Automatic construction method for data cascading operation of heterogeneous system based on relational database

Abstract

The invention provides an automatic construction method for a data cascading operation of a heterogeneous system based on a relational database. A server can supply a data service to a heterogeneous system client in the manner of a message interface and supply the data cascading operation of a relation list in the manner of configuration item in the interface. The method comprises the following steps: acquiring business metadata through a connecting relational database; generating a source code with a seven-layer structure by a code generator, wherein the seven-layer structure includes a display layer, an entity layer, a control layer, an analysis layer, a treatment layer, a packaging layer and a lasting layer; and generating the document for updating entity and related entity storage, inquiring details of entity and related entity, inquiring the entity and related entity list, deleting the entity and deleting five interfaces in batches by the entity by the code generator, thereby supplying the data service to the front-end display development of various clients.

Description

technical field [0001] The invention relates to a method for automatically constructing heterogeneous system data cascading operations based on a relational database. Background technique [0002] Automatic construction refers to the automatic generation of products that meet business requirements through pre-customized templates according to different business metadata, which greatly saves the manufacturing time and labor costs of enterprise products, and has a huge effect of improving efficiency in many application fields. Functions, such as 3D printing, automobile manufacturing and other industries, automatic construction is also an indispensable helper in the development of software systems such as e-commerce, Internet finance, and enterprise informatization. Programmers can perform secondary business logic based on automatically generated source code files. Second development, so that more energy can be spent on business logic and user interface interaction, greatly imp...

Problems solved by technology

This solution can map out the metadata XML configuration file according to the relational database, and then apply the macro to the code template to generate the MVC target code to improve the development speed, but this method needs to manually map the metadata XML configuration file or use a reverse tool to map, The steps are a bit redundant, it is not convenient to directly connect to the database to read metadata, and the front and back ends do not use the interface definition method, so they cannot provide data services for other heterogeneous system clients
