Partitionedįirstly, it’s important to distinguish between sequential and partitioned data sets. Now that it’s clear what a data set is and how it’s different from a database, diving deeper we see that there are a variety of types of data sets that a data analyst must choose from when storing data. Data analysts learn how to work with databases using language such as SQL, which allows them to query and update the data in an organized way. A database provides the structure and the space for a data set to be stored and worked with. In general, data sets need to be stored in a computer system so they can later be accessed, updated and manipulated. While data sets are related to one specific topic, databases hold a greater amount of information about a number of different data sets. Isn’t a database a collection of data? While this is true, typically, databases are much larger and broader than data sets. You may be thinking that a data set is another name for a database. Or they may want to know the range, to know how far the data extends. They might find the mean, or the average, such as the average number of hours of television watched. They also help make sense of an overwhelming amount of numbers and information.ĭata analysts perform a variety of techniques on data sets to extract valuable insights. Why do data sets matter? They make it easier to conduct analysis and perform mathematical operations because when data is in a set, it’s categorized. It would be hard to find a field that didn’t use some type of data set! ![]() Even things like medical or insurance records are data sets. Scientists regularly use data sets to analyze things like climate and research findings. ![]() For example, a shop might use a data set to study their sales and customers, or a multinational company may find a data set useful for analyzing marketing or financial metrics. Data sets are stored with specific names that can be used to retrieve the data at a later time.ĭata sets are put together by data analysts by finding and cleaning the data and then categorizing it into relevant collections that can be used by organizations to measure different metrics. The term data set refers to a collection of data records that are related to each other in some way. If you’re curious about the world of data analytics, you may be wondering what exactly is a data set and what it is used for. Data analytics is changing the world and shows no signs of slowing down.
