        Data types allowed in a fixed format
        Editing a format
        After you create and save a format, you might need to add a new field, insert a new field, edit a field, or delete a field. The process for editing an existing format is essentially the same, regardless of the file type.
        Create a fixed format that uses carriage returns

Extending Informix®
Beyond standard relational database objects, HCL Informix® can be extended to handle specialized data types, access methods, routines, and other objects. Informix includes many built-in extensions that are fully integrated in the database server. Informix also provides modules, which are packages of extended database objects for a particular purpose and that are installed separately from the database server. Alternatively, you can create your own user-defined objects for Informix.
Data warehousing
In addition to designing and implementing Informix® dimensional databases, you can use tools to create data warehouse applications and optimize your data warehouse queries.
Designing databases
The first step in creating a relational database is to construct a data model, which is a precise, complete definition of the data you want to store. After you prepare your data model, you must implement it as a database and tables. To implement your data model, you first select a data type for each column and then you create a database and tables and populate the tables with data. You can also implement fragmentation strategies and control access to your data.
JSON compatibility
You can use the popular JSON-oriented query language created by MongoDB to interact with data stored in HCL Informix®.
Security
You can secure your Informix® database server and the data that is stored in your Informix databases. You can encrypt data, secure connections, control user privileges and access, and audit data security.
SQL programming
You can use the HCL Informix® implementation of the SQL language to develop applications for Informix database servers.
Troubleshooting HCL Informix®
Several troubleshooting techniques, tools, and resources are available for resolving problems that you encounter in your HCL Informix® database server environment.

Data types allowed in a fixed format

You can use the following data types when you are preparing a fixed format.


Data type	Description
Chars	ASCII format data
Short Unsigned Short Integer Unsigned Integer Long Integer Unsigned Long Float Double	The Machines description specifies the number of bytes required in fixed format for integers and floating-point values (see The Machines window.) When you select one of these data types, iploadsets the number of bytes.
Date	Date string
UNIX™ Date	A long integer interpreted as the system date from a UNIX™ system
Blob Length	The number of bytes of BYTE and TEXT (binary large object) that follow this record
Blob File	A file that contains BYTE and TEXT data
BLOB and CLOB	A file that contains smart large object (BLOB or CLOB) data
Simple LO Length	The number of bytes of simple large object data (BYTE and TEXT data) that follow this record
Simple LO File	The name of a file that contains a Simple LO data (BYTE and TEXT data)
INT8	An eight-byte integer type
SERIAL8	An eight-byte serial column
BIGINT	An ASCII character string or an eight-byte integer type
BIGSERIAL	An ASCII character string or an eight-byte integer type
Ext Type String	The ASCII representation of an extended data type (Ext Type) value
Ext Type String Length	The length of an ASCII Ext Type value. The Ext Type value follows at the end of the input/output record. Use Ext Type String Length data type if you have data that contains null UDT values.
Ext Type Binary	The binary representation of an Ext Type value
Ext Type Binary Length	The length of the binary representation of an Ext Type value. The binary value follows at the end of the input/output record. Use Ext Type Binary Length data type if you have data that contains null UDT values.

The HPL supports several data types under the Ext Type mechanism. As a result, the specific names of these data types do not appear in the data-type selection list. For the following data types, choose the appropriate Ext Type data type:

INT8
LVARCHAR
SERIAL8
BLOB
BOOLEAN
CLOB
Collection data types
Distinct data type
