...Logical Design and Physical Design CMGT 555/ Systems Analysis and Development Throughout the whole process of system development, there are designs that take place before any coding or setup takes place. During this time, phrases like logical design and physical design get tossed around a lot, but what are they and what do they mean? In short, the logical design defines what must take place, not how it is accomplished. The logical design is like a set of blue prints, it describes the actual processes of entering, verifying, and storing data. In this paper we will explain when logical designs and physical designs are used, what design information a logical design and physical design contain and any similarities or differences. Figure 1. Example of Logical Model and Physical Model for an ERD Relationship Diagram (Compare Logical and Physical ERD, 2009) The direct definition of a logical design “is the Conceptual Blueprint of a software application, illustrating entities, relationships, rules, and processes (Thibeault, 2011)”. So what is the logical design is used for? The logical design contains all the business entries, what each entries attributes are, and relationships among entries. Now the logical design to some is misleading because they often confuse it with detailed technical design, even though the goals for these two are not similar at all. Now when do we use the logical design? That question is simpler to answer; it usually starts during the requirements...

The phases are system planning and selection, system analysis, system design and implementation and operation. Since the planning and analysis phase have successfully completed, now we are continue with the next phase, which is systems design of the POS System in ARZA Coffee & Cakes. System design under System Development Life Cycle was a conversion of description of the recommended alternative solution into logical and physical specifications for the system starting from the input until the output screens consists of report, databases and computer processes. By that action the company might ease to reveals the real systems from which all the programming and system construction can be accomplish. This system could be implemented into any hardware and software since it is not tied up to any of the specific one. However, the logical design will illustrate the functions of the system in all aspects. In the physical design, the logical design will be interpret into the physical or technical specifications by convert the systems data to the structured systems design.

...Avinash Shankar Coleman University Database Integration – A framework The Physical Database Design depicts the actual structure of a set of relational tables specific to the platform and Database Management Systems (DBMS) on which the database is implemented. It is used to transition a logical data design into a physical database design that can be used to generate Data Definition Language (DDL). It also takes the current Systems environment into consideration, as well as some non-functional requirements. Basically the Physical Database Design is the implementation of the logical data design with any changes needed for physical considerations, such as capacity and performance. A physical database design is performed in three stages (LePendu, P., & Dou, D., 2011, p. 217 to 244): 1. Logical database design, which includes gathering of business requirements, developing a logical data model, and designing how to load the data 2. Conversion of the logical data design into a Physical Database Design includes table definitions, primary and foreign key relationships, and basic indexing 3. Post deployment Physical Database Design (often performed by a database administrator) includes improving performance, reducing I/O, and streamlining administration tasks. Data Integration Layer The data integration layer should be modeled in 3rd normal form or near 3rd normal form and is considered to be similar to an operational data design. In addition, the data integration layer...
