        The tables in the onpload database hold information that the onpload utility uses. This section describes the tables in the onpload database that you create or modify with ipload.
        The defaults table in the onpload database
        The defaults table contains default values that the uses. When ipload creates the onpload database, it inserts a single row into this table. This row specifies the default configuration assumptions for the database server, the type of computer, and the data code set.
        The delimiters table in the onpload database
        The ipload utility uses the values in the delimiters table to display the field-delimiter values that the Delimiter Options window shows. When ipload creates the onpload database, it inserts values into this table. The values in the delimiters table are for reference and do not change.

        The mapitem table in the onpload database
        The mapitem table defines the relationship between the columns of a database table and the record fields of a data file. The table stores pairs of column/record entries. The map options modify this table.
        The mapoption table in the onpload database
        The mapoption table defines conversion options for the mapping pairs that are defined in mapitem table. Use the Mapping Options window to modify this table.
        The maps table in the onpload database
        The maps table defines record-to-table mappings (for loads) and query-to-record mappings (for unloads). Use the map options to modify this table.
        The note table in the onpload database
        The note table holds comments that you can store about the components that are used for loads and unloads. You can store notes about all of the onpload components: projects, devices, formats, maps, queries, filters, and load and unload jobs.
        The project table in the onpload database
        The project table lists the projects in this onpload database. Use the Project window to modify this table.
        The query table in the onpload database
        The query table stores the queries that are used for unloading data from an HCL Informix® database. Use the Query-Definition window to modify this table.
        The session table in the onpload database
        The session table controls the parameters that onpload uses to start a load or unload job.
      - High-Performance Loader configuration file
        The default $INFORMIXDIR/etc/plconfig.std file on UNIX™ or %\INFORMIXDIR%\etc\plconfig.std on Windows™ is the high-performance loader configuration file.
      - Picture strings
        The HPL uses two types of picture strings: COBOL picture strings and other picture strings.
      - Match condition operators and characters
        This section describes the operators that are available when you match text and it provides an example of each operator.
      - Custom-conversion functions
        Custom-conversion functions allow you to add additional data conversion capability to the . This feature lets onpload call a custom-conversion function during the data-conversion process.
      - The onstat -j option
        The -j option of the onstat utility provides special information about the status of an onpload job. The -j option provides an interactive mode that is analogous to onstat -i.
      - The HPL log-file and pop-up messages
        This section provides explanatory notes and corrective actions for unnumbered messages that print in the log file. The section also includes information specific to messages that are returned to standard output or appear in a pop-up dialog box (depending on the way you started onpload).
      - Custom drivers

      - Run load and unload jobs on a Windows™ computer
      - Conversion and reversion scripts for HPL database migration
        When you convert or revert to different versions of the database server, you can use conversion and reversion scripts to manually upgrade or revert your onpload database. You must use these scripts if you are required to upgrade between the same server versions.

Migrating and upgrading
You can upgrade to the 15.0.0 release of HCL Informix® or migrate from other database servers to Informix. Upgrading is an in-place migration method that uses your existing hardware and operating system software. Some changes to the Informix database server can affect upgrading from a previous release.
Client APIs and tools
You can use the HCL Informix® implementation of client APIs to develop applications for Informix database servers.
Embedding Informix®
When you embed HCL Informix®, you can use enterprise-class high-availability and high performance with embeddability features such as easy programmability, a small disk and memory footprint, and silent deployment.
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.
