Sandhya.Kishan- Member Since Mar-2012 | May 14th, 2012
1.MVC1 consists of Web browser accessing Web-tier JSP pages. The JSP pages access Web-tier JavaBeans that represent the application model, and the next view to display is determined by hyperlinks selected in the source document or by request parameters. 2.MVC1 is page-centric design, meaning any JSP page can either present in the JSP or may be called directly from the JSP page. 3.MVC1 Combines both presentation logic with the Business logic. 4.MVC1 we can have multiple controller servlets. 1.MVC2 introduces a controller servlet between the browser and the JSP pages. The controller centralizes the logic for dispatching requests to the next view based on the request URL, input parameters, and application state. 2.MVC2 removes the page-centric property by separating Presentation, Control logic and Application state. 3.MVC2 can have only one controller servlet .

Visual Studio uses partial classes to separate auto-generated code from user-generated code. Example:Let us consider that visual studio creates a file called Form1.Designer.cs which holds the designer-related, auto-generated code. So in both Form1.cs and Form1.Designer.cs the Form1 class is declared as partial and the compiler joins them into one.

Editorial / Best Answer
Sandhya.Kishan- Member Since Mar-2012 | Jul 4th, 2012
Raster data is a set of horizontal lines composed of individual pixels, used to form an image on a CRT or other screen.Raster data makes use of matrix of square areas to define where features are located. These squares are typically of uniform size, and their size determines the detail that can be maintained in the dataset.Raster data represent square areas, they describe interiors rather than boundaries. Vector data use X and Y coordinates to define the locations of points, lines, and areas (polygons) that correspond to map features, vector data tend to define centers and edges of features.They are excellent for capturing and storing spatial details
