<!-- @page { size: 8.5in 11in; margin: 0.79in } P { margin-bottom: 0.08in } -->
In the Web application development, three-tier architecture can be defined as the process of separating the application into three parts or layers. These are:
- Client Tier, also called as Presentation Tier or User Interface
- Middle Tier, or Application Tier or Business Logic
- Data Access or Data Storage Tier
These three-tier web and software development is a logical, three-tier architecture implemented in one or more layers are applied to ensure better performance and scalability. Affordable Web development, and eventually use the results.
An ideal web development in India uses the multi-tier architecture is right for the development, updating or redesigning web site. Web
Well, we have an in-depth look at these three stages:
Client Tier:
The Client tier or user interface is what the user sees after accessing a web page in the browser. The web page accessed by the user is on the client side within the browser. The content is served from the web server. While an average internet user cannot view any behind-the-scenes processing, developers have the ability to separate the client tier from data access and application tier with various tools. The most common languages used in this layer are HTML, JavaScript, CSS and DHTML.
Application Tier:
The application layer shall be kept on a separate layer. Here Web
Data Storage or Access Tier:
The data storage layer lets developers define tableadapters and datasets. Developers define queries and stored procedures in this layer. For example, if developer wishes to create a web form, he has to first create a tableadapter and dataset. These two will use query or procedure to allow users to insert information into the table. A class is created to retrieve the information from the web form. It validates the fields and then the tableadapter is used to send data to the database.

Two of the main things, the data of this approach is working. The work of these two different ways.
The approach of the database file server, data stored in a file, users need to get data directly from a file. Directly changed when the file is open is made on the application. Data files and writes these files. If the user data 10 and 10 who have been working to write the file.
In the client-server approach is still the data is stored in a file, but from a server, all servers in the access control hand. When to apply for any would like to use existing data, and then use the application send a request to the server. To read later, the server requests and send feedback. When to apply for any you want to write the request in the file sent to the server on the server, something written on the document. A person from the read and write data files.
Oracle, Informix, Microsoft SQL Server are the best suit for example, client-server databases. Single-user desktop, such as Microsoft Access.
There are lots of advantages of client server databases.
Changes or accidental crash data) less chance of data read and write a single program.
2) Only single program play good role of security so enforcement of security is easy.
3) and more efficient client-server databases, database files using the server's network bandwidth.
4) All things are handling by single computes so performance is good and quite impressive.
5) The client-server database on the use of some good features, like a record transactions and to protect the disk and network errors, restore our data.
Some of these features also in the file server approach can be used, you need these more expensive client-server market. Also, you can learn a dot net interview questions for many.
Ajax Form Validation and Thread-safe Ajax
This degradable form validation demo verifies the form at the server side on the classic form submit, and also implements AJAX validation while the user navigates through the form.
Degradable AJAX Form Validation
Doing a final server-side validation when the form is submitted is always a must. If someone disables JavaScript in your browser settings, AJAX validation on the client side will not work exposing sensitive data, and thus an evil to visitors the important data back) on the server (for example, damage caused by SQL injection. Always validate user input on the server!
This form validation application validates a registration form, using both AJAX validation (client side) and typical server-side validation:
* AJAX-style (on the client side), when each form field loses focus (the onblur). The field's value sent to the server, which validates the data and return results (0 for failure, success 1). If the validation fails, an error message will quietly appear and notify the user of the validation failure.
* PHP style (on the server) you will be sent to the entire form. This is for a particular rule, if you check the user input validation is not always what server. If no errors, if found, the input data is valid, the browser will be redirected to a page successfully. If the validation fails, however, the form page the user is again stressed that sent the invalid field.
Both AJAX validation and PHP validation check the entered data against these rules:
* Username must not already exist in the database
* Name field cannot be empty
* A gender must be selected
* Email address must be written in a valid email format, such as xyz@domain.com
* Phone number must be written in standard US form: +xx xxxxxxxxx
Thread-Safe AJAX
Some threads of the code will function correctly when it is safe when multiple concurrent threads. In this exercise, we have to make asynchronous requests to the server, the user input box and change every time you need to input data to validate the selected leaves.
The technology behind the hidden, but said, if the user input fields will soon be passed, or the server connection is slow, in this case, Web application will attempt to XMLHttpRequest object through a request for a new server is still busy to wait for a response in the previous request (which will generate an error, the application will not function properly).
Depending on the circumstances at hand, the ideal solution to this problem may be:
If you are new to all messages sent to the server must create an instance of the XMLHttpRequest *. To implement this method is simple, if multiple requests are sent to the same time, can degrade the performance of the server, it does not guarantee the order and receive a response.
* Record the message in a queue and send it later when the XMLHttpRequest object is able to make new requests. The requests are made in the expected order. Using a queue is particularly important in applications where the order of the messages is important.
* Schedule automatic re-trial was made after the specified time requirements. This method is similar to a queue and you do not let more than one time server's request, but does not guarantee the order in which requests, or in the order the responses received.
* Ignore the message.
In this form validation exercise, we use a message queue. When the user leaves an input element, a message to validate its value is added to the queue. When the XMLHttpRequest object is clear to make a new request, it takes the first message from the queue.
Queue is a first in first out (FIFO) structure, which guarantees the correct order to send e-mail. To obtain information on how to work, to demonstrate the feeling of pages and then press the TAB key to fast times, and then wait to see reaction to verify that the display one by one.

AJAX Functionality in ASP.NET 4.0
The AJAX functionality in ASP.NET 4.0 enables new client data scenarios for page and component developers that allow JSON data from the server to be rendered as HTML in a highly manageable and efficient way. To enable these scenarios, ASP.NET 4.0 includes the following major features:
- Client-side template rendering.
- Declarative instantiation of client-side behaviors and controls.
- Live data binding.
- Use of the observer pattern with JavaScript types.
- An AdoNetServiceProxy class for client-side interaction with ADO.NET Data Services.
- A client-side DataView control for data-bound UI in the browser.
- DataContext and AdoNetDataContext classes for interaction with Web services.
- Refactored ASP.NET AJAX framework libraries.
Client Template Rendering
In client-based development, templates are the most manageable way of creating UI from data. ASP.NET 4.0 includes a new template engine for client development that meets the following requirements:
- Performance — The engine must be able to render a typical number of items using a reasonably complex template before users perceive an interruption in their interaction with the application.
- Simplicity — The template syntax must be very readable and must be optimized for the most common scenario, namely one-way/one-time binding.
- Expression language — Templates must support an expression language to go beyond the simplest cases. The expression language should use familiar syntax, ideally JavaScript syntax.
- Interspersed code and markup — It must be possible to perform conditional rendering or to loop over markup by using code that surrounds HTML.
- XHTML compliance — The template should be able to render XHTML-compliant markup.
- Components — When using the template syntax, the developer must be able to instantiate client-side controls and behaviors that attach to HTML elements in the page or within templates.
