Choosing the optimal approach may include analyzing the available tools and database capabilities, as well as taking into account performance and security factors.

It is important to note that the function should be written taking into account the best programming practices and generally accepted coding styles. It should be understandable, effective and safe when used in real projects.

In conclusion, the function that returns the number of tables in the database is a valuable tool for database administration and application development. Its implementation requires taking into account the specifics of each database and choosing the right approach.
