- As of 2023-01:
- Power BI Pro doesn't provide machine learning / artificial intelligence functions
. - Power BI Premium provides machine learning / artificial intelligence functions.
- Starscheme: Separation of fact table and dimension table.
- Fact table ( FACT_xxx, F_xxx ): German w-questions ( who, what, when, amount, rebate.. ), what is relevant for a financial transaction ( buy / sell / contract ).
- Dimension table ( DIM_xxx, D_xxx ): Product ID, product category, country of customer.
- If a customer buys 1000x the same good, you don't want all the 1000 data items in the dimension table.
- Spreadsheet Cell vs. Calculated column vs. Measure.
- In opposite to spreadsheets, BI tools are not based on the “cell” principle, you can just address columns, not single cells .
- Calculated columns require filespace, Measures don't require filespace, as they are calculated in-memory.
- Calculations
Umsatz = 'F_Order Details'[Unit Price] * 'F_Order Details'[Quantity] *(1-'F_Order Details'[Discount]) Einkaufskosten = 'F_Order Details'[Quantity] * RELATED(D_Products[UnitCost]) Gewinn = 'F_Order Details'[Umsatz] - 'F_Order Details'[Einkaufskosten] Datumstabelle = VAR ErsteErfassung = Min(F_Orders[Order Date]) VAR Kalender = CALENDAR(Date(Year(ErsteErfassung),1,1), Date(Year(Now())+1,12,31)) return ADDCOLUMNS( Kalender, "Jahr", Year([Date]), "JahrQuartal", FORMAT([Date], "yyyy-Q"), "JahrMonat", FORMAT([Date],"yyyy-mm"), "JahrKW", COMBINEVALUES("-", Year([Date]), FORMAT(WEEKNUM([Date],21),"00")), "Quartal", FORMAT([Date], "\QQ"), "Kalenderwoche", WEEKNUM([Date], 21), "Monat", FORMAT([Date], "mmm"), "Monat#", Month([Date]), "Wochentag", FORMAT([Date], "ddd"), "Wochentag#", Weekday([Date], 2) )

- Software:
- “QlikView”.
- The free QlikTech International AB "Download QlikView Personal Edition. Experience the power of Qlik on your personal computer", QlikTech International AB "Seeing is Believing. Downloaden Sie QlikView noch heute!" for Win64 “Qlik lädt Sie dazu ein, sich die QlikView Personal Edition downzuloaden. Diese ist keine Testversion, sondern eine komplette Version unserer leistungsfähigen Business-Discovery-Software”.
- “QlikView 12” is a local server application for Win64 computers, with a rich client applications for Win64.
- “QlikView 11” was the latest edition with both Win64 and Win32 server and client applications.
- “QlikView” is more complex than “Qlik Sense”, i.e. for domain experts with good software programming skills.
-
- Accompanying website QlikView 11 for Developers.
- Application developers need both the “QlikView” application server and rich client.
- Important commands:
- By “File / Edit Script” you may create and modify the query code to access and filter the data of the project.
- By “File / Table Viewer” you may view the table structure of the project.
- With “QlikView”, you must import each single spreadsheet worksheet, e.g if a spreadsheet file consists of 3 worksheets, you must do 3 manual imports.
- “Qlik Sense”.
- The free QlikTech International AB "Download Qlik Sense Desktop. Experience the power of Qlik on your personal computer", QlikTech International AB "Download von Qlik Sense Desktop. Kostenfreie Self-Service Datenvisualisierung und Discovery - vertrauen Sie Ihrer Intuition" for Win32 or Win64 - “Qlik Sense Desktop ist eine kostenfreie Windows Desktop Applikation, mit der Einzelpersonen über Drag-and-Drop interaktive Datenvisualierungen, Reports und Dashboards aus verschiedensten Datenquellen erstellen und teilen können. Gewinnen Sie in nur 5 Minuten mehr Einsichten in Ihre Daten!”.
- “Qlik Sense” is a local server application for Win64 computers. You may operate with the desktop client “Qlik Sense Desktop” - which is a modified browser - or may use a standard Internet browser instead, by calling URLs:
- Application developers just need the “Qlik Sense” (enterprise) application server, on which the application is published.
- “Qlik Sense” is more simple than “QlikView”, i.e. for domain experts without software programming skills.
- I was told by sales staff in 2016, that new customers prefer to order “Qlik Sense” prior to “QlikView”.
- The online service QlikTech International AB "Join Qlik Sense Cloud. Experience the power of Qlik on your personal computer" with free entry-level account offer.
- With “Qlik Sense”, you may import a spreadsheet at once, e.g if a spreadsheet file consists of 3 worksheets, you must just do one import.
- Experts told me about filtering:
- Filters work as associative logic in context.
- A number of filters may may be applied to an Qlik application.
- If you apply data filtering to the Qlik data model, it is applied to all Qlik applications which use it.
- If you apply data filtering to a Qlik application, it is applied to the single Qlik application.
- Design rules for dashboards:
- Simple rule:
- Left side = “Filter”.
- Right side = “Information”.

