Part 3: Designing, Implementing & Maintaining the Solution

Conceptual Design: When implementing the distributed database, kernel loaded software will be installed on every client machine on the network. Every time an individual client machine is powered on, the distributed database will be powered on and begin filtering incoming traffic into every client machine (Özsu & Valduriez, 2011). This is a very important part of the process as it gives the advantages over the traditional firewalls. Traditional firewalls are implemented on the boundary of an internal network and an external network such as the internet. The firewalls treat the external network as risky while considering the internal network ...

Final Assignment

Both Bridges and Switches work on the data link layer of the OSI Model. However, switches are more advanced. Discuss how a switch has an advantage over a bridge in a network then elaborate more on the technology implemented in switches to control broadcast domains A bridge is a two interfaces device that creates two collision domains. This is because it forwards the traffic received from one interface only to the interface where layer two devices is connected (Olenewa, 2014). Bridges serves the main function of reading the destination of MAC address to forward the traffic only to the interface where it ...

Discuss how the data resource management methods of today will need to evolve as more types of data emerge

The need for data integrity continues to become a critical issue. Most of information such as client details or employee details being stored in databases that can be accessed through a network. Data resource management methods that do not provide the best security measures may result in losses for organizations implementing such methods. Additionally, data resource management methods are designed to handle a specified amount of data. The increase and enlargement of organizations requires them to apply methods that will reduce any incidences of inefficiencies while ensuring the data quality is maintained.

Why the role of a data steward is considered innovative?

A data steward ensures that an organization uses the latest ...

Homogeneous DDBMS – to define this, it will be necessary to know what a DDBMS. A DDBMS, full for Distributed Database management system is a software system that allows management of distributed databases and allows this management to be transparent to the users. A homogeneous DDBMS is an implementation where all sites make use of one product of database management system. One advantage of this is that it is easy to implement and allows incremental growth where new sites can be added to the sites with much ease. Heterogeneous DDBMS – in this setup, the database management system products are different ...

Abstract

This paper concerns the comparison between centralized and distributed database storage and management systems. The prime objective of the study is to explore the limitations of centralized databases and databank management systems and establish the how the limitations were overcome in distributed databases and database management systems. The challenges and the solutions are based on today’s business requirements and dynamic needs of organizations. The forcers which drove the shift from centralized to distributed platforms are explored and include the emergence of client-server architecture, Internet computing, local and wide area networks and the World-Wide-Web. The advancement of major structures ...

Need for distributed databases

Large business organization has increasing need of distributed database. These organization need distributed database because of its 1- Reliability 2- Accessibility 3- Scalability Distributed database provides an improvement for data processing and communication due to data distribution in different sites. Each database on different site may have different architectures and different management systems that distribute execution of transactions. In distributed database systems not only data access quicker, but failure of single-point occur less likely and users have local control over data.

Implementation of distributed database

Distributed database systems should be implemented by the process of multiple database servers at ...

Database management approach refers to the process of communication between users of a database and the database and the process of requesting data from the database, its retrieval and the mode of its transmission from the database to the user. Database management approaches are influenced by the mode of access to the database and the mode of storage of the data in the database. One of the database management approaches is the distributed database management system (DDMS) which has a single logical database physically divided among networked computers at different physical locations. Computers in the network communicate through messages. Distributed ...
