-    Amazon Neptune is a fully managed graph 
-    database service by AWS, designed specifically
-    for handling complex relationships and connected 
-    datasets at scale. It supports two popular graph models: 
-    property graphs (via openCypher and Gremlin) and RDF 
-    graphs (via SPARQL). This makes Neptune ideal for 
-    use cases such as knowledge graphs, fraud detection, 
-    social networking, recommendation engines, and 
-    network management, where relationships between 
-    entities are central to the data.

-    Being fully managed, Neptune handles database 
-    provisioning, patching, backups, and replication, 
-    while also offering high availability and durability 
-    within AWS's infrastructure.
-                    
-    For developers, programming with Neptune allows 
-    for building intelligent, relationship-aware 
-    applications that go beyond traditional tabular 
-    databases. Developers can use the AWS SDK for Kotlin
-    to automate infrastructure operations 
-    (via NeptuneClient).
