Today I'd like to point my readers to an interesting survey being conducted on the usage of referential integrity and database constraints in your database implementations. The survey should take about 5 minutes or so to complete.
It is being conducted by a practicing Database Administrator/Database Developer (18+ years) who is a graduate student in the newly developing science of “Information Quality”. (The world’s first graduate program was started Fall 2006 by the University of Arkansas at Little Rock in collaboration with the Massachusetts Institute of Technology).
The survey is being conducted because of the perception that the implementation of database integrity constraints is deficient in many production databases. The intent of the survey is to discover why this might be so. The results of this survey should be of interest to practitioners and theorists in the areas of relational database development as well Information/Data quality.
The database constraints being referred to include referential integrity constraints, check constraints (or rules) and triggers. To some, triggers may seem odd choice for business rules enforcement. However they offer a rich capability of rule enforcement besides it was also the only choice in certain RDBMs at one time. Questions have skip logic and your answers affect what further questions you are asked.
Confidentiality and anonymity is guaranteed in our survey. No personal information is required to complete the survey. None of the questions in the survey are mandatory. You may quit from the survey at any time by closing the browser window. A copy of the results will be available upon request. This survey is not sponsored by any commercial entity.
