Html. CRUD operations Create, read, update, and delete are the four basic and most common operations for any persistence storage. In this section, we will talk about the process and syntax leveraged by Neo4j to perform all these basic operations. Perform the following steps for creating, searching, and deleting data in the Neo4j database: 1. org/), which provides the creation and execution of the REST calls. 2. Open your tool and execute the following request and parameters for creating data in the Neo4j database: °° Request method type: POST °° Request URL: http://localhost:7474/db/data/transaction °° Request headers: Accept: application/json; charset=UTF-8 and Content-Type: application/json [ 17 ] Your First Query with Neo4j °° JSON-REQUEST: {"statements": [{"statement" : "CREATE (movies:Movie {Name:"Noah", ReleaseYear:"2014"});"}]} °° Additional HTTP header: Authorization = Basic 3.

Properties) from the specified location, and then starts the shell.
