c# - .NET, JSON, Embedded, Free Commercial-Use data management solution? What to do? -

-

i trying develop data management solution commercial product meets several criteria. criteria , reasoning follows:

  1. the solution should in c# or support c#
  2. manage data json
  3. no external schema maintenance
  4. be able cache or data in memory , persist disk
  5. not require additional installation
  6. if solution involves third-party software, license must support no-cost commercial use

requirement #1: application written in c# , prefer solution not involve integrating applications, libraries, or code in language.

requirement #2: there several json-based tools , libraries utilize, need solution data either in or converts to/from json.

requirement #3: want avoid schema maintenance comes using relational database solutions. prefer manage mismatched data-to-object mappings in code , have code update older data instead of managing schema updates separately.

requirement #4: require or data loaded memory @ times, , data persisted disk. whether data persists in memory or not should optional per data type.

requirement #5: when installing product don't want have secondary installations or have external services running other application. self-contained solution best.

requirement #6: intended use distributed commercial product. prefer avoid additional fees or licensing issues come many third-party solutions.

to date have tried several solutions. did not have many constraints , went sqlite.net , use wasn't unpleasant, overhead schema maintenance , data format more like. investigated lot of nosql solutions (such ravendb), other third-party solutions (karvonite), , simple json file storage implementations, i'm not satisfied of them.

is there custom approach or solution missing, else has used successfully? i'm hoping overlooking option(s) after, , nosql , .net experts out there have enough experience in area point me in right direction.

edit: in case original commentators confused, updated question , title better adhere so's policies.

fluent nhibernate automapping on top of sqlite meet requirements except edit #2 - "nosql, preferably data json document"

it automaps relational db schema object model...does not use json. edit might able save json data blob, however. (caveat: know nothing json)

i'm trying subclass qstyleditemdelegate remove focus rectangle in qcombobox . even though i'm calling base implementation of paint function , nothing else, result different. looks if parts of style-sheet influence bounding box of item taken consideration. class pstyleditemdelegate(qstyleditemdelegate): def __init__(self, *args, **kwds): super(pstyleditemdelegate, self).__init__(*args, **kwds) def paint(self, *args, **kwargs): qstyleditemdelegate.paint(*args, **kwargs) what have paint unmodified qstyleditemdelegate ? as suggested tried replacing pyside pyqt4 , works, appears bug. update pyside 1.1.2 1.2.1 result same. unfortunately switch breaks other parts of code, if there no other suggestions i'm going accept answer. edit bug tracked here

i using node.js script gather data stackoverflow. know responses gzipped, put code in should take care of that. script follows: var request = require('request'); var zlib = require('zlib'); function getstackoverflowresponse(url, callback){ request(url, {encoding: null}, function(err, response, body){ if(response.headers['content-encoding'] == 'gzip'){ zlib.gunzip(body, function(err, dezipped) { callback(dezipped); }); } else { callback(body); } }); } var url = "https://api.stackexchange.com/docs/questions#pagesize=2&order=desc&min=2014-01-04&max=2014-02-02&sort=activity&tagged=apigee&filter=default&site=stackoverflow&run=true"; getstackoverflowresponse(url, function(questions) { console.log(questions); }); instead of getting json output, i'm getting following response: buffer 0d 0a 0d 0a 0d 0a 0d 0a 3c 21 44 4f 43 54 59 50 45 20 48...
