The application successfully demonstrates the distributed database operations as it allows the user to not only view the records of both London and Scotland sites, but also to manipulate the data by inserting new or updating existing records. However, still there is a lot of…

Currently, this application’s backend, SQL Server 2005, does not store any data locally. It simply contains two linked servers which are called whenever the application requires carrying out some data operation – viewing, inserting and updating records. Excessive communication with linked servers may result in increase of network traffic, hence, minimizing the performance of only the application itself but of the entire corporate network as well.
Therefore, it is very important to maintain some part of the data locally in SQL Server 2005 in order to reduce the network load by minimizing the communication with remote servers. This can be achieved through re-designing the database involving three key aspects – data fragmentation, data replication and data allocation.
Data Fragmentation refers to the process of breaking up the database into logical units called fragments which can be stored at different sites. The simplest logical units are the table themselves (Padigela, n.d.).
Fragmented or Partitioned refers to partitioning of database into disjoint fragments, with each fragment assigned to one site (no replication). This is also called ‘non-redundant allocation’ (Padigela, n.d.).
Complete Replication involves maintenance of a complete copy of database at each site (no fragmentation) and therefore, storage costs and communication costs for updates are main drawbacks of this strategy. To overcome this, snapshots – a copy of the data at a given time – are used to update copies of database periodically (Padigela, n.d.).

Distributed Computer System
The paper will critically look at the factors motivating the adoption of distributed systems in order to evaluate the reality of a true distributed computing environment. Description of current research on the development of appropriate sub-components of distributed computer systems will then follow. This paper will present a critical evaluation on the reality of having a true distribute system.

The other JVM can be on the same machine or any other machine on the network. However, the only thing it requires is for the JVM to be present at both sides. It implements remote interface developed by us and also language specifications, which is used by the server to provide the service as per the method call.

Distributed Systems assessment
In most implementations of MPI, a fixed set of processes is created at program initialization, and one process is created per processor. However, these processes may execute different programs. Hence, the MPI programming model is also referred to as Multiple Program Multiple Data (MPMD) programming model to distinguish it from the Single Program Multiple Data (SPMD) model in which every processor executes the same program, but on different data.
