Query execution plans are potentially the most critical aspect of database performance. Improving bad plans is certainly an area where a small amount of effort can bring huge improvements. While hardware issues can limit query performance, improving hardware usually yields performance improvements in the 10-20% range. More commonly, database administrators encounter queries that are not optimised, have stale or missing statistics, have missing indexes, or poor database design choices that lead to the database engine doing more work than is necessary to return results for a given query. Improving the plans can sometimes yield performance improvements in the 100-200% range or even more, meaning that after improving a plan with better indexes or statistics, a query could run twice or three times as fast! This module provides details on how to analyse individual query performance and determine where improvements can be made.
Lessons

- Determine whether a query or design changes have had a positive effect
A common goal for database administrators in many environments is to automate as many of their repetitive tasks. This can be as simple as scripting to automate a backup process and as complex as building a fully automated alerting system.

Data must be available when the business needs it. That means the solutions hosting the data must be designed with availability and recoverability in mind. For example, suppose you work for a company selling widgets in stores and online. Your main application uses a highly transactional database for orders. What would happen if the server or platform hosting the transactional database had a problem that made it unavailable or inaccessible for some reason? What impact would it have on the business? If the right solution is implemented, the database will come online reasonably with minimal effort, thus allowing business to continue with little-to-no impact. This module and its associated lab cover configuring, testing, and managing a solution for high availability and disaster recovery (HADR) in Azure for both Infrastructure-as-a-Service (IaaS) and Platform-as-a-Service (PaaS) deployments. This module will cover basic requirements and the various options available to achieve HADR.
