IBM

Excellent product, very manageable across multiple platforms, paramount in recovery and backups. It has an automated system with great features that allow data to be stored easily. We have this software that is the best base for the data for a load of a quantity of data. With this relational database tool, we obtain excellent service in the company with excellent achievements. It has a quality technical service that makes what seems complicated easy.

Oracle

Including other products, Oracle is very specialized in business support. Choosing Oracle Data Warehouse would be a safe choice for an enterprise-level company (more than a thousand employees). Healthcare organizations may want to consider Oracle, as they are typically conservative with privacy and security issues with patient data. Although cloud-based systems are widely being adopted in the healthcare industry (such as population research or genomics), core data sets (such as patients' sensitive medical records) may be better stored with a home-grown data center and warehouse solution.

Pros

IBM

  • DB2 maintains itself very well. The Task Scheduler component of DB2 allows for statistics gathering and reorganization of indexes and tables without user interaction or without specific knowledge of cron or Windows Task Scheduler / Scheduled jobs.
  • Its use of ASYNC, NEARSYNC, and SYNC HADR (High Availability Disaster Recovery ) models gives you a range of options for maintaining a very high uptime ratio. Failover from PRIMARY to SECONDARY becomes very easy with just a single command or windowed mouse click.
  • Task Scheduler ( DB2 9.7 and earlier ) allows for jobs to be run within other jobs, and exit and error codes can define what other jobs are run. This allows for ease of maintenance without third party softwares.
  • Tablespace usage and automatic storage help keep your data segmented while at rest, making partitioning easier.
  • Ability to run commands via CLI (Command Line Interface) or via Control Center / Data Studio ( DB2 10.x+) makes administration a breeze.

Oracle

  • Able to handle very large data sizes efficiently from a performance, high availability and manageability perspective. This is accomplished through the Oracle Partitioning functionality. Partitioning allows large segments (tables, IOT index-organized tables, indexes) to be broken into smaller segments at the physical layer but treated as a whole at the logical layer.
  • Provides support for dual-format architecture through Oracle In-Memory functionality. Without any change to application code one can obtain in-memory performance. This functionality enables us to have the tables represented in both the row format and the column format using in-memory format. This is a huge boost for BI/analytic queries since the Oracle optimizer is able to intelligently choose the appropriate format.
  • Provision to materialize a subset of table data or table joins. This is through materialized views and the optimizer will rewrite the query against the base tables to make use of this materialized view. This provides a huge performance boost and is critical in VLDBs as in a data warehouse. The query rewrite is fully transparent to users.
  • Provides multiple compression capabilities. This is very useful not only for deducing the storage foot print but as well as increase performance at different layers of the infrastructure including query performance. The compression functionality can be applied against both structured and unstructured data.
  • With the advent of Engineered Systems (Exadata, Database Machine, SuperCluster) there are specific features and functionalities that can further boost the Oracle data warehouse. These are related to consolidation, Smart Scan, Storage Indexes, EHCC (Exadata hybrid columnar compression) and much more.
  • RAC - Real Application Clusters (with 2 or more nodes) provides functionality for high availability, performance and scaling as the work load increases. The parallelism is provided both within a node and as well as across nodes. If for any reason a node goes down the data warehouse is still available through other nodes and the running queries are transparently failed over to the surviving nodes.

Cons

IBM

  • everything about Db2 is 'heavy', even the Community edition and some of the clients
  • difficult to configure for beginners /option overload
  • LUW and z platforms have minor inconsistencies that really should be a non-issue
  • support seems to be declining in terms of quality/quickness of responses

Oracle

  • Customer support isn't the best out there. We usually have to wait about an hour to get some form of assistance.
  • Pricing is a bit higher than many of its competitors such as AWS Redshift.
  • Tweaking features requires dedicated staff. Software is fairly advanced. Would be difficult to use for newcomers.

    Since our services are running in IBM Kubernetes, using IBM Cloud Databases seem to be the best option. It may provide better performance than other vendors as everything is running in the same cloud. The overall experience so far is good as well.

    You have to be well versed in using the technology, not only from a GUI interface but from a command line interface to successfully use this software to its fullest.

    Reliability and Availability

    IBM

    To maximize availability, just provide backup data sharing files with each other. The DB2 self-protects itself from interruptions and there are many error messages to intercept to avoid the crash. OOTB, the guarantee of reliability is very high. Undoubtedly, the true enterprise solution that guarantees the business. No doubt at all.

    Performance

    IBM

    DB2 for i has very good performance and great tools to monitor and tune that performance as well. IBM Navigator for i, an integrated management interface, allows for real-time monitoring of user-defined parameters. Index Advisor, SQL Plan Cache and other ACS tools allow the DBE to further tune the performance and even change those settings depending on the time of day or workload running.

    Microsoft SQL Server and IBM Db2 both [have] their own advantages and performance optimization mechanism, but IDM Db2 is ahead on the race when we want better security and [easy] database management on the cloud. We [do not need to install Microsoft SQL Server in our remote server, we can directly use DB2 on Cloud and connect within [a] few minutes. It provides Auto-scaling without [downtime], [in] which users don't get any glitches or errors.

    Oracle is, in my opinion, the top dog in this space. I feel like the other vendors are playing catch-up to where Oracle is right now. It is also likely the most expensive option out there.

    Scalability

    IBM

    This IBM service is perfect for companies that have other services that can be integrated as in other IBM software; in relation to its scalability, I cannot give a precise opinion; based on the fact that it is an IBM database service, I consider that its The level of scalability is acceptable, but I don't think it will have an amazing level of enhanced growth, the company took advantage of this service to store important data, and it is used as an integrated module of another IBM product.

    Return on Investment

    IBM

    • We have dealt with technical support on several occasions. Whenever we run into issues, the specialist team is involved and the resolution cycle is stretched. We have to rely on makeshift solutions and the issues keep recurring. Ultimately, the product itself has challenges and we are not currently satisfied with the support, either.
    • Scalability has been a problem area. We have traffic on the order of gigabytes and it impacts our queries and responses a lot. Considering the volume that we have, it manifests itself into a multitude of issues.

    • Very cost effective for large databases.
    • Very fast results on simple queries.
    • Analytical functionalities are of wide range, which makes it very cost effective.
    • For smaller businesses, it might be a great asset.
    • Some features are supposed to be bought separately, so one needs to consider this before licensing with Oracle DW.
