In order to use the import processes for more than a simple "one file" family import, you must have some understanding of relational database concepts. The import processes are intended for those who can comfortably manipulate data in Excel or work with tables in Access.

To import a single file with clean, well-formatted family information, the key fields discussed in this section are not required. Key fields are typically needed when you process multiple files or when you process a single file multiple times. This way, the program can understand the relationship between the files.
