Examine about the Behavioural Diagrams
The main objective of behavioural diagrams is to visualize, specify, construct and document dynamic aspects of a system. The interaction among objects indicating flow of control between them is shown using these diagrams. The flow of control can encompass a simple, sequential thread from a system, as well as complex flows which involves branching, looping, concurrency and recursion. They could model sequence of messages (collaboration diagram) or time ordering (sequence diagram). The four major behavioural diagrams are: use case, activity, interaction and state chart diagram.
There are two major types of fragmentation: Horizontal& Vertical. Horizontal fragments, as the name suggests are subsets of tuples and vertical fragments are subsets of attributes
Explain the term- signal-to-noise ratio A signal-to-noise ratio of 20 dB means that S/N = 100. As log2101 is around 6.658, the Shannon limit is around 19.975 kbps. The Nyquist
Process of implementing system design in dynamic models There are three essential approaches to implementing system design in dynamic models. These approaches are as below:
Give an example of operations from the State Actions and Activities. For instance, in bank the activity verify account code and verify password

Create a view emp_dep containing e_name and number of dependents from the tables employee and dependent of (i) CREATE VIEW emp_dept AS SELECT ename, COUNT(*) FROM employee, dep
Differentiate between a subquery and a join If we need to acquire information from one or more tables after that either subquery or join can be used. If the columns which are t
