Abstract

The invention provides an object-oriented database system based on a category fiber bundle model and a construction method thereof. The system comprises a category fiber bundle model processor, a category construction definition language, a category construction preprocessor and the like. The method comprises the following steps of designing and constructing a category fiber bundle model at the first step, and then designing and realizing a general framework of a category fiber bundle database system on this basis to realize a complete support of a database system for the category fiber bundle model. One uniform mathematic model is designed and made, so that the disadvantages that the conventional relational database is difficult to directly access and manage object-oriented data structures, such as a multi-level data structure and multidimensional relations, and on the other hand, the modern object-oriented database lacks formal database definition and operating language and is difficult to guarantee integrity, consistency and correctness of the database after object addition, upgrading and deletion owing to lack of a mathematic model basis are simultaneously effectively solved.

Description

technical field [0001] The invention relates to the technical field of databases, in particular to an object-oriented database system based on a category fiber bundle model and a construction method thereof. Background technique [0002] A database is "a warehouse that organizes, stores and manages data according to the data structure". In the daily work of economic management, it is often necessary to put some relevant data into such a "warehouse" and perform corresponding processing according to the needs of management. For example, the personnel department of an enterprise or institution often needs to store the basic information of its employees (employee number, name, age, gender, place of origin, salary, resume, etc.) in a table, and this table can be regarded as a database . With this "data warehouse", we can check the basic situation of a certain employee at any time as needed, and we can also check the number of employees whose salary is within a certain range, et...
