Preserving the accuracy and the integrity of information in a database is extremely important for the organization that is maintaining that database. Such an organization is likely to rely heavily upon that accuracy. Applications that consult and use the database expect a guarantee that the database is supplying the correct information. Critical business decisions may be made assuming that information extracted from the database is correct. Thus, incorrect data can lead to incorrect business decisions, which can have serious implications for the people and organizations using it (Codd, 1990).

Distributed database management systems manage a huge amount of data as well as large and increasingly growing number of users through different types of queries. Therefore, efficient methods for accessing these data volumes will be required to provide a high and an acceptable level of system performance.  Data in these systems are varying in terms of types from texts to images, audios and videos that must be available through an optimized level of replication. Distributed database systems have many parameters like data distribution degree, operation mode and the number of sites and replication. These parameters have played a major role in any performance evaluation study. This paper investigates the main parameters that may affect the system performance, which may help with configuring the distributed database system for enhancing the overall system performance.
