In this case, describes fixed-length text file in the format handed by DataSpider Servista (hereinafter referred to as fixed-length file).
The most basic structure of a fixed-length record file is record.Record represents one line of text file, from the beginning to end of line (newline) is called 1 record.Each record is made with multiple fields, the fields are separated to fixed-length respectively.(Figure 1)
Type in each field (numeric date string tag) can be specified.String, Number, Date are used to check the integrity of the fields.
Tag is used as record identifier.Tag is a string value.Tags become helpful in a transaction, which is roughly an iteration through the rows until the string value specified appears in a certain position.
The number of the fields and their data types for the each record found in the file do not have to be all the same.
The occurrences of a specific record can be specified, which becomes useful when you need to assure that there are 3 rows of the specified record exist. 0 - unlimited can be specified.
Multiple records treated as one unit is called group(group)(Figure 3) Each record included in a group are arranged in the order they appear in the fixed-length file. The number of the fields and their data types need to match the entries in the fixed length file.
The order and the number of records in a group do not have to be the same as the entries of the fixed length file.
The occurrences of groups can be specified 0 - unlimited can be specified.
