SQL is a useful language for programming, and can be relatively straightforward to learn and understand. It can be used to query databases, data warehouses and day-to-day manipulations. It is an ideal skill to acquire for data analysts, data scientists, data engineers and marketing managers, amongst other roles.
This webinar is aimed at an intermediate level and so attendees should have a working knowledge SQL, and should have knowledge of creating a table, inserting data, querying the table, retrieving data, and aggregating data using SQL.
