\subsection{Relational diagram}
\paragraph{Description}
\chapter{Task 3 - Relational diagram}
\section{Description}
A relational diagram was generated using SQL developer. The most notable aspects of it are:\\
- Entities remain the same as in the logical diagram, they are now described with higher details written by the generation.\\
\\
\paragraph{Entities descriptions}
How entities changed, from logical diagram:\\
- STADIUM - Nothing of note changed, but now types of attributes and stored relations with other entities are displayed.\\
- COMPETITION - Nothing of note changed, but now types of attributes are displayed.\\
- MANAGER - Nothing of note changed, but now types of attributes and stored relations with other entities are displayed.\\
- CLUB - Nothing of note changed, but now types of attributes and stored relations with other entities are displayed.\\
- MATCH - Nothing of note changed, but now types of attributes and stored relations with other entities are displayed.\\
- PLAYER - Nothing of note changed, but now types of attributes and stored relations with other entities are displayed.\\
\paragraph{Relations descriptions}
How relations changed from logical diagram.\\
- Most of the relations remained visually the same aside from three, those are:\\
- STADIUM:COMPETITION-takes\_place\_in along with CLUB:MATCH-takes\_part\_in have been separated into a relational block based on the fact that those are N:M relations\\
- MANAGER:CLUB-works was disjoined into two relations due to the original relation being 1:1 with identity
