I have a simple relational database that has two tables: employees and projects. The employees table has columns for employee_id, name, department, and manager_id. The projects table has columns for project_id, name, and employee_id (the employee who is responsible for the project).

What are the steps to follow to migrate this data to a graph database using Apache AGE?

Migrating relational database to a graph database involes following steps:

First Transform your tabular data to graph format where nodes represent entities and edges represent relationship between them.

Identify your entities and relationship in data model. The entities are employee and projects and relationship are employee to department, employe to project and employee to manager.

Design Graph Schema it is a blueprint that defines structure of graph database.

For creating Node's you can run:

SELECT * FROM cypher('your_graph_name', $$ CREATE (n:Employee {name : "EmployeName", department : "DepartmentName"}) $$) AS (a agtype);
