GitHub Repository

ocelation experiments with generating object-centric event data from relational databases by combining graph decomposition and sequence construction.

What it does

• Parses SQL DDL into table/relationship metadata.
• Builds directed graph views of schema dependencies.
• Runs community-detection analyses to partition schemas into meaningful subgraphs.
• Produces sequence and join-generation artifacts for creating merged event-log tables.

How it is built

• clustering_utils and cluster/analyser modules evaluate multiple NetworkX community algorithms.
• sequence utilities build spanning-tree-based merge sequences over expanded communities.
• join/merge.py generates SQL join statements and resolves naming collisions.
• Notebooks capture exploratory runs, visualization, and prompt-driven LLM experiments.

Tech stack

Python, NetworkX, cdlib, matplotlib, Jupyter notebooks, SQL/DDL parsing.
