For my article on 1.e4 c5 2.c3 Qa5, the "work" database contained ~500 games. In other cases far less. This smaller base becomes the new "Referenzdatenbank" (reference database?) so that searches for a position with this Qa5 topic only take a second. Key games are analyzed and afterwards saved in this small base. Or I throw all games into one "main" game. I am used to analyze not in CB8, but in the Fritz GUI, using Rybka4 as engine (or others). A work base is prepared in a few minutes, the analysis can take weeks or months.

Could you elaborate on this statement Stefan?

In ChessBase 8.0: Ctrl + left-click to "collect" databases, then Ctrl + F (or right-click) to open the search window for the desired search over all your 50+ million games in one go. Take a coffee pause then... 
It's simple and I was never tempted to mix the 3.8 million games of MegaBase 2008 with other databases. Better to keep databases separated: those bought on CD / others which need a regular backup.

Such hostility indicates you don't have a proper answer to provide.

First of all, there are no other avenues to ask this type of question.

2nd, I am not the one who started this thread.

3rd, before you go off the deepend on pointless character attacks... realize that A) I have devoted thousands of hours to my databases. I have to maintain numerous small ones because of chessbase's inability to handle one large one. B) Again my problem is no where near unique. Why should the amount of time I have or have not spent should dictate whether or not someone is willing to help.

4th, you professed that there was a simple way to maintain large database but now you refuse to provide an answer. So is there or isn't there a way to do it?

Finally, if you have no interest in helping its probably better to just not respond at all.

a couple of issues... none of you are actually describing to me how you made your database. What feature within SCID and Chessbase did you utilize?

It needs to be said chessbase has a hard max games it can access in one file (I believe the number is 20million but don't quote me on that). It slows down immensely if its trying to access anything over 10million (and in many cases just out right crashes) even with SSD. Chessbase also does not handle pgn very well -- which is honestly downright pathetic.

I don't believe my problem is anywhere unique (btw i'm using chessbase 11 though I have 10, 9, and 8). The numerous GMs I have talked to can't make chessbase work either properly for database functionality so they just end up purchasing databases (as some have said opening master) but in many cases they just purchase Megabase. This route only serves to highlight the errors within the current software options if this route is the *only* solution.

I should add I know someone that has an incredible database but they spend nearly 4 hours *every day* creating and maintaining that database. This kind of time commitment is also unrealistic.

So my question is still left unanswered.... how do you make a large usable database?

I apologize my response is quite slow... been very busy.

How does one access multiple databases in a single shot? This workaround could get around the need for a large database...

I have just now performed a similar task on my laptop using the full version of chessbase 9 and it took the program only 8 minutes (!) to complete it.

So I suppose it must have something to do with the light version despite it´s activation.

I quite like the functionality of CB 9 and see no reason for an update either. Most important for me it´s stable and quick.

Edit: The same task takes 2 minutes if I only use the import into the opening keys and pass on the other ones , which I hardly ever use.

[quote]I have CBlight 2009 - the activated version for 50€.[/quote]

The trouble (or one of them) is, this is no longer on sale, and you now have to spend twice that amount to acquire comparable features/possibilities. I have ChessBase 8, which doesn't allow me to import games from ChessLive.de, and I really do not want to spend a hundred quid to be able to do this. ChessBase might be making more money having withdrawn the 'activated' CBL 2009, but I fear they have made no friends ...
