Before you implement a database, you should plan or design the database so that it satisfies all requirements. Designing and implementing a successful database, one that satisfies the needs of an organization, requires a logical data model. Logical data modeling is the process of documenting...
Synonyms Logical schema design ; Data model mapping Definition Logical database design is the process of transforming (or mapping) a conceptual schema of the application domain into a schema for the data model underlying a particular DBMS, such as the relational or object-oriented data model. ...
The logical database design approach defined here uses both the conceptual data model and the relational model in successive stages. It benefits from the simplicity and ease of use of the conceptual data model and the structure and associated formalism of the relational model. In order to facilita...
Entity-relationship logical design of database systems: relational normal forms and extended regular ERDs robust database systemsrelational databasesThe design of the logical structure of databases using the entity-relationship (E-R) model is considered.

The logical data model is effective however for communicating the designers’ view of the information to business analysts on application development teams and to database administrators who will perform the physical database design phase. Once the business analysts confirm that the logical data model ...

Having to return to the drawing board late in the project because of some unanticipated requirement will all but guarantee wasted effort, wasted resources and wasted time. The collective decades of experience that we bring to bear in optimizing a database relational model to suit a specific busine...
normalisation alone does not produce a good design. In the end, ensure that both logical and physical designs are consistent with each other. Run your final scripts to generate the database (i.e., physical model). Use your Group Oracle a/c to implement the final DDL code. ...
As its name implies, structured data requires proper design; to this end, two fundamental approaches to structured data modeling have become fixtures in the enterprise database world: logical data models and physical data models. Logical data model. These high-level, abstract representation of data...
