Naming conventions, which are often overlooked because they do not seem to be important, do not become an issue until they are not implemented.
A lack of naming conventions causes developers to spend their valuable time trying to debug and maintain the application code.

Below are the common naming conventions:

1. Use a naming convention to avoid ambiguity in the code.
   
2. Avoid using the same name for the database column and variables in your code.
   
3. Adopt a naming convention for various objects such as the following example: Using v_ as a prefix representing a variable and g_ as a prefix representing a global variable avoids naming conflicts with database objects.
   vg_petname VARCHAR2(30);

It is important to create and follow naming conventions.
Standards provide a common language for everyone in the team to understand and maintain the code easily.
