SPEAKER: More and more companies are looking to unlock business

insights from their data.

But it can be hard to scalably ingest, store, and analyze

that data as it rapidly grows.

Google's enterprise data warehouse, BigQuery,

was designed to make large-scale data analysis

accessible to everyone.

In this series, we'll show you how

BigQuery can help you get valuable insights

from your data with ease.

Ask questions and get answers on "BigQuery Spotlight."

[MUSIC PLAYING]

If you're a developer, data analyst,

or just about anyone else, you're

probably working with data.

If your business has small amounts of data,

you might be able to store it in a spreadsheet.

But as your amount of data grows to gigabytes,

terabytes, or even petabytes, you

start to need a more efficient system like a data warehouse.

That's because all that data isn't very useful unless you

have a way to analyze it.

Traditionally, larger sets of data

mean longer times between asking your questions

and getting answers.

Have you ever needed to wait hours or days for an analytics

report to be run?

BigQuery was designed to handle massive amounts of data,

such as log data from thousands of retail systems or IoT data

from millions of vehicle sensors across the globe.

It's a fully managed and serverless data warehouse

which empowers you to focus on analytics instead of managing

infrastructure.

By design, BigQuery helps you avoid the data silo problem

which happens when you have individual teams

in your company having their own independent data marts.

This can create significant friction between analyzing data

across teams and cause challenges

with data version control.

Thanks to the integration with Google Cloud's native identity

and access management, you can assign read or write

permissions to specific users, groups, or projects,

and keep your sensitive data secure,

all while still collaborating across teams.

Working with data in BigQuery involves three primary parts--

storage, ingestion, and querying.

Google handles running everything else.

BigQuery is a fully managed service,

which means you don't need to set up or install anything.

And you don't require a database administrator.

You can simply log into your Google Cloud project

from a browser and get started.

First, let's talk about BigQuery's storage.

Data is stored in a structured table, which

means that you can use standard SQL for easy querying and data

analysis.

For example, let's say that you have

some data that represents the sales for each of your stores

in the last year.

You could probably use a smaller database for that.

But what if you have thousands of stores?

And what if you want revenue broken up by product SKU

or by region per time period?

BigQuery is perfect for big data because we

manage all that storage and the scaling operations

automatically for you.

Of course, storing the data doesn't

matter if you can't get into BigQuery in the first place.

Thankfully, there are lots of ways

to do that, as BigQuery is integrated

with the rest of the data analytics platform from Google.

You can upload data from Cloud Storage and just streaming

data from Cloud Dataflow, build an ETL pipeline using

Cloud data fusion, import data from a variety of file formats,

or use a combination of all of these.

We'll go over these and more in future episodes

so that you can decide which setup

is right for your data sets.

Once your data is in BigQuery, you're

ready to start answering those questions.

BigQuery supports the same Structured Query Language,

or SQL, that you may be familiar with if you

worked with ANSI-compliant relational databases

in the past.

We'll go over multiple ways to work with data in BigQuery

so that you can choose what's best for your use case.

Plus, you'll be able to share access with other users,

so they can derive insights from your data, too.

Want to skip straight to analyzing some data?

You can bypass the ingestion and storage steps

by analyzing the BigQuery public data sets.

These are third-party data sets which have been made public

for anyone to query against.

Google handles all the storage so that you

can focus on figuring out answers to questions,

like, how does the weather in New York City

affect demand for taxicabs?

In this series, we'll walk you through the play-by-play, some

of the most common tasks in BigQuery,

and share some best practices to help you up your game.

But if you want to get started right now, click on the link

below, and start with the BigQuery sandbox.

The sandbox gives you a free environment to trial BigQuery.

And you can get started by analyzing public data

sets immediately.
