Custom developed code can greatly enhance the load process. Developing XML transforms, Java programs, or both allows the customer to continually deliver data in the same format regardless of the desired load file format. With the introduction of contexts, custom-built code can be used to separate data into groups of load files as is now required.

Custom code is typically used in conjunction with another tool, such as a text editor.

This approach is most likely to be used when the load file format is different from the format of the data that was provided.
