Question 1 :
There is one physical schema for each logical schema.
Question 2 :
The most important reason for data architecture is reliability.
Question 3 :
The systems development life cycle cannot be used with database implementation.
Question 4 :
Enterprise data modeling typically occurs during information systems planning.
Question 5 :
During logical database design, the conceptual data model is transformed into a logical data model which describes the data in terms of a specific data management technology.
Question 6 :
A conceptual schema is usually depicted in graphical format using E-R or object-modeling notations.
Question 7 :
The physical database design identifies data integrity and security requirements.
Question 8 :
The longest step of database development is database maintenance.
Question 9 :
Incremental commitment does not allow a project to be easily redirected or to be terminated.
Question 10 :
There are three stages involved when analyzing the initiation of an information systems project.
Question 11 :
One of the most popular systems development life cycle methods is prototyping.
Question 12 :
The goal of information systems planning is to align information technology with the business strategies of the organization.
Question 13 :
Functional decomposition is the process of breaking down the functions of an organization into greater levels of detail.
Question 14 :
Packaged data models can reduce implementation times and costs.
Question 15 :
With an enterprise data model, it is much easier to build applications because you know exactly what data exist and what needs to be added.
