Oracle APEX
Score 7.8 out of 10

Oracle APEX (or Oracle Application Express) is an online low-code application builder that allows users to develop a database-drive application, customize the application's UI, and then give their users access to the application via URL. Oracle APEX includes a suite of pre-built productivity applications and examples, such as a Survey Builder, Bug Tracking, P-Track project management, etc
unlike other database Db2 work in diffent concept.most of the org use db to manage huge chuck of data and process faster with less time.other database will be failed to do such task or success rate will be less
I could think of a couple but the obvious is in Fintech and Retail, because of the amount of transactional and event level data for global operations. It is imperative to have a solution that can handle such large scale date, in real-time and batch delivery for inbound and outbound delivery, and ultimately ensuring that workload management is supported in some cases for around the clock SLAs.
It is appropriate for database application development supporting data driven processes, online transaction processing, BI/reports/analytics ... for addressing about any business data processing need I can think of. Oracle Application Express is fantastic for creating beautiful rich user interfaces with support for all major browsers rendering well on a range of devices. It is less appropriate for applications requiring native low level access to device peripherals and is less appropriate for applications that must execute offline without network/internet connection to supporting application and database servers.
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.
Perhaps is our problem, since we haven’t explored it deeply, but I think that a better portability to mobile devices would help the adoption of APEX.
Applications weren’t as light as we thought, and we had to move the APEX server to the same data center where our data base was running, due to performance issues. When we started, we supposed that that situation would not be an issue.
At least in Argentina and Brazil, you can not find as many programmers with experience in APEX as you can find with other technologies.
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.
I felt very comfortable using Oracle Application Express from the start. I designed my data model and quickly developed the basic CRUD pages for master tables. Then I designed the main functionality and was able to test and deploy it in a couple of days work. I will probably share the app with other members of the team and continue adding some features in the short term.
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.
its easy to use as a developer and applications designed using apex are easy and intuitive to use as an end user. Even non-coders can build good applications, the more code you can write the more you can enhance the application but you can get up and running quickly with almost no technical know how.
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.
Very active and knowledgeable community support includes quick and helpful responses from the Oracle employees on the product development team. I've never had to raise an official support request - everything is dealt with via forums and user groups - or via direct emails. The supposrt commuinty is one of the great things about Apex.
Using it on the cloud is really simple, the entire process of configuring and provisioning an Oracle Database takes only a few minutes (less than 10) and then Oracle APEX is already deployed on the database, so you just have to start using it. I would strongly recommend using APEX on Oracle Cloud Free Tier.
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.
Obviously Oracle Application Express cannot replace WebLogic in terms of creating domains but it is not designed to do that. We can use this tool to prototype and later develop a product using the Oracle WebLogic platform. We selected Oracle Application Express due to the ease of learning, and not having to buy licenses to use it.
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!!
Fast response time by processing optimization and cost reduction by reduced CPU utilization. Nowadays, good performance is a necessary condition for the survival of a company and its sustained growth
SQL enhancements are targeted to improve performance, simplify current and new applications, and reduce the development cycle time to market.
A CPU reduction at peak times can immediately reduce our TCO by reducing software costs related to CPU utilization.
Impressive reductions in memory requirements, which used to limit the concurrent database activity
Out-of-the-box savings without changing the database or application
In the mid-size organization, we had a BI tool that had a significant license cost involved. With Oracle back-end we were able to switch to APEX and move all reporting at literally zero cost.
For Oracle PL/SQL users the learning curve is very quick and easy, there are ready templates that you can start with and eventually create complex reports.
You can track authorization and authentication on data editing and usage. High performance as it is native oracle sql codes.
Centralized data capturing, makes your datawarehouse writable for lookup tables or reference tables.
