How to Work with Strings in Google BigQuery

Organizations nowadays produce a massive amount of data, simply storing and organizing, which is not enough and serves no purpose. It, therefore, becomes essential for businesses not just to collect and store the data but also to analyze it to derive valuable business insights.

Still, there comes a challenge of managing, maintaining, and analyzing these exponentially growing data using the outdated data warehouse technologies and here comes the role of Google BigQuery, one of the well-known and widely accepted Cloud-based Data Warehouse Applications, which allows you to trawl through vast amounts of data and find the correct data for analysis.

It offers various functions such as BigQuery Create Table, which helps store the records, BigQuery Substring, which eases down the complex calculations, and many others.

In this article, we will introduce you to Google BigQuery and its key features? We will also have an overview of the different BigQuery String Functions and BigQuery Substrings and how to work with them.

1. What is Google BigQuery?

Google BigQuery is a cost-effective enterprise data warehouse solution and part of Google Cloud’s comprehensive data analytics platform for business agility.

It helps businesses manage and analyze the data with the help of inbuilt features like Machine Learning, Business Intelligence, and Geospatial Analysis.

Google BigQuery’s serverless architecture allows high-scale operations and execution of SQL queries over large datasets.

It is an enterprise-ready cloud-native data warehouse that covers the whole analytics ecosystem, including ingestion, processing, and storage of data, followed by advanced analytics and collaboration, enabling scalable analysis of the stored data.

2. Key Features of Google BigQuery

Key Features of Google BigQuery

Given below are some of the key features of Google BigQuery: –

Scalability – Google BigQuery is quite elastic in that it manages a vast amount of data and allows upscale or downscale per demand.
Automated Data Transfer – Google BigQuery supports automated data transfer through the BigQuery Data Transfer Service, which automates data movement into BigQuery regularly.
Real-Time Analytics – Google BigQuery facilitates the analysis of high-volume data in real-time.
User-Friendly Interface – BigQuery is a highly user-friendly platform and requires just a basic understanding of SQL commands, ETL tools, etc.
Multicloud Functionality – Multicloud Functionality is another feature of Google BigQuery which allows data analysis across multiple cloud platforms. BigQuery can compute the data at its original location without moving it to different processing zones.

3. BigQuery String Functions

Strings are a crucial part of the dataset whose manipulation and transformation significantly impact your analysis. There are various functions to modify and transform the Strings in Google BigQuery. Let us have a look at some of the essential BigQuery String Functions: –

a) CONCAT –

The CONCAT function helps to combine two or more strings to provide a single result. Here all the values must be Bytes or Data Types; if any of the input arguments is null, then the function will return the null value.

Syntax: –

SELECT
CONCAT(‘A’, ” “, “B”)

b) TRIMMING –

The TRIMMING function removes any particular character from the String. Trimming operations are of three types: –

c) TRIM (value1[, value2]):

TRIM removes all the leading and trailing characters that match value2. In case no character is specified, whitespaces will be removed by default.

d) LTRIM (value1[, value2]):

LTRIM Function removes the character specified from the left, and similar to the TRIM Function, if a character is not defined, it will remove the whitespaces by default.

e) RTRIM (value1[, value2]):

RTRIM Function removes the character specified from the right side, and again if no character is defined, then whitespaces will be removed by default.

Example: –

SELECT
‘Original String_’,
TRIM(‘ Original String_’) AS trimmed,
LTRIM(‘ Original String_’) AS left_trim,
RTRIM(‘ Original String_’, “_”) AS right_trim

f) REPLACE –

The REPLACE function can replace all the substrings within a string with new substrings.

Example: –

SELECT complaint_description,REPLACE (complaint_description,’Coyote’,’doggy’)as replaced_value FROM `bigquery-public-data.austin_311.311_service_requests` LIMIT 5
Here “Coyote” will be replaced with “doggy”.

g) CASE FUNCTIONS –

CASE functions are used to change the case of a particular string, and they are of two types LOWERCASE and UPPERCASE.

h) LOWERCASE –

LOWERCASE can be used to return the original String with all the alphabetic characters in the lower case for string arguments.

Syntax: –

LOWER(value)

I) UPPERCASE –

UPPERCASE can be used to return the original String with all the alphabetic characters in the upper case for string arguments.

