Course Details

This course helps trainees to understand about the various API elements such as Repository, Session and Node. The repository is represented as a repository object and to connect to the repository the specific credentials are required. With the help of session object the trainees will learn how to access or call any node in the workspace. A node can have no parent or one parent as well as can have multiple offspring. The trainees will learn retrieval and transversal of nodes and properties, reading the values of properties and to discover the availability of node types. The prerequisites for this course are basic knowledge of XML and SQL. The course is beneficial for both beginners as well as intermediate to enhance their learning skills and knowledge in API elements.
