What is a field called in a physical database?

In a physical database, a field is also called a column. It represents a specific piece of data that is stored in a database table, such as a name, age, or address. Each column typically has a data type that defines the kind of data it can hold.


2 reasons why using the correct field type is important?

Using the correct field type ensures accurate data entry and validation, preventing data inconsistencies or errors in the database. It also enhances data processing efficiency as the system can perform operations faster and more accurately with properly defined field types.


A field or a combination of fields that has a unique value is a?

A unique value is a distinct data point that differentiates one record from another in a database. When a field or combination of fields in a database table has a unique value, it means that no other records can have the same value for that particular field or combination of fields, ensuring data integrity and preventing duplication.


What are the consequences of changing a field size?

Changing a field size in a database table can impact existing data integrity, causing data truncation or loss if the new size is smaller. It can also affect queries or application logic that rely on the original field size, potentially leading to errors or inconsistencies. Additionally, altering a field size may require additional system resources or maintenance to accommodate the change.

What is functions of a database management system?

a set of principles concerned with determining which states are valid for a database.Data Integrity within a relational database is that property of a database which ensures that it is and remains an accurate reflection the universe of discourse that it is attempting to model. This includes rules and restrictions to ensure the recording of correct data. It also involves the protection of data within the database. These rules are called integrity constrains.These restrictions are used in almost every field of input to the database.Examples of this is where you are given a drop box on a form to select from a list. This eliminates the chance of multiple spelling of a word. eg. colour color

What is a foreign key field?

A foreign key field is a reference to data in another table. For example, assume that that government has a big list of names and social security numbers (or social insurance numbers, if you live in Canada). They have your SSN/SIN in one field and your name in another field and your address in a third field. Your SSN/SIN is a unique key that can be used to track data associated with you. Suppose now that the government wanted to put data about you in another table. Rather than copy all of your information, they decide that they are just going to put your SSN/SIN number in that other table instead. This is a good move, as they don't have to repeat data. But what if they enter the SSN/SIN incorrectly? That would cause trouble in the database. In order to solve this problem, foreign key fields are used. In the second table, the SSN/SIN field would be a foreign key field, meaning that whenever data is entered into that field, the database management system will automatically look up the data in the main database table to make sure that the SSN/SIN number exists. This allows the database management system to make sure that incorrect data is not added to a database table by mistake.
