- Set of properties that guarantee database transactions are processed reliably. Stands for Atomicity, Consistency, Isolation, Durability.
- Atomicity means that database operations are applied following a “all or nothing” rule. A transaction is either fully applied or not at all.
- Consistency means that each transaction that modifies the database takes it from one consistent state to another.
- Once a transaction is committed, it will remain so.
- Foreign Key
- A referential constraint between two tables. Example: A purchase order in the purchase_orders table must have been made by a customer that exists in the customers table.
- The Isolation requirement means that no transaction can interfere with another.
Jenkins is a continuous integration system that we use to help ensure the continued quality of the software we produce. It helps us achieve the aims of:
- no failed tests in trunk on any platform,
- aid developers in ensuring merge requests build and test on all platforms,
- no known performance regressions (without a damn good explanation).
