Overview

Data Catalog is a fully managed, scalable metadata management service within Dataplex.

It offers a simple and easy-to-use search interface for data discovery, a flexible and powerful cataloging system for capturing both technical and business metadata, and a strong security and compliance foundation with Cloud Data Loss Prevention (DLP) and Cloud Identity and Access Management (IAM) integrations.

BigQuery is an enterprise data warehouse that enables super-fast SQL queries using the processing power of Google's infrastructure.

Simply move your data into BigQuery and let us handle the hard work. You can control access to both the project and your data based on your business needs, such as giving others the ability to view or query your data.

Using Data Catalog

There are two main ways you interact with Data Catalog:

• Searching for data assets that you have access to.
• Tagging assets with metadata.

Data Catalog use case

Imagine you are a data engineer in your company. It is your job to ensure all datasets can be easily discovered and used by colleagues, such as data scientists or business analysts. When a new dataset comes in, you annotate it with important information—this could be whether or not it contains PII data, who owns the dataset, how many rows the dataset contains, etc.

You can annotate this information by adding tags to your dataset and tables. Data Catalog allows you to create tag templates to let you define what kind of attributes you want to tag. This allows you to easily access, map, and discover pertinent information from your datasets and tables.

What you will learn

In this lab, you will learn how to:

• Enable the Data Catalog API so that you can use this service in your Google Cloud project.
• Create a dataset with BigQuery.
• Copy a public New York Taxi table to your dataset.
• Create a Data Catalog tag template.
• Tag your newly created table with the newly created tags.

Prerequisites

Setup and requirements

Before you click the Start Lab button

Read these instructions. Labs are timed and you cannot pause them. The timer, which starts when you click Start Lab, shows how long Google Cloud resources are made available to you.

This hands-on lab lets you do the lab activities in a real cloud environment, not in a simulation or demo environment. It does so by giving you new, temporary credentials you use to sign in and access Google Cloud for the duration of the lab.

To complete this lab, you need:

• Access to a standard internet browser (Chrome browser recommended).

• Time to complete the lab—remember, once you start, you cannot pause a lab.

How to start your lab and sign in to the Google Cloud console

1. Click the Start Lab button. If you need to pay for the lab, a dialog opens for you to select your payment method. On the left is the Lab Details pane with the following:

   • The Open Google Cloud console button
   • Time remaining
   • The temporary credentials that you must use for this lab
   • Other information, if needed, to step through this lab

2. Click Open Google Cloud console (or right-click and select Open Link in Incognito Window if you are running the Chrome browser).

   The lab spins up resources, and then opens another tab that shows the Sign in page.

   Tip: Arrange the tabs in separate windows, side-by-side.

   Note: If you see the Choose an account dialog, click Use Another Account.

3. If necessary, copy the Username below and paste it into the Sign in dialog.

   {{{user_0.username | "Username"}}}

   You can also find the Username in the Lab Details pane.

4. Click Next.

5. Copy the Password below and paste it into the Welcome dialog.

   {{{user_0.password | "Password"}}}

   You can also find the Password in the Lab Details pane.

6. Click Next.

   Important: You must use the credentials the lab provides you. Do not use your Google Cloud account credentials. Note: Using your own Google Cloud account for this lab may incur extra charges.

7. Click through the subsequent pages:

   • Accept the terms and conditions.
   • Do not add recovery options or two-factor authentication (because this is a temporary account).
   • Do not sign up for free trials.

After a few moments, the Google Cloud console opens in this tab.

Note: To access Google Cloud products and services, click the Navigation menu or type the service or product name in the Search field.

Activate Cloud Shell

Cloud Shell is a virtual machine that is loaded with development tools. It offers a persistent 5GB home directory and runs on the Google Cloud. Cloud Shell provides command-line access to your Google Cloud resources.

1. Click Activate Cloud Shell at the top of the Google Cloud console.

2. Click through the following windows:

   • Continue through the Cloud Shell information window.
   • Authorize Cloud Shell to use your credentials to make Google Cloud API calls.

When you are connected, you are already authenticated, and the project is set to your Project_ID, . The output contains a line that declares the Project_ID for this session:

gcloud is the command-line tool for Google Cloud. It comes pre-installed on Cloud Shell and supports tab-completion.

3. (Optional) You can list the active account name with this command:

4. Click Authorize.

Output:

5. (Optional) You can list the project ID with this command:

Output:

Task 1. Enable the Data Catalog API

1. From the navigation menu, select APIs and Services > Library.

2. In the search bar, enter in Data Catalog and select Google Cloud Data Catalog API.

3. Then click Enable.

If you run into the following error after trying to enable the Data Catalog API:

1. Click Close.
2. Refresh your browser tab.
3. Click Enable again.

The Data Catalog API should be successfully enabled:

Open the BigQuery console

1. In the Google Cloud Console, select Navigation menu > BigQuery.

The Welcome to BigQuery in the Cloud Console message box opens. This message box provides a link to the quickstart guide and the release notes.

2. Click Done.

The BigQuery console opens.

Task 2. Create a dataset

1. In the left navigation pane of BigQuery, click on view actions next to your project id, then click CREATE DATASET.

2. In the Create Dataset dialog:

• For Dataset ID, enter demo_dataset

• For Data location, select US (multiple regions in United States).

3. Then click Create dataset.

Click Check my progress to verify the objective. Create a dataset

Task 3. Copy a public New York Taxi table to your dataset.

1. From the left-hand panel, click + ADD > Public datasets.

2. In the search bar, enter in NYC TLC Trips and click on the result that appears:

For this lab, you will be using a table from this dataset which contains NYC yellow cab trip data from 2018.

3. Click out of the side panel to close it as soon as you're ready to continue.

4. Copy the tlc_yellow_trips_2018 table by running this command in your Cloud Shell panel. Click Authorize.

The previous command used the bq command line tool to copy the public table into your project and organized it in the demo_dataset you created earlier.

5. Refresh your BigQuery browser page.

6. Confirm that the trips table is listed in your demo_dataset.

You will add Data Catalog tags to the table in the next section.
