The key requirement for success of configuration management is the commitment of all levels of management to enforcing its use throughout the project lifetime. Configuration management, like other parts of software engineering perceived as being tedious, may require some coercion for success. A further requirement is the availability of a clearly stated configuration management plan.
By helping to maintain product integrity, configuration management reduces overall software development costs. Cost savings during a particular phase of the life cycle depend on the depth of application of configuration management. For instance, controlling individual source code modules costs more than only controlling the fully integrated product, but should result in overall savings due to reduction in side effects from individual changes. At this time, however, there are no quantitative measures sufficiently well developed to document the cost savings. This is largely because the […]
SELECT NAME, COUNT (NAME) FROM TABLE1 GROUP BY NAME HAVING COUNT (NAME) > 1
Select into emp1 from EMP where 1=2
Truncate table <Table name> Truncate table EMP Truncate can’t be roll backed and it’s much more faster compare to delete
