Data file prepared offline - Not connected to cloud instance	Excel sheet connected to the instance - Similar to WebADI in EBS	Web based APIs that can be accessed by heterogeneous systems
Validation is done after full upload	Excel validation via list of values	Validation after making the web service call
Requires moderate technical expertise	Very user friendly	Highly technical
Extensive data preparation effort	Less effort in preparing excel data	Less effort in preparing data for desired tags in API calls
Very fast upload	Slower upload compared to FBDI	Considerably slower due to row-by-row operations
No plugins required	Works via desktop Excel plugin	Custom integration processes to invoke inbound/outbound SOAP/REST APIs
Bulk load via CSV files	Data upload directly from Excel	Custom integration processes to invoke inbound/outbound SOAP/REST APIs
