Problems solved by technology

[0002] Because there are different concepts in real life, in the current modeling field, there is a lack of unified understanding standards when mapping these concepts to data models, resulting in different abstract standards and constraint concepts, and existing systems cannot manage different constraints concepts and abstract standards, so it is difficult to achieve effective interconnection of data within the system

Embodiment Construction

[0024] The implementation of the present invention will be described in detail below in conjunction with the drawings and examples.

[0025] The visual modeling platform based on the unified constraints of standard data elements (hereinafter referred to as "modeling platform") of the present invention is a database model design platform designed with standard data elements and unified constraints that can manage unified data sources of large-scale application systems . The types of models that can be parsed by the modeling platform include conceptual models and physical models, and data models can be loaded by reading model files, reading standard data element files, and downloading standard data elements from the public model library. After the data model is loaded into the modeling platform, users can modify the data model and manage model files through visual editing. The user needs to realize the instantiation of the data model after saving all the modifications to the da...

Abstract

Provided is a visual modeling platform based on unified constraint of normal data elements. The platform comprises a data exchange layer for the modeling platform to transmit data, a model layer undergoing unified constraint and application of the normal data elements, an operation control layer for executing model construction, model maintenance, model storage, model loading and model instantiation and a view layer for visually displaying model elements in the data elements. The platform can generate a data model based on a target database management system, can establish an application model for an application program and can perform unified management of various data sources of a large system. The platform can support various hardware environments, is compatible with various operating systems and supports database design tools of various target database management systems.

Description

technical field [0001] The invention belongs to the fields of databases and data modeling, and in particular relates to a visual modeling platform based on uniform constraints of standard data elements, which can realize database design and unified management of system data sources. Background technique [0002] Because there are different concepts in real life, in the current modeling field, there is a lack of unified understanding standards when mapping these concepts to data models, resulting in different abstract standards and constraint concepts, and existing systems cannot manage different constraints Concepts and abstract standards, so it is difficult to achieve effective interconnection of data within the system. Especially when a system needs to correspond to different database management systems and apply different database designs, the huge data source is more difficult to manage. [0003] On the other hand, due to the diversity of data elements, software develop...
