<｜begin▁of▁sentence｜>### Instruction:
As a networkx professional, given a file named 'database.graphdb' in GraphDB format, you would like me to demonstrate how to use the `nx.read_graphdb` function in the networkx library to create a graph object from this file. After reading the file, you would like to print a summary of the graph to gain insights into its structure and properties.
### Response:
import igraph as ig

# Assuming 'database.graphdb' is a GraphDB format file
# Read the GraphDB format file and create a graph
graph = ig.Graph.Read_GraphDB('database.graphdb')

# Print summary of the graph
print(graph.summary())
