Several disadvantages of distributed data processing have been discussed discuss at least three

Distributed processing is done with high Internet speed like querying the database. Easy to expand: Suppose your company needs more data processing than expected then you can easily attach more computers to the distributed network.

Several disadvantages of distributed data processing have been discussed discuss at least three

Lack of Standards Although distributed DBMSs depend on effective communication, we are only now starting to see the appearance of standard communication and data access protocol s. PTS:1 8. Easy to replace remote computers: Microsoft Windows server has a feature called failover clustering that helps to remove faulty computers. The infrastructure must also be secured for example, by encrypting the network links between remote sites. However, in a distributed DBMS not only does access to replicated data have to be controlled in multiple locations but also the network itself has to be made secure. In a distributed DBMS, the communication and processing costs that are required to enforce integrity constraints are high as compared to centralized system. Context Many of the issues considered in other chapters of this module require a degree of further consideration when translated into a distributed context. Distributed data processing is more reliable, since multiple control centers are spread across different machines. PTS:1 9. This flexibility allows an organization to expand relatively easily.

The most commonly stated benefits of DDP are cost savings, increased user satisfaction, and improved operational efficiency. Data is more available in this scheme.

This flexibility allows an organization to expand relatively easily. For any type of query or something that you think is missing, please feel free to Contact us. Usually the SQL database language is used for this purpose. Related Articles. Review question 1 Explain what is meant by the 2-tier model of client-server computing. The homogeneous system is much easier to design and manage. So the data is synced and available to all computers. Distribution of decision making can result in a lack of standards. The server is also freed to concentrate on data-intensive operations, i. This arrangement also falls under the 2-tier model, as it still only comprises the two types of machine within the network. Transactions must also be divided into sub-transactions, each sub-transaction affecting one database system. A visit to the software's website maybe also be useful. Optimized processing: Managing data on online server solves slow processing. So data processing is optimized. Suppose there are different office branches interconnected to each other.

The infrastructure must also be secured for example, by encrypting the network links between remote sites. The following conditions must be satisfied for homogeneous database: The data structures used at each location must be same or compatible.

Economic events are actions that affect changes is resources. All branch computers are interlinked with the main branch office. With this configuration, the client machines are freed up to focus on the validation of data entered by users, and the formatting and presentation of results. Distributed data processing is more reliable, since multiple control centers are spread across different machines. The fact that data can be replicated also adds an extra level of complexity to the distributed DBMS. Modular growth In a distributed environment, it is much easier to handle expansion. There are also additional labor costs to manage and maintain the local DBMSs and the underlying network. On heterogeneous system, translations are required to allow communication between different sites or DBMS. If we choose to place all the business logic in stored procedures on the server, we reduce network traffic, as intermediate SQL results do not have to be returned to client machines. Delegation of cost control to individual units leads to more efficient use of unit resources. Though the use of stored procedures improves performance by reducing the load on the clients and network , taking this too far will limit the number of users that can be accommodated by the server — i.

Faulty machines are quickly isolated and repaired. The system is flexible also in terms of increasing or decreasing processing power.

Data can be placed at the site close to the users who normally use that data. Distinguish between the accounting information system and the management information system.

All data from different computers are processed in parallel. This lack of standards has significantly limited the potential of distributed DBMSs.
