Description: Hard coding refers to values that are written directly into the code instead of being stored in a variable or external source. This approach means that the data is fixed and cannot be modified without changing the source code. In the context of programming and database interactions, hard coding can manifest in queries where literal values are used instead of parameters or variables. This can lead to maintenance and scalability issues, as any change in the data would require a modification of the code. Additionally, the use of hard coding can increase the risk of errors, as values may be difficult to trace and update. On the other hand, hard coding can be useful in situations where values are constant and not expected to change, simplifying the logic of the code. However, in most cases, it is recommended to avoid hard coding in favor of more dynamic and flexible approaches that facilitate long-term software management and maintenance.
