Trading can be exciting, but it is also unpredictable. Many traders lose money because they start trading live without testing their strategy. This is where backtesting comes in. It allows traders to test their strategies on historical trading data before risking real money. By understanding how a strategy would have worked in different market conditions, traders can make smarter decisions and reduce risks.

Google recently introduced a columnar engine for its globally distributed database, Spanner, intending to resolve the long-standing conflict between online transaction processing (OLTP) and analytical query processing (OLAP). The new feature, currently in preview, allows Spanner (Enterprise and Enterprise Plus editions) to handle both workloads simultaneously on a single database, eliminating the need for separate data warehouses and complex ETL (Extract, Transform, Load) pipelines.

Cheering at the stadiums and buying replica jerseys shifted to new ways to consume sports. Live matches on the Sportsbet betting platform, social media, fantasy leagues, highlights, and apps are capturing the attention of today's fans.

This triggered an entirely new approach based on data about fans' behaviours, which proved to be just as valuable as the sports themselves.

Pew Research asked U.S. adults if certain behaviors in public, such as cursing or smoking, were acceptable. The above are the results for four age groups. For every behavior, the percentage of people who said it was rarely or never acceptable increased with age. Television and movies (and my own experiences) would tell you that sounds about right, but for some reason the clear trend surprised me. A quiz with the behaviors lets you get in on the action to see how crotchety you are.

Over the course of several years designing and delivering enterprise data platforms for a global pharmaceutical leader, I witnessed firsthand how data had evolved from a backend enabler to a frontline business asset. The organization was no longer just looking to report historical performance; it needed to predict outcomes, personalize patient engagement, customer engagement, brand performance and make regulatory decisions in near real time.

MySQL 9.0.0 introduces a new Vector datatype, JavaScript Stored Programs, updated library versions, and enhancements to the Event Scheduler, while deprecating old SHA-1 security.

There is a complete reset in how data is managed and flows around the enterprise. If people want to seize the AI imperative, they have to redo their data platforms in a very big way. And this is where I believe you're seeing all these data acquisitions, because this is the foundation to have a sound AI strategy.

Venn diagrams use overlapping circles to show the relationship between two or more things, facilitating comparisons across various fields.

A Common Table Expression (CTE) is a named, temporary result set defined within a single SQL statement, which helps in improving query readability and maintainability.

Both cache() and persist() store an RDD/DataFrame/Dataset in memory (or disk) to avoid recomputation. cache() is shorthand for persist(StorageLevel.MEMORY_ONLY), while persist() offers more control.
