MVC Architecture

MVC architecture  is basically designed to separate the business logic and application data from the presentation data to manage easily.
MVC stands for L Model – View – Controller

1).  Model: The model object knows about all the data that need to be displayed. It is model who is aware about all the operations that can be applied to transform that object. It only represents the data of an application. The model represents enterprise data and the business rules that govern access to and updates of this data. Model is not aware about the presentation data and how that data will be displayed to the browser.

2). View : The view represents the presentation of the application. The view object refers to the model. It uses the query methods of the model to obtain the contents and renders it. The view is not dependent on the application logic. It remains same if there is any modification in the business logic. In other words, we can say that it is the responsibility of the of the view’s to maintain the consistency in its presentation when the model changes.

3). Controller:  Whenever the user sends a request for something then it always go through the controller. The controller is responsible for intercepting the requests from view and passes it to the model for the appropriate action. After the action has been taken on the data, the controller is responsible for directing the appropriate view to the user. The views and the controllers work very closely together.

Advantages of using the MVC Architecture.

1. Code developed using MVC is resuable
2. When the problems recurs, there is no need to invent a new solution, we just have to follow the pattern and adapt it as necessary.
3. By using the MVC design pattern our application becomes more expressive.
4. Expaning of an application is very easy as business logic is seperated from UI.
5. Tomorrow if you need to switch the database from, say, SQL to Oracle you dont need to change the whole application, only the Model layer will be changed.

E-Commerce, A name started few years back and now ruling the world. Most of the companies started their E-Commerce portals to sell products online to increase their sales and some are even only online portals they don’t have off line stores and they sell some one else’s products.

1. A neat and clean website design

Your website UI design must be very clear and soothing that users visit again and again, atleast to review the design.

2. Avoid Ads:

if you want to show some Ads go for internal Ads, Like Ad of one of your product which is going to appear on other page

3. Easy to find Products:

Put a Search box, so that users can easily find the products on website, People don’t remember SKUs so make the search keyword enabled, better to go for Full Text Search.

4.  Better Searched Results Page:

The search results page should be interactive enough to display the maximum products and at the same time the page should not be cluttered enough that irritates the customer to find the required product.

5. Put Drill Down on Searched Results:

The successful websites like Amazon, E-Bay, CNET etc have the Drill Downs impemented on the searched results. Suppose user entered the keyword “Laptop” in the search box, Now it will display the list of all the laptops in the searched results but the true E-Commerce leader will display the searched results as the Groups of Laptops. Grouping by Brand, Grouping By common paratmeters like screen size, RAM, Processor, Next Generation Processors, Price Slabs (500$ – 800$, 1000$ to 1200$) etc so that user’s can easily idetify the product that they required.

6. Product Details Page:

Your  product details page is very important for the user, as its going to behave like a Sales Man, Display the product with Multiple pictures, one picture on the screen of medium size and show some icons of the images below the main image and let the user to view the bigger images. Give all the four views of a product to user for his satisfaction.

Dont write very long descriptions, describe important points and give a summary too.

7. Product Variants:

Display variants of products on Product Detail Pages. When you enter a shop and check a laptop the sales person will also show you the different models of that laptop or different skins available for that so that you can have options to buy. similarily this page is your sales man.

8. Shopping Cart:

Make an interactive shopping cart, easy to operate where the quantity of the prodcuts can be altered.

Move a SharePoint Content Database / Deploy sharepoint site

our Official website (http://www.zonixsoft.com)

You have two initial options, doing a backup and restore within MOSS to move the data, or doing it at the SQL/STSADM level.  I prefer the latter, as it isn’t nearly as inclined to fail and leaves you with more flexibility.

1) Find the content Database

These are listed under Central Admin->Application Management->Site Collection List

2) Backup the content database

You could alternatively detach it, and copy it.  Just doing a backup in SQL Server 2005 Management studio is easier.

3) Restore content database to new server

Copy the BAK file to new server.  Create an empty DB in Management Studio, restore from backup, you may need to change an option in the “options” tab of the restore dialog to get it to work.  (Overwrite db).

4) Create Web App on new Server

Central Admin->Application Management->Create or extend Web App->Create New Web App.

5) Associate restored DB with new Web App

Central Admin->Application Management->

SharePoint Web Application Management->Content Databases->

Remove Content Database from your new web app.

Now use STSADM to add restored DB to this web app

c:program filescommon filesmicrosoft sharedweb server extentions12bin on new server is where you can find the STSADM.

run this command from there.

stsadm -o addcontentdb -url http://yourwebapp:port -databasename yourcontentdb -databaseserver yoursqlserver

6) Run ISSRESET from command prompt.

Web Parts

Visit: http://www.zonixsoft.com

This article discuss about the Web Parts, new feature introduced in ASP.NET 2.0. Web Parts are objects which the end user can open, close or move from one zone of the page to another. Web Parts allows for personalization of page content. They allows users to move or hide the Web Parts and add new Web Parts changing the page layout.

