we need to create "SharpDBMS Development Group" #1

Though you have it in the StepsDB issue you posted, it's worth adding csharp-sqlite (though note that that link should break in August. There's a post that they'll move to GitHub at some point). First, a quick reply to the issue you raised on StepsDB:
Okay, whoa, yes it does! It doesn't support I'm not going to pretend SqlDbSharp is great -- it looks like NetBase has done a much better job with parsing than the rats' nest I currently have, for instance, though the license (LGPL on CodeProject and GPL on GitHub) is much more restrictive. Not absolutely sure what StepsDB is doing. It doesn't seem to have a SQL parser, and mentions third parties. Is it an overlay on top of (or under) other engines? I hope SqlDbSharp gets better the more I "really" use it on other projects (indexing is probably next), but it's not like I'm doing high-level comp sci; more just practical bit pushing. So though I'm really happy to see someone bring C# native DBMSs together, I'm more about day-to-day usage (aka "mvp") than pushing forward DBMS tech. What exactly did you have in mind? Do you just want to create a mailing list or something similar? |
Ideally, i want to have all useful code consolidated into single working solution (to be able to run EF6 examples on it).

Unfortunately, the closest project to establishing a "real" rdbms with native C# was, imo, csharp-sqlite, but it's been mothballed, as I understand it. In two years, there have been only two checkins, both on the same day in 2014. Though I've used EF with SQL Server, honestly I'm unsure what would need to happen to get Entity Framework support in a dbms. EF is open source, though, so that's an answerable question. Honestly, it looks like there are two strategies, if EF support is your goal. Either wait for a project to become mature enough that it wants to add it, or fork and start fooling around yourself. I'm not sure that the different projects you've listed have similar philosophies or goals... I know EF isn't next on my list. Sorry to let this get so long, but what I'd like to see is a permissive-license (LGPL with exception, Apache, MPL, or MIT/BSD) generic, reusable parser library. I've wondered if Irony (more here) which supports SQL-89, isn't that project, but haven't taken the time to look, as my rats' nest parser is unfortunately working "well enough" for my uses now.
It might be worth polling other C# projects to see what modular pain points they have, and collect those at a project or website you create. Just coordinating problems, looking for overlap, and working on or even just keeping track of work on possible solutions might be a good first step for you, if you're interested. I'd appreciate it. HTH, let me know how I can help, and good luck. |

The locking on tables is exclusive by default, within serializable transaction isolation. Said this, I'm working to refactor the whole solution with the latest code developed for CloudB (part of the code) and create a more coherent and stable application that can be run safely as a server as well." |
@ArsenShnurkov I'm the owner of CloudB, as you can see: I'd be glad to support you if you need any help with your work (or even better, if you wish to collaborate). |
The state of art as of 2015:
== Java-originated efforts ==
1998, There was 1st pure java database = Hypersonic SQL (Thomas Mueller)
2001-10, SharpHSQL (Mark Tutt) port to C# (see http://www.codeproject.com/KB/database/sharphsql.aspx )
my nonworking EF6 provider for that - https://github.com/ArsenShnurkov/SharpHSQL/tree/master/src/SharpHsql.Linq
2001, Thomas Mueller joined PointBase Inc. where he wrote PointBase Micro, a commercial Java SQL database.
2001-03, "HSQLDB Development Group" is formed ( see http://hsqldb.org/web/hsqlDevelopment.html )
2010-06-06, HyperSQL 2.0 released, SQL-92 support completed (almost, see http://hsqldb.org/web/features200.html )
2015-06-30 - HyperSQL 2.3.3 (BSD) latest release ( see http://hsqldb.org/doc/2.0/changelist_2_0.txt )
2004-05, Hypersonic 2 (MPL/EPL) started ( see http://h2database.com/html/history.html )
2008-01, IKVM conversion of H2 to .dll (see https://groups.google.com/forum/#!topic/h2-database/QAvFqbyd4_0 )
2008-06, H2Sharp (=.Net providers over IKVM result) was created ( https://code.google.com/p/h2sharp/ )
== pure C# engines ==
There are also several independent projects:
-- UPD:
2011-03, csharp-sqlite,
C#, MIT
it is moving from google code to github, details are not published yet
(many clones exist on github now, ?? https://github.com/opless/csharp-sqlite )
from your comment (https://github.com/ruffin--/SqlDbSharp/issues/3#issuecomment-125018274 ):
2009-09-30, DeveelDB = https://github.com/deveel/deveeldb
C#, GPL v3 ( https://github.com/deveel/deveeldb/blob/master/src/deveeldb-server/LICENSE )
BSD license is mentioned on page http://www.codeproject.com/Articles/43241/DeveelDB-A-Brief-Introduction
-- :UPD
I think, we need to create "SharpDBMS Development Group" or similar, to catch up with Java rivals.
