IBM Informix vs InfluxDB: What are the differences?

Introduction

IBM Informix and InfluxDB are two widely used database management systems that serve different purposes. Understanding the key differences between these two systems is important for businesses and developers to make informed decisions about which solution best fits their needs.

1. Data Model: IBM Informix is a relational database management system (RDBMS) that follows a traditional tabular data model, where data is stored in tables with rows and columns. InfluxDB, on the other hand, is a time-series database that is designed specifically for handling time-stamped or time-series data, such as sensor or IoT data. It uses a measurement/tag concept to organize data, which allows for efficient storage and retrieval of time-based data.

2. Scalability and Performance: In terms of scalability, Informix is designed to handle large amounts of data and can scale well vertically, i.e., by adding more resources to a single server. InfluxDB, however, is built for horizontal scalability, which means it can distribute data across multiple servers in a cluster, allowing for better performance and high availability. This makes InfluxDB a better choice for applications that require handling massive amounts of time-series data.

3. Query Language: Informix uses SQL (Structured Query Language), which is a standard language for relational databases, allowing users to perform various operations on structured data. InfluxDB, on the other hand, uses its own query language called InfluxQL, specifically tailored for querying time-series data. InfluxQL provides syntactic sugar and functions that make it easy to perform calculations and aggregations on time-series data.

4. Compression and Retention: InfluxDB includes built-in data compression techniques that efficiently store and retrieve time-series data. It uses a combination of compression algorithms and downsampling techniques to optimize storage and query performance. Additionally, InfluxDB provides configurable retention policies that allow users to define how long data should be retained in the database. Informix, being a traditional RDBMS, does not have these native compression and data retention capabilities.

5. Data Ingestion and Integration: InfluxDB provides various methods for data ingestion, including a native HTTP API, Telegraf (a lightweight data collector), and clients for different programming languages. It also supports integrations with popular tools and platforms in the monitoring and analytics space. Informix, being an RDBMS, supports standard methods of data ingestion such as SQL inserts, updates, and bulk loading techniques. It also provides connectors and drivers for integrating with other systems.

6. Community and Ecosystem: In terms of community support and ecosystem, InfluxDB has gained significant popularity in recent years, attracting a large and active user community. It has a rich ecosystem with numerous integrations, plugins, and extensions that extend its capabilities for different use cases. Informix, on the other hand, has a smaller user community and a more focused market share, with a specific set of enterprise customers.

In Summary, IBM Informix is a traditional RDBMS with a relational data model, while InfluxDB is a specialized time-series database with capabilities tailored for handling time-stamped data. InfluxDB is designed for horizontal scalability and optimized for time-series data storage and retrieval. It uses its own query language, provides efficient compression and retention techniques, and has a robust ecosystem of integrations and extensions.