Syntax: –

UPPER(value)

4. BigQuery Substring Function

BigQuery Substring Function helps to extract a section of the String in BigQuery. It helps make calculations and visualizations easier for the users and can be used in conjunction with other BigQuery parameters, which can help enhance the performance.

Syntax: –

SUBSTR (value, position[, length])

Conclusion

In this article, we discussed Google BigQuery and the key features that make it useful for businesses. We also discussed different BigQuery String Functions, which can be used to transform and manipulate strings in BigQuery, such as CONCAT, TRIMMING, etc., along with their syntax.

In the end, we will also discuss the BigQuery Substring function, which helps extract a section of the String in BigQuery and thus helps enhance the performance.

Object Lock The Key to Immutable Data in Modern Tech

Today, we’ll discuss something hotter than a summer’s day in the tech world – data security. It’s a big, big deal these days, I mean, seriously, everyone’s going crazy for cloud storage like it’s the latest fashion trend. But hold up, we’re talking about our precious data here, not just a new pair of sneakers. So, you better believe it’s no laughing matter!

Let me introduce you to the superhero we all need in our digital lives – “Object Lock”! This guy’s the real deal, here to save the day when keeping our data safe and sound, no matter what.

In this blog post, we’ll dive deep into why Object Lock is like the rockstar of data integrity in our modern tech landscape. So, prepare to fasten your metaphorical seatbelts because we’re about to embark on an epic journey through the fascinating world of data protection and immutability!

1. Understanding Object Lock: A Shield for Data Immunity

Ever heard of an object lock? It’s your data’s fortress, standing guard to keep your precious digital files safe and sound. Picture this: It’s the barrier that prevents anyone from accidentally or intentionally messing with your data for a set period. Imagine it as a protective force field for your digital world.

Now, why is this a game-changer? In fields where rules are like holy scriptures—think medicine, banking, and law—Object Lock is the real MVP, ensuring your data remains rock-solid and squeaky clean, following all the rules and regulations.

2. The Essence of Immutability in Data

Picture this: You’ve got some important company documents, and someone messes with them without your knowledge or permission. That could lead to a total disaster – financial losses, legal troubles, and a wrecked reputation. This is where data immutability occurs, and Object Lock becomes its trusty sidekick.

When data gets written and locked down, immutability guarantees it can’t be changed, overwritten, or deleted until a set period is over. So, even with a cyberattack or an oopsie moment, your data stays true and untouched – a real pillar of reliability.

3. The Mechanics Behind Object Lock

Now, how does Object Lock work its magic? Well, it’s all about setting time limits and legal boundaries. A retention period is like a countdown timer that makes data untouchable for a certain time. During this window, no one can fiddle with it, giving an extra layer of security against unauthorized meddling. And then there’s the legal hold, which is like a “hands-off” sign for data involved in legal stuff. It stays locked until the legal hold gets lifted.

4. Use Cases of Object Lock

Let’s dive into some real-world scenarios where Object Lock shines:

Healthcare and Patient Records

In the healthcare world, patient records are gold. If someone messes with them, it could mean misdiagnoses, bad care, or even lives at risk. Object Lock steps up here, keeping patient data rock-solid, protecting patients’ and healthcare pros’ reputations.

Understanding Object Lock A Shield for Data Immunity

Financial Compliance

So, how do banks and financial institutions handle some seriously sensitive stuff? I’m talking about your bank account details and your entire transaction history. Well, they’ve got to play by the rules, you know, stuff like Sarbanes-Oxley and Dodd-Frank. To do that, they’ve got to make sure their data is like Fort Knox – untouchable.

That’s where Object Lock comes into the picture. It’s their secret weapon for keeping all those financial records in tip-top shape. It’s like a super-lock that ensures everything stays accurate and transparent; no funny business is allowed.

Legal Sector and E-Discovery

Legal folks and law firms deal with electronic evidence in court. It has to stay unchanged to be valid. Object Lock ensures that electronic evidence can’t be messed with, making legal cases stronger and the justice system more reliable.

Long-Term Data Archiving

Companies must store data for ages because of business, legal, or regulatory stuff. Object Lock is their go-to, ensuring archived data stays the same during storage time. It’s like a trustworthy time capsule for future reference.
