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.
Informix® extensions and modules
These topics describe how to use built-in database extensions and separately installed modules.
TimeSeries Data User's Guide
The IBM® Informix® TimeSeries Data User's Guide contains information to assist you in using the TimeSeries extension with HCL Informix.
Pattern matching searches
You can search time series data for matches to a particular pattern of values. For example, after you identify a pattern of abnormal electricity usage that indicates an outage, you can search for matches to that pattern to find other outages. Pattern matching searches find matches to a pattern that you supply. Pattern matching searches do not discover patterns in time series data.
Pattern matching routines
Use pattern matching routines to run pattern matching searches, to index data for pattern matching searches, and to perform maintenance tasks.

- Informix® extensions and modules
  These topics describe how to use built-in database extensions and separately installed modules.
  - Database Extensions User's Guide
    The IBM® Informix® Database Extensions User's Guide explains how to use the database extensions that come with HCL Informix: Large Object Locator, MQ messaging, binary data types, basic text search, node data type, and SQL packages.
  - Performing XML Publishing
    The IBM® Informix® XML User's Guide includes information about using built-in functions for XML publishing with HCL Informix.
  - Spatial Data User's Guide
    The contains information to assist you in using the HCL® Informix® spatial extension. The HCL Informix spatial extension adds custom data types and supporting routines to the server.
  - TimeSeries Data User's Guide
    The IBM® Informix® TimeSeries Data User's Guide contains information to assist you in using the TimeSeries extension with HCL Informix.
    - Informix® TimeSeries solution
      Database administrators and applications developers use the Informix® TimeSeries solution to store and analyze time series data.
    - Data types and system tables
      Specialized data types and system tables handle time series data.
    - Create and manage a time series through SQL
      Before you can load time series data into the database, you must configure database objects specific to your time series. You can manage data storage and remove data as necessary. You can run SQL statements to create and manage time series.
    - Virtual tables for time series data
      A virtual table provides a relational view of your time series data.
    - Pattern matching searches
      You can search time series data for matches to a particular pattern of values. For example, after you identify a pattern of abnormal electricity usage that indicates an outage, you can search for matches to that pattern to find other outages. Pattern matching searches find matches to a pattern that you supply. Pattern matching searches do not discover patterns in time series data.
      - Requirements for pattern matching searches
        The table and time series definition must meet the requirements for pattern matching queries and the appropriate extensions must be registered.
      - Pattern matching criteria
      - Indexes on patterns
        You can create a pattern matching index on a time series to speed pattern matching queries.
      - Pattern matching routines
        Use pattern matching routines to run pattern matching searches, to index data for pattern matching searches, and to perform maintenance tasks.
        getPatternFromTS function
        The getPatternFromTS function returns a list of values that you can use as a search pattern.
        TSCreatePatternIndex function
        The TSCreatePatternIndex function indexes time series data for pattern matching searches.
        TSPatternMatch function
        The TSPatternMatch function returns matches to a specified pattern of values.
        TSDropPatternIndex function
        The TSDropPatternIndex function drops the specified pattern matching index.
        TSPIndexCleanup procedure

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.
