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

Design of Experiments (DOE) Tutorial Design of Experiments (DOE) techniques enables designers to determine simultaneously the individual and interactive effects of many factors that could affect the output results in any design. DOE also provides a full insight of interaction between design elements; therefore‚ it helps turn any standard design into a robust one. Simply put‚ DOE helps to pin point the sensitive parts and sensitive areas in designs that cause problems in Yield. Designers are then

Design concepts in architecture: the porosity paradigm Sotirios D. Kotsopoulos 129 Franklin Street‚ # 203‚ Cambridge‚ Massachusetts 02139‚ USA; e-mail: skots@alum.mit.edu Abstract: Presented is a paradigm of how a design concept can be converted into a system of production rules to generate designs. The rules are expressed by the means of shape grammar formalism. The paradigm demonstrates how porosity a concept transferred from biology‚ medicine and organic chemistry was implemented by architect

Benefits of a Hierarchical Network There are many benefits associated with hierarchical network designs. Scalability Hierarchical networks scale very well. The modularity of the design allows you to replicate design elements as the network grows. Because each instance of the module is consistent‚ expansion is easy to plan and implement. For example‚ if your design model consists of two distribution layer switches for every 10 access layer switches‚ you can continue to add access layer switches
