Answer:
Manipulation
Explanation:
The DBMS subsystem that provides for data maintenance, analysis, and the generation of reports is called the data manipulation subsystem. It allows the user to modify data by adding or deleting information in the database. The user can also query the database to gain access to valuable information. The software that is used in the data manipulation subsystem serves as an interface between the data contained in the database and the user.
 
        
             
        
        
        
The answer is the Transition element.
A slide transition in PowerPoint occurs when you move from one slide to another during a presentation. You can control the speed (time spend on a single slide before advancing to the next). We use set duration to set the transition speed. To set the transition speed to a shorter or a larger duration, select the slide and click on the Transitions tab in the Timing group. In the Duration box, type the number of seconds that you want.
