hierarchy

I am working with d3.js to visualise families of animals (organisms) (up to 4000 at a time) as a tree graph, though the data source could just as well be a directory listing, or list of namespaced objects. my data looks like: json = { organisms:[ {name: 'Hemiptera.Miridae.Kanakamiris'}, {name: 'Hemiptera.Miridae.Neophloeobia.incisa'}, {name: 'Lepidoptera.Nymphalidae.Ephinephile.rawnsleyi'}, ... etc ... ] } my question is: I am trying to find the best way to convert the above data to the hierarchical parent / children data structure as is used by a number of the d3 visualisations such as

What in everyone's opinion is the best representation for a time-bound hierarchy in SQL? What I mean by this is: - On any given date you have a normal tree hierarchy - This hierarchy can change from day to date - Each child still only has one parent on any given date Day 1... Business | |-Joe | |-Happy | |-Sneezy | |-Doc(*) | |-Moe |-Bashfull |-Sleepy Day 2... Business | |-Joe | |-Happy | |-Sneezy | |-Moe |-Doc(*) |-Bashfull |-Sleepy At any time, a child can join the hierarchy for the first time, or leave the hierarchy completely. (For example, new employees, and retired employees.) The main

I've got a question on Maven naming conventions (groupId, artifactId and directory names) in a multiple module project with a hierarchical directory structrure. Research Before asking, I went through other the web on this topic and what I cleared out for myself: Possible duplication for my question, but it does not cover multiple-hierarchy levels. Project directory name should match artificatId . Guide to Naming Conventions provide examples: groupId will identify your project uniquely across all projects, so we need to enforce a naming schema. It has to follow the package name rules (eg. org

I'm reading the Javascript Guide from Mozilla And when they contrasted JS to Java , It got me thinking, Java code is easily split up with each class in his own file. after futher search , I understand that the same can be accomplished in JS with namespacing and module pattern - I messed around with it but got very confused ( especially with calling a constructor declared in File1.js into File2.js ) so here is the hierarchy: But i just can't figure out how to properly make it works how do i simply go from //employe.js function Employee () { this.name = ""; this.dept = "general"; } function

i have a specific Question. My Stored Procedure don't work correctly.. I will show you the Procedure, the database and the parameter: ALTER PROCEDURE [dbo].[ManufacturerParentToChild] @ServiceProviderId int, @CarmakerId int AS BEGIN SET NOCOUNT ON; DECLARE @childSPPId int, @isDeleted bit DECLARE ServiceProviderChildren_Cursor CURSOR FOR SELECT ServiceProviderId, isDeleted FROM ServiceProvider WHERE ParentServiceProviderId = @ServiceProviderId; OPEN ServiceProviderChildren_Cursor; FETCH NEXT FROM ServiceProviderChildren_Cursor INTO @childSPPId, @isDeleted; WHILE @@FETCH_STATUS = 0 BEGIN IF

for some time now I have been trying to solve the following problem and I'm starting to run out of ideas: I have generated a set of C# classes from an xsd schema using the xsd.exe tool and deserializing xml files works fine. The problem is that apart from the convenience and safety of using the auto generated classes, I also need information about the xml hierarchy, ie I need to establish parent-child relationships between the objects created during deserialization. Note that I want to avoid keeping a separate xml hierarchy structure (like a DOM tree), but rather make the generated objects
