The present invention provides a kind of storage design method based on EF frames, belongs to Microsoft's .Net MVC frames and EF ORM framework technologies field, the invention mainly comprises following steps：S10：Abstract factory pattern builds program architecture；S11：Based on .Net MVC frames, view, controller, entity separation are carried out；S12：Physical model is built with EF, and is stored in a warehouse with T4 template establishments；S13：Business Logic and data access layer are abstracted and unify storage processing；S14：Support the expansible realization of disparate databases.The present invention realizes the scalability of .Net platform software Frame Designs, and the quick copy of software development can be achieved in this frame, quick to apply.
Description
Technical field
The present invention relates to Microsoft's .Net MVC frames and EF ORM framework technologies more particularly to a kind of storage based on EF frames to set
Meter method.
Background technology
With business development, agile development and platform compounds are increasingly tended in software development, and in most enterprises
Lack of standardization there are program coding, the program of facing project is even more that different people builds different codes, be easy to cause code confusion, can
The property read and maintainability are poor, once business variation or database table change modification backstage will be gone to realize manually, greatly
Reduce development efficiency and the scalability of software greatly.
The content of the invention
In order to solve the above technical problems, the present invention proposes a kind of storage design method based on EF frames.It realizes
The scalability and high efficiency of Software Coding, high cohesion, lower coupling and the modularization for realizing program become.
The technical scheme is that：
A kind of storage design method based on EF frames,
Mainly include herein below：
S10：Abstract factory pattern builds program architecture；
S11：Based on .Net MVC frames, view, controller, entity separation are realized；
S12：Physical model is built with EF, and is stored in a warehouse with T4 template establishments；
S13：Business Logic and data access layer are abstracted and unify storage processing；
S14：Support the expansible realization of disparate databases；
In S10, based on .Net MVC platforms, program architecture is built with abstract factory pattern.
Further,
In S11, software is realized in programming is respectively created procedure set by Views, controller and entity, each
Corresponding function is implemented separately.
Further,
In S12, physical layer realizes the direct-connected database of program, and the database information that upgrades in time accomplishes that ORM's is timely to EF models
Update creates T4 storages for the incidence relation synchronized update between tables of database, while by part entity.
Further,
In S13, Business Logic and data access layer upgrade in time according to EF data model informations and unify public method, with number
According to storehouse entity for unit realize More General Form under increase, deletion, modification, inquiry operation.
Further,
In S14, system supports the extension of disparate databases to realize, different data is realized by configuration file accreditation process collection
The operation in storehouse.
In S10 contents, solution is broadly divided into four solution file folders：Presentation layer, Business Logic, data
Access layer and common process layer；
Presentation layer again separates script page and controller, and the procedure set under a region is all divided for each type of service
To handle；Business Logic and data access layer place the interface of business processing and data access and Key Implementation code respectively；
Common process layer places public method, relies on injection and EF and relational data model.
It further includes
（1）Procedure set definition storage object is defined in the interface of Business Logic and data access layer；
（2）The additions and deletions that oneself correspondence model is implemented separately in each DB object change operation, and pass through and inherit public base class reality
The unified output of existing method, at the same each DB objects can document extend the method for oneself.
Description of the drawings
Fig. 1 is the flow diagram of the present invention.
Specific embodiment
More detailed elaboration is carried out to present disclosure below：
It is of the invention mainly to include herein below：
S10：Abstract factory pattern builds program architecture；
S11：Based on .Net MVC frames, view, controller, entity separation are realized；
S12：Physical model is built with EF, and is stored in a warehouse with T4 template establishments；
S13：Business Logic and data access layer are abstracted and unify storage processing；
S14：Support the expansible realization of disparate databases；
In S10 contents, further illustrate, it is necessary to perform following steps：
（1）Abstract factory pattern program architecture is built,；
（2）Solution is divided into four solution file folders：Presentation layer（UI presentation layers）, Business Logic, data access layer
With common process layer.
（3）Presentation layer again separates script page and controller, is all divided under a region for each type of service
Procedure set handle；Business Logic and data access layer place the interface of business processing and data access and key reality respectively
Modern code；Common process layer places public method, relies on injection and EF and relational data model etc..
In S11 contents, further illustrate：Based on MVC pattern, the separation of controller, view and model is realized, is controlled
Device is corresponded with Razor views, and model is according to practical business scene construction and is directly bound in view, realizes that deployment formula is compiled
Journey, by@model ModelName come Binding Model.
In S12, S13 contents, further illustrate, it is necessary to perform following steps：
（1）Procedure set definition storage object is defined in the interface of Business Logic and data access layer, such as Business Logic IBLL
It defines IBLLSession storage interfaces to correspond to, defining IDALSession storages in data access layer IDAL realizes object, simultaneously
T4 templates are defined by Partial classes, realize that binding EF models can upgrade in time the data messages of EF models, return to corresponding storehouse
Store up object.
public partial interface IDBSession{ int SaveChanges();} // public method
Public partial interface IDBSession { ... } //T4 template establishments change according to model
（2）The additions and deletions that oneself correspondence model is implemented separately in each DB object change operation, and pass through and inherit public base class reality
The unified output of existing method, at the same each DB objects can document extend the method for oneself, such as sign controller except exhibition
Show the individually extension login authentication of view needs, permission control then individually can correspond to login method by extended method.
In S14 contents, further illustrate, system supported on database realizing current mainstream oracle,
Sqlserver, mysql, by simply configuring operation, it can be achieved that the program interaction of disparate databases.Code revision is more square
Just, can also be realized by newly-increased procedure set extending database, such as newly-increased oracle is realized, can be increased ORADAL newly, be configured IDAL
Calling, scalability are higher.
By this method design it is a set of can quick copy OA Development of Framework frames.By this frame can quick copy it is similar
Type project substantially increases the development efficiency of OA systems, wherein
（1）UI layers of system.OAWEB is all front page layout displaying code layers, is all handled by Razor views.Helper layers
By Logic (service logic), Admin（System administration）, the several controller layer public methods of WorkFlow (workflow) are sealed
Dress realizes the convenience and uniformity of presentation layer calling.
（2）Business Logic.BLLA layers and IBLL layers are respectively service logic realization and service logic interface, realize business
The modularized processing of processing.
（3）Data access layer.DALMSSQL（Sqlserver databases）, DALMYSQL (mysql databases) realizes not
With database for the processing of data interaction.It is realized simultaneously by IDAL interface abstractions.
（4）Common layers.There are common process methods, rely on injection and model, facilitate global reference.
Unified coding frame of the present invention, after business changes, realize storage update and general service code from
Dynamic generation, can improve code efficiency, while improve the maintainability and scalability of software.
