You asked: What is a constraint in AutoCAD?

Constraints are rules that are applied to 2D geometry. By applying constraints, you can control the location, size, distance, angle, and other parameters of objects in a drawing. As a result, you can identify and maintain specifications in a project.

SQL constraints are a set of rules implemented on tables in relational databases to dictate what data can be inserted, updated or deleted in its tables. This is done to ensure the accuracy and the reliability of information stored in the table.

What are the constraints computer?

Constraint programming (CP) is a paradigm for solving combinatorial problems that draws on a wide range of techniques from artificial intelligence, computer science, and operations research. In constraint programming, users declaratively state the constraints on the feasible solutions for a set of decision variables.
