DB2 is a family of relational database software solutions offered by IBM. It includes standard Db2 and Db2 Warehouse editions, either deployable on-cloud, or on-premise.
Db2 provides a combination of performance and scalability. Security wise, Db2 is always a first choice, especially for the systems where security can't be compromised. For mainframe systems, there is no other DB in the market that can perform better than Db2. If an organization …
IBM Db2 in my organization has had overall a much better consistency rating and effectiveness. Turnaround times are shorter and the need for human intervention is significantly less. We find Db2 to be more reliable overall and a better experience to use. In terms on real time …
From working with other databases, I always felt that Db2 was at the top of its game in all aspects of performance, recoverability, and stability—pretty much everything you want out of an Enterprise database system.
Access controls, encryption, and auditing
capabilities are just a few of the strong security features supported by IBM Db2.I think Strong security features are offered by it, such as integration with Active Directory and LDAP enterprise security infrastructures, row and column …
Compared to similar products, Db2 shared common Relational DataBase Management System (RDBMS) features such as SQL support, data integrity, Atomicity, Consistency, Isolation and Durability (ACID) Compliance and concurrency control. However, the Db2 is designed for scalability, …
Tried tested true and dependable. Main distinguishing factor however is the ongoing time in which it has been relied on, the preference by some stakeholders for ensuring sensitive data security, and its flexibility
Db2 is one of the oldest and mature rdbms available in the market. IBM products were already been used in the organization. Cost effective in terms of licensing.
We tried MS SQL. However, MS SQL is one of the most widely used in enterprise management. However, that is mostly compatible with Microsoft services and does not provide much strength with outside applications. db2 is also open-independent and compatible with cross-platforms, …
We are working for our product , where we were using different database but that database was not fast our work So we switch to IBM Db2 for better result.
DB2 works as good as any of these databases. It is cheaper to run than any of them. It is more solid and stable that SQL server or Netezza. It is very comparable to Oracle for reliabilty.
But for administration, Netezza is a little simpler because it has no indexes. Netezza is …
DB2 was more scalable and easily configurable than other products we evaluated and short listed in terms of functionality and pricing. IBM also had a good demo on premise and provided us a sandbox experience to test out and play with the product and DB2 at that time came out …
Db2 is one of the best relational databases I’ve used. It has the ability to maintain large amount of data and execution of million transactions in fraction of a second. If you use it properly, an organization can build a database with thousands of tables, and it can provide …
It's almost not comparable because they all do the same job in varying degrees. There are some things I like about Db2 that I don't enjoy about Oracle, but it mostly comes down to how it works and where it stores everything like SYS tables in Db2. MySQL is probably the fastest …
I did not choose DB2 over any other database engine, the corporation we are currently working for uses all of them for different companies/systems/departments and we need to consolidate data from all of them into a single data warehouse. DB2 is one of the many different data …
DB2 is a similar product that is most respected. Oracle might be supported in a broader context, but DB2 is superior on every platform where the choice is there. Licensing is also a factor in which DB2 is much better, which might offset any cost differences. DB2 support is also …
I have been a SQL Server focused professional for over 20 years, so SQL Server is my first choice. I have experience and comfort, and the ability to get up to speed quickly. Oracle has been too expensive, though I think it has performed similar to SQL Server in the applications …
I've used many DBMS during my career including Oracle, DB2, SQLite and FoxPro. Since I'm more a technical guy, I personally prefer MS SQL Server more than others for its ease of use and development tools and features.
Microsoft SQL Server is a DBMS that can be used in any situation, from small projects to big ones, and the latest versions now can be used in several OS platforms. It is a great product with many features over its competitors. It's a mature and robust product. It's easy and …
Microsoft SQL Server stacks up pretty well - it is well established and has a large userbase. The main reason we selected Microsoft SQL Server over any other RDMS was because of its well established place in the market for such tools and large number of users (easy to hire …
I have primarily used it as the basis for a SIS - but I have migrated more than a few systems from there database systems to DB2 (Filemaker, MySQL, etc.). DB2 does have a better structural approach, as opposed to Filemaker, which allows for more data consistency, but this can also lead to an inflexibility that can sometimes be counterintuitive when attempting to compensate for the flexibility of the work environment as Schools tend to have an all in one approach.
Microsoft SQL is ubiquitous, while MySQL runs under the hood all over the place. Microsoft SQL is the platform taught in colleges and certification courses and is the one most likely to be used by businesses because it is backed by Microsoft. Its interface is friendly (well, as pleasant as SQL can be) and has been used by so many for so long that resources are freely available if you encounter any issues.
