Quizplus · Accepted Answer

Complex modifications to a database structure may require reloading of the data after the changes have been made. Reloading involves importing the data into the modified database structure. Testing is important to ensure that the changes have been implemented successfully, but it is not a requirement for reloading. Deleting data is not necessary unless there has been an error in the data. Indexing is a technique used to optimize the performance of a database and is not related to complex modifications of the database structure.
