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.
These topics describe the Global Language Support (GLS) feature available in HCL® Informix® products.
The HCL Informix® Object Interface for C++ encapsulates HCL Informix database server features into a class hierarchy.
To interact with a database, your C++ client application uses the operation classes of the HCL Informix® Object Interface for C++. These classes have methods for opening database connections, submitting queries, and manipulating database cursors. This section describes how to use these methods.
This section describes the specific value interfaces in detail, and shows how to modify value objects and extract information through the value interfaces into host variables in your application.
When you retrieve values from the HCL Informix® database by using the HCL Informix Object Interface for C++, the values are returned as value objects. Value objects are created by the Object Interface for C++ by using an extensible class factory that maps Informix data types to C++ objects.
This section is an alphabetized reference that lists and describes the HCL Informix® Object Interface for C++ operation classes. Each class has an assignment operator and a copy constructor, which are not listed in the tables of methods.
This section lists and describes the HCL Informix® Object Interface for C++ value interfaces. The ITFactoryList and ITPreserveData classes provide support for value interfaces.
This section lists the server data types and the interfaces supported for them.
This method returns a GLS error number.
This section describes the ITLocale methods for comparing strings.
This section describes the ITLocale methods for processing strings.
This topic describes the ITLocale method for determining the client locale.
This method converts the string of multibyte characters in from to another code set and copies the result to the location pointed to by to.
This method determines if conversion is necessary from the code set associated with the fromLocaleName locale to the code set associated with the toLocalename locale.
This method calculates the number of bytes needed to convert the multibyte characters in nfrombytes from the code set associated with the fromLocaleName locale to the code set associated with the toLocaleName locale.
This section describes the ITLocale methods for classifying characters.
This section describes the ITLocale methods for converting the case of characters.
This section describes the ITLocale methods for converting built-in data types to an internal representation.
This section describes the ITLocale methods for converting characters and character strings between their multibyte and wide character representations.
This section describes the following ITLocale methods for converting built-in data types to an internal representation.
Starting with CSDK 4.50.xC4, Informix .NET Core Provider built with .NET Core SDK/Runtime v3.1 is shipped for Windows x64 and Linux x86_64 platforms.
These topics include information about HCL Informix®4GL and SQL.
These topics include information about the translated user interface files for Informix® UNIX™ products, locales, and code set conversion tables
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.
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.
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.
