MongoDB’s ability to embed arrays and subdocuments inside a document allowed for ACID-compliance, and fast writes before transactions were available. Since MongoDB 4.2, transactions are now available across documents, collections, databases and shards, how do you know if transactions are the right solution for your application?
In this session you’ll learn about the problems that transactions solve, their limitations, when transactions are not the best solution, and the optimal use of transactions in production.

Network Neutrality, which literally protects freedom of speech, has become a controversial concept in the U.S.
The Internet is an essential commodity in contemporary life. No one disagrees. However, not everyone agrees on the relevance of network neutrality.
Net neutrality was founded on the idea that the Internet is open to all, with all websites treated equally, whatever the platform used to access them.
It upholds the idea that Internet Service Providers (ISPs) like Verizon and Comcast should not transfer selected data into “fast lanes” so users can access them faster, and, on the other hand, block or discriminate against other content to slow them down, so users cannot access them easily.
The idea upheld is also to provide this service like a utility, and prevent discrimination in delivering its service; a city’s water supply is a utility service that affords the same water pressure to all, considering as immaterial, user identity or reason for consumption.
In other words, an ISP should not be allowed to make a huge global corporation’s website faster than a small business website. The inventor of the World Wide Web, Tim Berners-Lee, himself, says,
“It’s time to recognize the internet as a basic human right. It means guaranteeing affordable access for all, ensuring internet packets are delivered without commercial or political discrimination, and protecting the privacy and freedom of web users regardless of where they live.”
In fact, the United Nations Human Rights Council, in 2012, determined that connecting to the internet is a human right. The UN Resolution condemned all attempts to block free speech online, and stated in conclusion, that “the same rights that people have offline must also be protected online, in particular, freedom of expression.” The resolution was updated and unanimously re-adopted twice, in 2014 and in 2016.
This principle of being fair to all content and websites, took on enhanced significance during the global stay-at-home orders and consequently extensive remote work situations.

The Internet has blurred the line between reality and imagination. More futuristic technologies are emerging in the modern era of artificial intelligence (AI). The advanced thought of buying products online through immediate payments methods is a reality now. However, online payments security is becoming a serious issue. Online purchase of goods, solutions and services has revolutionised eCommerce, opening countless opportunities to entrepreneurs worldwide. Unfortunately, keeping the passwords, financial and other personal information safe is increasingly becoming critical. Online frauds are on a historic rise lately. According to a shocking statistics from Juniper Research in 2016, up to 70% of all types of credit card frauds are mainly the card not present (CNP) transactions. The number of online transactions in 2020 is roughly double or even triple of that in 2016. In such a case, you must protect your data during all aspects of business operation including online transactions. In order to secure data, people have to follow a 360 degrees approach to ensure that a security breach doesn’t take place internally or externally. Analytics Insight has compiled top 10 practices that keep hackers away while doing online transactions.

SQL Right join returns all records from the right table (table2), and the matched records from the left table (table1). The result is NULL from the left side when there is no match. RIGHT JOIN performs a join starting with the second (right-most) table and then any matching first (left-most) table records.
RIGHT JOIN and RIGHT OUTER JOIN are the same.
SQL RIGHT JOIN keyword returns all the records from the right table (table2), and the matched records from a left table (table1). The result is NULL from the left side when there is no match. In some databases, the RIGHT JOIN is called RIGHT OUTER JOIN. The RIGHT JOIN clause allows us to query data from the multiple tables.

Couchbase already has had support for atomic single document operations and [Optimistic and Pessimistic Locking] for a long time. Last year, we introduced fast transactional support regardless of buckets, collections, scopes, or shards. With Couchbase 7.0 you can even use the same traditional relational transaction syntax. The combination of all these features makes Couchbase the best NoSQL for transactions at scale.
