Querying Relational Databases

سرفصل های دوره

About this Course

Building off of previous SQL courses, this course will begin to introduce the student to more complex database concepts. Students will learn to think about data as sets and subsets and practice achieving desired query results via such operations as inner and outer joins, unions and except. They will also be introduced to the concepts of Set Theory and Database Normalization to aid in understanding good query practices.
