Why do we need Data Mart?

-

 


  • Data Mart helps to enhance users' response time due to reduction in the volume of data It provides easy access to frequently requested data.
  • Datamart is simpler to implement when compared to corporate Datawarehouse. At the same time, the cost of implementing a Data Mart is certainly lower compared with implementing a full data warehouse.
  • Compared to Data Warehouse, a datamart is agile. In case of change in model, datamart can be built quicker due to its smaller size.
  • A Datamart is defined by a single Subject Matter Expert. On the contrary data warehouse is defined by interdisciplinary SMEs from a variety of domains. Hence, Datamart is more open to change compared to Datawarehouse.
  • Data is partitioned and allows very granular access control privileges. Data can be segmented and stored on different hardware/software platforms.

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...

Cloud Cube model   The Cloud Cube model helps classify a four-dimensional factor cloud network. Its concentration is on protecting and safeguarding the cloud network. This cloud cube model lets you securely pick cloud formation. This model serves to provide a safe and secured Internet network for IT administrators enterprises, and business leaders. Jericho cloud cube model  Jericho Forum is an international independent group of information security leaders & their focus is on how to protect and secure cloud networks. They put forward a model that helps to categorize a cloud network based on four-dimensional factors. The Jericho Cloud Cube Model describes the multidimensional elements of cloud computing, framing not only cloud use cases, but also how they are deployed and used. The Cloud Cube Model, established and developed by the Jericho Forum, assists in categorizing cloud networks based on four dimensions: Internal/External Proprietary/Open Perimeterised/De-perimet...

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...
