How to represent hierarchical data?

I am creating an application to be used to store strategic resources in a hierarchical manner. The program should be able to store and open, for example, word documents, web sites, pdf files etc stored in a tree fashion using directories. My question is whether I should create a single xml file representing the tree, descriptors of each node etc. (basically all the information in one spot) or create an xml file within each directory decribing what resources are available within the current level.
Thanks in advance for any assistance.

You should check out the way a HTTP Server organizes its content.It may help if you could check out the Apache Web server.

How to delete hierarchical data?

Hello,
I have a table with hierarchical data. I want to delete data based on a condition, but maybe this condition is only present in the topmost hierarchy.
In my example I have rows identified by id and a changed_by containing the id of the row that replaced (invalidated) this row. From these I want to delete data where descr in the leaf nodes is 'A'.
Oracle Database 11g Enterprise Edition Release 11.2.0.2.0 - 64bit Production
DROP TABLE test_del;
CREATE TABLE test_del (
     CONSTRAINT pk_del PRIMARY KEY (id)
    ,id         NUMBER
    ,changed_by NUMBER
     CONSTRAINT fk_del
     REFERENCES test_del (id)
    ,descr      VARCHAR2(10)
INSERT INTO test_del (id,changed_by,descr)
VALUES (3,NULL,'A');
INSERT INTO test_del (id,changed_by,descr)
VALUES (2,3,'A');
INSERT INTO test_del (ID,changed_by,descr)
VALUES (1,2,NULL);
INSERT INTO test_del (id,changed_by,descr)
VALUES (6,NULL,'A');
INSERT INTO test_del (id,changed_by,descr)
VALUES (5,6,'A');
INSERT INTO test_del (id,changed_by,descr)
VALUES (10,NULL,'B');
INSERT INTO test_del (id,changed_by,descr)
VALUES (9,10,'B');
INSERT INTO test_del (id,changed_by,descr)
VALUES (8,9,'B');
COMMIT;
SELECT *
FROM    test_del
CONNECT BY PRIOR id = changed_by
START WITH descr = 'A' AND changed_by IS NULL;
        ID CHANGED_BY DESCR
         3            A
         2          3 A
         1          2
         6            A
         5          6 A
DELETE FROM test_del WHERE descr = 'A';
ORA-02292: integrity constraint (FE.FK_DEL) violated - child record found
Of course I get ORA-02292 in this case, but how can I write a correct statement that deletes the data shown by the select?

Marcus

You need to follow the hierarchy:
DELETE FROM test_del
      WHERE ROWID IN (
          SELECT ROWID
            FROM test_del
         CONNECT BY PRIOR id = changed_by
           START WITH descr = 'A'
                  AND changed_by IS NULL);

How to model hierarchical data?

I need a way to model hierarchical data. I have tried using an object so far, and it hasn't worked. Here is the code for the class I made: http://home.iprimus.com.au/deeps/StatsGroupClass.java. As you can see, there are 4 fields: 1 to store the name of the "group", 2 integer data fields, and 1 Vector field to store all descendants. Unfortunately, this this not seem to be working as the Vector get(int index) method returns an Object. This is the error I get:
Test.java:23: cannot resolve symbol
symbol : method getGroupName ()
location: class java.lang.Object
      echo("Primary Structure with index 0: " + data.get(0).getGroupName());
                                                        ^
1 error I figure I can't use the approach I have been using because of this.
Can anyone help me out?

((YourFunkyClass)data.get(0)).getGroupName();Be aware that you're opening yourself up to the possibility of a runtime ClassCastException. You could consider using generics if you can guarantee that the data Vector will contain only instances of YouFunkyClass.

How to modify hierarchical data with JavaAPI?

