i've just sayed that the price of this solution is not fixed. that's it. I haven't said it s not the right tools... by the way the post of Member10610008 seems to "promote" this solution hardly... even if he don't know the specifics of marc's project. "What you need is a mature, full-featured, hi-performance object database management system ("ODBMS")" .... mouais...

licence per developper : 400$ and Deployment licenses/royalty "Our runtime royalty is determined on a case by case basis. We would like you to suggest a pricing model that fits your business. It might be a share of your profits, a fixed amount per deployment or something else. We are very flexible but we do need revenue to maintain development, support and pay our staff." so not a fixed price.... we don t know how much we will pay when we'll go in production.... licence per developper is not so high (if the performance are here) and we can use it for free for trial usage for less than 3 user but doesn't know how much we will pay or how much we will need to tax our customer to install the db is unacceptable, specialy if we make a startup or little business...

i think the biggest problem for this style of project (orientdb, neo4j, mongodb etc) is the fact that client are develop and maintain by external developper (now mongodb have internal dev for each port of client and that s a very cool thing) if you look at the binary client for orientdb in .net, the last release is 2 years ago .... I think if you choose oriendb , you must do your own client.

Did you look at orientdb... it seems to be a mix between a document db and a graph db and a relational db

you got it , tx dave

... why do you change your UI... You ve done all what i hate about the 2.0 style rss article presentation... we didn t see well if an article is new or update (all are grey)...we can t distinguish and remember well the article title (maybe font or color...) you ve got too much information on the main page. why do you remove the tab control classification... in the article page, why do you remove the control tab... look at that , you ve got a left menu with 5-6 options and nothing under... when we scroll down, the article takes only half of the page... with the control tab it was net and clear... damned...
