This may sound like a simple question, but to answer it, an IT professional has to show they are up to date with the latest trend in cloud computing. There are three types of data necessary to work with the cloud to save and store various data files. First of all, you want the candidate to talk about unstructured data. Unstructured data is data that has an unknown or unclassified structure. You can classify all those file types, such as images, video, text, and search engine results, as unstructured data. After unstructured data, a cloud computing expert should talk about structured data. This type of data is processed, accessed, and stored in a fixed format. An example of structured data is contained in database management systems. Finally, we find semi-structured data, a mix of structured and unstructured data. An excellent example of this type of data in XML format.
