All of the following are stages in the SDLC except JAD. JAD is Joint Application Development.

Explanation:

  • JAD (Joint Application Development) is a methodology that involves the client or end user in the design and development of an application, through a succession of collaborative workshops called JAD sessions.
  • The JAD approach, in comparison with the more traditional practice, is thought to lead to faster development times and greater client satisfaction, because the client is involved throughout the development process. In comparison, in the traditional approach to systems development, the developer investigates the system requirements and develops an application, with client input consisting of a series of interviews.
  • JAD is a process used in the life cycle area of the dynamic systems development method (DSDM) to collect business requirements while developing new information systems for a company.
  • The JAD process also includes approaches for enhancing user participation, expediting development, and improving the quality of specifications.

explain why the database system would not allow a tuple to be inserted into the database through this view
Andrej [43]
For the view of Exercise 4.18, explain why the database system would not allow a tuple to be inserted into the database through this view.
For reference
For the database of Figure 4.12, write a query to find the ID of each employee with no manager. Note that an employee may simply have no manager listed or may have a null manager. Write your query using an outer join and then write it again using no outer join at all.
OUTER JOIN
select e.ID from employee e left outer join manages m on e.ID = m.ID
where m.manager_id is null;
NO OUTER
select e.ID from employee e where e.ID not in (select m.ID from manages m) or e.ID in (select m.ID from manages m where m.manager_id is null);

1. Hardware is the physical components that compose a system and provide physical quantity and quality to software applications and accomplish information processing tasks

2. Software is a program that carries out a set of instructions written in a programming language. It instructs a computer on how to carry out specific tasks. Programs can be saved permanently or temporarily.

3. Data may be mostly the raw resources used by information systems experts to give business intelligence to users. Traditional alphanumeric data, which is made up of numbers and alphabetical and other characters, is one type of data.

4. Networking is a resource of any computer system connected to other systems via a communications. It refers to the physical connections between all of the network's nodes. Communication networks are a critical resource component of all information systems, according to networking.

5. People are those who are directly or indirectly involved in the system. Direct users include developers, programmers, designers, and system administrators. Direct users can also be the stakeholder or end user who receives an output from the system. Indirect can be a manager who takes a brief check at the system to check that all criteria are satisfied.
