An original array is kept in a database like a frequent string value and it's not feasible to search effectively. RAID 5 arrays are usually regarded as a bad option for use on write-intensive systems due to the performance impact connected with writing parity info.

Sequence objects are extremely useful once you will need to create integer values that are certain to be unique each time you desire a new identifier number to insert a new entry table.
