Logic Programming in Prolog Lecture 11 Quiz

Overview of Prolog Programs

• A Prolog program can be viewed as a database of facts and rules.

Database Manipulation

• The built-in predicate assert/1 allows adding new clauses to the Prolog database.
• The asserta/1 predicate is used to add a new clause as the first clause for a predicate in the current database.
• The assertz/1 predicate is used to add a new clause as the last clause for a predicate in the current database.
• The five basic database manipulation commands in Prolog are assert/1, asserta/1, assertz/1, retract/1, and retractall/1.
• A Prolog program can manipulate its database during execution by adding, modifying, or removing clauses.

Dynamic Code

• In dynamic code, facts and rules can be added to the database at runtime.
• Dynamic code involves adding facts and rules at runtime in Prolog.

Multiple Databases

• A key requirement for creating multiple databases in Prolog is to use separate predicates for each database.

Importance of Clause Ordering

• When inserting a fact in the database, it is important to consider the ordering of facts because it affects the search order and the execution of the program.

Role of Assert

• assert(Clause) adds a new clause to the database.
• It is important to specify where a clause is asserted in Prolog because it affects the search order and the execution of the program.

Significance of Adding Facts and Rules

• Adding both facts and rules to a Prolog database is significant because it allows the program to reason and draw conclusions based on the data and rules.
