How do you approach a database design?
There are two approaches for developing any database, the top-down method and the bottom-up method. While these approaches appear radically different, they share the common goal of utilising a system by describing all of the interaction between the processes.
What is 2nd normal form with example?
The second step in Normalization is 2NF. A table is in 2NF, only if a relation is in 1NF and meet all the rules, and every non-key attribute is fully dependent on primary key. The Second Normal Form eliminates partial dependencies on primary keys.
Which is a top down approach of database design?
A top down approach is used to create a new database. You model the objects at a logical level, then you apply the objects to a physical database design. For example, a relational database would need the objects to be mapped to tables.
Which of the following is a type of design review?
An informal review involves those individuals directly involved in the design project. Formal reviews include applicable subject matter experts who are not directly involved in the design but can review and comment on the design. Technical reviews involve subject matter experts and deal solely with technical issues.
Why are design reviews important in database development?
The Importance of Database Design Reviews. Design reviews are an important facet of the system development lifecycle for database applications. It is during the design review that all aspects of the database and application code are reviewed for efficiency, effectiveness, and accuracy.
Why is it important to do a design review?
The design review is an important process for checking the validity of design decisions and correcting errors before applications and databases are promoted to production status. Multiple design reviews should be conducted over the course of an application’s life.
What should be included in a design review checklist?
The design review checklist is a compilation of information intended to address the design of a solution that meets the project requirements. Indicate whether the design deliverable listed below is applicable to the solution. Each deliverable indicated as applicable must be documented and included in the design review package.
