.NET Platform:NET, is a platform, its sort of a runtime environment on which applications coded in any of the managed languages run. The .NET runtime environment acts as software layer between the applications written on the .NET and the operating system (or hardware). This is what actually gives programs written on .NET, Java like functionality of write once and execute anywhere subject to the fact that you have the .NET runtime system installed for your platform and CPU
C#:
C# is the new modern language for
developing applications for Microsoft's .NET platform. The .NET platform
is designed to be language neutral, indeed, all .NET code is run under
the Common Language Runtime (CLR). C# is just one of the languages that
can be used to write classes for the CLR, but so far it is the only language
that was written from the outset with .NET in mind. This makes C# as the
language of choice for .NET development
Web Service
Web Services are a very general
model for building applications and can be implemented for any operation
system that supports communication over the Internet. Web Services use
the best of component-based development and the Web. Component-base object
models like Distributed Component Object Model (DCOM), Remote Method Invocation
(RMI), and Internet Inter-Orb Protocol (IIOP) have been around for some
time
Steps involved in Alignmnet:
1:Taking the Two input Strings
2:Calculating the Dyanmic
Matrix
3:Trace Back through the
Matrix to achieve the Best Alignment
The formulae used for geneartion of Dyanmic Matrix:
1:H [i,j]=Max(Diagonal,Vertical,horizontal,0)
2:Diagonal=H[i-1,j-1]+Match/Mismatch(A[i],B[j])
3:Vertical=Max Value of Vertical Gap
Cell-(gap penalty-(gap extension penalty*distance))
4:Horizontal= Max Value of Horizontal
Gap Cell-(gap penalty-(gap extension penalty*distance))
Where :
Match/Mismatch , Gap Penalty ,Gap Extension
penalty has to be enetered by the user
Implementation Model:
The Project has three main pages:
1: Login Page
2: DNA Alignment Page
3: Interactive Learning
Page
Client Side:This is the user interface side.The first
page that appears when we load the website is a User Login Page , the user
has to enter his login name and password to access
the features of the Web Site.If the user enter his login name and
password combination wrong for more than three times the Session with the
Server is broken.He has to restart the Browser to initiate the session
between the Client and the Web Server.Once the user logs in he comes across
the page where he has to enter two DNA string Then when he hits the Alignment
Button he comes up with Dynamic Matrix and the aligned string.If the user
leaves the Text box empty and tries to hit the
We have a link to interactive learning there.Upon clicking that link
he is directed to the page where he has to enter DNA strings and upon hitting
the button we display how the values is being obtained(Diagonaly,Horizontal,Vertical)
and finally the Grid is displayed with the Trace Back Path.
Web Server: At web server we have the program running
that is responsible to calculate the Dyanmic Matrix and the Text Alignment.
At the first page where upon entering the DNA we get the o/p at once ,
we send the DNA string to the Web Server.The program take the Input.Returns
us the DataSet having two data tables .In one data table we have the Values
for the Dynamic Matrix and the Second table consist of the
Aligned text with their locations in the Matrix. Finally the Data
tables are binded to the Data Grid and then as per the Locatins returned
we highlight the String.
At the Interactive Learning section every time the Input is send at
the Server side and every time the Data Set is being returned. We only
highlights the value that we are interested in , and at last we display
the whole Dynamic Matrix with the Aligned Text.
Login Page: This is the first page that comes when
user loads the URL. Here he is asked for his User Id and Password, A correct
combination takes him to DNA ALIGNMENT PAGE
After the User has entered the right combination of User Id and Password ,at the Next Page he is asked to input DNA Strings , Gap Penalty , Gap Extension , Match and Mismatch Values
DNA Alignmnent Page:
On Entering the Required Values and Upon Hitting Align Button the User is displayes DYNAMIC MATRIX , TRACE BACK PATH and Aligned Strings.
We have a link to interactive learning page . At clicking this link he has to enter required parameters again.Here at every click of ALign button the DYNAMIC MATRIX is loaded and displayes with the Info about how we have acheieved that Value.After the whole Dynamic Matrix has been initialized at the last click the trace back and aligned strings are displayed.
