A multiline LTE inversion using PCA

A multiline LTE inversion using PCA. Marian Martínez González. E. In astrophysics we can not directly measure the physical properties of the objects, we do always retrieve them. We are always dealing with inversion problems.

Integrity Constraints

Integrity Constraints. An important functionality of a DBMS is to enable the specification of integrity constraints and to enforce them. Knowledge of integrity constraints is also useful for query optimization. Examples of constraints: keys, superkeys foreign keys
