Databases cannot perform at all without data - it is that simple. Data is the lifeblood of databases, and once a database is populated with data, the things a data analyst can do with it are truly remarkable. By harnessing the power of data, modern life has become more efficient in virtually every way. In this course, you will explore the basics of data, beginning with an introduction to data types, structured data, defined rows and columns, and key-value pairs. You will then proceed to explore unstructured data, undefined fields, machine data, and discrete and continuous data. Next, you will dig into categorical data, numerical data, text data, multimedia data. Finally, you will examine text files, HTML files, XML files, and JSON files. This course can be used to prepare for CompTIA Data+ (DA0-001) exam.
