Metadata (or metainformation) is "data that provides information about other data",[1] but not the content of the data, such as the text of a message or the image itself.[2] There are many distinct types of metadata, including:

Descriptive metadata – the descriptive information about a resource. It is used for discovery and identification. It includes elements such as title, abstract, author, and keywords.

Structural metadata – metadata about containers of data and indicates how compound objects are put together, for example, how pages are ordered to form chapters. It describes the types, versions, relationships, and other characteristics of digital materials.[3]

Administrative metadata[4] – the information to help manage a resource, like resource type, permissions, and when and how it was created.[5]

Reference metadata – the information about the contents and quality of statistical data.

Statistical metadata[6] – also called process data, may describe processes that collect, process, or produce statistical data.[7]

Legal metadata – provides information about the creator, copyright holder, and public licensing, if provided.

Metadata is not strictly bound to one of these categories, as it can describe a piece of data in many other ways.

Data is collected in tables of fields. The fields (represented as columns) are known as attributes. The fields represent common types of descriptors for each instance. Each instance is represented by a row or record. Tables are considered entities where similar or like information is grouped in rows and columns.

A database is a collection of tables comprised of fields.

Each table represents items that have similar types of information, like Student, Faculty, Course, or Inventory. The items in a table have the same type of descriptors that identify them, but the values of the descriptors can be unique for each item. These are fields.
