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 DataBlade® 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.
You can create user-defined data types, routines, access methods, and other database objects to suit your needs. You can use application programming interfaces to write user-defined routines and applications that access data in Informix® databases.
The DataBlade® Developers Kit (DBDK) guides contain information about the tools you can use to develop and package DataBlade modules, which extend the functionality of HCL Informix® databases.
These topics describe how to use Informix® DataBlade® Developers Kit (DBDK) tools to develop and package DataBlade modules.
This section describes the DataBlade® module SQL design issues.
Welcome to the documentation for HCL Informix® 15.0 and related client tools and products.
HCL Informix® is a fast and scalable database server that manages traditional relational, object-relational, and dimensional databases. Its small footprint and self-managing capabilities are suited to embedded data-management solutions.
These topics describe how to install HCL Informix® database servers, client products, and DataBlade® modules.
In addition to administering the database server, you can tune performance, replicate data, and archive data.
You can upgrade to the 15.0 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.
You can use the HCL Informix® implementation of client APIs to develop applications for Informix database servers.
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.
These topics describe how to use built-in database extensions and separately installed DataBlade® modules.
These topics describe information about the DataBlade® API, the C-language application programming interface (API) provided with HCL Informix®.
These topics describe the DataBlade® API functions and the subset of IBM® Informix® ESQL/C functions that the DataBlade API supports.
These topics serve as an overview of the HCL Informix® DataBlade® module development process.The HCL Informix DataBlade module overview serves as an overview of the HCL Informix DataBlade module development process.
This section provides an overview of DataBlade® module development and describes the resources and tools the HCL Informix® database server provides to facilitate development.
A data model is a high-level definition of a DataBlade® module: what objects it represents and what operations on those objects it provides.
After you have designed a data model for your DataBlade® module, you can design its specifics, such as data types to best represent your DataBlade module objects.
The next component in DataBlade® module design is the query language interface.
To develop a DataBlade® module, you need a general understanding of query processing and HCL Informix® SQL. You must also understand the execution environment inside your Informix database server ̵ the multithreading model, the collection of processes in which DataBlade module routines can execute, and concurrent access to database objects, transactions, and so on.
The interoperability of a DataBlade® module refers to how well that module works with your HCL Informix® database server and with other DataBlade modules.
Use this section to help you when you write the design specification for your DataBlade® module.
Use BladeSmith to create DataBlade® modules.
This section contains information to help you edit and compile C language source code generated by DataBlade®.
This section describes how to use the Informix® DataBlade® Developers Kit (DBDK) to create ActiveX value objects. This section describes the use of C++ to implement opaque type support routines.
This section provides information for client application developers who are using ActiveX value objects.

These topics describe how to write user-defined routines (UDRs) in the Java™ programming language for Informix®.
These topics describe the HCL Informix® R-tree secondary access method and how to access and use its components.
These topics describe how to define new data types and enable user-defined routines (UDRs) to extend HCL Informix®.
These topics explain how to create a primary access method with the Virtual-Table Interface (VTI) so that users have a single SQL interface to HCL Informix® tables and to data that does not conform to the storage scheme of HCL Informix.
These topics explain how to create a secondary access method with the Virtual-Index Interface (VII) to extend the built-in indexing schemes of HCL Informix® typically with a DataBlade® module.
In addition to designing and implementing Informix® dimensional databases, you can use tools to create data warehouse applications and optimize your data warehouse queries.
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.
You can use the popular JSON-oriented query language created by MongoDB to interact with data stored in HCL Informix®.
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.
You can use the HCL Informix® implementation of the SQL language to develop applications for Informix database servers.
Several troubleshooting techniques, tools, and resources are available for resolving problems that you encounter in your HCL Informix® database server environment.
