Description: The research paper Data Warehouse Striping Technique (DWS) talks about Handling Big Dimensions in Data Warehouses using the striping technique. The research paper suggests that the DWS technique enables distribution of large data houses through a cluster of computers. The data partitioning technique partitions information and sends them across different nodes or access points. Dimension tables are also replicated. The replication of the dimension tables poses a restraint to the applicability of the DWS technique to data warehouses with big dimensions. This paper proposes a strategy to handle large dimensions in a distributed DWS system and evaluates the proposed strategy experimentally.

The DWS technique relies upon the typical star schema and the typical data warehouse queries to optimize the way data is partitioned among the computers in the DWS system and the way queries are distributed and executed. The typical infrastructure required to implement DWS is a cluster of inexpensive computers connected via Ethernet and a DBMS installed in each node. All the nodes have a same star schema and dimensions are replicated in each node. The fact data is also installed to share the facts at each node. The uniform partitioning is necessary to assure optimal load balance and to facilitate the computation of confidence intervals in the cases (rare, in principle) when one or more nodes in the system are not available.

Conclusion: The research paper concludes over a note saying that a new technique called the ‘selective’ load is developed to overcome the limitations of the DWS technique in handling Data Warehouses. The suggested technique helps managing data warehouses more effectively and efficiently, maintaining nearly linear speed up in query execution time. The experiments performed with the TPC-H schema and queries have suggested that the selective load improves dramatically the performance of a DWS system when processing queries in data warehouse scheme with potentially big dimensions.

Description: The research paper Grid Construction Distributed Computing talks about Grid Computing and how it is achieved. The research paper suggests that grid computing is nothing but distributed computing taken to a new evolutionary level. Grid computing creates an illusion of large, virtual, self-managing computer. In grid computing several computers are connected and share information and resources via server pools. The aim of grid computing is to provide faster, secure and effective internet solutions, in the ever growing world wherein the demand for internet is growing day by day. The research paper also suggests that not all systems can become scalable over a grid. Grid computing also enables smooth and successful customer interaction. Grid computing also aims at a more refined collaboration between users.

What is data grid: Sharing in grid computing starts with sharing of data from the data bases via the data grid, a data grid can enhance the capabilities of this functioning in many ways. The files of data seamlessly span over many systems thus making the usability enhanced. Such spanning could improve data transfer rates. While the Resource layer is focused on interactions with a single resource, the next layer in the architecture contains protocols and services (and APIs and SDKs) that are not associated with any one specific resource but rather are global in nature and capture interactions across collections of resources.

Advantages of grid computing: High end traditional computing requires installation of costly hardware components. Grid computing on the other hand facilitates cost effective computing.

Conclusion: The research paper concludes on a note that grid computing enables faster sharing of files in an internet medium. Grid computing also makes downloading possible without playing foul with the system features by slowing it down or crashing it. Grid computing also makes it unnecessary to restart the system time and again.

Description: The research paper Grid Computing and Advantages Final MCA Seminar Topics talks about Grid Computing and how it is used to manage computers that are networked. The colossal rise in computing technologies and sharing network has raised the interactivity levels of the computer. The research paper suggests that when we are talking about internet we should consider a basic fact that there is an interaction between the system (server) and the client. There is generally lots of sharing of information and data when we are working in a distributed computing environment. However simple the act of browsing might be there is certainly a interaction with the other side of the world.

Distributed computing may be simplified as breaking down the bigger processes of computers in smaller manageable ‘agents’. These agents work together to pursue a cooperative task. This way breaking don things into smaller components will enable to work qualitatively on a particular task. Result thus obtained will be of enhanced quality and accuracy. The entire thing is cost effective too. Assorted tools and standards for assembling distributed computing applications have been developed over the years. These started as low-level data transmission APIs and protocols, such as RPC and DCE, and have recently begun to evolve into object-based distribution schemes, such as CORBA, RMI, and OpenDoc. These programming tools essentially provide a protocol for transmitting structured data over a network connection. Java offers a language and an environment that encompass various levels of distributed computing development, from low-level network communication to distributed objects and agents, while also having built-in support for secure applications, multiple threads of control, and integration with other Internet-based protocols and services.

Conclusion: The research paper concludes suggests that distributed computing is the domain that is gaining momentum faster than expected. Scientists believe that distributed computing allows reaching a better and simpler, faster solutions for complicated processes.
