Study Notes

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.
