3. What is a key difference between databases and Excel spreadsheets in terms of scalability and performance?

1 answer

A key difference between databases and Excel spreadsheets in terms of scalability and performance is that databases are designed to handle large volumes of data and concurrent multi-user access more efficiently than Excel spreadsheets.

Scalability:

  • Databases: Can manage vast amounts of data (millions or even billions of records) without significant degradation in performance. They can handle rich data relationships and complex queries, making them suitable for large-scale applications.
  • Excel Spreadsheets: Have a limit on the number of rows and columns (Excel has a maximum of 1,048,576 rows and 16,384 columns) and can become sluggish or unresponsive with large datasets. They are mainly designed for smaller datasets and individual use.

Performance:

  • Databases: Are optimized for speed and efficiency when retrieving, updating, and managing data. They utilize indexing and optimized query execution plans, enabling them to process queries quickly, even with extensive data.
  • Excel Spreadsheets: Can experience performance issues such as slow calculations and lagging as the complexity and size of the data increase. Calculations in Excel may be less efficient and are often limited by the processing power of the user's machine.

In summary, databases offer greater scalability and better performance for handling large datasets and multi-user scenarios, while Excel is better suited for simpler, smaller-scale data analysis and individual use.
