Hi,
Vikram
WORK FLOW:-It is an optional object where we create different data flows, scripts.work flow is like procedure.A work flow is a reusable object. It executes only within a Job
We can use work flows to:
Call data flows
Call another work flow
Define the order of steps to be executed in your job
Pass parameters to and from data flows
Define conditions for executing sections of the project.
Specify how to handle errors that occur during execution.
Data flow:- extract, transform, and load data. Everything having to do with data, including reading sources, transforming data, and loading targets, occurs inside a data flow.This is the most important object of the hierarchy where we create our mapping. data flow is like procedureDeclarative SQL select.A data flow defines the flow of data from sources to targets.
We can use data flow to:
Identify the source data that you want to read
Define the transformations that you want to perform on the data
Identify the target table to which you want to load data
A data flow is a reusable object. It is always called from a work flow or a job.
