Embodiment Construction

[0053] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0054] The present invention carries out structural layering to SDO, respectively establishes service data object models of different levels: domain object model, data object model, physical table model, data object-physical table mapping model, and makes the models of these different levels separate from each other . In this way, during business development, data objects can be generated from basic domain objects according to business needs, thereby reducing the workload of business development and improving development efficiency.

[0055] With reference to the flow process of a preferred embodiment of the method for setting up the connectionless data programming model of the present invention shown in Fig. 2, this embodiment comprises the...

Abstract

A method for setting up data programming model free of connections includes laminating service-data object, setting up data programming model for each layer separately according to laminated service-data object. The device used for realizing said method and a data access-service manner are also disclosed.

Description

technical field [0001] The invention relates to data access technology, in particular to a method, device and application for establishing a connectionless data programming model. Background technique [0002] Currently, almost all information processing systems target specific types of data sources. In the information processing system, the access technologies for specific types of data sources mainly include: relational database access technology through JDBC (Java Database Programming Standard), or XML file access technology through XPath (XML path language). [0003] With the extension of enterprise business, the enterprise information system is constantly expanding, or develop new functions on the original system, or integrate the original independent subsystems to realize enterprise information sharing. This means that enterprise information systems are always faced with the challenge of dealing with heterogeneous data sources. The so-called heterogeneous data source...
