What's wrong with SQLite? IIRC, It also supports in-memory databases.

- The OP described a reasonably complex database, that requires maintenance and enforcement of relationships. This is just the kind of use case at which relational databases excel.
- Speed, while important, is not the primary criterion for a database engine. Data and relationship integrity is.
- When choosing between a mature database engine that is used in billions of devices and a relatively unknown engine, the mature product will usually win. Very few people can afford to bet their product (or their reputation) on unknown quantities.
This does not mean that I would never try unknown products. It does mean that I will use them only in non-critical (i.e. non-production) environments until I am sure that (a) they can do what they claim to do and (b) are better in some significant way than the mature product.

That are some good points, SQLite is of course on the market for quite a long time and LiteDB undoubtedly still has some bugs as it is a relatively young product.
So we will see what CodeWraith thinks of it (if he decides to use it).
Exciting times!

I will try both of them. At the moment I can't yet sayhow much of a database I'm going to need. While I will have a few tables, I doubt that many of them will contain more than 1000 rows. Enforcing referential integrity is important, because I have come to rely on it as a safeguard against sloppy application logic. And my queries? They will not be very complex, as far as I can say at this early stage. Let's just wait and see where this leads to.
Anyway, thanks for both suggestions.

I would prefer this one[^], but that would be a sinfully expensive toy[^].

I've used sql ce for a couple of personal apps...works fine, but has limitations. (no views and windows only being big ones) If it's windoze only, there's always ms access. (the older free version)

Thanks, but that does not help very much. I think that both will not work very well in a DirectX graphics context.  I have a homemade UI that needs some more development and I need something that provides the model part of the MVP pattern it is built around.

Marc wrote, in the "It's weird when" post (here) he thought his brain might need an "augment."Quote: On Wednesday, scientists reported a driver of aging that, in contrast, even the lead researcher diplomatically calls “counterintuitive”: neuronal activity. Aging, of course, affects the brain. But the brain seems to affect aging, too, they found: In creatures from worms to mice to people, high levels of neuronal firing spell a shorter life span. Lower levels — naturally, or due to drugs that dampen neurons’ activity — increase longevity.
The discovery was so surprising that it’s taken two years to be published (in Nature) because of how much additional data the outside scientists reviewing the study requested. Geneticist Bruce Yankner of Harvard Medical School, who led the research, understood their skepticism. “If you say you have a cat in your backyard, people believe you,” he said. “If you say you have a zebra, they want more evidence.”

That was just the reminder I needed to post this provocative study which, given that so many of you are roundworms, I think is relevant.

I don't know why this is so surprising given the correlation between metabolic rate and longevity.
|
|
|
|

for human beings:
1 Basal metabolic rate (BMR) declines, naturally, with age
2 BMR does not correlate with longevity: that assumption, scientifically "popular" since 1908, has been refuted by modern research
3 the topic here is neuronal activity, not metabolic rate
Your science needs topping up
cheers, Bill

Judging by the code I've had to work with, many programmers will live to be in the 100's...

Wannabe manager stumbles in my penthouse office: "What is your status?"
Me, annoyed: "Still not married. Have you come to propose?"
Idiot: "No, are you still working on your project? I want you too <generic stream="" of="" nonsense="">. And put that into your database!"
Me, even more annoyed now: "No. There is no time for that if we want to make our deadline."
Idiot blinks, reboots for a few seconds and repeats the sream of generic nonsense.
Me: "I understood you the firat time. The problem is that the database will not even take this because of the constraints, not to speak of the changes I would need to make to the application."
Idiot:"Can't we just use another database with less constraints?"
Me, slowly getting devious: "Great! Why don't you take this to the boss? That would really solve a lot of problems. And don't forget to mention that I will need one or two more months to make your changes."

"The other database is not SQL, meaning it's only consistent eventually."
That'll scare him off

I'm not sure 'idiot' knows what 'consistent' or 'eventually' means - those words are far to long...

Other DB bad. No SQL. Not consistent. No more money.
