MySQL Workbench is a graphical tool for working with MySQL.
MySQL Workbench provides an easy to use interface for performing the many tasks involved when working with databases. It integrates SQL development, administration, database design, creation and maintenance into one visual integrated development environment.
MySQL Workbench is similar to SQL Server’s SSMS, which is used for administering SQL Server.
An orphaned record is a record whose foreign key value references a non-existent primary key value.
Orphaned records are a concept within database relationships. If a row in a related table references a non-existent row in the primary table, it is said to be an orphaned row. This is because it has no “parent” with which its data is associated with. The terms orphaned row and orphaned record tend to be used interchangeably, even though there’s a subtle difference between a row and a record.
Referential integrity refers to the accuracy and consistency of data within a relationship.
In relationships, data is linked between two or more tables. This is achieved by having the foreign key (in the associated table) reference a primary key value (in the primary – or parent – table). Because of this, we need to ensure that data on both sides of the relationship remain intact.
So, referential integrity requires that, whenever a foreign key value is used it must reference a valid, existing primary key in the parent table.
The term data integrity refers to the accuracy and consistency of data.
When creating databases, attention needs to be given to data integrity and how to maintain it. A good database will enforce data integrity whenever possible.
For example, a user could accidentally try to enter a phone number into a date field. If the system enforces data integrity, it will prevent the user from making these mistakes.
Maintaining data integrity means making sure the data remains intact and unchanged throughout its entire life cycle. This includes the capture of the data, storage, updates, transfers, backups, etc. Every time data is processed there’s a risk that it could get corrupted (whether accidentally or maliciously).
