There are many NoSQL databases that can be categorized as graph databases, such as ArangoDB, OrientDB, AWS Neptune and the above-mentioned Neo4j. Here we want to differentiate between native and non-native graph databases. Non-native means that the database is actually a relational database that is optimized for graphs [3] - but the native graph databases actually store the data as a graph.
We want to focus on Neo4j as the market leader among the representatives of native graph databases. Neo4j is a Java implementation of the graph database that fulfills all ACID properties and persians the data as a so-called label property graph. This means bangladesh telegram screening that, apart from the fact that data is stored as nodes and edges, these nodes and edges are marked with labels that express what type of entities they represent. Nodes can have any number of labels. Furthermore, nodes and edges can have attributes.
Like most common applications, the Neo4j database can be deployed standalone or in a container, and the enterprise version supports common features such as metric and health endpoints, as well as clustering. To better understand how to use this database, we will use an example to transfer data from a relational database into a graph (Fig. 2).
We usually want to store entities as nodes, so we translate each row of the Person table into a node labeled as Person. We translate each non-foreign key column of the Person table into an attribute of the corresponding node labeled as Person. Finally, we store each foreign key relationship between two entities as an edge between the corresponding nodes.
