Database design process Essay -- essays research papers
AbstractDatabase Systems has a practical, hands-on rise that makes it uniquely suited to providing a strong foundation in genuine database chassis practice. Database intent is more art than science. While its true that a properly knowing database should follow the normal forms and the relational personate, you still pull in to come up with a design that reflects the business you are exhausting to model. This paper shows describes design demonstrate of database project.The importance of Completing the Design appendageAn important point to keep in mind is that the level of geomorphologic integrity and data integrity is in direct proportion to how exhaustively the design process is followed. The less time spent on the design process, the greater the risk of encountering problems with the database. While thoroughly following the database design process may not eliminate all of the problems you may encounter when innovation a database, it will greatly help to minimize them. A lso in an RDBMS software program a well-designed database is easier to implement than a poorly designed database. (Michael J. Hernandez, 1996)     Key database Design ConceptsBefore a design effort flock proceed full speed ahead, the designer must first orchestrate time to understand the business. Understanding the business involves understanding the entities, data, and rules within an organization, and whence converting these attributes of the business into a business model. Then, the designer must have a solid comprehension of the proposed database model. Finally, the designer will convert the business model into a database model, using a design methodology, whether automated or a manual process.(Ryan Stephens & vitamin A Ronald Plew, 2002)General Design ProcessFollowing defer list general steps of database designStep     Description1     Requirements collection and analysis2     Conceptual databas e design3      election of a DBMS4     Data model mapping (also called ordered database design)5     Physical database design6     Database system implementation(Elmasri, Ramez, & Navathe, Shamkant B., 1994)Creating the application is the last stepnot the first Many developers transmit an idea for an application, bu... ... levels of normalization, but the primary levels are the first, second, and third normal forms. to each one level has a rule or two that must be followed. Following all of the rules will help ensure that your database is well organised and flexible.To take an idea from inception through to fruition, you should follow a design process. This process essentially says "think before you act." Discuss rules, requirements, and objectives, and then realise the final version of your normalized tables.Reference1.     Elmasri, Ramez, & Navathe, Shamkant B., Fundamentals of Database Systems, Second Edition, Addison-Wesley create Company, 1994, ISBN 0-8053-1748-1, pages 450-452.), retrieved from website http//www.ibiblio.org/faint/finosaur/db/ , Feb 06, 20052.     Michael J.
