IBM Informix

  • Like most RDBMS servers, Informix is strong in OLTP so it is a good choice for any high volume transaction systems including retail, banking, online gambling, etc.
  • Because its memory and storage footprints are relatively small and its installation footprint can be adjusted by deselecting unneeded features during installation, and also in large part to the autonomic tuning features of Informix, it is ideal for embedded systems and is used as the embedded database engine for several mainstream products in telecommunications, environmental management, and similar systems.
  • Its ability to integrate timeseries data with relational data make it ideal for monitoring and for the analytical processing of time oriented data such as utility supply, weather tracking, logistics and warehouse management, etc.
  • Informix's support for JSON/BSON data types and for the MongoDB API and wire listener protocol, in addition to the extensions Informix adds to the MongoDB API to support relational data, generic SQL statements, and multi-step transactions make it an ideal drop in replacement for MongoDB and other document oriented databases when application requirements exceed the capabilities and performance characteristics of these NoSQL database systems.
  • The Informix Warehouse Accelerator (IWA) feature of the Informix Advanced Enterprise Edition can accelerate data warehouse queries several hundred times over the speed of the base Informix and other RDBMS servers. In addition, IWA provides this acceleration with no modifications to applications and analytical tools and without the need to create additional indexes, cubes, or pre-calculated summary tables. Further, queries accelerated with IWA do not affect the performance of simpler queries running in the base Informix engine allowing IWA to provide an analytical query engine on top of a operational data store without complex ETL/ELT data migrations/conversions.

Microsoft SQL Server

I've found Microsoft SQL Server a robust and affordable solution for most OLTP scenarios, starting with department solutions up to enterprise-level systems. There are many advanced features (like compression and partitioning) that correctly implemented provide huge benefits on performance, reducing hardware requirements and costs. The default locking mechanism can be a problem for systems with high concurrency if the READ_COMMITTED_SNAPSHOT option is not selected.

Pros

IBM Informix

  • Informix since its conception has a distinct multi-threading architecture no other engine has, it is unique of its kind. This is precisely how the engine is able to scale up like no other, with the lowest footprint, without killing the host and profiting each bit of the hardware. The threads are sub-proceses like any other one, but the difference is that they are are not controlled by the OS process dispatcher. This is why you will never be able to see these threads running at OS level. Informix is an OS itself, on top of the OS.
  • Informix has the best replication techniques. Not many ppl know that MongoDB (the NoSQL engine) scales out because of its data sharding replication technology, and Informix is able to store Mongo BSON documents using the same data partitioning as MongoDB does. This way Informix extends the SQL or structured data with the unstructured data natively, together within the same data repository. This means that it is not only able to store JSON/BSON documents, but the engine is able to behave as it would be the MongoDB engine itself. Any application using MongoDB can be redirected to the Informix Mongo wire listener transparently. What´s more, it also improves the NoSQL (BASE) characteristic, making it ACID by allowing transactions to the CRUD operations. This last is something MongoDB is working on, promised to be delivered next year.
  • As described previously, MongoDB's sharding concept relies on data partitioning, this is how it scales out, and as I also described previously Informix scales up given the described multithreading unique architecture! It implements the data sharding with one of its best replication technologies called Enterprise Replication. This is an Active-Active replication technology that allows replicating even between different platforms. This is actually how I managed to migrate the whole Informix platform from Solaris to Linux, with just a DNS change. There was almost ZERO downtime nor application change - this was really amazing!.

Microsoft SQL Server

  • Easy to setup with the included Wizard that helps to get you up and running with the essential components covered. You won't waste a lot of time reading through documentation to just get started.
  • There is a large community of support for Microsoft SQL Server that can help to troubleshoot issues and explain how to tackle a problem.
  • The other components and modules to the system make is easy to setup backups and connections to other services.

Cons

IBM Informix

  • The name of Informix is almost invisible on the market, which is very frustrating. This give the feeling that IBM is not interested in Informix without providing any reasons for why IBM makes no effort to sell Informix.
  • The pricing policy is very complex
Eric Vercelletto | TrustRadius Reviewer

Microsoft SQL Server

  • There isn't as much that I dislike with SQL Server. It will be good to have features where we have fine grain control over internal things. For example, it would have been a good feature to have historical tracking of the metrics as opposed to setting up custom metrics. Overall SQL Server made my life easy to manage a lot of databases and ease of use while migration projects.
  • The database is the target of many attacks from it's SA account, this must come disabled by default and just after the instalation, some of 30 seconds, the attacks start, with many requests per second, it needs to improve the firewall to prevent these attacks, or put the SQL Server inside of a VPN and local network to avoid these attacks.
  • It requires knowledge and in-depth technical skills to make complex processes truly performing, especially if we are in very complex infrastructures

We are a Microsoft Gold partner and are very in depth with our SQL server development with out software and it would take too many resources to try and switch to another database product, not to mention all of our clients run SQL Server so we would then have to support SQL and another product which is fiscally irresponsible.

SQL Server mostly 'just works' or generates error messages to help you sort out the trouble. You can usually count on the product to get the job done and keep an eye on your potential mistakes. Interaction with other Microsoft products makes operating as a Windows user pretty straight forward. Digging through the multitude of dialogs and wizards can be a pain, but the answer is usually there somewhere.

We managed to handle most of our problems by looking into Microsoft's official documentation that has everything explained and almost every function has an example that illustrates in detail how a particular functionality works. Just like PowerShell has the ability to show you an example of how some cmdlet works, that is the case also here, and in my opinion, it is a very good practice and I like it.

As mentioned before, the implementation of SQL Server in a company that is beginning to use a new structure, which does not require any type of data migration, do not requires particular comment to make.
If you must to do a porting of databases from a different platform, definitely you need to consider the situation in detail depending on your needs.

Alternatives Considered

IBM Informix

You could use any other relational database, but they will be either expensive to maintain or won't scale as much.
Jean Georges Perrin | TrustRadius Reviewer

Microsoft SQL Server

The reason we've decided to go with Microsoft over Oracle or MySQL is because our company lives in the Microsoft ecosystem. It works well with other Microsoft products (Exchange, Office, etc.). It allows for easier integration. Also, the support from Microsoft is crucial, in case we run across complicated issues. They've helped as a lot. Our company actually maintained the largest Microsoft Dynamics database at one time, and there were several times we've had to reach out to Microsoft to fix unique errors and issues we had.

Return on Investment

IBM Informix

  • As I have explained earlier, Informix has had along the past 15 years, the lowest number of vulnerability defects reported in NVD. Informix allows you to disregard the vulnerability defects, and spend your time building and growing your business instead of wasting it in patching and fixing every quarter! This to me is the best example I can empirically prove that Informix is definitely one of the best return of investment and so that any CDO or CIO should pay attention at the time to consider what platform to chose, to build on top!
  • The other return of investment any CDO or CIO should pay attention to, is the number of DBAs a DB platform should be required to support it! Informix with the SELF-everything, is getting chosen by companies as the best suited engine given its low footprint and little maintenance to get it embedded in their hardware.
  • Given its uptime and minimum planned outages Informix allows you to have, it is yet another reason Informix is not means an investment and not a money waste!

  • We can very quickly and easily start up a new database.
  • Active Directory integration has been a huge time saver for us.
  • It changed the way we did our data backup strategy by giving us a backup 4-5 times a day instead of once at night.
