suitable database are outlined and explained. These considerations have been developed by professionals through decades of research, implementation and first-hand experience. While they are not a fully set list of considerations, they are widely accepted as relevant and crucial to the developmental process. There are a number of important decisions that are needed when deciding on a suitable database. 1. Choosing the Database Model – Relational or Object etc. 2. Choosing the Database Genre/Size

1. Database Models The initial development of data storage started with the file system and these files have actually no relation or information of the application using these files. These files are accessed through the application containing the information or name of the files so these files cannot be considered as database but used to store information about the database. The application software is not aware of the structure of the file but as compared to it database management system consists

Comparing and Contrasting the Relational Database Model and OO Model The relational database model is based upon tables or relations. In this model, the physical implementation of the database is abstracted away from the user. Users query the database using a high-level query language, such as SQL. The relations are made up of columns, which have headings indicating the attribute represented by that column. Tables have key fields, which can be used to identify unique records. Keys relate tables to

relational database offers a solution to this menace. Data organization, keeping, storage, and retrieval among other essentials can easily be realized by adopting relational data management model. In this kind of model, tables are made use of in such a way that data items are formally described and organized according to their level of relations. The data item contained in a given table represents a relation. I am convinced beyond reasonable doubt that through the use of relational database model, an

Introduction As a requirement for our Database Management System I subject, we were assigned to create a database design model for a certain company. Since our instructor allowed us to select any company, we chose _____ ____ _____; further details about this establishment will be explained in the later part of this article. It’s been known that a company with a good business design flow would most likely be much more prone to success since it is the foundation on how a company should develop

subsection{Deductive Databases} In the field of deductive databases there has been extensive research on the optimization of queries for Datalog (and its variants). The major interest has been the optimization of recursive queries. Ceri et al~cite{ceri-gottlob-tanca-1989} provide an excellent summary of the field. The evaluation or comparison of optimization strategies is typified by Bancilhon and Ramakrishnan~cite{br1986,br1988} who develop analytical cost models for the optimization strategies
