Answer:
"The employee pay rate is normal" is the correct answer for the above question.
Explanation:
- The above question code is written in the c++ language, in which there is one variable of bool type whose value is true.
- And this variable is also tested in the if-condition which gives the true and the if-body will be executed.
- Then the internal if-condition will give the false result because the value of the empsalary is not less than 45000. It is because the above statement "empsalary=45000" will assign the value 45000 on the empsalary variable.
- Then the else block will be executed which prints "the employee pay rate is normal".

Case-based reasoning.
Explanation:
A database management system (DBMS) can be defined as a collection of software applications that typically enables computer users to create, store, modify, retrieve and manage data or informations in a database. Generally, it allows computer users to efficiently retrieve and manage their data with an appropriate level of security.
A data dictionary can be defined as a centralized collection of information on a specific data such as attributes, names, fields and definitions that are being used in a computer database system.
In a data dictionary, data elements are combined into records, which are meaningful combinations of data elements that are included in data flows or retained in data stores.
This ultimately implies that, a data dictionary found in a computer database system typically contains the records about all the data elements (objects) such as data relationships with other elements, ownership, type, size, primary keys etc. This records are stored and communicated to other data when required or needed.
Basically, when a database management system (DBMS) receives data update requests from application programs, it simply instructs the operating system installed on a server to provide the requested data or informations.
Case-based reasoning is a problem-solving technique where each problem in a database is stored with a description and keywords that identify it. It is typically based on cognitive science and artificial intelligence.
