Can someone help me how to do star models, build a cube and dimensions in Pentaho?
Need I install some plugins?
I am looking for tutorials, but the are a lot to pentaho 4.. than don't explain about plugins or ..to Pentaho 5.
Good tutorials are a good idea.
I think you must use Pentaho Schema Workbench. It will exactly do what you want. Refer this documentation they have provided for version 5.4. No need of any plugins if you use this.

We are supposed to make a web-based project using postgres. The topic is library management system, where on a website a user can search whether a book is available in the library, if it is present then where, and so on.
The problem is just that I don't know anything about web development. I do have a pretty good knowledge of sql, but I'm confused a bit in that too, because I don't know if I'll just have to run the queries in my laptop in postgres and link if it "somehow" to the website, or will I have to upload my data on some server (for eg., firebase in case Android development) to be used in my website.
So briefly, I've just two questions:-
How should I start, because I have no idea where to begin with(I do have all the data needed btw)?
About postgres, will the queries run on my laptop or some server?
Please help me with this. Some online resources for the same are way more than just welcome, because I was unable to find any. Thank you!
First of all, you'd take a look at some design pattern in order to learn some theory on how to make (web) apps in the right way. You can visit Martin Fowler's web site and read them.
Once studied, you'd follow my advice. If you've got Java expetise, I'd start by learning Spring Boot, which has every piece you need to achieve your goal. This project follows lot's of design patterns (MVC, Repository, DAO, AOP, IoC/DI...) and lets you follow others (DTO). Anyway, choose the right template engine (I like Thymeleaf) or any other framework (Angular 2...).
Hope it helps.
welcome to development world. When starting out it seems very confusing but it is not that much.
Start slow, there are many tutorials across which helps.. just do a bit of google.
To answer your question :
How should I start, because I have no idea where to begin with(I do have all the data needed btw)?
-- Google simple website with postgres db. For that you will require the database to be installed and a webserver on your machine. All of which will be used when you host the website
About postgres, will the queries run on my laptop or some server?
-- It will run on where you have installed the database..
hope this helps :)
I have my existing BI reporting from the SAP BO software and now I want to migrate everything to MicroStrategy. So is there any way to migrate those reports to MicroStrategy directly or just if I can migrate the dimensions and measures created in SAP BO to Attributes and metrics in MicroStrategy. Please suggest a way to do that effectively.
I did research on this topic on other platforms like on MicroStrategy community and Google also, but all those did not answer my question clearly.
If I remember correctly there was once an internal tool in MicroStrategy to do that, I never used it and from what I remember it was quire rough and still required a lot of manual work.
You can try to read this presentation from MicroStrategy to have an idea about the process and the possible approaches.
Personally I did once a conversion from BO to MicroStrategy, it was possible to reuse most of, if not all, the tables created for Business Object, but in MicroStrategy I created everything from scratch, the design of the dashboards was different to make them more interactive/easy to use.
Of course this approach can appear not feasible with big projects (this is why colleagues were using the above mentioned tool), but I think rebuilding from scratch, with a small scope (small team) and build on it will give the best result in the long run. The main issue here is that this could take time and some times organizations don't want to wait, but this is their problem :)
I have HANA installed in a server (RHEL 6.5) with HANA Studio. Now I want to do some predictive analysis in the data which is stored in the HANA database.
I know that there is a tool "HANA Predictive Analytics" for doing that.
But I do not know where to find if the tool is installed or we have to do it manually?
Any help is appreciated. Thanks in advance
SAP HANA comes with an option to install the Predictive Analysis Library which provides with the backend algorithms for many predictive use cases. These algorithms are available via functions and can be used directly in SQL, in SQLScript or in any other scenario.
Now, typically when people want to do something 'data sciency' they are looking for visualisations etc.
SAP has a solution for that - it's a separate program called "SAP Predictive Analytics" which can leverage the PA Library in SAP HANA.
Sorry, if this reads like a marketing plug, but that's the SAP offering.
If you want to use the SAP HANA PAL w/o additional software, I highly recommend to check out the YouTube videos of the SAP HANA Academy on that topic.
Hope that helps with getting you started.
The PAL documentation (available here) has a section on how to find out whether the PAL is already installed and working, and how to install it if it's not. These topics are covered in chapter 2.
There is also a graphical workflow tool (the Application Function Modeler) that makes your life much easier when you're working with the PAL. It doesn't generate graphical output in the sense of ROC curves and the like, but it gives you a nice overview over your workflow, in much the same spirit as KNIME, SAS Enterprise Miner, SPSS Modeler, and similar tools. So you can avoid using the slightly inconvenient SQL-API of the PAL.
How to include large text description in QlikView Dashboard Reports to ease the visualizations of the users?
Can anybody suggest an example on this ?
Thanks
You can find demonstrations of QlikView Dashboards at http://demo.qlik.com, some of these have similar features to what you are looking for and may be downloaded for free. You can then inspect them to discover how certain features are implemented.
Im using Pentaho for my ETL tool project. Can I have a detailed step by step on how to for the ff.
I want to have a repository for all the sql scripts we are running everyday.
I want to learn how to schedule this routine.
Daily we ran different queries in postgres database and we want it to automate. Can you help me this. I would appreciate your immediate response. Thank you.
tin,
I suggest taking a step back and reading the manual at this point. If you're serious about this, later on you'll be happy you have read it. Once you feel comfortable with the tool, you might want to read this excellent book as well. Do that and all your questions will be answered, promised. You can also drop by the unofficial IRC channel. There are always fine folks from the community and some core developers available to help you. It's channel ##pentaho on irc.freenode.net.
There are no quick way to properly use these tools. They are powerful and will help you do a lot, but they are complex and you will have to figure out how to use them to your advantage and that requires experience. Trust me, I work at Pentaho. =)
