Don't save the data in table, instead, save it in a file and read it when needed. What are the advantages and disadvantages of this approach?

When considering whether to save data in a file instead of a database table, it's essential to weigh the advantages and disadvantages of each approach. Here's a detailed analysis of both methods:

Advantages of saving data in a file:

1. Simplicity: Saving data in a file is relatively simple, as there's no need to set up a database or write complex queries. This approach is ideal for small projects or applications where data is not expected to grow significantly.
2. Flexibility: Files can be easily accessed and manipulated using various tools and programming languages. This flexibility makes it an attractive option for developers who prefer working with files rather than databases.
3. Cost-effective: Using files to store data can be more cost-effective than using a database, especially for small to medium-sized projects. There are no licensing fees or ongoing maintenance costs associated with file storage.
4. Customizability: Developers have complete control over the file format and structure, allowing them to tailor the data storage solution to their specific needs.

Disadvantages of saving data in a file:

1. Limited scalability: Files have limited scalability compared to databases. As the amount of data grows, managing and accessing it from files can become increasingly complex and time-consuming.
2. Lack of data consistency: When data is stored in files, there's a risk of inconsistencies arising due to concurrent access or updates. This can lead to data corruption or loss.
3. Limited querying capabilities: Files do not offer the same level of querying capabilities as databases. Developers must write custom code to extract and manipulate data from files, which can be time-consuming and error-prone.
4. Lack of data security: Files are not as secure as databases, as they can be easily accessed and modified by unauthorized users. This can lead to data breaches and other security issues.
5. Limited transaction support: Files do not support transactions, which can make it difficult to maintain data integrity when multiple updates are required.

In conclusion, saving data in a file instead of a database table has its advantages and disadvantages. The approach is ideal for small projects, where data is not expected to grow significantly, and developers prefer working with files. However, for larger projects or applications where data consistency, security, and scalability are essential, using a database is the better option.
