9. The computer program product of claim 6 , wherein the program instructions are further executable by a processor to cause the processor to: monitor the current job to determine when a new input is made in the current job in the ETL system and iterating for each new input.
6. A computer program product for extract transform load (ETL) input suggestion for an ETL system in which a current job is being created, the computer program product comprising a non-transitory computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to: determine when a new input is made in the current job in the ETL system and dynamically receiving the new input, the new input a new stage input a new stage input; update stored information relating to the current job with the new input; access rules which apply to the current job, the rules including next stage rules; analyze and applying the rules based on the new input and the current job stored information to generate one or more suggested next inputs in the current job, the one or more suggested next inputs including suggested next stages; provide a weighting for the one or more suggested next inputs based on the analysis and application of the rules; and provide a prompt in the current job in the ETL system with the suggested one or more next inputs and their weightings, wherein in response to the new input being the new stage input: the next stage rules are static rules include dynamic rules including: built-in patterns of existing stages in the current job; and dynamic patterns based on previous usage of stages in job designs within the current job environment.
