Db2 vs. LibreOffice

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.

If you're working with numbers, LibreOffice doesn't get in your way and try to make changes as it sees fit, forcing you to repeatedly go back and undo processes you didn't want, didn't ask for, and that have no place in the document you are trying to produce. All I want to do is assemble the data, process it for the task at hand, and then print it for distribution. LibreOffice allows me to do that.

• While we query a large set of data, the results are generally available within a minute or so.
• Always reliable - I have never experienced an application going down.
• It is easy to write queries and find tables and columns.
• We can log in smoothly without any headaches.

• Tools like speeling, grammar, and thesaurus are super fast and intuitive
• Read-only content can be created by adding a section and password
• The right-click menus are very intuitive and change on the fly with what is needed depending on the content and situation
• Documents can be saved natively as *.docx or *.xlsx

• Learning curve for DB resources - Improvements to UI or native command line built-ins can help with increasing efficiencies for DB resources
• Better resource utilization monitoring and recommendations
• Continue to adopt support for modern frameworks and languages making it easier for organizations to see making Db2 the easy first choice

• It doesn't provide all the functions it should with a paid subscription.
• There are features that are only available with Premium and I have premium and they are still not available.
• Paying for the premium version doesn't provide additional services than free version
• Customer service is nonresponsive and has been nonresponsive for years even prior to COVID.

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 use it consistently and have a lot of documents in the OpenDocument format so it will be necessary to use LibreOffice or a compatible product such as Openoffice in the future to be able to open these files. Because the license fee for Libreoffice is zero it is not very costly to keep using it - the costs are mostly for keeping it installed on the office PCs and regularly updated, and solving employee issues with the user support.

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.

For all of the reasons in the foregoing evaluation. Its menus are clean, intuitive and straightforward. Any function I need to use can be accessed via keystrokes, without having to stop, move my hand to the mouse, deal with it, and then get back to the keyboard to proceed. It helps me keep my mind on my work and not worry about dealing with the mouse all the time.

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.

Libreoffice is a desktop app not requiring any server part so it is always available when the PC is working normally. Installing it on another machine if one PC fails is very quick and easy. This is a non-issue.

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.

For big/imported tables or text documents with images loaded from the internet it is sometimes getting very slow, RAM and CPU intensive, and sometimes even hangs due to some memory leaks or other bugs. This is a long-term problem and is still not resolved perfectly.

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.

Support is not officially offered. However, you can find answers to any usage questions or trouble-shooting online easily, typically starting with a Google search. (I believe that all forums / tips for OpenOffice apply equally to LibreOffice, and vice versa.) While Microsoft Office, for example, officially includes support, I find that typically you end up going to a Google search in any case. So, this is not really a downside. However, in all these cases, you end up doing a lot of figuring things out for yourself.

db2 work well with the application, also the replication tool can keep it up

Generally easy to perform, issues are how to ensure regular automatic updates on Mac OS X. Fortunatly we have only a few machines with OS X run by management and we can do these updates manually occasionally. Windows updates are quite easy with the support of third party software such as Ninite or Chocolatey, and Linux updates are super-easy thanks to the package manager (apt-get).

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.

I think it is fair to say this:

• If you are looking for a well-rounded, GNU-licensed product that will encompass word processing, spreadsheets, presentations, and database then LibreOffice is probably all you need.
• For online collaboration, links with cloud storage, and more robust support, Microsoft Office 365 and Google Docs are probably what you or your organization needs.
• LibreOffice is at its best for regular document creation and spreadsheet management. It is more cumbersome when it comes to fonts but also when it comes to linkages with cloud-based services. It is there, but you need some more computer knowledge to make it work.
• There are other free alternatives, most notably Apache Open Office, which is also a very good alternative if you do not like LibreOffice.

Having said that, I honestly think off-line computers or laptops used off-site can certainly benefit from having LibreOffice installed.

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 with small 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 in small bursts
many times a day!!

With more users using it in the company there are more cases when a simultaneous editing of the same document is needed and this feature is lacking in Libreoffice even though the files concerned are shared and synced by some solution (we use ownCloud). Google Docs or MS Office365 via Sharepoint/Onedrive offer a better function for this.

• I am able to quickly create and edit word processing documents and spreadsheets which are for all intents and purposes equivalent to documents I could create and edit in other tools such as Microsoft Office and Google Docs/Sheets.
• Lack of an online portal for sharing documents necessitates the use of Google Sheets for automation/integration. Ideal would be an all-in-one solution.
• Having open-source software that provides common functionality eliminates the need for expensive licenses.
• Lack of dedicated support is negligible. Most issues can be resolved using online search.
