What is NodeXL

NodeXL resolve our problem to creating Many to Many Relationship in according to data. 

Last month our team got requirement from IT Director: How we can create many-to-many relationship graph based on data, automatically ? We search and tested many tools some online and some desktop installed but  no one worked fi9 and complete as per requirement. Few doesn't responded and few suggested to use paper and pen . But Our Team Lead resolve this requirement through a simple tool that was NodeXL.





NodeXL is a free, open-source template for Microsoft® Excel® 2007, 2010 and 2013 that makes it easy to explore network graphs.  With NodeXL, you can enter a network edge list in a worksheet, click a button and see your graph, all in the familiar environment of the Excel window.

I have tested NodeXL to create show many-to-many relationship graph based on Twitter trends data.. plz follow URL..

NodeXL Features Support
  1. Flexible Import and Export   Import and export graphs in GraphML, Pajek, UCINet, and matrix formats.
  2. Direct Connections to Social Networks  Import social networks directly from Twitter, YouTube, Flickr and email, or use one of several available plug-ins to get networks from Facebook, Exchange, Wikis and WWW hyperlinks.
  3. Zoom and Scale  Zoom into areas of interest, and scale the graph's vertices to reduce clutter.
  4. Flexible Layout  Use one of several "force-directed" algorithms to lay out the graph, or drag vertices around with the mouse. Have NodeXL move all of the graph's smaller connected components to the bottom of the graph to focus on what's important.
  5. Easily Adjusted Appearance Set the colour, shape, size, label, and opacity of individual vertices by filling in worksheet cells, or let NodeXL do it for you based on vertex attributes such as degree, betweenness centrality or PageRank.
  6. Dynamic Filtering  Instantly hide vertices and edges using a set of sliders—hide all vertices with degree less than five, for example.
  7. Powerful Vertex Grouping Group the graph's vertices by common attributes, or have NodeXL analyse their connectedness and automatically group them into clusters. Make groups distinguishable using shapes and colour, collapse them with a few clicks, or put each group in its own box within the graph. "Bundle" intergroup edges to make them more manageable.
  8. Graph Metric Calculations Easily calculate degree, betweenness centrality, closeness centrality, eigenvector centrality, PageRank, clustering coefficient, graph density and more.
  9. Task Automation Perform a set of repeated tasks with a single click.

mongoDB error : aborting after fassert() failure

What to do when facing errors on mongoDB “aborting after fassert() failure”

I like errors, in mongoDB this is the first error I faced and luckily many times. This error i faced during restoring name-space on local and restarting db system. I am still searching the exact root cause of this issue but i am able to resolve the current problem through below steps.

Remove all relevant namespace files from data-file route path..Now repair mongo instance using mongod process.mongod --repair ////////// execute command from bin folder path Then start server using mongd process, if started server successfully then ..mongod  ////////// execute command from bin folder path Restore last backups as normal process.Now check database by connecting mongo shell. Thanks for reading, 
Please comment your experience if you faced and also share knowledge if you have better steps to resolve...

SQL71562: external references are not supported when creating a package from this platform

Last week I got this error from one of developer who was trying to deploy his project from Testing server to SQL Azure QA server. He was using “Deploy Database to SQL Azure” option from SSMS Tool-Task option.

After connecting to SQL Azure portal when operation started to deployment below errors occurs.

Validation of the schema model for data package failed. Error SQL71562: Error validating element xx.xxx.xx:function .dbo.xxx has an unresolved refrence to object xx.dbo.xxxx external refrences are not supported when creating a package from this platform.



Reason: The reason of the this error was; some functions of project was dependent on master database and only single database was being deploy to SQL Azure. DACFx must block Export when object definitions (views, procedures, etc.) contain external references, as Azure SQL Database does not allow cross-database external references So, this error was coming.

Solution : I suggested him to create those function to locally on local database what…
