The correct answer is C. increased security.
A database is a collection of data that is organized so that it can be easily accessed, managed, and updated. The database approach has several advantages over traditional file-based systems, including:
- Elimination of data redundancy: In a database, each piece of data is stored only once, in a single location. This eliminates the need to update multiple copies of the data, which can lead to errors and inconsistencies.
- Ability to associate related data: A database can store data about multiple related entities, such as customers, products, and orders. This allows users to easily access and analyze data from multiple sources.
- Increased security: A database can be secured with passwords and other security measures to prevent unauthorized access to data.
- Program/data independence: The data in a database is stored separately from the programs that access it. This means that changes to the data do not require changes to the programs, and vice versa.
Increased security is not an advantage of the database approach. In fact, databases can be more vulnerable to security breaches than traditional file-based systems. This is because databases typically contain more sensitive data, such as financial information and customer records. Additionally, databases are often accessed by multiple users, which can increase the risk of unauthorized access.
To protect data in a database, it is important to implement strong security measures, such as using passwords and encryption. Additionally, it is important to regularly monitor the database for signs of unauthorized access.
