How?

1) By moving the transaction management from the application or middleware to the Gnosis Transaction Manager layer on the database. The Gnosis Transaction Manager allows a transactions' work-in-progress to be stored as the users work which significantly reduces work-in-progress vulnerability to system crashes & bugs. The Gnosis Transaction Manager capabilities include stop, start, rollback, commit, create save point, view at save point and rollback to save point functionality as well as the ability to pass a transaction (work-in-progress) from one user to another.

2) By moving the business rules from the application or middleware and to the Business Rule Manager of Gnosis Transaction Manager, which resides on the SQL-Server database. The Business Rule Manager offers many enhancements over standard relational database constraints, such as the ability to define specific error messages for user comprehensibility, to define business rules on views as well as tables, to define whether a rule is enforced as the user works (known as 'on activity') or when the user completes the transaction (known as 'on commit'). The Business Rule Manager also includes the ability to define class hierarchies, mandatory children for a parent, rules on combinations of attributes and more..
