In the Flat file database, each line of the plain text file holds only one record. Flat file databases were developed by IBM in the early 1970s. It is the most important type of database used to store data in a plain text file (MS Excel). In that case, this attribute is required.A Flat file database is also known as the text database. scale: Only used if the field type is FixedDecimal.See Data Types for descriptions and examples of these types. Byte is an unsigned number between 0 and 255, so the size of the byte is 3 characters.Valid types for flat files are Bool, Byte, Int16, Int32, Int64, FixedDecimal, Float, String, and V_String. fields: Contains one or many field elements.trimWhiteSpace: When this is true, blank characters are trimmed from field data.Valid options are true (t) or false (f)(default). allowLongLines: Indicates if there can be extra characters after the last field for the current record.Valid options are true (t) or false (f) (default). This is valid only for data with line ends. allowShortLines: Indicates if a record can end before all fields are read.Valid options are none, crlf(default is Windows), lf(Unix), and cr(Mac). eoltype: The kind of line ends that you want to use.It can be absolute or relative to the description file. file: Declares where the actual flat-ASCII data is located and what kind of properties it has.The flatfile element contains these child elements: The root element is flatfile with a version attribute, which must be set to 1. flat file is written in XML and can be modified to describe information about the structure and data types of fields. If you are reading an unknown file type into Designer and have selected the Read it as a fixed width text file option, see Flat File Layout. Use an Input Data tool and Output Data tool to read and write. For information on data types, go to Data Types. The actual ASCII data does not contain any information about the structure of fields nor the data types of those fields. The flat file type (.flat) is used with ASCII files (.asc) which contain fixed-length fields and optional line ends to mark the end of records.
