What is the difference between a field and a record?
Fields and records are two basic components of a database, which is an organized collection of information, or data. The term “fields” refers to columns, or vertical categories of data while the term “records” refers to rows, or horizontal groupings of unique field data.
What is the relationship between a field and a record?
The term “fields” refers to columns, or vertical categories of data; the term “records” refers to rows, or horizontal groupings of unique field data. Examples of both database components are seen in older, printed databases and also in modern, computer-based databases.
Is MySQL a server?
The MySQL Database Software is a client/server system that consists of a multithreaded SQL server that supports different back ends, several different client programs and libraries, administrative tools, and a wide range of application programming interfaces (APIs).
What is the purpose of the data type property for a field?
The Data Type property determines what field values you can enter into the field and what other properties the field will have.
What is an example of a field within a database record?
In computer science, data that has several parts, known as a record, can be divided into fields. Relational databases arrange data as sets of database records, so called rows. Each record consists of several fields; the fields of all records form the columns. Examples of fields: name, gender, hair colour.
What is field name?

Which set is a field?
Formally, a field is a set F together with two binary operations on F called addition and multiplication. A binary operation on F is a mapping F × F → F, that is, a correspondence that associates with each ordered pair of elements of F a uniquely determined element of F.

Is Za a field?
The lack of zero divisors in the integers (last property in the table) means that the commutative ring ℤ is an integral domain. The lack of multiplicative inverses, which is equivalent to the fact that ℤ is not closed under division, means that ℤ is not a field.
