Imagine there is a database management system that is always online. In this particular system, is there a need for the recovery manager? Why?

I need help answering a few HW questions..... a. Name the different types of recovery and discuss the factors that influence when each type of recovery should be performed? b. Name and describe the three types of database failures that may require recovery? c. What is meant by the term log archival, and why is it important to assure recoverability? So I wasnt able to answer them completely, but I was able to answer these partially (Can someone help fill in my answers)?........... Recovery to Current Point-in-Time (PiT) Recovery Transaction Recovery   ==================================================================== Instance Failures: Application Failures: Media Failures: ==================================================================== Long Archival indicates.....

Take the following scenario into consideration: Is it necessary to have a recovery manager for the database system that operates perfectly all the time, and if so, why is it necessary?

What is the use of the LDAP standard if it can simply be placed on top of an existing database system?

Consider the possibility that your database management system is the source of the issue. Have you worked with databases before? Do you have any experience with the write-through and deferred-write recovery approaches?

Consider the possibility of an unbreakable database system. Is a recovery manager required for this infrastructure, and if so, why?
