Creating data dictionaries
You can create a new data dictionary manually. It may be easier to start with an existing data dictionary that was created by Unica Campaign.
About this task
Procedure
- Create an empty .dat file (length = 0) and a corresponding .dct file.
- In the .dct file, define fields in the format:
<Variable_name>, <"ASCII string" or "ASCII Numeric">, <Length_in_bytes>, <Decimal_point >, <Format>, <Comment>
Use Unknown for the format and leave the comment field blank, as shown in the following example:
acct_id, ASCII string, 15, 0, Unknown, hsehld_id, ASCII Numeric, 16, 0, Unknown, occptn_cd, ASCII string, 2, 0, Unknown, dob, ASCII string, 10, 0, Unknown, natural_lang, ASCII string, 2, 0, Unknown, commun_lang, ASCII string, 2, 0, Unknown,
- You can now map a new table to a file using this data dictionary.
