What is the Difference Between Modify and Change?

The main difference between "modify" and "change" lies in the extent and purpose of the alteration. Both terms refer to altering something, but they are used in different contexts:

• Modify: This term implies making small changes or slight adjustments to something to improve it, adapt it to a specific situation, or correct a flaw. Modify is more formal than change and suggests making something more suitable for a particular situation. For example, modifying a design or adjusting a plan.
• Change: This term is more general and describes any act of making something different. Change can refer to altering the true nature of something, transforming it into something completely new, or substituting it with another. For example, changing one's opinion, changing a habit, or changing the entire structure of something.

In summary, while both modify and change involve altering something, modify is used to describe slight adjustments or improvements, whereas change is used to describe more significant transformations or replacements.

Comparative Table: Modify vs Change

Both "modify" and "change" are used to alter the structure of a table, such as adding, removing, or modifying columns. However, they are typically used with the ALTER TABLE command to achieve their intended purpose.

Here is a summary of their differences:

Both "modify" and "change" can be used interchangeably when altering a column, but "change" is specifically useful for renaming a column in addition to altering it.
