“Big data” lives up to its name：We produce 2.5 quintillion bytes(字节) of data every day through the digital connections that link people，objects，and devices.Every email，text，post，online search and doctor's visit contribute to big data. 1

Many believe it is.Stores are using it to improve our shopping experience. 2 In the United States，Macy's department store credits big data with improving their customer satisfaction and helping to increase sales by 10 percent.

Banks are also putting quite a lot of money into big data. 3 One area to benefit is customer service，where valuable information collected is supporting speedier decisions on loans(贷款) and credit while providing better protection against theft and even overspending.

Health care is also seeing a marked difference.Data collection is helping to reduce preventable deaths，improve quality of life，predict and cure diseases. 4 Big data searches for patterns to predict how cancers will behave and recently led to the breakthrough discovery that a commonly used antidepressant(抗抑郁剂) has the potential to help find a cure for lung cancer.

Big data is still just getting started，but it already influences almost every area of our lives—mostly attempts to make them better.By 2021，there will be 200 billion connected devices. 5 If computational power and data scientists can keep pace with such growth，the potential for big data to make an even bigger difference is huge.

A．It's even used in cancer research.

B．But is big data really making a difference?

C．Why is big data important to your business?

D．Over $20 billion were spent on data analysis in 2016.

E．Without big data analysis，companies are blind and deaf.

F．And we're predicted to produce 1．7 million bytes of data per person，per second.

G．Data analysis enables stores to predict popular products and ensure competitive pricing.
