Unlike purpose-built data storage systems, a data lake can be used to dump data in its original form. This data usually remains unsupervised.
A major cyber attack on a data lake could have immense consequences for any of us. And the damage could be felt anywhere from banking to the healthcare sector.
Analysing big data can tell us how a big city ticks, including where suitable housing and jobs are, and how best to get to them.
We have learnt to be wary of big data, but it can also be your friend: one platform combines and analyses data about housing, jobs and transport to reveal very useful information about living in Perth.

Roughly one-third of the league won't be trying to win this season. What's fueling this trend?
Working together, people and technology companies can make a lot of progress.
Amazon, Facebook and Google have lofty goals for their effects on global society. But people around the world are still waiting for the positive results. Here's what the tech giants could do.
Often the value of data science lies in the work of joining the dots.
Data science can map where street harassment is most prevalent, ensure public bins don't overflow and identify neighbourhoods with poor fire safety standards in the home.
Man and machine.
Artificial intelligence and data analytics are transforming the practice of law.
Cities are growing vertically as well as horizontally, so infrastructure needs to ensure people can move up and down as well as across the city.
Cities are expanding upwards and downwards, as well as outwards. With urban density also increasing, moving people efficiently around the city, often using ageing infrastructure, is quite a challenge.
The data you create when using the internet can actually be used to discriminate against you.
Noise around extreme practices drowns out how data analytics is being used in everyday ways. To really consider control of our data we must look beyond Cambridge Analytica.
Cambridge Analytica CEO Alexander Nix.
The privacy backlash over Cambridge Analytica and Facebook may lead to explosive consequences for academics.
The global market for predictive analytics is growing.
Business managers often rely on predictive algorithms to make recruiting decisions that affect a company's bottom line. But these kinds of algorithms aren't really "predictive" at all.

July 30 marks the United Nations’ World Day Against Trafficking in Persons. How can computer scientists help combat this problem?
Collecting the data comes first, but then you have to analyze the data.
Any field that collects and analyzes data relies on statistical techniques to make sense of it all. Modern, more accurate methods should supplant the old ways... but in many cases, they haven't yet.
In one regard, lockout laws have succeeded in decreasing crime. But take a step back to see a city-wide perspective, and there are many other issues to consider.
Policy changes such as the 'lockout laws' have had profound impacts on inner Sydney nightlife. Transport data help us see whether these have caused problems to spill over into neighbouring areas.
There are reasons to believe the promise of people analytics may not live up to the hype.
Despite its promises, people analytics has serious ethical implications and can adversely affect organisations and how people are treated at work.
When they’re talking, what are they really telling us?
Candidates and campaigns are analyzing voters endlessly this election season. But the internet allows us to turn the tables and obtain a wide variety of data about them, too.
An increasingly diverse array of geospatial, network and time-series data is being used to generate new perspectives and insights. Here we see air traffic in England and Wales visualised over satellite images.
People in all manner of professions from economists and real estate agents to stockbrokers and doctors are beginning to recognise the huge potential and power of unconventional data.
Who’ll be the next president of the United States – Donald Trump or Hillary Clinton?
The Australian census is just one way to gather data on people. We also freely give out information in other ways that can be used to study many things, and maybe even predict an election result.
Each tweet that relays an emotion, opinion or idea joins millions of others.

On Twitter's 10th birthday, we look at how researchers have used the platform for a range of studies, from predicting the next flu outbreak to identifying the happiest city in America.
