Discussion
Logic and reasoning play important roles in computer applications, systems management, database management, and error management. Here, you will examine logic and deductive reasoning, symbols and definitions, and an application involving database and error logging.
Please select ONE of the topics below and begin a conversation about at least ONE of the questions that
follow:
Deductive Reasoning,
Part 1
Consider the following statement: If x1, x2, and x3, then y.
Write this statement as a logical statement using the appropriate logical symbols for conjunction and implication.
Set up the truth table for this statement.
Write the converse and contrapositive of this statement.
Deductive Reasoning, Part 2
Assume you are a systems manager and that you know a server will log an error message if a database has a retrieval error.
Why is it important for errors to be logged?
What is a database retrieval error, and what might cause this type of error?
If you notice that there is an error logged, can you infer that a retrieval error has occurred without reading the log? Explain why or why not. (Hint: This is a question about reasoning.)
