The data type of a field determines the kind of data it can contain. For example, a field with a data type of "Text" can contain letters and numbers, while a field with a data type of "Number" can only contain numerical values. The data type is set when designing the database schema.

In network data model , the records are related to each other by means of a link. A record is collection of fields , each of which contains only one data.

Some fields that store only numbers may use a text data type to accommodate specific formats, such as leading zeros or special characters (e.g., phone numbers, ZIP codes) that should not be mathematically manipulated. Additionally, using a text data type can allow for greater flexibility in data entry and prevent unintentional calculations. This approach ensures that the data is stored exactly as intended, preserving its meaning and context.
The problems associated with redundant data can be addressed by data normalization. Normalized tables generally can contain no redundant data because each attribute only appears in one table. Also, normalized tables do not contain derived data and instead, the data contained can be computed from existing attributes which has been selected as an expression based on the said attributes.
Logical file is a type of file that provides a view of the data stored into the Physical file. It does not contain data. A logical file contains only an index to the data stored into the physical file.
No. Gamma rays are light, and the only thing that can "hold" light is the "inside" of a black hole's event horizon.
