A power BI governance allows proper management of business and enterprise. Pixabay

Over the past four years, Microsoft Power BI has proved to be the key to transforming the business intelligence landscape. Both small and large organizations have benefitted from this tool, enabling business leaders to analyze quickly, find new insights, and act based on these insights.

Power Bi governance overshadows the voice of reason on how best to address planning, deployment, and management of insights. To implement Power BI governance, the first thing you need to decide is what the delivery approach of the project will be.

A delivery approach dictates the way reports will be made available, and most importantly assigns responsibility to everyone. At its core, an approach will define where the responsibilities of IT stop, and that of business begins. There are three approaches used for Power BI implementations. Read on to verse yourself with these three approaches.

Business-led Self-Service BI

In this kind of approach, business users have the most involvement and control. It incorporates many non-standardized, non-governed data sources. There’s an inclusion of enterprise-governed sources. However, they aren’t the primary source of data.

The advantage of these kinds of implementations is flexibility. This flexibility stems from business users controlling both datasets and the visualization layer.

Given that the most significant impact is that the business units must take ownership and offer support. This approach requires skilled experts. A qualified and technically capable business team brings it to a proper conclusion.

IT-Managed Self-Service BI (Hybrid)

In this approach, business users use Power BI as a reporting layer on top of a controlled and standardized Corporate DWH. The IT organization’s BI team is responsible for creating and maintaining the dataset. However, certain business users with Power BI Pro licenses create reports and dashboards for consumption by other users.

The business further owns the reports build on top of the data. The advantage of this approach is that both layers can use their release cycle. Therefore, the development cycle isn’t held back by the often slower database/data warehouse development cycle.

Corporate BI

Also known as Enterprise reporting, in Corporate Bi, the IT team owns these kinds of Power Bi Governance implementation. The IT team in this approach is responsible for all layers, starting with the data and ending with the reports.

Corporate BI, however, structured and trustworthy in comparison to the rest of the Power BI governance implementations; it will often have a slower development cycle. It also requires dedicated IT personnel.

The chosen approach helps set the level of business involvement, which further dictates the kind of power bi governance that the project needs. You have to be actively involved in your business to understand the exact measures needed to improve operations.

It’s important to note that it is okay to employ multiple approaches. Given that each project may have different requirements and user communities requiring different approaches, using multiple approaches in such a scenario is the most suitable thing to do.

A good example where multiple approaches may come in handy is in a scenario where a self-service report becomes widely used and eventually considered business-critical. In such a case, it is advisable to switch to a manageable approach.

Organizations can choose to deliver and manage their Power BI Governance through IT and standard project workflows. They can also further empower other business users to adopt self-service BI tools offered by credible organizations such as EPC Group that offer consultations as well.



Bangladesh over the years show that the state has failed in its duty to protect minorities

If humanity is hurt, God is hurt.

Religion without compassion might give way to hatred. Compassion with a "self-interest" motive is completely irreligious. But of late, some of the religions have departed from those basic human values. Love and compassion are for only those who follow their "specific" faith. Very sadly, the religions are up as trading commodities in the world of proselytization. Better preachers attract more followers. Of course, no issue if they are not vying for their religious "supremacy". But the ground reality is utterly different. The claim for exclusive supremacy has become the first commandment --- a real bone of contention among the existing religions. In the name of religion, we have polluted our minds. we have corrupted our souls. We have also gone so much astray that God must have now shut his gateway to heaven!

Planning a family vacation is an excellent way through which the whole family can step away from their daily life and have fun. You can find many destinations for a family vacation, but there is no place that can beat Aruba.

Milky Way galaxy as seen from Chitkul Valley

NASA's Chandra X-ray Observatory has for the first time spotted signs of a planet transiting a star outside of the Milky Way galaxy, opening up a new avenue to search for exoplanets at greater distances than ever before.

The possible exoplanet -- or planets outside of our Solar System -- candidate is located in the spiral galaxy Messier 51 (M51), also called the Whirlpool Galaxy because of its distinctive profile, NASA said in a statement.

Astronomers have, so far, found all other known exoplanets and exoplanet candidates in the Milky Way galaxy, almost all of them less than about 3,000 light-years from Earth.

An exoplanet in M51 would be about 28 million light-years away, meaning it would be thousands of times farther away than those in the Milky Way, NASA said.

"We are trying to open up a whole new arena for finding other worlds by searching for planet candidates at X-ray wavelengths, a strategy that makes it possible to discover them in other galaxies," said Rosanne Di Stefano of the Center for Astrophysics at Harvard and Smithsonian (CfA) in Cambridge, Massachusetts, who led the study.

The findings are published in the journal Nature Astronomy.

The exoplanet candidate was spotted in a binary system called M51-ULS-1, located in M51. This binary system contains a black hole or neutron star orbiting a companion star with a mass about 20 times that of the Sun. The X-ray transit they found using Chandra data lasted about three hours, during which the X-ray emission decreased to zero.

Based on this and other information, the team estimates the exoplanet candidate in M51-ULS-1 would be roughly the size of Saturn and orbit the neutron star or black hole at about twice the distance of Saturn from the Sun.

The team looked for X-ray transits in three galaxies beyond the Milky Way galaxy, using both Chandra and the European Space Agency's XMM-Newton. Their search covered 55 systems in M51, 64 systems in Messier 101 (the "Pinwheel" galaxy), and 119 systems in Messier 104 (the "Sombrero" galaxy).

However, more data would be needed to verify the interpretation as an extragalactic exoplanet. One challenge is that the planet candidate's large orbit means it would not cross in front of its binary partner again for about 70 years, thwarting any attempts for a confirming observation for decades, NASA said.

Named in honor of the late Indian-American Nobel laureate, Subrahmanyan Chandrasekhar, the Chandra X-ray Observatory is the world's most powerful X-ray telescope. It has eight times greater resolution and is able to detect sources more than 20-times fainter than any previous X-ray telescope.

Known to the world as Chandra (which means "moon" or "luminous" in Sanskrit), Chandrasekhar was widely regarded as one of the foremost astrophysicists of the twentieth century. (IANS/JB)
