well Kevin Kostyszyn, this is true that often we ignore such small issues which sometime impact the performance a lot. ya, it's good if we do inserts and then rebuild the indexes, but generally not done during usual work., since every time u insert records , oracle rebuilds the index itself with every entry (..if i'm not correct pls suggest..)
and thus impact ther performance.
we certainly have an alternative to this situation, where we have Index organised tables..which do not build index on tables rather it stores the table as index.. but has its own ups and down sides..
