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.

Installing
These topics describe how to install HCL Informix® database servers, client products, and modules.
Administering
In addition to administering the database server, you can tune performance, replicate data, and archive data.
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.

    - Informix® TimeSeries solution
      Database administrators and applications developers use the Informix® TimeSeries solution to store and analyze time series data.
      - Informix® TimeSeries solution architecture
        The Informix® TimeSeries solution consists of built-in data types and routines. You can use other Informix tools to administer and load time series data.
      - Time series concepts
        A time series as implemented by the Informix® TimeSeries solution contains information about how the data is stored in the table column and information about valid data intervals and where the data is stored on disk.
      - Getting started with the Informix® TimeSeries solution
        Before you can create a time series, decide on the properties of the time series and where to store the time series data. After you create a time series, you load the data and query the data.
      - Hardware and software requirements for the TimeSeries solution
        Before you create a time series, ensure that you have the required hardware and software, a supported operating system, and that you understand the restrictions for SQL statements and data replication.
      - Sample smart meter data
        If you want to practice querying time series data before you define and load your time series, you can use the sample data in the stores_demo database.
      - Setting up stock data examples
        Set up the stock data examples. Use the sample queries and sample programs to practice handling 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.
    - Advanced analytics
      Advanced analytics functions provide specialized methods of analyzing time series data for patterns or abnormalities.
    - Calendar pattern routines
      You can use calendar pattern routines to manipulate calendar patterns.
    - Calendar routines
      You can use calendar routines to manipulate calendars.
    - Time series SQL routines
    - Time series Java™ class library
      You can use the time series Java™ class library to create and manage a time series from within Java applications or applets.
    - Time series API routines
      The time series application programming interface routines allow application programmers to directly access a time series datum.
    - Appendixes
  - Spatiotemporal Search for Moving Objects User's Guide
    The describes how to program applications to search data from moving objects in HCL Informix® databases using the spatiotemporal search extension.
- Creating extensions
  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.
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.

Informix® TimeSeries solution architecture

The Informix® TimeSeries solution consists of built-in data types and routines. You can use other Informix® tools to administer and load time series data.

The Informix® database server includes the following functionality for managing time series data:

The TimeSeries data type and other related data types to configure the data.
