Answer:
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.
Answer:
Functional requirements usually define if/then behaviours and include calculations, data input, and business processes. Functional requirements are features that allow the system to function as it was intended. Put another way, if the functional requirements are not met, the system will not work.
Explanation:
Answer:
B. Run-time Error
Explanation:
You can't divide by zero in math because it could be divided by itself an infinite number of time, which is not possible.
A. Syntax error is just the 'grammar' of the code. An example could be forgetting to add a semicolon at the end of your code in C. Another example is forgetting to close brackets or quotes
<em>printf("inclomplete string </em>WRONG, will give syntax error
B. Run-time error is an error that occurs while the program is running. This might happen because of many reasons, one of which is calculation errors such as dividing by 0.
C. I don't know what an Undetected Error is. Never hear of it.
D. Logic error is an error when a condition is not logically correct. This could be because you used the wrong type of operator.
if(a = b) WRONG, will give logic error
if(a == b) CORRECT
