phases of database design pdf

A Database Design Methodology University Of Maryland. The software development lifecycle (SDLC) typically includes a requirements phase, design phase, implementation phase, testing phase, operation and maintenance phase, and sometimes, retirement phase. The database development life cycle (DDLC) is a part of ( or embedded inside) the software development life cycle. Figure 1 gives the various SDLC phases and their relationship with DDLC., In a sense, logical design is what you draw with a pencil before building your warehouse and physical design is when you create the database with SQL statements. During the physical design process, you convert the data gathered during the logical design phase into a description of the physical.

Schematic Diagram Of The Phase Of Database Design Triac

Database Development Life Cycle Myreadingroom. The result of the conceptual design phase is a conceptual data model (Figure 3), which provides little information about how the database system will eventually be implemented. The conceptual data, The output of the database design phase is a series of instructions detailing the creation of tables, attributes, domains, views, indexes, security constraints, and storage and performance guidelines. In this phase, you actually implement all these design specifications..

To have optimum performance, storage and fast retrieval of data, database design is an important phase in the detailed design of a system. For designing a database, the designer should keep the following points in mind. The design phase is where the requirements identified in the previous phase are used as the basis to develop the new system. Another way of putting it is that the business understanding of the data structures is converted to a technical understanding.

phases exists. When creating a database system the feedback between some of the life cycle phases is very critical and necessary to produce a functionally complete database These define the core stages in the design process of a database. The models at each of the three levels of abstraction correspond to Model Driven Architecture (MDA) concepts.

In a sense, logical design is what you draw with a pencil before building your warehouse and physical design is when you create the database with SQL statements. During the physical design process, you convert the data gathered during the logical design phase into a description of the physical during later phases of the project may alter some design decisions so the nice neat diagram of the 6 phases is really an iterative process where each stage feeds back to the previous stages.

Design phase is intended towards addressing how the system is to be implemented. Software design process is an art or an inexact science. If it is purely a mechanical process by which a specification is translated into a design of an efficient program, then this process follows an exact or deterministic science. DESIGN QUALITY-1 Budgen(1993) describes some of the ‘ilities’ that form a Overview. Once the conceptual design is finalized, it's time to convert this to the logical and physical design. Usually, the DBMS is chosen at this stage, depending on the requirements and complexity of the data structures.

    database. Database design involves constructing a suitable model of this information. Since the design process is complicated, especially for large databases, database design is divided into three phases: • Conceptual database design • Logical database design • Physical database design. CONCEPTUAL DATABASE DESIGN Conceptual database design involves modelling the collected information at For this reason, some database design methods refer to two separate design stages: logical database design and physical database design. However, this physical stage is mainly concerned with producing a revised logical schema – that is, specifying SQL tables – so this terminology can be confusing. The tables of a logical schema may differ from the relational representation of the
