+
+
+This is an offical dataset of the paper **RDB2G-Bench: A Comprehensive Benchmark for Automatic Graph Modeling of Relational Databases.**
+
+RDB2G-Bench is a toolkit for benchmarking graph-based analysis and prediction tasks by converting relational database data into graphs.
+
+Our code is available at [GitHub](https://github.com/chlehdwon/RDB2G-Bench).
+
+## Overview
+
+RDB2G-Bench provides comprehensive performance evaluation data for graph neural network models applied to relational database tasks. The dataset contains extensive experiments across multiple graph configurations and architectures.
+
+## Dataset Summary
+
+Each CSV file contains experimental results with the following columns: 
+
+| Column | Description |
+|--------|-------------|
+| `idx` | Unique identifier for each experimental configuration |
+| `graph` | Binary-encoded string representing the graph structure configuration (e.g., "graph_00000000000010") |
+| `train_metric` | Performance metric on the training set (e.g., AUC for classification, MSE for regression, MAP for recommendation) |
+| `valid_metric` | Performance metric on the validation set |
+| `test_metric` | Performance metric on the test set |
+| `params` | Total number of trainable parameters in the model |
+| `train_time` | Training time in seconds |
+| `valid_time` | Validation time in seconds |
+| `test_time` | Testing time in seconds |
+| `dataset` | Name of the RDB dataset used (e.g., "rel-avito", "rel-f1") |
+| `task` | Name of the prediction task (e.g., "ad-ctr", "user-clicks") |
+| `seed` | Random seed for reproducibility |
+
+### Graph Column Specification
+
+The `graph` column uses binary encoding to represent different edge configurations in the graph structure. Each bit position corresponds to a specific edge type as defined in `edge_info.json`:
+
+- **1**: Edge is connected
+- **0**: Edge is disconnected
+
+#### Edge Types:
+- **r2e**: Converted relationships that each row of table trasnsformed to edge.
+- **f2p**: Standard foreign key relationships that each row trasnsformed to node.
+
+The complete edge mapping for each dataset can be found in the `edge_info.json` file.
