Abstract

A database processing system, which convert data in object oriented database to layout format suitable for every different compiler comprises of: (1) one schema register for analyze database structure definition file and writing structure of database structure definition file into database to from virtual schema; (2) one schema corrector for reading the virtual schema from database to memory, in the same time from programming language system getting dynamic data and saving to schema in memory; (3) one object fetcher used to get wanted object from database, and according to schema data value converting object data format to memory layout format suitable for programming language.

Description

A7 B7 30097: 8 V. Description of the invention (Background of the invention The feature of the individual-oriented database is to achieve the accessibility of the programming language company, that is, to make the application developed by the program developer's "second language: and access to individual orientation The programming language used by the database is consistent, and the data structure defined by application two can directly correspond to the outline in the database; since the object in memory is limited by the individual format formulated by the programming language (Object lay out), so that different programming language compilers, compilers developed by different manufacturers or different compilation options (C〇mpiler options) will affect the format of the individual layout in memory (layout f0rmat), when the data When the individual in the library is read into the memory, it is necessary to adjust the corresponding layout format with different compilers or compilation options; the conventional way or the program developer writes the program to overcome the problem & , Or the solution is not perfect enough to completely overcome the problem, it will increase the trouble of the developer of the program; the present invention provides an automatic conversion for the above problem The general individual connection system and method can effectively solve the above problems. One of the methods used in the prior art to describe the material combination method in the data-oriented database in the prior art is that S uses a compiler-translator to define the database structure. Compile it as a destination file, and then analyze all the data structures defined in the database structure definition target by the destination file analyzer, such as category (daw), structure (struct), etc., and then classify the above-mentioned analyzed category data, such as Static data such as attributes and some hidden dynamic (⑽Hme) data are obtained from the destination file and nested in the database to form an outline, and then the aforementioned category data is recorded in this paper standard sample (CNS—) Λ4 ^^ χ 297 public advantage) (please read the precautions on the back before filling in this page), νβ Ministry of Economic Affairs Central Standards Bureau employee consumer cooperation du printing sh included header file, and then write dynamic data into the category dynamic The relevant programs are shot, and finally the main program and the above files are compiled together to produce an execution building; the category dynamic data generated in this way is generated during the analysis process, and Write its content to the category dynamic related program files, so these dynamic data have become static data, and because the static dynamic data is compiled with the king program to generate an execution file, the generated and stored in the individual data after execution The individual data in the library can only be used by the program. Once the compilation options set in the original program are changed, the originally created individual database can no longer be used because the data in the original database is based on the original category The static dynamic data is generated, so the data cannot be used by other programs; moreover, compilers developed by different manufacturers have different layouts of individuals in memory, so the flares stored in the database The code is used for the execution files generated by different compilers; another method in the printing of Baizhi skills by the Employees Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economy is to store only individual data in the database, not program data. The program developer designs how to access the individual data in the database, that is, the program developer Design programs to store and manage individuals according to the characteristics of each category; therefore, at least two sets of programs must be designed to perform storage (st 〇re) and fetch (fetch) functions; this approach will increase the burden of programmers. The burden, especially when there are many categories, the added load will be even more amazing; in addition, when the demand changes, the original program structure will change, so the functions of the originally designed storage and retrieval functions will also change, more Two major shortcomings, that is not easy to maintain and not easy to expand, this paper ruler China National Redundant Vehicle (CNS) Λ4 specification (2 丨 0 x 297 / ^ · developed in order to solve the shortcomings of the universal individual connection system and the technical skills in this invention The above-mentioned learned knowledge comes out < novel and excellent from the data library to the record, ', corpse and all methods, can make # compiler or compile options.

The invention first reveals that: the general individual link module is used as different compilation options for different compilations and the automatic layout of different layout formats between individual data accessed from the database Conversion, so that the Zhao data in the database can be applied to various compilers or compilation options; the concept of the present invention is that only the virtual schema data is stored in the database by mistake. When the individual data in the database is to be read, Then the general individual connection system and the system environment consult to obtain the dynamic individual layout format data, and then fill in the virtual outline to form the actual outline, and then the individual data in the database are directly matched according to the outline data Conversion to the memory.

The program registrar includes an analyzer and a program generator. The functions of the analyzer and program generator are described as follows: Analyzer: read the database structure definition ❹ to obtain it All the data, including category name, inheritance (inheritance) and category name (parent class name), attribute (attribute) related data (including attribute name, attribute type, attribute size) or member function (membe Γ funct丨 〇n) Related information (including name, return value type, parameter name, type, number), provide a dynamic array to store inheritance relationship and parent category name, an attribute specification List to store all the relevant data of the attribute, and a member function specification array to store all the relevant data of the member function; then call the program registration function in the order of inheritance relationship to generate a virtual program, and the above data is transferred to the program In the parameters of the registration function, the database schema of the category is generated. The individual schema generator can be seen from Figure 2. After the analyzer 22 in the schema registry analyzes and processes the database structure and the target 20, a record will be generated. There is the name of the mesh in the database, and the relevant information of the mesh with the individual callback function of each program.
