Describe EF core and its development approaches.

-

 EF core

• Is a new version of Entity Framework after EF 6. x.

• It is open-source, lightweight, extensible, and a cross-platform version of Entity Framework data access technology.

• Entity Framework is an Object/Relational Mapping (O/RM) framework. It is an enhancement to ADO.NET that gives developers an automated mechanism for accessing & storing the data in the database.

• EF Core is intended to be used with .NET Core applications. However, it can also be used with standard .NET 4.5+ framework-based applications.




EF core development  approaches

• EF Core supports two development approaches: (1) Code-First (2) Database-First.

• EF Core mainly targets the code-first approach and provides some support for the database-first.



• In the code-first approach, EF Core API creates the database and tables using migration based on the conventions and configuration provided in your domain classes. This approach is useful in Domain Driven Design (DDD).

• In the database-first approach, EF Core API creates the domain and context classes based on your existing database using EF Core commands. This has limited support in EF Core as does not support visual designer or wizard.

Pure Versus Partial EC

Pure Versus Partial EC EC takes several forms depending on the degree of digitization (the transformation from physical to digital). Companies utilizing pure EC conduct all of their business online. Businesses utilizing partial EC conduct a portion of their business online and a portion of their business off-line OR,    Pure E-electronic commerce refers to a situation where a business transacts its business activities PURELY online. that is, the goods or services sold do not have any physical presence. take a business that sells software, for example, you just pay and download, or one that sells music files online. Partial E-Commerce on the other hand refers to a slightly opposite situation where a business has an online presence, but still has a physical location for the goods and services it sells. For example, Amazon, Walmart, and any other you can think of. you buy the goods online but receive them physically.                   ...

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...
