Trying SAP Lumira

These are my observations. I cannot help myself not to compare it to Tableau as Tableau has so far been the easiest and with best business benefits in my mind and heart.

I tried Lumira Personal Edition which is free and i tried to do simple bar chart, geo chart (including Estonian) and thus covered some of the functionality

Data connection and metadata

I tried the same data source (Excel 168 000 rows) as I used with Tableau

I was smiling and happy to work, but unfortunately i got error "Data acquisition has failed (HDB 00101)". I tried  hiding some fields, but still got this error and even  googled but didn't find any relevant information. Eventually after removing some fields I was ready to go forward. Little bit it remined me Business Objects and all error descriptions - often they didn't tell very precisely what is wrong

I was happy that the user interface seemed friendly and not overwhelmed .

There is the same panels like Tableau Measures and Dimensions. Good!

One thing I noticed, that the time hierarchy must be created by yourself, it is not automatically there. And when you create it by yourself, then its four stage. Tableau has many more stages and automatic hierarchy                                                                                                                                           Of course you can change data type but and a little bit format, but that's all. You cannot define like automatic colors, sorting and so on. This means every time more time to do that on every visualization


Charts

When Tableau made this understanding chart, then Lumira cannot handle this and as there are now scroll-bars, it is all not meaningful  at all

Adding top values (didn't find though how user can change this) and then this picture makes sense

Didn't find any easy place to create custom hierarchies

Funny thing was this, that I couldn't to any Undo? Maybe it was in my computer, but it really is disadvantage, when developing my analysis

Wanted to calculate difference in minutes and found that there are really small capability of functions and no Datediff function to calculate difference in minutes

Didn't see also any trendline and forecasting options

You cannot choose area with your mouse and select only data interesting to you, you cannot see underlying data, you cannot edit data, etc. You cannot change colors on every graph on desktop edition and specify that with Red value use Red color and etc.

You can merge data from different sources and it seems quite fast and there are storyboards like in Tableau

On dashboard you have ability to add visualizations and filters. Didn't find the ability to click on chart and filter - but I guess this must be available and I didn't just find it ?

Didn't also find the ability to change tooltips?

Geospatial analysis

Lumira makes own suggestions which data might be geographic (just like Tableau) and you can define yourself

It shows which data is not connected, but couldn't find that I can myself define or edit data so that all data would be connected

You can use names to link data to maps or give longitude and latitude for Lumira

Geo chart was ok, but couldn't add more functionality to it, like different colors, edit bubble sizes

Also graphics was not so advanced - very square like



Conclusion

Lumira is ok, you can build visualizations and do some analysis. But functionality is not so great when compared with Tableau and seems limited in many areas. I think they have done a good start to move forward on offering visual analysis tool, but there is a long way to go ahead.

I think when using Lumira on everyday bases, then you'll find some other ways to overcome these limits

Proovides reaalselt kasutada QlikView'd, MicroStrategy't ja Spotfire'it

QlikView

Installeerimine oli lihtne.

Esialgu jahmatas see, et esialgne ekraan oli tühi ja natukene uurides selgus, et peamiselt kõik toimingud erinevate menüüpunktide all, mida oli ikka korralikult palju.

Lõpuks sai wizardi abil ühendus andmetega tehtud ja esimene diagramm ka valmis.
Üks tähelepanek, mida olin enne ka erinevates foorumites lugenud - üks viisard teise otsa. Tableaul on hea, et kohe näen, kui midagi teen. QlikView näib aga olevat üles ehitatud ikkagi viisardite peale.

Graafikute kvaliteet ka veidi ehmatas, tunduvad sarnased Excelile, peab natukene vaeva nägema, et ilusat pilti ette saada

Kuigi jah, tundub, et Tableaul on eelis arendamise seisukohalt, et pakub andmeallikate scriptide erinevat muutmist, seal erilist drag-drop funkstionaalsust pole

Mis on muidugi mugav on see, et automaatselt on erinevad diagrammid omavahel seotud ja filtreerides ühel lehel, filreeritakse ka teisel aga samas kas see vaikimisi peaks alati peal olema ja kui tahan muuta, et oleks filter ainult osadele aobjektidele määratud?

Erinevaid suvandeid diagrammil puhul on muidugi palju, nende selgeks õppimine ja leidimine võtab vist ikka korralikult aega. Samuti olemas nn seostatud otsingu funktsionaalsus.

Qlickview on ikkagi ennekõike mõeldud arendajale (kuigi eks ka arendajal kulub ikka aega, et sellega toimetada ja miskit ilusat valmis saada). Hea visuaalse analüüsi tegemise tööriist see hetkel küll ei ole, kuna viisardite süsteem tühistab selle efekti. Samuti visuaalse poole nn ilusaks tegemine võtab omajagu aega.
Erinevaid võimalusi muidugi on päris palju ja arendajale võib see tööriist olla kindlasti meeltmööda

QlikView.Next peaks mitmed puudujäägid kõrvaldama - kas kõrvaldab?


MicroStrategy, Spotfire

Neid vaatasin pisteliselt. 
MicroStrategy - Visuaalne ehk siis ka visuaalse analüüsi vahend. Vähem võimalusi kui Tableaul ja veidi kohmakam, aga esialgse vaate saab suhteliselt ruttu kätte
Spotfire - ka visuaalsem analüüsi tarkvara, rohkem sarnasem Tableaule, rohkem võimalusi, statistiline pool päris hea, automaatselt pannakse kaasa kõikvõimalike filtrite valik. Olemas palju erinevaid suvandeid, mida saab visuaali puhul muuta. Spotfire tundub päris hea, dashboardi funktsionaalsus veidi limiteeritum. Väga sarnane tableaule, andmete ühendamine einevatest allikatest ka olemas
