Provide a condensed explanation of the three primary stages that comprise the physical design process. The administration of database recovery can be accomplished with any one of these three backup levels. What exactly is the purpose of having many tiers of data backup?

I would appreciate it if you could list and quickly explain each of the three processes that went into the physical design.When executing duties related to database recovery management, you are free to use these three backup levels in any combination you see fit. What precisely is the purpose of each additional level of backups that is performed?

What does a stable database state include, and how is it attained? The DBMS does not ensure that the transaction's symbolic meaning accurately reflects the underlying real-world event. What effects might such a limitation have? Give an instance. What does the term "serializable transactions" really mean?

In a nutshell, describe the three physical design processes.The administration of database recoveries might use all three of these backup levels. To what end do we have backup levels?

What is a stable database state, and how do you get one? There is no assurance that the database management system's representation of the transaction's underlying actual occurrence corresponds to its symbolic meaning. What consequences would such a restriction have? Give an example to illustrate what you mean. Does "serializable transactions" imply what it seems to mean?

Vendors of RDBMSs agree that RDBMSS not currently suited to advanced database applications, and added functionality is required. C. Vendors of RDBMSs reject claim that extended RDBMSS will not provide sufficient functionality or will be too slow to cope adequately with new complexity. D. Vendors of RDBMSs claim that they can remedy shortcomings of relational model by extending model with OO features. A) B) D)
