| | Relational Model: Data Integrity |
 | | The entity integrity rule states that the value of the primary key can never be a null value (a null value is one that has no value and is not the same as a blank). | | | The referential integrity rule states that if a relational table has a foreign key, then every value of the foreign key must either be null or match the values in the relational table in which that foreign key is a primary key. | | | Data integrity means, in part, that you can correctly and consistently navigate and manipulate the tables in the database. |

| | Simply stated data integrity means that the data values in the database are correct and consistent. | | | The referential integrity rule states that every foreign key value must match a primary key value in an associated table. | | | Although not part of the relational model, most database software enforce attribute integrity through the use of domain information. |

| | Maintaining Data Integrity |
| | The semantics of integrity constraints are very clearly defined, so the internal operations that Oracle performs to enforce them are optimized beneath the level of SQL statements in Oracle. | | | If you decide to define referential integrity across the nodes of a distributed database using triggers, then be aware that network failures can limit the accessibility of not only the parent table, but also the child table. | | | In summary, an integrity constraint can be thought of as a statement about the data in a database. |
