A data warehouse has multiple functional areas whereby a centralized organizational unit is responsible for implementing it. On the contrary, data marts focus on particular functional areas hence are simple forms of a data warehouse.
The point lies 1 unit below the regression line.
What are the three most common forms of data warehouses? is a smaller form of a data warehouse that is often used by a single department or function. An independent data mart is a tiny warehouse that is built for a strategic business unit (SBU) or a department, but it does not have a central data source (EDW).

A database is a collection of data stored in one unit. It organizes information in a structured format, allowing for efficient storage, retrieval, and management of data for various purposes.
A record is the largest unit of information in the data hierarchy. The smallest unit in the data hierarchy is called a data field.
In a TCP segment, the field used to determine if an arriving data unit exactly matches the data unit sent by the source is the Sequence Number field. This field indicates the position of the first byte of data in the segment, allowing the receiver to check if it received the correct data in the expected order. Additionally, the Acknowledgment Number field can confirm receipt of segments by indicating the next expected byte.
1 MB (megabyte) is a unit of data measurement that equals 1,024 kilobytes or 1,048,576 bytes. It is not a bit; rather, it is a larger unit that represents a collection of bytes, with each byte consisting of 8 bits. Therefore, 1 MB is equivalent to 8,388,608 bits.

Information is stored in data, which is a collection of information. Strictly speaking, a datum (singular form of data) is a single unit of information.
A collection of data by the accurate observation of an object or process using a standard unit. Good enough?
In a database management system (DBMS), a field is a unit of data that represents an attribute of an entity. Fields are used to store specific pieces of information within a database table, such as names, dates, numbers, or other data types. Each field is defined with a specific data type and constraints to ensure data integrity and accuracy.
A collection of data stored in one unit and identified by a file name is referred to as a file. Files can contain various types of information, such as text, images, audio, or structured data, and are typically organized in a file system on a storage medium. Each file is associated with a specific format that determines how its contents are structured and accessed.
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).
