OLTP has also been used to refer to processing in which the system responds immediately to user requests .The main emphasis for OLTP systems is put on very fast query processing, maintaining data integrity in multi-access environments and an effectiveness measured by number of transactions per second.
Enantiomers is a term that refers to the two molecules that are mirror images of one another but demonstrate chirality of the inability to be superimposed on one another. socratic Subjects
From Wikipedia, the free encyclopedia. Diastereomers (also called diastereoisomers) are stereoisomers which are not enantiomers. They are molecules which have the same atoms and bonds but different stereochemistry in at least one, but not all, of their chiral centres. Diastereomers can have very different properties even though they look similar. This is different from enantiomers, that have exactly the same properties except when in a chiral environment like the human body. Every chiral centre in a molecule has two possible ways of putting the groups in space. With only one chiral centre, there are two enantiomers.
