1. Introduction
CNUX .Net
Providers Web Service Plug-in for SQL Server is an extended .Net
web state-management framework based on Microsoft® ASP.Net 2.0 specifications
and guidelines. It is a complete
framework consisting of Membership Provider, Role Provider, Site Map Provider,
Session State Provider, Profile Provider, Web Event Provider and Web Parts
Personalization Provider. CNUX .Net
Providers Web Service Plug-in is ideal for SOA and secured n-tier
implementation. 2. What’s in CNUX .Net Providers Web
Service Plug-in?
CNUX .Net
Providers Web Service Plug-in includes many exciting features in addition to
the standard Microsoft® ASP.Net 2.0 providers framework. Refer to
the following table for information about the latest features and enhancements.
Table/Diagram 1. Feature Summary 3. How CNUX .Net Providers Web
Service Plug-in Works
The web
service providers are split into two parts: Service Consumers and Service
Providers. The
Service Consumers library integrates seamlessly with the front end web application
typically located in the DMZ, while the Service Providers are located within
your internal network and communicates with the database backend. Diagrams 2
& 3 below are two commonly used network configurations when DMZ is used to
host web applications:
Table/Diagram 2. Secured N-tier network model using DMZ and a three legged firewall
Table/Diagram 3. Secured N-tier network model using DMZ and dual firewalls The
following two sections explain how the CNUX .Net Providers Service Consumers
and Service Providers work in conjunction with the Microsoft® ASP.Net
services. 3.1
Service Consumers on Web Server
In the top
layer of the Web Server - Service Consumers portion (see diagram 4) are UI
controls such as Login, CreateUserWizard and other .Net application codes that
call Microsoft® ASP.Net services. In the
second layer lie the base classes for Microsoft® ASP.Net services. These services do not communicate with the
Service Providers directly. Instead all
operations are done via the CNUX.ProvidersServiceConsumer Concrete Classes. If any
controls need to be customized and are calling methods are not already
available within the Microsoft® ASP.Net services framework, the
CNUX.ProvidersServiceConsumer concrete classes can be inherited and
extended/overridden in the extended classes layer. In general this approach can be used for
moving custom data between Service Consumers and Service Providers, or
performing functionalities that are not within the scope of Microsoft® ASP.Net
services. All
CNUX.ProvidersServiceConsumer classes and custom extended classes communicate
with their respective Service Providers ASMX objects via SOAP messages. 3.2
Service Providers on Application Server
In the top
layer of the Application Server - Service Providers portion (see diagram 4) are
ASMX objects that communicate with the Service Consumers. These Service Providers in turn call
Microsoft® ASP.Net services in the second layer. These services do not store and manage data in
the data storage directly. Instead all
operations are done via the CNUX providers as Concrete Classes. If any
methods of the concrete classes need to be further customized, the concrete
classes can be inherited and extended/overridden in the extended classes layer.
Table/Diagram 4. CNUX .Net Providers Web Service Plug-in Model 4. Features
4.1. Compatibility
All
CNUX .Net Providers are built for the Microsoft® ASP.Net Framework 2.0, 3.0 and 3.5,
and 100% compliant and compatible with the information and requirements
documented in the Microsoft® ASP.Net 2.0 model.
There is
no behavioural difference when compared to the out-of-the box .Net Providers
for SQL Server provided by Microsoft®.
Other
providers are not applicable.
Please
note that Microsoft® SharePoint® 2007 server does not support customization of
providers other than Membership and Role. 4.2. Programmability
CNUX .Net
Providers offers concrete classes that can be easily incorporated into any web
projects using the Microsoft® Visual Studio® environment by placing the CNUX
.Net Providers module in your Microsoft® Visual Studio® project’s bin directory and modify a couple of
settings in the web.config file.
All CNUX
.Net Providers classes are derived from the abstract Microsoft® ASP.Net
providers classes and therefore can be replaced or extended with any
implementation you require via inheritance should any further customization be
required. 4.3.
Provider Types
The following
tables illustrate all the services and the corresponding CNUX .Net Providers:
Table/Diagram 5. CNUX .Net Providers table
Table/Diagram 6. CNUX .Net Service Consumers table 4.4.
100% thread safe
All CNUX
.Net Providers conform to the Thread Safety requirements as documented in http://msdn2.microsoft.com/en-us/library/aa479030.aspx. Without
thread safety the code can produce data corruption and hard to reproduce
sporadic errors due to the following summarized nature of Microsoft® ASP.Net
providers architecture: §
Microsoft®
ASP.Net providers are instanced once and shared among requests §
Each
request is processed on a different thread drawn from a thread pool §
A
provider can be accessed by multiple threads concurrently 4.5.
Transaction control
Transactions
are applied to all singleton/multiple method calls and database updates to
guarantee atomicity according to suggestions as documented in http://msdn2.microsoft.com/en-us/library/aa479030.aspx. 4.6.
Exceptions - Error trapping
All CNUX
.Net Providers trap all errors and throw exceptions according to guidelines as
documented in http://msdn2.microsoft.com/en-us/library/aa479030.aspx.
4.7.
Support all Microsoft® documented ASP Roles and
Views
CNUX .Net
Providers support all the ASP Roles as follows:

Shared
Shared This feature is particularly useful for environments
where a single sign-on application is used for general user authentication and
multiple web applications can be invoked or spawned within it once a user’s
identity is verified. From there on
information can be passed to and from the sign-on application and the spawned
applications. 4.10.
Database Failover/Database Clustering
All CNUX .Net Providers can be deployed to Database Failover/Database Clustering environments. 5. Sample Codes
