TOKYO: Lead Like a GIRL (for men and women)...seminar with Dalia Feldheim
# Lead Like a GIRL (for men and women)...seminar with former P&G CMO, Dalia Feldheim
This Thursday, April 9th, 5:30-7pm at Deloitte Consulting in the Nijubashi Bldg in Marunouchi, learn to convert soft skills like purpose, mental perseverance, people and positivity into your competitive edge with the "Lead Like a GIRL" seminar, hosted by TED speaker, [Dalia Feldheim](https://www.linkedin.com/in/dalia-feldheim-bb9309/).
**Date**: Thursday, April 9th
**Time**: 5:30-7pm JST
**Venue**: Deloitte Tohmatsu, Marunouchi Nijubashi Building, 3-2-3 Marunouchi, Chiyoda-ku, Tokyo, 100-8360 16F

In an increasingly uncertain landscape, traditional leadership models rooted in control, strategy, and quarterly targets are less effective. Today’s most resilient companies are tapping into a different kind of leadership, grounded in psychological safety, emotional courage, and human connection. The "Lead Like a GIRL" seminar provides fundamental tools to harness and energize that volatility. Sixty minutes can help you turn emotional intelligence into a strategic weapon that aligns people, vision and culture.
[Dalia Feldheim](https://www.linkedin.com/in/dalia-feldheim-bb9309/) is a former CMO at Procter & Gamble and Electrolux, INSEAD-trained organizational psychologist, author of Lead Like a Girl, Adjunct Professor at Singapore Management University and a global keynote speaker (including a TEDx). Over two decades, she helped more than 10,000 C-suite and senior executives acquire the skills to lead with heart. Through powerful storytelling, scientific research and real-world examples, Dalia empowers leaders and organizations to transform fear into flow, and performance pressure into people-powered growth.
Join a select group of business executives at the "Think Like a GIRL" seminar, led by Europe-based Dalia Feldheim, Thursday, April 9th, 5:30pm at Deloitte Consulting, Marunouchi Nijubashi Building, 3-2-3 Marunouchi, Chiyoda-ku, Tokyo, 100-8360 16F

CBusData: The Fellowship of the Star Schema: Transforming OLTP Data for Power BI
The Fellowship of the Star Schema: Transforming OLTP Data for Power BI
One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again.
We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all.
Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.
Disc Tues / Choose Your Movie: THE CHRISTOPHERS vs NORMAL at the Gateway!
Join us as we get together for a Discount Tuesday / Choose Your Movie event to see your choice of two great new films! Option 1 (and the one I'll be seeing) is the top-reviewed comedy-drama, THE CHRISTOPHERS! The film is set in the art world and follows the estranged children of a former artist who hire a forger. It is directed by Steven Soderberg, stars Ian McKellen and Michaela Coel and has been earning rave reviews on the indie circuit. Option 2 is the latest action-thriller starring Bob Odenkirk, NORMAL! The film follows a temporary small-town sheriff who uncovers dark mysteries after a local bank robbery. Here are descriptions, trailers and our plan for this event:
THE CHRISTOPHERS: The children of a once famous artist hire a forger to complete some unfinished, long ago abandoned canvases so they'll have a better inheritance when he dies. It is directed by Steven Soderbergh and stars Ian McKellen, Michaela Coel, Jessica Gunning and James Corden. BUZZ & ACCLAIM: The film is earning an excellent 97% positive rating on Rotten Tomatoes where critics call it a “dynamic, emotional and surprising journey” and a “compelling chamber piece that works like intellectual comfort food.” Others call the film, an “incredibly funny, comedy drama with plot reversals that make it feel like it’s on the verge of a thriller!” TRAILER: https://www.youtube.com/watch?v=H79-EqzmdwY&t=20s
NORMAL: This action-crime-thriller follows a man who comes to the sleepy town of Normal, Minnesota to serve as the temporary sheriff. But a bank robbery leads him to a criminal underground reaches throughout the entire town. The film is directed by Ben Wheatley and stars Bob Odenkirk, Henry Winkler and Lena Headey. The film comes from the same team that brought us Nobody and the John Wick series, so expect an over-the-top, action-filled thrill ride! TRAILER: https://www.youtube.com/watch?v=Rmm-lM33Qw0&t=19s
PLAN: We’ll plan for a 7pm-ish showing of both films and will meet in the lobby area about 30 minutes before showtime. Once showtimes are announced, advance ticket purchase is advised (GFC website preferred)! Please list your movie of choice and seat number in the Comments section of this event. Showtimes and complete details will be confirmed/announced as the date gets closer.
PARKING: Close, convenient parking is available in the nearby garage (located between 9th and 11th, just off High St). Bring your ticket with you and have it validated at the theater and for $2, you’re covered for the night!
Look forward to seeing you there, Dan
