Database Design Process Database Life Cycle Key points Database design must reflect the information system of which the database is a part Information systems undergo evaluation and revision within a framework known as the Systems Development Life Cycle (SDLC) Databases also undergo evaluation and revision within a framework known as the Database Life Cycle (DBLC) There are two general design strategies exist: top-down vs. bottom-up design centralized vs. decentralized design 2

Abstract Database Systems has a practical‚ hands-on approach that makes it uniquely suited to providing a strong foundation in good database design practice. Database design is more art than science. While it’s true that a properly designed database should follow the normal forms and the relational model‚ you still have to come up with a design that reflects the business you are trying to model. This paper shows describes design process of database project. The importance of Completing the Design Process

Why good database design is important in performing data operation? A good design is significant in performing data operation. Without the good design‚ it is difficult to make relationship with other database and it will not run competently and also securely (Knight‚ 2011). This report will discuss the important of good database design‚ which are crucial for the business in performing operation and making a decision. Firstly‚ with the good design‚ data will be stored in consistent form. Appropriately

In order to create a database‚ organizations must determine what data to collect‚ who will access the data‚ and how the data will be use (Stair and Reynolds‚ 2012). After this information is determine‚ the database is designed. Database design has two parts. The first part is the logical design and the second part is the physical design. Logical Design The logical design is an abstract model which focus on what the system must do in order to meet the requirements of the organization’s needs

views are entirely different. The process view focuses on what the systems supposed to do and when‚ while the data view has a focus on what the system needs to operate. Another noteworthy difference that distinguishes the two views is the design stability. The design stability of a process view is a more limited approach because business processes and the applications that support them are forever changing‚ whereas a data view can stand the test of time easier because the data needs of an organization

Database Design Paper “A database is a structured collection of records or data that is stored in a computer system. In order for a database to be truly functional‚ it must not only store large amounts of records well‚ but be accessed easily. In addition‚ new information and changes should also be fairly easy to input.” (tech-faq.com); to ensure usefulness over the long-term‚ databases should be built with high data integrity and the ability to recover data if the hardware fails.

There are a variety of different databases and the type of database will determine how the data is arranged when it is stored and how that data will be located when it is called upon. At the company that I work for I know that they use Oracle®‚ which is an object-relational database

Logical Design Logical design takes each piece of conceptual design and assigns it to a specific logical role within architecture. For infrastructure projects‚ the architecture might be a series of block diagrams showing networks‚ service components‚ and network connection elements. Application architecture is typically broken down into at least three levels: presentation‚ business‚ and data level. Because this is a migration project‚ the team should document the existing logical design as well
