Embodiment Construction

[0013] The mapping system from a C language structure to a relational database table in the present invention includes a mapping code generation engine from a C language structure to a relational database table, a mapping extensible markup language description module from a C language structure to a relational database table, and a The mapping code from the C language structure to the relational database table uses the module.

[0014] The code generation engine for mapping the C language structure to the relational database table includes a relational database management system adapter, an extensible markup language analysis engine, and a C language code generation engine. Although relational databases have a unified structured query language, the C language access interfaces for different relational database management systems are different, and relational database management system adapters provide corresponding optimized access interfaces for different database management s...

Abstract

The invention relates to the field of embedded technology, in particular to a system and a method for mapping a C language structure to a relation database table. The invention discloses a system for mapping the C language structure to the relation database table, which simplifies the conversion from the C language structure to the relation database table. The system for mapping the C language structure to the relation database table comprises a mapping code generation engine module from the C language structure to the relation database table, a mapping extendable mark language describing module from the C language structure to the relation database table and a use module of a mapping code from the C language structure to the relation database table. The invention also provides a method for mapping the C language structure to the relation database table. The invention simplifies the cockamamie data management, shields the influence of the change of a lower-layer database on the upper-layer application simultaneously and improves the transferability of the application.

Description

technical field [0001] The invention relates to the field of embedded technology, in particular to a mapping system and a mapping method from a C language structure to a relational database table. Background technique [0002] At present, the performance of embedded devices is constantly improving, embedded applications are becoming more and more abundant, the data operations involved are becoming more and more complex, and the requirements for data management are greatly improved than before. Embedded relational databases are the development trend Very quickly, embedded databases have been used in the current embedded development. On the other hand, the C language is easy to transplant, close to the bottom layer, and has high performance. It has always been the main language for embedded development. However, in the C language, the data is stored in the C language structure, while in the relational database, it is stored in a table, and the operations on the data are fixed...
