Study Notes
Graph Database Fundamentals
- The two main elements in a graph are nodes and relationships.
- In a graph database, data is stored in nodes as key-value pairs called properties.
Graph Database Components
- Relationships between nodes are used to establish connections and define the structure of the data.
- Labels in a graph database serve as a categorization or tagging system, allowing nodes to be grouped and filtered.
Neo4j Specifics
- Storing data in Neo4j is similar to adding records in other databases, with each piece of data represented as a node or relationship.
- Labels in Neo4j are used to define the type or class of a node, enabling filtering and querying.
- Relationships between nodes in Neo4j are represented as directed, named, and typed connections.
- Properties in nodes hold the actual data, with each property consisting of a key-value pair.
Comparing Graph Databases
- A graph database differs from a relational database management system (RDBMS) in its ability to efficiently store and query complex relationships between data entities.
- Graph databases are distinguished from other NoSQL databases by their optimized storage and querying of complex, interconnected data.
