SQL Server and Informix compete in the database management systems category. SQL Server has the upper hand due to its dynamic resource allocation and robust community support, while Informix excels in hybrid SQL and NoSQL capabilities, suiting IoT applications.
Features: SQL Server offers dynamic resource allocation, In-Memory OLTP, and a rich ecosystem including Management Studio. Informix supports large data sets with hybrid SQL and NoSQL capabilities and boasts an efficient replication system suited for IoT.
Room for Improvement: SQL Server's high licensing costs and resource consumption are noted concerns, alongside integration with open-source environments. Areas for Informix improvement include ease of use and greater marketing by IBM to enhance visibility and engagement.
Ease of Deployment and Customer Service: SQL Server offers diverse deployment models and extensive documentation. Despite prevalent community resources, customer support can be delayed. Informix provides similar deployment flexibility but could benefit from quicker IBM support for specific issues.
Pricing and ROI: SQL Server, while cheaper than Oracle, can be costly at an enterprise level with various licensing options, including free versions. Informix's pricing is high but offers free versions for SMBs. Both provide favorable ROI due to robust features, with perceptions of value varying by need and budget.

IBM Informix is a widely used and scalable relational database management system designed to handle large amounts of data and high transaction volumes. It is known to provide exceptional performance, thanks to its Parallel Data Query Engine (PDQ) that enables parallel processing of queries and operations, significantly reducing response times for complex queries and large data sets. Additionally, Informix supports online operations like backup, restore, index maintenance, and table reorganization, minimizing downtime and ensuring continuous availability.
Informix provides robust high availability and replication features, including shared-disk clustering, remote data replication, and high-availability data replication (HDR). These features ensure data redundancy, failover protection, and disaster recovery capabilities, making it a reliable choice for mission-critical applications. Furthermore, Informix offers specialized features for data warehousing and analytics, such as in-database analytics, data compression, and parallel load capabilities, making it suitable for business intelligence (BI) and data analysis applications.
Informix can be deployed as an embedded database, allowing it to be tightly integrated with applications and systems, reducing overhead and simplifying deployment. It includes workload management capabilities, enabling organizations to prioritize and manage different types of workloads, such as online transaction processing (OLTP) and analytical queries, ensuring efficient resource utilization and meeting service-level agreements (SLAs). Informix also provides robust security features, including role-based access control, data encryption, auditing, and compliance with industry standards like FIPS 140-2 and Common Criteria.
SQL Server is a relational database management system (RDBMS) by Microsoft. The product's main purposes are to store data and retrieve it as requested by other software applications - on the same computer or on another computer across a shared network. The solution is built on top of Structured Query Language (SQL), which is a standardized programming language used for relational database management.
The product is tied to Transact-SQL (T-SQL), which is an implementation of SQL from Microsoft that adds several proprietary programming extensions to the standard language. SQL Server is built similarly to other RDBMS products, as its structure is a row-based table that connects related data elements in different tables to one another. One of its most important components is the SQL Server Database Engine, as it controls data processing, storage, and security. Beneath the Database Engine is the SQL Server Operating System, which is used for memory and I/O management, locking data to avoid unneeded upgrades, and job scheduling.
The solution has four editions with different sets of services and tools. They include:
The first two are available for free and are typically utilized by smaller companies, as they work with fewer functions and storage. The second two editions are generally used by bigger organizations and enterprises and offer more features.
The solution has several functions through which users can facilitate different data-related processes. These include:
SQL Server Services
SQL Server has a wide range of add-on services that provide additional benefits beyond database management. These services include:
SQL Server Benefits
The solution has many benefits for users. These include the following:
Reviews from Real Users
A president at a consultancy evaluates SQL Server as a veteran solution with critical log shipping feature.
Harkamal S., a user at a manufacturing company, rates SQL Server with a high mark because it is a stable, scalable, and easy-to-deploy solution that pretty much covers everything.
