Types of data
Today, there are different software tools that allow an efficient approach to data storage and make data management and maintenance simple, however, not all data are equally easy to manage and are classified through three categories, the data structuredthe data unstructured and the data semi-structured.
Structured data are those usually found in databases. These are text-type files that are usually represented by rows and columns with headings and can be easily sorted and processed by any data mining tool. The format, length and size of the structured data are perfectly defined.
Unstructured data is usually binary data that have no identifiable internal structure. It is a disorganized set of several objects that have no value until they are ordered and stored in an organized way. It is possible, but not always, to convert unstructured data into structured data, which is a costly and time-consuming process. Many times, data is stored in a way that makes sorting and categorizing it a difficult task due to incompatibility with a relational database system. For example, pdf texts are unstructured data.
Semi-structured data are those data that have not been previously organized in a database which present associated information such as metadata that makes the task of processing them into structured data easier. They are a form of structured data that do not present the basic structure of the data, but contain labels or other elements that make them identifiable.
