MEASURING UNIT IN DATABASE

A database is an organized collection of data. The data are typically organized to model relevant aspects of reality in a way that supports processes requiring this information. For example, modeling the availability of rooms in hotels in a way that supports finding a hotel with vacancies.

Database management systems (DBMSs) are specially designed software applications that interact with the user, other applications, and the database itself to capture and analyze data. A general-purpose DBMS is a software system designed to allow the definition, creation, querying, update, and administration of databases. Well-known DBMSs include MySQL, MariaDB,PostgreSQL, SQLite, Microsoft SQL Server, Oracle, SAP, dBASE, FoxPro, IBM DB2, LibreOffice Base and FileMaker Pro. A database is not generally portable across different DBMSs, but different DBMSs can interoperate by using standards such as SQL and ODBC or JDBC to allow a single application to work with more than one database.

Bytes(8 bits)

• 0.1 bytes: A binary decision
• 1 byte: A single character
• 10 bytes: A single word
• 100 bytes: A telegram OR A punched card

Kilobyte (1000 bytes)

• 1 Kilobyte: 1KB

Megabyte (1 000 000 bytes)

• 1000Kilobyte (KB) = 1Megabyte(MB)

Gigabyte (1 000 000 000 bytes)

• 1000 Megabyte (MB) = 1Gigabyte (GB)

Terabyte (1 000 000 000 000 bytes)

• 1000Gigabyte (GB) = 1 TB

Petabyte (1 000 000 000 000 000 bytes)

• 1000 TB = 1 PB

Exabyte (1 000 000 000 000 000 000 bytes)

• 1000 PT = 1 Exabyte (EB)

Yottabyte (1 000 000 000 000 000 000 000 000 bytes)

• 10000 EB = 1 YB

Xenottabyte (1 000 000 000 000 000 000 000 000 000 bytes)

• 1000 YB = 1 XB

Shilentnobyte (1 000 000 000 000 000 000 000 000 000 000 bytes)

• 1000 XB = 1 SB

Domegemegrottebyte (1 000 000 000 000 000 000 000 000 000 000 000 bytes)

• 1000 SB = 1DM
