Implement data access components

Data access components represent the logic used to read, write, and map values during a data synchronization process. The data access components in this example represent the ability to read values at specific positions from a line in a text file.

For example, consider a file that contains comma-separated values (CSV) that provide details about new customers. The file looks like the following:

first,last,company
Aaron,Adkins,Ace Corp
Brad,Bedford,Burnside Bread
Charlotte,Colson,Carefree Farms

The pipeline step processor ReadTextFileStepProcessor reads each row from a file and creates an array of values using the specified delimiter. In this example, the delimiter is a comma.

You use data access components to control how the values in that array are accessed. In this example, you use the data access components to identify the following:

This section shows you how to implement the required data access components.
