System for realizing object continuous service and method thereof

Abstract

This invention relates to subject sustaining service and discloses one system and method to realize the simple service, which comprises the following steps: using functional calculus to sum up database operation example common frame and defining the database operation module; defining detail property in servo module and registering basic module; realizing detail database requirement language structure and middle property and database form according to the transferring of the operation module.

Description

technical field [0001] The invention relates to object persistence service, in particular to the realization of object persistence service. Background technique [0002] With the advent of the information age, the application of the network has penetrated into every aspect of people's lives. The sharp increase in the amount of data on the network puts forward higher and higher requirements for the management of network data. [0003] Currently, the development of network management software mostly adopts a three-tier architecture of client / server mode, including a client, a server, and a relational database (Relational DataBase, RDB for short). On the one hand, the server is connected to the client through the communication platform; on the other hand, the RDB is manipulated through the database middleware. The task model faced by the server is an object-oriented model, which accepts standard C++ objects as the input of the task, and returns the corresponding standard C++ ...

AI Technical Summary

Problems solved by technology

[0005] First, the code redundancy is greatly increased, and a considerable proportion of the code is used for data model conversion, which greatly increases the workload of development

[0006] Second, when developing a task, in addition to understanding the transaction logic of the task, the developer must not only master its task model, but also master the storage model of the relational database, as well as the model conversion between them, which greatly increases development difficulty

[0007] Third, in the current development mode, data model conversion and database manipulation are completely explicit. DBI functions are full of hard-coded relational database manipulation. The relational schema of relational databases (including table names and column names) Tightly coupled with the code logic, making the later maintenance of the system extremely difficult

[0011] In practical application, the above-mentioned solution has the following problems: for the existing technical solution 1, the actual amount of code writing has not been reduced, the phenomenon of code redundancy still exists, and the situation that the system is difficult to maintain and expand has not been improved

[0014] The reason why there are problems in the actual application of the prior art solution 2 is that the solution requires the establishment of ODL and the implementation of an ODL compiler for translating the Interface Definition Language (Interface Definition Language, referred to as "IDL") into corresponding C++ codes and Relational Database Script, an object manager built on top of relational databases

The writing of these codes is very huge in terms of workload, and cannot be accepted by most small and medium-sized software companies.
