Depending upon what key field(s) have been defined, the data is ordered according to the basic character and/or numerical sequence (the former of which is almost always per the ASCII code chart concatenation sequence.)

a collection of integrated and related data.
Data hierarchy is the structure and organization of data, which involves fields, records, and files. (c) Bidgoly MIS2.
Data in the database is very easy to handle. To organize data in database in ascending or descending order we can use group by command.
The seven levels of data hierarchy, in order, are: Bit - The smallest unit of data, representing a binary value of 0 or 1. Byte - A collection of 8 bits, often used to represent a single character in computing. Field - A single piece of data or attribute, such as a name or date, within a record. Record - A collection of related fields that represents a single entity, like a customer or transaction. File - A collection of related records stored together, such as all customer records in a database. Database - An organized collection of multiple files that can be accessed and managed efficiently. Database Management System (DBMS) - A software system that enables the creation, manipulation, and administration of databases. This hierarchy illustrates how data is structured and organized from the most basic unit (bit) to complex systems (DBMS).

Data abstraction is the reduction of a body of data to a simplified representation of the whole. Data abstraction is usually the first step in database design in order to create a simplified framework that can be added to in order to complete the database.
Anomalies is the data within the database it is the copy of the original data it needs to be updated in order to avoid problems such as viewing the website.
A database contains data (logically linked) in order to create coherent information. A database could be a stock of paper, a portfolio, or any kind of electronic or physic data stocked together. Adobe Reader displays and print PDF files in order to access a kind of data (stocked in PDF format). The answer is no, adobe reader is a tool for reading documents, a database is a "data stock"
A record is the largest unit of information in the data hierarchy. The smallest unit in the data hierarchy is called a data field.

A database is a collection of data. Data represents items that are stored within the database.
