 Main Components of .NET Framework


1. Common Language Runtime (CLR):- CIR is the basic and Virtual Machine component of the NET Framework. It is the run time environment in the NET Framework that runs the codes and helps in making the development process easier by providing various services such as remoting, thread management, type-safety, memory management, robustness, etc. Basically, it is responsible for managing the execution of NET programs regardless of any .NET programming language. It also helps in the management of code, as code that targets the runtime is known as the Managed Code, and code that doesn't target to runtime is known as code Unmanaged code.

Language - The programming language is at the first level and the most common ones are VB.NET and C#

 Compiler - There is a compiler that will be separate for each programming language. So, underlying the VB.NET language, there will be a separate VB.NET compiler. Similarly, , for C#, you will have C# compiler.


2. Common Language Interpreter: This is the final in which would be used to run a .NET program developed in any programming language. So, the subsequent compiler will send the program to the CLI layer to run the .NET application.




Framework Class Library (FCL): It is the collection of reusable object-oriented class libraries and methods, etc. that can be integrated with CLR Also called the Assemblies. It is just like the header files in C/C++ and packages in java. Installing the NET framework basically is the installation of CLR and FCL into the system.


3. Applications

The types of applications that can be built in the .NET framework are classified broadly into the following categories.

Net-Centric Computing Win Forms: This is used for developing Forms-based applications which would run on an end-user machine. Notepad is an example of a client-based application.

ASP.NET: This is used for developing web-based applications, which are run on any browser such as Chrome, Firefox, etc. The Web application is processed on a server, which would have Internet Information Services (IIS) Installed, IIS is a  Microsoft component that is used to execute an Asp.NET application. The result of the execution is then sent to the client machines, and the output is shown in the browser. 

ADO.NET: This technology is used to develop applications to interact with Databases

Suppose that a data warehouse for Big-University consists of the following four dimensions: student, course, semester, and instructor, and two measures count and avg_grade. When at the lowest conceptual level (e.g., for a given student, course, semester, and instructor combination), the avg_grade measure stores the actual course grade of the student. At higher conceptual levels, avg_grade stores the average grade for the given combination. a) Draw a snowflake schema diagram for the data warehouse. b) Starting with the base cuboid [student, course, semester, instructor], what specific OLAP operations (e.g., roll-up from semester to year) should one perform in order to list the average grade of CS courses for each BigUniversity student. c) If each dimension has five levels (including all), such as “student < major < status < university < all”, how many cuboids will this cube contain (including the base and apex cuboids)?

a) A Snowflake Shema is shown in figure below: b) The specific OLAP operations to be performed: 1. Roll-up on course from course_id to department. 2. Roll-up on a student from student_id to university. 3. Dice on course, student with department ="CS" and university = "biguniversity" 4. Drill-down on a student from the university to student_name. c) N = 4 dimensions The cube will contain 54 = 625 cuboids.

Discuss classification or taxonomy of virtualization at different levels.

Taxonomy of virtualization Virtualization is mainly used to emulate the execution environment, storage, and networks. The execution environment is classified into two: – Process-level – implemented on top of an existing operating system.  – System-level – implemented directly on hardware and does not or minimum requirement of the existing operating system. OR,  Virtualization covers a wide range of emulation techniques that are applied to different areas of computing. A classification of these techniques helps us better understand their characteristics and use  V irtualization is mainly used to emulate  ● Execution Environments: To provide support for the execution of the programs eg. OS, and Application.  ○ Process Level: Implemented on top of an existing OS that has full control of the hardware  ○ System Level: Implemented directly on Hardware and do not require support from existing OS.  ● Storage: Storage vi...

Short note on E-Government Architecture

-
Image
1)  Presentation layer The presentation layer identifies and describes the system users, who require access to government information at different capacities, and the channels through which information can be accessed.  During system development, one is required to explicitly identify the government user, the system is intended to serve, and also the means through which this information is to be accessed so that the system can be tailored to meet these requirements. It manages the user’s interface with the system. If a pro- project is to be successful, different stakeholders need to be identified at the beginning, involved in the initial stages and kept involved throughout development and implementation. 2) E-government layer E-government public services utilize very specialized applications that are only available to certain agencies and not all agencies participating in the consortium. The main goal of the e-government layer is to achieve a government that;  does not as...
