Constraint may refer to:

Constraint (computer-aided design)
A constraint in computer-aided design (CAD) software is a limitation or restriction imposed by a designer or an engineer upon geometric properties of an entity of a design model that maintains its structure as the model is manipulated. These prop ...
, a demarcation of geometrical characteristics between two or more entities or solid modeling bodies
*
Constraint (mathematics)
In mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. There are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. The set of can ...
, a condition of an optimization problem that the solution must satisfy
*
Constraint (classical mechanics)
In classical mechanics, a constraint on a system is a parameter that the system must obey. For example, a box sliding down a slope must remain on the slope. There are two different types of constraints: holonomic and non-holonomic.
Types of co ...
, a relation between coordinates and momenta

Constraint (information theory) Constraint in information theory is the degree of statistical dependence between or among variables.
Garner Garner W R (1962). ''Uncertainty and Structure as Psychological Concepts'', John Wiley & Sons, New York. provides a thorough discussion of v ...

Constraint (database)
A relational database is a (most commonly digital) database based on the relational model of data, as proposed by E. F. Codd in 1970. A system used to maintain relational databases is a relational database management system (RDBMS). Many relati ...

Biological constraints Biological constraints are factors which make populations resistant to evolutionary change. One proposed definition of constraint is "A property of a trait that, although possibly adaptive in the environment in which it originally evolved, acts to p ...
