Working with Hierarchical File StructuresRead and Write an XML file, configure the schema and XPath expression to parse an XML fileRead and Write a JSON file, configure the schema and JSONPath expression to parse a JSON fileRead and write delimited, fixed width files.8. Context Variables and Global VariablesCreate context/global variablesUse context/global variables in the configuration of Talend componentsLoad context variables from a flow9. Best practicesWorking with databases and implementing data warehousing conceptsWorking with files (excel, delimited, JSON, XML etc.)10. Orchestration and Controlling Execution FlowFiles - Use components to list, archive, and delete files from a directoryDatabase - Controlling Commit and RollbackCOMMIT at end of job/ every x number of rowsRollback on error11. Shared DB connection across jobs and subjobsUse triggers to connect components and subJobsOrchestrate several jobs in master jobs. Handling ErrorsKill a Job on a component errorImplement a specific Job execution path on a component errorConfigure the log level in the console