- But Google Play refuses installation “Your Device isn´t compatible with this version” on simulator Bluestacks with “Android 4.4.2”.
Resources
- “Microsoft Power BI” is a dashboard tool, not a reporting tool!
- It is powered by “Microsoft SQL Server Analysis Services (SSAS)”.
- It is now easy to catch data from HTML pages ( e.g. data tables of Wikipedia ).
- Data visualisation:
- Built-in graphics ( by a graphics engine similar / identical to that known from Micrsoft Excel, Microsoft SQL Server Reporting Services and Microsoft SQL Server Analysis Services ).
- There is an API by which third parties may offer own visualisations.
- Indeed with Microsoft Excel 2016, you may create the same dashboards, but you can´t publish it on the web.
- You may save “Microsoft Power BI Desktop” as in single ”.pbix” files. Experts told me, that for saving a project, the software needs 3 times of the RAM memory as needed for the loaded data. So it might be that you may load big data, but are not able to save it. In general, this might not be a problem with the 32-bit edition ( on Windows PCs with 2 or 3 GByte of RAM ), but also with the 64-bit edition ( i.e. a project may be saved on a Win64 computer with 16 GB RAM, but not on a Win64 computer with 4 GB RAM ).
- You might create test cases ( e.g. at business intelligence trainings ) with “Microsoft Power BI”, as alternative to NBI.
- NBi, GitHub "Seddryck/NBi", CodePlex "NBI" - “Testing framework for Microsoft Business Intelligence platform”.
- “Microsoft Power BI Desktop” also supports the “M” and “DAX” query languages, by the “Advanced Editor” ( “Home / Edit Queries ( = Query Editor ) / Advanced Editor” ).
- If you install “Microsoft R” prior to “Microsoft Power BI Desktop”, you may use “R” for data processing and graphical reporting → See Mathematical Engineering.
- I was told by experts, in 2016-03:
- Now legacy versions of “Microsoft Power BI Desktop” were able to process 10.000 datasets for visualisation.
- Current versions of “Microsoft Power BI Desktop” were able to process 10.0000 datasets for visualisation.
- With “R” called by “Microsoft Power BI Desktop”, you may visualize 150.000 datasets.
Commercial Editions of Microsoft SQL Server with BI Support
Power BI Gateway - Personal
The Tool
Documentation
Concept
- To get a BI report, connect with a client ( Internet browser, smartphone app,..) to the “Microsoft Power BI” cloudservice. The basic “Power BI” account is free.
- By this, you may access any cloud document.
- The cloud servce may access a registered onpremise Windows server at your ( the datacenter of your ) company, if the computer runs a free “Power BI Gateway - Personal” service, by a VPN connection.
- Experts told me, that the free VPN service shipped with Windows is not under development for some time. Therefore it isn´t very advisable to use it in production environments.

- You may create a copy of a Jupyter notebook put on Google Docs, by “File / Save a copy in Drive”.
- But its most easy to transfer additional data files by downloading them on your local terminal ( PC with browser ), and to upload it into the copied Jupyter Notebook.
- You might use “Files / Mount Drive” to create the code
from google.colab import drive drive.mount('/content/drive')

-
- “Azure Event Hubs provides highly scalable publish-subscribe event ingestors. An event hub can collect millions of events per second, so that you can process and analyze the massive amounts of data produced by your connected devices and applications”.
- “Together, Event Hubs and Stream Analytics provide an end-to-end solution for real-time analytics. Event Hubs lets you feed events into Azure in real-time, and Stream Analytics jobs can process those events in real-time”.
- “For example, you can send web clicks, sensor readings, or online log events to Event Hubs. You can then create Stream Analytics jobs to use Event Hubs as the input data streams for real-time filtering, aggregating, and correlation”.
-
- “In a real-world scenario, you could have hundreds of these sensors generating events as a stream. Ideally, a gateway device would run code to push these events to Azure Event Hubs or Azure IoT Hubs. Your Stream Analytics job would ingest these events from Event Hubs and run real-time analytics queries against the streams. Then, you could send the results to one of the supported outputs”

- “3.4 The Eliteness Model and BM25. We now re-introduce term frequencies into our model... We suppose that for any document-term pair, there is a hidden property which we refer to as eliteness. This can be interpreted as a form of aboutness: if the term is elite in the document, in some sense the document is about the concept denoted by the term. Now we assume that actual occurrences of the term in the document depend on eliteness, and that there may be an association between eliteness (to the term) and relevance (to the query)”.

Die Volltextrecherche dient daher dem Auffinden, Entdecken und Extrahieren unbekannter, nicht trivialer und wichtiger Informationen aus großen Mengen von unstrukturierten Texten/Dateien und ist somit auch ein wichtiger Teilbereich des Text Mining. Sie ist eine Sofortlösung, um für eine konkrete Fragestellung auf Systeme wie Dokumentenmanagement und Data-Mining verzichten zu können”.
