Properties of different architectures

Software architectures are the blueprint of a software system. They consist of all components involved in a system, relations between various components, the environment of operation, and the principle used in designing the software. In other words, software architecture shows the organization of different software structures and helps understand their behavior.

CSC 472 Introduction to Database Systems Project

Consider the Least Recently Used (LRU) page replacement policy.

Assume that there are only 4 page slots available in the buffer pool.
