Avoid redundant data. Ensure that relationships among attributes are represented. Facilitate the checking of updates for violation of database integrity constraints. Data for branch-name, branch-city, assets are repeated for each loan that a branch makes.

Wastes space. Complicates updating, introducing possibility of inconsistency of assets value. Null values. Cannot store information about a branch if no loans exist.

Review: domain. Domain is atomic if its elements are considered to be indivisible units. Examples of relaional domains: set of names, composite attributes. In relational schema all domains are usually assumed to be atomic 6. First Normal Form. Functional Dependencies. Functional Dependency is a constraint that requires that the value for a certain set of attributes determines uniquely the value for another set of attributes.

A functional dependency is a generalization of the notion of a key. Review: keys. K is a candidate key for R if and only if. Functional dependencies allow us to express constraints that cannot be expressed using superkeys. Use of Functional Dependencies. We use functional dependencies to:. Note: A specific instance of a relation dqtabase may satisfy what is the meaning of immediate effect functional dependency even if the functional dependency does not hold on all legal instances.

Functional Dependencies Cont. A functional dependency is trivial if it is satisfied by all instances of a relation. Closure of a Set of Functional Dependencies. Pitflals a set F of functional dependencies, there are relationak other functional dependencies that are logically implied by F. The set of all functional dependencies logically implied by F pitfals the closure of F.

These rules are. Closure of Functional Dependencies Cont. Look back at our goal: lossless-join decomposition 4 and 2. How do we know that decomposition is a lossless join? A decomposition of R into R1 and R2 is lossless join if and only if. Cerrar sugerencias Buscar Buscar. Configuración de usuario. Saltar el carrusel. Carrusel anterior. Carrusel siguiente.
