Data Management is a general term covering a very large range of data applications. It refers to some basic data management concepts or some specific technologies.
Some of its notable applications include 1) data design, 2) data storage, and 3) data security.
1. Data design, or data architecture, refers to how data should be structured.
For example, when you create a file format for an application, the developer has to decide how to organize the data into a file.
In some applications, data is stored in text format, while in other programs, you may also need binary file format. It does not depend on which format the developer is using. In contrast, the data has to be organized in a file within a structure identified by the associated program.
2. Data storage refers to all how data is stored. It comes under hard drives, flash memory, optical media, and temporary RAM storage.
When you choose the right data storage medium, some concepts like data access and data integrity must be considered.
For example, access and modified data are stored regularly on a hard drive or in Flash Media. This is because this type of media provides quick access and allows the data to move and change.
You can store archived data in optical media such as CDs and DVDs, as there is no need to change these data. Optical discs also maintain data integrity compared to longer-time hard drives, making them a better option for archival purposes.
3. Protecting computer data comes under data security. Many individuals and businesses store their valuable data in computer systems.
If you have stored some very important data on your computer, you probably know how important this data has. So it is very important that you also take such steps to protect the privacy and integrity of your data.
Some steps like installing a firewall that prevents unauthorized access from reaching your computer. At the same time, it encrypts the personal data that you submit or share online with other users.
At the same time, it is also important that you backup your data so that you can recover them again when your primary storage device fails.