Web Parts Modes

Modes are very powerful in that they enable user to edit Web Parts, delete the Web Parts or customize Web Parts.

m    a) Normal mode: End user cannot edit or move sections of page. Simple Browser mode.

m    b) Edit Mode: End user can edit Web Parts on the page including Web Parts title, setting custom properties.

m    c) Design Mode: End user can rearrange the order of the page Web Parts in a WebPartZone.

m    d) Catalog Mode: End user enjoys the choice to add new Web Parts in any WebPartZone on the page.

Web Part Manager:-

Web Part Manager control is server control that completely manages the state of the zones . This control doesn’t have any visual interface,. You can have only one WebPartManager for each page that works with Portal Framework.

Web Part Zone:-

You can declare each web zone in one of two ways. You can use the <asp:WebPartZone> element directly in the code, or you can create the zones within the table by dragging and dropping Web Part Zone controls onto the design surface. You can place anything in zones including HTML elements, web server controls, user controls and custom controls. Any thing placed into WebPartZone can be treated as Web Part. Useful attributes of WebPartZone include LayoutOrientation attribute which controls the display of items either horizontally or vertically.

Catalog Zone:-(To add new Web Part)—-Catalog Mode

The ASP.NET 2.0 Portal Framework enables an end user to add Web Parts, but you must also provide the end user with a list of items he can add. It is designed to allow for categorization of the items that can be placed on the page. Catalog Zone is also a template control. The Catalog Zone control contains a title and checkbox list of items that can be selected. The Catalog Zone control also includes a drop down list of all available Web Part Zones on the page. From here, you can place the selected Web Parts into one of the Web Part Zones available from the list.

CatalogZone Contains CatalogPart controls like DeclarativeCatalogPart, PageCatalogPart, and ImportCatalogPart.

·       PageCatalogPart: Provides a page catalog of Web Part controls that a user has closed on a Web Parts page, and that the user can add back to the page.

·       DeclarativeCatalogPart: Enables developers to add a catalog of Web Part controls to a Web page so that users can choose whether to add them to a page.

·       ImportCatalogPart: Imports Web Parts controls, so that the control can be added to a web page with pre-assigned settings.

Changing mode of page:-

You can use either WebPartManager class directly or through the use of WebPartManager server control, you can change the mode of page. Changing the mode allows the user to make changes to pages they are working with. All the changes (mode changes) are recorded to ASPNETDB.MDF database associated with app_data directory created exclusively for Web Parts. Using WebPartManager object, you can add new Web Parts to the page. It also enables end user to drag and drop elements around the page.

Moving Web Parts—Design Mode

We can also move WebParts from one zone to another zone. This is possible through Design mode. To move any control just hover mouse over title of the control and you can see crosshair mouse symbol. Click the left mouse button and hold the Web Part and drag it to any WebPartZone. While dragging, the control it becomes transparent and drops the control in WebPartZone.

Editing the Web Parts—Editing Mode

Another Web Part mode that allows end-user to edit the Web Parts is Edit mode. This mode enables users to modify the settings related to behavior, appearance and layout for a particular Web Part on the page. When the user change the mode to edit you can see Appearance Editor/Layout Editor appear in the EditorZone. Appearance section allows users to change title and how the title of Web Part appears. Layout section enables user to change the order in which Web Parts appears in a zone or move Web Parts from one zone to another. Behavior section enables site editors to change dynamics of how end user can modify Web Parts.

Connection Between Webparts:-

Web parts are also capable of exchanging data between them, using web part connections. Using connections, you can have one web part provide one or more property values that can be used by other web parts on the page.

A WebPart Connection is a mechanism for sharing or transferring data from one Web Part (called the provider) to another Web Part (called the consumer). it is the ability to expose an interface to a WebPart (Provider) that another WebPart (Consumer) can connect to and use it

·       Connection types

Provider :-
– Control that provides data information
– Implements a provider connection point
– Defines a call back that returns an instance of the interface
– One provider connection point can connect to any number of consumer connection points of the same type

Consumer :-
– Control that gets data
– Implements a consumer connection point
– Defines a call back that gets an instance of the interface return by provider
– One consumer connection point can connect to only one provider connection points of the same type

·       Connection To establish a communication channel between provider and consumer WebParts so that they can exchange required information as defined in communication contract. A connection is establish between two connection points.The ConnectionPoint base class defines an object that is associated with a consumer or provider and contains the details necessary to exchange data. The ProviderConnectionPoint is associated with the provider, and the ConsumerConnectionPoint is associated with the consumer.

you must specify the following required attributes in addition to the id and runat attributes:

·       ConsumerID – Indicates the ID of the consumer control in the connection.

·       ConsumerConnectionPointID – Indicates the ID of a special callback method in the consumer used to establish the connection. This attribute is required only if the consumer has more than one connection point. For details on connection points, see ConnectionPoint.

·       ProviderID – Indicates the ID of the provider control in the connection.

·       ProviderConnectionPointID – Indicates the ID of a special callback method in the provider used to establish the connection. This attribute is required only if the provider has more than one connection point.
