Explanation:
database is an organized collection of data, generally stored and accessed electronically from a computer system. Where databases are more complex they are often developed using formal design and modeling techniques.
In computer science and computer programming, a data type or simply type is an attribute of data which tells the compiler or interpreter how the programmer intends to use the data. ... This data type defines the operations that can be done on the data, the meaning of the data, and the way values of that type can be stored.
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.
A record is a data structure that groups together related items of data. These are slightly more complex than arrays as you can store more than one type of data together. ... Creating records will vary in different languages. Python uses a data structure called 'dictionaries' that has some features of the record structure.
