The training comes as a part of, or separate from, the MS Office training course. If the user thinks that he wants to learn every aspect of MS Office, then he can go for the entire Microsoft Office course. But if he wants to learn only MS Access, then the particular course may be taken alone.
Going through a Microsoft Access training program is certainly beneficial to everyone, whether for a long-time Access user or a beginner. Undergoing the training will help keep you abreast with the developments, newest features and latest techniques in using MS Access.
