Data Structures and Algorithms Chapter 8 General Trees Basics • Agraphisasetofnodesandasetofedges. • Formally, a graph G = (V, E), where V is a set of nodes (or vertices) and E is a set of edges. • Each edge connects two nodes, and is represented as (u, v), where u and v are nodes. • A […]
Data Structures and Algorithms Chapter 9 Priority Queues • Each element in a queue is associated with a key. • When an element is removed, an element with a minimal (or maximal) key is removed. • Usually keys are numbers. • Objects can be used as keys as far as there is a total ordering

CS W186 Spring 2020 Recovery 1 Motivation In prior modules we discussed the ACID properties of transactions. In this note we will discuss how to make our database resilient to failures. The two ACID properties that we will learn how to enforce in this note are: 2 1. Durability: If a transaction finishes (commits), we