Microsoft SQL Server Enterprise edition has a high cost but is the only edition which supports SQL Always On Availability Groups. It would be nice to include this feature in the Standard version.
Licensing of Microsoft SQL Server is a quite complex matter, it would be good to simplify licensing in the future. For example, per core vs per user CAL licensing, as well as complex licensing scenarios in the Cloud and on Edge locations.
It would be good to include native tools for converting Oracle, DB2, Postgresql and MySQL/MariaDB databases (schema and data) for import into Microsoft SQL Server.
The DB2 database is a solid option for our school. We have been on this journey now for 3-4 years so we are still adapting to what it can do. We will renew our use of DB2 because we don’t see. Major need to change. Also, changing a main database in a school environment is a major project, so we’ll avoid that if possible.
We understand that the Microsoft SQL Server will continue to advance, offering the same robust and reliable platform while adding new features that enable us, as a software center, to create a superior product. That provides excellent performance while reducing the hardware requirements and the total cost of ownership of our solution.
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.
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.
I have never had DB2 go down unexpectedly. It just works solidly every day. When I look at the logs, sometimes DB2 has figured out there was a need to build an index. Instead of waiting for me to do it, the database automatically created the index for me. At my current company, we have had zero issues for the past 8 years. We have upgrade the server 3 times and upgraded the OS each time and the only thing we saw was that DB2 got better and faster. It is simply amazing.
The performances are exceptional if you take care to maintain the database. It is a very powerful tool and at the same time very easy to use. In our installation, we expect a DB machine on the mainframe with access to the database through ODBC connectors directly from branch servers, with fabulous end users experience.
Easily the best product support team. :) Whenever we have questions, they have answered those in a timely manner and we like how they go above and beyond to help.
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.
Other than SQL taking quite a bit of time to actually install there are no problems with installation. Even on hardware that has good performance SQL can still take close to an hour to install a typical server with management and reporting services.
DB2 was more scalable and easily configurable than other products we evaluated and short listed in terms of functionality and pricing. IBM also had a good demo on premise and provided us a sandbox experience to test out and play with the product and DB2 at that time came out better than other similar products.
[Microsoft] SQL Server has a much better community and professional support and is overall just a more reliable system with Microsoft behind it. I've used MySQL in the past and SQL Server has just become more comfortable for me and is my go to RDBMS.
By using DB2 only to support my IzPCA activities, my knowledge here is somewhat limited.
Anyway, from what I was able to understand, DB2 is extremely scallable.
Maybe the information below could serve as an example of scalability.
Customer have an huge mainframe environment, 13x z15 CECs, around 80 LPARs, and maybe more than 50 Sysplexes (I am not totally sure about this last figure...)
Today we have 7 IzPCA databases, each one in a distinct Syplex.
Plans are underway to have, at the end, an small LPAR, with only one DB2 sub-system, and with only one database, then transmit the data from a lot of other LPARs, and then process all the data in this only one database.
The IzPCA collect process (read the data received, manipulate it, and insert rows in the tables) today is a huge process, demanding many elapsed hours, and lots of CPU.
Almost 100% of the tables are PBR type, insert jobs run in parallel, but in 4 of the 7 database, it is a really a huge and long process.
Combining the INSERTs loads from the 7 databases in only one will be impossible.......,,,,
But, IzPCA recently introduced a new feature, called "Continuous Collector".
By using that feature, small amounts of data will be transmited to the central LPAR at every 5 minutes (or even less), processed immediately,in a short period of time, and withsmall use of CPU, instead of one or two transmissions by day, of very large amounts of data and the corresponding collect jobs occurring only once or twice a day, with long elapsed times, and huge comsumption of CPU
I suspect the total CPU seconds consumed will be more or less the same in both cases, but in the new method it will occur insmall bursts many times a day!!
There is great value the solution brings when it comes to building stored procedures and ongoing tasks that allows our team to streamlines processes.
The platform has allowed us to see value by providing a solution for data structuring and data hygiene which prevents deduplication of data and lowers costs
With the integration capabilities it allows our analytics team to more seamlessly create highly visible dashboards that see directly into the data and pinpoint areas that need attention.
Increased accuracy - We went from multiple users having different versions of an Excel spreadsheet to a single source of truth for our reporting.
Increased Efficiency - We can now generate reports at any time from a single source rather than multiple users spending their time collating data and generating reports.
Improved Security - Enterprise level security on a dedicated server rather than financial files on multiple laptop hard drives.
