Abstract
The invention relates to a building method for a dynamic database, comprising the following operation steps: firstly, a classification list, an attribute list, a hierarchical relationship list, an object list and an attribute value list are generated; secondly, storage objects are identified; thirdly, the storage objects are abstracted into classes; class names and class attributes are determined; the class names are filled in the classification list; class attribute names are filled in the attribute list; fourthly, hierarchical relationships between the classes are determined; hierarchical relationship data of the classes are filled in the hierarchical relationship list; fifthly, the classes are instantiated; the abstracted class names and the abstracted class attribute names are respectively endowed with corresponding values which are then stored in the object list and the attribute value list; sixthly, hierarchical relationships between class examples are determined, and corresponding hierarchical relationship values are stored in the hierarchical relationship list; seventhly, a target database is generated. The method dynamically generates the database in virtue of an object-oriented method and all products are allowed to have consistent data description forms, thereby flexibility and compatibility of an application system are improved, and development cycle and cost of a database system are greatly reduced.
Description
Technical field
The present invention relates to a kind of dynamic data base construction method, specifically, is a kind of database construction method based on the SQL SERVER of Microsoft software.
Background technology
Traditional relation data base construction method is generally undertaken by the E-R model.The structure person is at first by each storage object of identification, and after excavating its mutual relationship, set up the corresponding E-R model of describing these storage objects and mutual relationship thereof, be converted to relational model then, finish the structure work of entire database by creating corresponding tables of data again.The method of this structure database is accurately clear, is present the most frequently used a kind of database construction method.But, the shortcoming of this method is to lack the support to dynamic modeling, constructed database structure is fixed, can only reflect static, pre-determined storage object and mutual relationship thereof, must be thereby cause at the different different database structures of database application design, and when the storage object of Database Systems or when describing attribute and changing, just have to could adapt to this variation to the structure redesign (database restructuring) of this database.Yet along with the continuous expansion of the infosystem application in modern times, the demand of dynamic modeling has proposed challenge to traditional relation data base construction method.Many specific areas all require Database Systems can manage the storage object of continuous variation, describe the management object and the attribute information of dynamic change.
Summary of the invention
The objective of the invention is to problem, a kind of dynamic data base construction method is provided at the prior art existence.Utilize this method, can in the Database Systems operational process, dynamically make up database, thereby improve service efficiency, dirigibility and the compatibility of Database Systems, reduce the cycle and the expense of information management system exploitation according to practical application request.
The core of the dynamic data base construction method that the present invention proposes is the OO thought of utilization, realizes dynamically setting up database and Dynamic Maintenance database structure.Operation steps is as follows:
1) generates classification table, attribute list, hierarchical relationship table, Object table and attribute value table;
2) identification storage object;
3) with storage object abstract be class, determine the attribute of class name and class, insert class name to the classification table, insert the attribute-name of class to attribute list;
4) determine hierarchical relationship between the class, in the hierarchical relationship table, insert the hierarchical relationship data of class;
5) instantiation class is given corresponding value respectively with the attribute-name of abstract class name that comes out and class, deposits Object table and attribute value table in;
6) determine hierarchical relationship between the class example, in the hierarchical relationship table, deposit corresponding hierarchical relationship value in;
7) generate target database
Making up in the method for database according to this method, described classification table includes 5 fields, and described attribute list has 4 fields, and described hierarchical relationship table has 5 fields, and described Object table has 4 fields, and described attribute value table has 5 fields.
Making up in the method for database according to this method, described tables of data can also comprise log sheet, subscriber's meter and authority list etc.
Making up according to this method in the method for database, the attribute of described class is various features of describing storage object.
Making up according to this method in the method for database, described class is the set that the attribute that extracts from storage object is formed, perhaps the community set that is provided with according to user's needs.
Making up according to this method in the method for database, described tables of data and database leave in the computer-internal storer or external disk of operation application system.
Implement database construction method provided by the present invention, a kind of method for the treatment of storage object with OO visual angle can either be provided, thereby more easily the storage object in the real world is converted to the data model that computing machine can be represented, again can by class generalization of dynamic perfromance description, object identifier, class and the polymerization of specialization, class with decompose isotype, thereby the method for operation parameterization is extracted the common trait of these objects uniformly to these object modelings.After the product object being carried out consistent modeling, just be formed naturally unified Database Systems, promptly all products all have identical structure, according to system requirements these product objects are connected and form tables of data and target database.Simultaneously, the consistance of product data is handled and is also made system user can revise product freely according to the needs of self, the contact of product and the data structure of product.Improve the dirigibility and the practicality of application system, significantly reduced the repeated workload that is applied to, reduced the cycle and the expense of Database Systems exploitations.
Description of drawings
Fig. 1 is that the dynamic data base of one embodiment of the invention makes up the implementation step synoptic diagram.
Embodiment
Below in conjunction with embodiment and accompanying drawing the present invention is further explained explanation.
Embodiment one: the vehicle management database, and referring to Fig. 1.
1) in the Enterprise of SQL SERVER Manager, creates classification table, attribute list, hierarchical relationship table, Object table and attribute value table; 2) according to regulatory requirement, identify storage object: automobile, truck, engine, tire etc.; 3) with these storage objects abstract be class, and determine the attribute of corresponding class name and class.As automotive-type, truck class etc., the attribute of truck: price, dead weight capacity, model and color etc.Then, each class name is inserted the classification table as an entry; Each attribute-name is inserted attribute list as an entry; 4) hierarchical relationship between the establishment class is divided into truck, car, motorbus etc. such as automobile, and truck is made up of engine, tire etc.Then these hierarchical relationship data are inserted in the hierarchical relationship table; 5) carry out the class instantiation according to the concrete object that will manage, be instantiated as east wind DF6, liberation JF6, and deposit east wind DF6 and the value of liberating JF6 and price, dead weight capacity, model and color in Object table and attribute value table respectively as the truck that will be abstract comes out; 6) determine hierarchical relationship between the class example, deposit in the corresponding hierarchical relationship table as the component relationship of east wind DF6 and the general TY6 of engine; 7) promptly generate target database after the input of all data.
