Overview

What is Power BI

Microsoft Power BI is a collection of software services, applications, and connectors that work together to turn related and unrelated sources of data into coherent, visually immersive and interactive insights. With its simple user interface and availability as part of the Office 365 package, Power BI has become a standard business intelligence/data visualization tool of OCHA.

Whether your data is a simple Microsoft Excel workbook, or a collection of cloud-based and on-premises hybrid data warehouses, Power BI lets you easily connect, clean, and model your data without affecting the underlying source. The broad catalogue of built-in and add-on visualization options allows creating neat and easy-read summaries of both simple and complex data. Finally, Power BI allows sharing of the final work with either public or restricted audiences.

The components of Power BI

Power BI consists of a Microsoft Windows desktop application called Power BI Desktop, an online SaaS (Software as a Service) called the Power BI service, and mobile Power BI apps available for phones and tablets.

These three elements — Desktop, the service, andthe Mobile apps — are designed to let people create, share, and consume business insights in the way most convenient for their role and goals.

Workspaces

Workspaces are containers for dashboards, reports, datasets, and dataflows in Power BI. There are two types of workspaces: My workspace and workspaces.

  • My workspace is the personal workspace for any Power BI customer to work with your own content. Only you have access to your My workspace. You can share dashboards and reports from your My Workspace. If you want to collaborate on dashboards and reports, or create an app, then you want to work in a workspace.

  • Workspaces are used to collaborate and share content with colleagues. You can add colleagues to your workspaces and collaborate on dashboards, reports, and datasets. With one exception, all workspace members need Power BI Pro licenses.

Workspaces are also the places where you create, publish, and manage apps for your organization. Think of workspaces as staging areas and containers for the content that will make up a Power BI app. So what is an app? An app is a collection of dashboards and reports built to deliver key metrics to the Power BI consumers in your organization. Apps are interactive, but consumers cannot edit them. App consumers, the colleagues who have access to the apps, do not necessarily need Pro licenses.

Complete the License and Work Space Request form to request Pro licenses and Premium workspaces. To optimize the efficient use of licenses in OCHA, licenses that are not used for four months or longer will be deactivated if no longer needed.

Tips

  • Use the PCodes and ISO codes to connect different datasets. Wherever possible, the most convenient way to connect two or more different datasets, is using the PCodes. When using other attributes such as names name of a country, district or settlement, there is a risk that the spelling is not exactly the same across the datasets, thus creating a risk of missed links.

  • Pay attention to the column data type. For correct display of numeric data in the visuals, the data type should be set as “Integer” or “Decimal”. If set as “Multiple”, it is not possible to perform mathematical functions (such as SUM, DIVIDE, MULTIPLY) with the data.

  • Use the Power Query tool to create aliases. Ever come across with column or attribute names such as HHs_Female_U18_1-3_PWD_Yes or potableWaterPerHhWithIdpStatusBaselineApril2020potableWaterPerHhWithIdpStatusBaselineApril2020? While technically necessary when using KoBo or other MDC tool, such names tend to be inconvenient or even unreadable to the end users. Generally speaking, the end users prefer to see standard spacing instead of camel cases or underscores used by KoBo or other similar tools. Hence, where necessary, you can use the Power Query to create duplicate columns with aliases and thus, increase increasing the overall user experience.

  • Leave an “expansion space” for your visualizations. Especially in large-scale sudden onset disaster situations, the figures tend to grow in a rapid pace. In addition to the absolute figures, the number of categories is likely to increase: more districts, more distinct groups of people affected, more response organizations coming into play… . The increasing number of figures and categories normally means further population of the visualization elements, whether in a map, chart or table formats. Accordingly, in the very early phases of a disaster, do Do not squeeze your visuals into a too small space, but make sure that the visuals will remain readable and meaningful even with the rapid changes of the situation. The same applies to the map elements: check that the zoom level of the map will expand as new geographical areas are being covered.

  • Consider the strengths and weaknesses of each map tool option. Power BI providers provides several different tools to create maps: the built-in location map, filled map and shapemap along with the add ins from MapBox and ArcGIS. While each tool comes with certain technical and visual advantages, each of them also has certain limitations. Please see refer to the Mapping Map visualization in Power BI documentation page for full information about the best use cases for each map tool.
