The variety of data in the database makes it necessary to classify them by type, depending on what information is stored in this field
The use of data is a problem in programming and developing information systems. Before analyzing a “large amount” of data and making a decision that guarantees a reliable and objective result, it is necessary to determine this “large amount”.
