New submission: Tomorrow's Database, Today / 明日数据库，今日呈现

by HOW2025

Yurii Rashkovskii has submitted a new session! Tomorrow's Database, Today / 明日数据库，今日呈现 Conservatism is highly valued in the database world. Whenever data is involved, the stakes are high – data inconsistency, unavailability, corruption, and loss are all devastating for business. However, conservatism leads to stagnation. Unlike hardware, software visibly lags. So, how do we augment pragmatic conservatism with the need to catch up and make business solutions that propel us into the future? 在数据库领域，保守主义备受推崇。只要涉及数据，风险就很高——数据不一致、不可用、损坏和丢失都会给业务带来毁灭性打击。然而，保守主义导致了停滞不前。与硬件不同，软件的滞后显而易见。那么，我们如何在务实的保守主义与追赶时代步伐的需求之间取得平衡，打造能够推动我们走向未来的商业解决方案呢？ Open session [https://sessionize.com/app/organizer/session/19661/953634] These notifications can be turned off on Edit event [https://sessionize.com/app/organizer/event/edit/19661#_tab-advanced] page.

Re: Request for Verification Letter of Invitation

by Cédric Villemain

Dear Grant and Fawei, I thank you both, Grant and Fawei, very much more all the efforts provided, I confess I didn't understood how challenging it can be, so thank you even more knowing how time consuming it has been. Andrea and I will be Data Bene ambassadors then! And we will relay also inputs from Yasir to IvorySQL technical team.

Re: Request for Verification Letter of Invitation

by Grant Zhou

Dear Yasir and Cedric, I regret to inform you that we were unable to obtain the verification letter despite our best efforts. After multiple attempts and exploring various approaches with the relevant office, our requests for the verification letter have been declined. Unfortunately, visa requirements for Pakistani nationals have remained strictly regulated since 2020, which has impacted our ability to secure the necessary documentation. We sincerely apologize for that and appreciate your understanding of these circumstances beyond our control.

I already booked a hotel for this night. The tour you mention sounds really interesting, but I'm afraid I'll need some time for catching up with work and relaxing a bit. We can plan to take the train in the afternoon to go to Jinan. > - As for Jinan, I'll book the same hotel as the venue, but let me > know if I should book something else. > > > *you don't need to book the hotels in Jinan, we will help to book and > just let us know the days you will stay.* Thank you! According to the information below, I'd stay for the City tour of Jinan. So my hotel needs would be for the days 26th-29th. On the 29th I'd need to take the train back to Beijing, and from there to PKX airport. My flight is around 2am on the 30th (on that night, but late) and while I'd like to plan with enough time to make it comfortably, I guess I should have time enough to participate in the city tour. > > - Is there any plan at the conference on the 28th?
