The advantage of storing data as a code is that if you had to write it there would be more spelling mistakes and errors.

data is saved by storing
Dis Advantages: Security may be compromised without good controls, Extra hardware may be required, System is likely to be complex Advantages: Reduced data redundancy, Secured data, Integrated data, Controlled data inconsistency
Proccessing, mostly every program is run using it.
information communication technology
There are eleven operations for data of processing. The eleven data of processing operations in a computer are recording, verifying, duplicating, classifying, sorting, calculating, summarizing and reporting, merging, storing, retrieving, and feedback.
Advantages: CDs are inexpensive, portable, and easily accessible for storing data. They also have a long lifespan if stored properly. Disadvantages: CDs have limited storage capacity compared to other storage mediums, are susceptible to scratching or damage, and may become obsolete as newer technologies emerge.
Hence
data is saved by storing
Advantages to database approach to storing includes everything is in the same place, you can store data tightly and employees can easily retrieve the information. When everything is stored somewhere else, it takes too long to retrieve the information.
Database is used for storing data that are related. We need database in every field for storing data.
Holographic data storage DVD disks are capable of storing data upto 1 TB which is 1500 times then CD and 200 times Single Side DVD.
keeping data in a password-protected database, storing images in a secured cabinet, and coding data or specimens and keeping the key to the code in a separate, locked drawer.
Relational databases provide support for complex queries and relationships between data tables, which is not easily achieved when using a list data structure. Additionally, relational databases offer features like data integrity constraints (such as unique keys and foreign keys) that help ensure data consistency and accuracy. Scalability and performance can also be better managed in a relational database compared to using a list for storing data.
Advantages of storing data in computer files over the manual filing system Stored information takes up less space. Easier to update and modify. Provides faster access and retrieval of data. Reduces duplication of data or stored records. Cheaper. Enhances data integrity (i.e. accuracy and completeness)
XML is becoming the defacto method for transferring data between applications and systems. The main advantages to creating a data backup or extract using XML are 1) because the data fiends are enclosed in tags, it is self-documenting; 2) data validation rules can be included with the files and 3) there is no export/import issues between applications.
Data Drive A data drive is a disk drive that is dedicated to storing data, as opposed to parity, Hamming code, or a hot standby. In RAID levels where the data and parity move around, the space equivalent of this many drives is available to store data.
The advantages are Data Encapsulation Data Hiding Easy to maintain the code Reuseability of classes And disadvantages are wastage of time in case of small projects or codes
