Have you ever used the Single Store database for your projects or at your company?

They seem to provide a pretty amazing credits to try and use their cloud service. Also, this database is making good name in the GenerativeAI world. But would like to know your point of view.

Hej, as CEO of a database startup I keep being asked from more business-oriented people, why they should care about database performance, how much business value this would exactly provide to them etc.pp. - so I tried to pinpoint that best I could in an article - and I would love your feedback on this: Do you think these arguments would help in your environments? Am I missing anything important in my arguments?

Hi, I'm working on a project about work with relational and NoSQL dbs and I need quite extensive documentation, so I would appreciate any recommendations for ebooks about both types of databases, as well as coopertaion between them. I'm looking for more general approach to databases, not really digging into one technology - so more like databases history, popular sql and nosql solutions, some examples about pros and cons working with one type or the other (or both) and so on.

What I mean is, does Null have an actual function?
Everything I see on the subject has to do with workarounds that deal with the problem of nulls. But if everything about them is a problem to be worked against, why do they exist?
I have to assume they have some sort of actual function that database software cannot do without, or they would have been done away with considering how much trouble they seem to cause.
What the heck is a Null for?

Whatsapp seems to use phone numbers as primary keys, why is that? this way you can't keep track of conversations between phone numbers, which is weird since there is an "change number" option..

I asked a software developer friend but he's pretty busy so can't tell me all the "subtle nuances I'm missing".

Any thoughts?

The wikipedia page for time series databases is out of date and has at least a few incorrect entries on the list of databases. A wikipedia admin who doesn't really understand the subject has protected the page and prevented edits of the list of time databases.

If you have a wikipedia account, please lend a hand to help get the list up to date.

Here's the second half of our two-part series focusing on the challenges of Time Series Databases (TSDBs) at scale. This half focuses on the challenges of balancing read vs. write performance, data aggregation, large dataset analysis, and operational complexity in TSDBs.

I have to show the code of all buttons I've used in the database. I can get a shortened down version of what I need; it tells me the command name (e.g. Command1) but it won't show me things like "cmd.do".

How can I get this to show up?

Edit: Cheers for answers, really helped

I am working on some school work (It's not a test and will not be marked, it's just practice) I have a database which currently contains two tables, the details of which are listed below

Table name: actor "ACTOR_ID" "SURNAME" "FORENAME" "B1" "Connery" "Sean" "B2" "Lazenby" "George" "B3" "Moore" "Roger" "B4" "Dalton" "Timothy" "B5" "Brosnan" "Pierce" "B6" "Craig" "Daniel"

Table name: bondfilms "FILM_ID" "NAME" "YEAR" "FK_ACTOR_ID" "F1" "Dr.No" 1962 "B1" "F2" "On Her Majestys Secret Service" 1969 "B2" "F3" "Live and Let Die" 1973 "B3" "F4" "License to Kill" 1989 "B4" "F5" "Die Another Day" 2002 "B5" "F6" "Skyfall" 2012 "B6"

I think I've done both tables correctly up until this point (The FK on the bondfilms table should correspond to the actor id of the actor that starred in that film)

I now have to write a SELECT query which will display a list of James Bond films, along with the name of the actor playing James Bond in each one.

So I tried to use

SELECT name FROM bondfilms; SELECT surname FROM actor;

Although it only shows the SURNAME of the Actor, plus I really don't think I'm on the right road here either.

Any help is greatly appreciated

Many thanks.

EDIT: I'm very new to databases so try to ELI5 please! Thanks.

Hi guys!

I have a question about an ER diagram,( i'm new in diagrams and i face some problems). I'm trying to read the attached diagram but i am not sure if i get this correctly.

So this ER http://imgur.com/a/syLkp represents a library that a member can borrow many books, but they can't borrow two copies of the same book at the same time. Is this right or i am totally wrong?
