CompTIA Data+: Query Optimization

Skillsoft issued completion badges are earned based on viewing the percentage required or receiving a passing score when assessment is required. You have received a large dataset, spent the time and requisite care cleansing and manipulating it to make it the best possible dataset so that you can extract useful information from it. Now what? Well, now you can begin querying the data. But queries can get complicated fast, especially when dealing with massive amounts of data. That’s where query optimization comes in. Queries can be optimized to make your results faster and more meaningful. In this course, you will explore the key concepts of query optimization, beginning with query optimization and typical tools used in query optimization. Then you will conduct parameterized queries, perform index scans, use temporary tables, and use record subsets. Finally, you will dig into execution plans and common best practices for query optimization. This course can be used to prepare for CompTIA Data+ (DA0-001) exam.
