Description

Technical Field

[0001] The present invention relates to the technical field of software development, and in particular to a method and device for quickly building a system based on metadata. Background Art

[0002] With the advancement of information construction in various industries, the information application and information degree of various departments and industries have gradually increased. Various industry systems such as material management (MRP), customer management (CRM), enterprise information management (ERP), etc. have been developed by professional software development engineers in various languages ​​and personal habits. These business systems are basically completed with thousands or even hundreds of thousands of codes, with a large development workload and complex systems. Once the development is completed, the system adjustment code workload is large, and it often occurs that one move affects the whole system; and there is a situation where the source of the system is not unified. If the underlying support business source of the system changes according to the business scenario, the business-related business system needs to be modified layer by layer starting from the data control layer. This requires a unified metadata management support and visual configuration management system support to solve such problems, so as to quickly liberate personnel labor and save costs. Based on this, this paper proposes a method for rapid construction of metadata-based systems.

[0003] Metadata is generally referred to as "data of data". Data governance based on metadata can help enterprises better manage data resources, clarify the relationship between data, achieve more accurate and efficient analysis and decision-making, connect source data, data warehouses, and data applications, and record the entire process from data generation to disappearance. Metadata can help data warehouse administrators and developers easily find their relationships, which can be used to guide their data management and system development and improve work efficiency.

[0004] With the development of information technology and the continuous maturity of computer technology, key business application systems and high-informatization systems continue to emerge, and different information systems meet the diverse needs of users. In order to meet the needs of users, developers need to update and maintain the software system in a timely manner. When new functions or new services need to be added, the traditional development model is to perform hard-coding development for each service. The so-called hard coding is to write data directly into the code for compilation and development. However, this development method is inefficient, modules cannot be reused, the system error rate is high, and system upgrades are prone to problems.

[0005] In order to solve the problems existing in the traditional method, such as low efficiency, non-reusable modules, high system error rate, and problems easily caused by system upgrades, the present invention proposes a method and device for quickly building a system based on metadata.

[0035] First, the access logic of the actual business database fields is independent of the basic database instance. Because the information maintenance reads the metadata that describes the business database, when the business database changes, such as the addition or deletion of fields or the increase of field width, it is only necessary to modify the parameter data in the metadata module and build a system to store the unique encoding information after the metadata is stored, without the need to recompile the code program. Secondly, the logical metadata structure is persistently stored and dynamically loaded, rather than being solidified in the program code. The visual interface configures the logical relationship between metadata and the business background, which facilitates the rapid adjustment of the system to adapt to the actual business needs of users.

[0036] The method for quickly building a system based on metadata includes the following steps:

[0046] (3) Visually configure the relationship between the target business and the corresponding business metadata.

[0047] In the third step, the metadata model is used to provide business logic operations and metadata assembly functions internally, and to provide translation functions in the process of converting standard business models and metadata externally.

[0048] In the third step, the business domain model is processed and converted, and the metadata is combined and organized according to logical rules based on the actual needs of the system business to form a logical business rule library related to the system business; at the same time, the standardization of the metadata model and the interface component technology are used to achieve the scalability of the specification and provide a public interpretation module.

[0049] In the fourth step, the relationship between the metadata and the business model output by the system, as well as the metadata in the actual business database are explained.

[0050] The device for quickly building a system based on metadata includes a metadata integration module, a system visualization configuration module, a system logic module and a metadata interpretation module;

[0051] The metadata integration module is used to connect to the metadata module in the data warehouse system and perform metadata conversion and adaptation to meet the needs of metadata module metadata management external service changes of different products; at the same time, the actual metadata system business interface is adjusted to reduce the complexity of adaptation, achieve standardized output of metadata, fault tolerance, and enhance the robustness and adaptability of the system;

[0052] The system visualization configuration module is responsible for constructing the system according to the standardized structure and business-related models within the system, combining the system business-related models with metadata, designing and describing the business domain data model, customizing the human-computer interaction interface of the business system software, and quickly building the application system;

[0053] The system logic module is responsible for performing business logic operations and analysis on the business logic model configured based on metadata, realizing the technical conversion between the system and the business model, and forming a logic business rule library related to the system business according to the actual needs of the system business, using the standardization of the metadata model and the interface component technology to achieve the scalability of the specification and provide a public interpretation module;

[0054] The metadata interpretation module is responsible for interpreting the business model generated by the system according to the metadata model formed in the system, generating a standard business database language, interacting with the actual business center library management system, and meeting the needs of related business systems.

[0055] Compared with the prior art, the method and device for quickly building a system based on metadata have the following characteristics:

[0056] First, using metadata to develop business systems can, on the one hand, decouple the logic between the system and the database and reduce the degree of coupling; on the other hand, metadata management functions can facilitate the supervision of the entire life cycle of data.

[0057] Second, it not only achieves effective supervision and integration of data, but also ensures high-quality and seamless flow of data in all links, reduces the creation of data islands, realizes the effective use of data, and effectively controls the only source of business data, ensuring the efficiency of data monitoring.

[0058] Third, developing application systems with the help of metadata thinking can make the entire system more adaptable to the needs of the current rapid information system development, and can ensure the scalability and reusability of the system, the uniformity of data after system upgrades, and the identity of data in the industry.
