 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 ...
