referential integrity การใช้

• It supports all combinations of UML multiplicity and enforces referential integrity.
• Referential integrity is enforced via cascading updates and deletes.
• Tools can enforce referential integrity and perform static checks of the final system before deployment.
• Which method is used may be determined by a referential integrity constraint defined in a data dictionary.
• The software supports referential integrity, multi-master replication, and has a modular authentication architecture.
• Hand-over can be for a part of all data, whilst maintaining full referential integrity.
• This subschema is standard-relational, with features such as constraints and referential integrity being used to the hilt.
• Model-to-model consistency concerns the referential integrity as well as high-level constraints of the system.
• An "'XML schema "'is a description of a type of uniqueness and referential integrity constraints.
• The application model defines entities ( tables ), fields, keys ( indexes ) and relationships together with referential integrity.
• In simple terms,'referential integrity'is a guarantee that the target it'refers'to will be found.
• This includes topics such as referential integrity and entity integrity in a relational database or correctly ignoring impossible sensor data in robotic systems.
• For instance, deleting a record that contains a value referred to by a foreign key in another table would break referential integrity.
• To reference the entity via the natural key, it is necessary to remove the unique constraint making Referential integrity by DBMS impossible.
• This offers a true relational database with referential integrity, scalability, maintainability, and extensibility compared to the SharePoint views Access 2010 used.
• A lack of referential integrity in a database can lead relational databases to return incomplete data, usually with no indication of an error.
• Unlike SharePoint lists, this offers true relational database design with referential integrity, scalability, extensibility and performance one would expect from SQL Server.
• This also results in fewer reads, less referential integrity issues, and a dramatic decrease in the hardware needed to support a given transaction volume.
• This partly a matter of making sure that soft references between models and code are not broken, similar to referential integrity in model-to-model consistency.
• The major advantage of this is that if an entity is renamed, all of the references to it in the program remain valid ( known as referential integrity ).
