Request your data as a flat, sequential file. Analyzer works best with a flat file. In most flat files, the record length is fixed. With fixed-length files, each record has a fixed number of fields and each field is a constant length. Usually, there is only one type of record in the file.
A single record type, fixed-length file is preferable for processing; however, it is not essential. Analyzer can also process multiple-record-type files and almost any type of variable-length file.
If your data is in a relational database, you should convert it to a flat file before you download your data or copy it to tape. If you have an information systems department, ask them to assist you. You can also use ODBC to read a relational database.
Alternatively, rather than flattening the database, you might want to generate a report from the data and use Analyzer to analyze the report spool file.
