Abstract
The invention discloses a C#-based quick data access layer implementation method, wherein a three-layer structure is involved and is provided with a User model layer, a User Controller service layer and a User Provider data layer. The C#-based quick data access layer implementation method comprises the following steps of: (1) defining one or two attribute classes; (2) analyzing the model layer; (3) defining a base data layer Base Provider attract class and practical classes of various data types; (4) defining a data access layer factory Provider Manager; and (5) switching and combining between different data access modes. In the mode provided by the invention, a large amount of development workload and unit testing workload is saved undoubtedly for development personnel; and when the structure of the model changes, other functions are not required to be modified yet.
Description
Technical field
The present invention relates to a kind of quick data access layer implementation method based on C#.
Background technology
Passed through nearest 20 years, OOP technology (object-oriented (00) programming technologies) has got into a stable developing stage in the application of industrial circle.The programmer has admitted the characteristic of speech sounds as type (classes), an object (objects), method (methods) now.C# is a kind of typical object oriented language, and a kind of development scheme commonly used just is based on OO three-tier architecture now.Three-tier architecture on the ordinary meaning is used whole service exactly and is divided into: presentation layer (UI), Business Logic (BLL), data access layer (DAL).The purpose of distinguishing level is promptly for the thought of " high cohesion, low coupling ".Data access layer direct control database wherein is to operations such as different model (Model) data increase, delete, change, look into.
Summary of the invention
Technical matters to be solved by this invention provides a kind of workload of mass development and workload of unit testing of saving, and changes when model structure, does not also need the quick data access layer implementation method based on C# of related other functions of modification.
The present invention realizes through following technical scheme: a kind of quick data access layer implementation method based on C#; Comprise three-layer structure; Said three-layer structure has User model layer, UserController operation layer and UserProvider data Layer, and its step is following:
1) defines one or two Attribute class;
2) model layer is resolved;
3) definition basic data layer BaseProvider abstract class, and the utility classes of various data types;
4) ProviderManager of data access layer factory;
5) switching between the different pieces of information access module and combination.
Further, said Attribute class comprises Table Properties class and field attribute.
Further, said Table Properties comprises table name, major key, connection name and default sort attribute.
Further, said field attribute comprises field type and field length attribute.
The beneficial effect of the quick data access layer implementation method based on C# of the present invention is: reduce developer's workload, aspect data access layer, reach the effect of quick exploitation.Concrete having a few as follows: 1) minimizing can significantly improve work efficiency in the overlapping development of data access layer; 2) easily realize disparate databases, the parallel and switching of different pieces of information access type (such as Oracle and Ms sql); 3) fast run-up table; 4) discern the corresponding data access classes automatically for needs expanded data function.
Embodiment
A kind of quick data access layer implementation method based on C# comprises three-layer structure, and said three-layer structure has User model layer, UserController operation layer and UserProvider data Layer, and its step is following: 1) define one or two Attribute class; 2) model layer is resolved; 3) definition basic data layer BaseProvider abstract class, and the utility classes of various data types; 4) ProviderManager of data access layer factory; 5) switching between the different pieces of information access module and combination.
Wherein, said Attribute class comprises Table Properties class and field attribute.Said Table Properties comprises table name, major key, connection name and default sort attribute.Said field attribute comprises field type (major key and common) and field length attribute.
Embodiment 1
1) calls certain model data access layer instance;
2) judge whether the existing buffer memory that waits for quietly;
3) existingly wait for buffer memory quietly and return instance.
Embodiment 2
1) calls certain model data access layer instance;
2) judge whether the existing buffer memory that waits for quietly;
3) do not wait for buffer memory quietly and get into the data access class that judges whether correspondence;
4) have corresponding data access class get into instantiation such;
5) this instance is put into static cache;
6) return instance.
Embodiment 3
1) calls certain model data access layer instance;
2) judge whether the existing buffer memory that waits for quietly;
3) do not wait for buffer memory quietly and get into the data access class that judges whether correspondence;
4) do not have corresponding data access class get into instantiation such;
5) the connected mode generation according to this model changes corresponding instance;
6) this instance is put into static cache;
7) return instance.

Appendix UserController operation layer
Appendix UserProvider data Layer
The beneficial effect of the quick data access layer implementation method based on C# of the present invention is: reduce developer's workload, aspect data access layer, reach the effect of quick exploitation.Concrete having a few as follows: 1) minimizing can significantly improve work efficiency in the overlapping development of data access layer; 2) easily realize disparate databases, the parallel and switching of different pieces of information access type (such as Oracle and Ms sql); 3) fast run-up table; 4) discern the corresponding data access classes automatically for needs expanded data function.
The above is merely embodiment of the present invention, but protection scope of the present invention is not limited thereto, and any variation or replacement of expecting without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
