# Create database

# Use the database
with db.session() as session:

# Close explicitly (optional - closes on garbage collection)

# Database as context manager
with grafeo.Database(path="my_graph.db") as db:
    with db.session() as session:
        session.execute("INSERT (:Person {name: 'Alice'})")
# Database is automatically closed

# Create multiple sessions for concurrent access

# Each session has its own transaction context
session1.execute("INSERT (:Person {name: 'Alice'})")
session2.execute("INSERT (:Person {name: 'Bob'})")

session1.close()
