Problems solved by technology

When there are more and more versions, the conversion relationship between data is as complicated as a spider web, and the workload of development and testing will increase exponentially, making system maintenance more and more difficult
[0008] 3) It will become impossible to use the data in the new version format on the old version software

Embodiment Construction

[0023] The present invention will be described in further detail below through specific embodiments and in conjunction with the accompanying drawings.

[0024] The implementation model diagram of this example is as follows figure 1 As shown, an object-oriented approach is used here. The system for implementing the solution includes software and hardware. The hardware platform includes a central processing unit and a memory connected to the central processing unit. The software includes an operating system and application programs. The memory is not limited to a specific storage medium. According to the technical solution of the present invention, each data element stored in the memory is composed of a type (ID) mark, a data length and a data body, so that the data has self-describing ability, describes its own data type, data length, etc., and also It is the Uelement in the model. Different applications may require different types of IDs, multiple types of IDs can be derived...

Abstract

The invention discloses a data processing method and storage method. The central processor at least marks a type marking field and a data length field to each data body to form a data element, the data element is stored in a storage; the type marking field describes the self-type of the data body, the data length field describes the length of the data element or / and the data body. The invention uses the realization mode of data self-description to fully separate the data and the design and cut off the coupling of the data and the design. The invention has a simple and high-efficient proposal, can store any kind of data, and can store any data elements with same type. In addition, the marking of the data can be freely extended and has no influence on the existed application. The data storage of the invention can realize one-time storage (namely can be compatible with each future upgrade).

Description

【Technical field】 [0001] The invention relates to a data processing method in a software system. 【Background technique】 [0002] Data storage in computer software systems, that is, data serialization, has a problem with the data file format, and this format is generally defined by the application system according to its own needs. However, with the upgrade of the application system, the quantity, type, length and order of the data to be stored will often change with the new requirements, resulting in the original defined data format not being able to meet the new requirements, and the result is sometimes even catastrophic of. Some systems do not consider compatibility at all, which is extremely irresponsible to old users; some systems are compatible in design, but many current solutions are not ideal. The fundamental reason is that the structure definition of data serialization has inherent defects. [0003] At present, there is a way of data storage, which partially solve...
