In databases, low-level data consists of ______.

Low-level data refers to the most granular form of data that can be processed within a database. In this context, characters are the basic building blocks of data. They represent individual letters, numbers, symbols, or even whitespace, which can be combined to form higher-level data structures such as strings or words.

Understanding low-level data is essential because it lays the foundation for constructing more complex data types and structures like attributes, records, and tables. When databases are designed and queried, these characters ultimately play a crucial role in the manipulation and retrieval of information. This underlines why recognizing characters as low-level data is vital in the context of data analytics and database management.
