Benefits of making system catalog relations?
There are several advantages to storing the system catatlogs as relations. Relational system catalogs take advantage of all of the implementation and management benefits of relational tables: Effective information storage and rich querying capabilities. The choice of what system catalogs to maintain is left to the DBMS implementor.
A relation in which at least one species benefits?
Symbiosis.
What is the relation between the digestive system and the circulatory system?
The relation between the circulatory system and the digestive system is that the digestive system makes energy so the energy goes to the heart and that is what makes it pump.
What information is stored in the system catalogs?
The system catalogs are the place where a relational database management system stores schema metadata, such as information about tables and columns, and internal bookkeeping information. PostgreSQL's system catalogs are regular tables. You can drop and recreate these tables, add columns to them, and insert and update values. However, this can cause severe system damage and data loss. Normally one never has to change the system catalogs by hand; there are always SQL commands to do that. (For example, CREATE DATABASE both inserts a row into the pg_database catalog and creates the database on disk.) However, there are some exceptions for esoteric operations, such as adding index access methods.

How can one derive the dispersion relation for a given physical system?
To derive the dispersion relation for a physical system, one typically starts with the equations that describe the system's behavior, such as wave equations or equations of motion. By analyzing these equations and applying mathematical techniques like Fourier transforms or solving for the system's eigenvalues, one can determine the relationship between the system's frequency and wavevector, known as the dispersion relation. This relation helps understand how waves propagate through the system and how different frequencies and wavelengths are related.