Hi
we have a hierarchical structure for "Categories" of products. Its a simple Table of type "Hierarchy".
Now I need to add new entries to the Tree, or move existing entries to some different parents. But I can neither find a command like ModifyHierarchyTree nor is there a method to set the parent record on a HierNode instance.
How can I set the parent node of a hierarchy node with JavaAPI 2?
(Patch level is 5.5.42.65)
Thanks in advance!

Hi Roger,
I think you can modify the Data Groups hierarchy directly from within the Add Objects dialog, by clicking the Edit button to open the Edit Data Groups dialog and then using the context menu as in any editable tree to add siblings and children, and to delete and rename existing nodes
You can also edit the Data Groups hierarchy by choosing Objects ® Edit Data Groups from the main menu.
Whereas other trees allow non-unique node names as long as sibling nodes do not have the same name, data group names must be unique across the entire Data Groupshierarchy.
Hope it helped.

Krutarth

How to represent binary data?

I have some binary data which I want to assign to a variable. How do I do this?
To clarify my scenario:
long longConstant = 1234567890L;Is there something like
byte[] byteConstant = {1011B, 1000B, 1111B, 1101B, };Thanks in advance!

Everything in memory is binary, so that clarification didn't clarify anything. Your original post suggests you want to know if you can include integer literals in your program in binary (not octal, decimal, or hexadecimal) representation. The answer to that question is no, but it's easy to translate binary to either octal or hexadecimal by combining groups of 3 or 4 bits.
A hexadecimal literal starts with "0x":int abc = 0x22ab;and an octal literal just starts with "0" (zero, not oh):int def = 0777;

How can represent this data in AS3

I try declare a ArrayCollection like this
var arr:ArrayCollection = new ArrayCollection(
[{group:"Group One", members:["Jonny", "Tommy", "Lucy"]}, etc..]);
I can't declare that using static sentence.
So I do it like this:
var dpArr:ArrayCollection = new ArrayCollection();
for (var i:int = 1; i < 10; i++)
var obj:Object = new Object();
obj.group = "Group One";
obj.members = innerArr;
dpArr.addItem(obj);

Ops, I write wrong code sorry ~ _ ~

How to represent XYZ Poincaré Sphere

Hello, I will present a question I have about representation.
I'm getting the Stokes parameters to analyze the polarization modes, well, once I get them normalized.
What I want to know is how to represent the data (S (1,1,0,0), S (1.0, -1.0) for example ...) in a XY Cartesian plot, or even better on XYZ Poincaré sphere.
I need more information to represent these results? And how?
Thank you very much (sorry for my English)
Hola, a continuación voy a exponer una duda que tengo sobre representación.
Estoy obteniendo los parametros de Stoke para analizar los modos de polarización, pues bien una vez los obtengo los normalizo.
Lo que me gustaría saber es como representar los datos ( S(1,1,0,0) , S(1,0,-1,0) por ejemplo...), de forma cartesiana XY o mejor aún los datos en XYZ la esfera Poincaré.
¿Necesito más datos?
Un saludo y muchas gracias.

No one can help me, please?

How to load master data and hierarchies from R/3 systems

HI all,
how to load master data and hierarchies from R/3 systems.
Please explain the steps.
Thanks,
cheta.

HI,
Its normally done following: Transferring the master datasources in RSA5 to RSA6 and then replicating the DS into BW and assignment of DS to Infosource and cretaion of Infopackage and load it into the master tables.
Generally, the control parameters for data transfer from a source system are maintained in extractor
customizing. In extractor customizing, you can access the corresponding source system in the source
system tree of the SAP BW Administrator Workbench by using the context menu.
To display or change the settings for data transfer at source system level, choose Business
Information Warehouse → General Settings → Maintaining Control Parameters for Data Transfer.
Note: The values for the data transfer are not hard limitations. It depends on the DataSource if these
limits can be followed.
In the SAP BW Scheduler, you can determine the control parameters for data transfer for individual
DataSources. You can determine the size of the data packet, the number of parallel processes for
data transfer and the frequency with which the status IDocs are sent, for every possible update
method for a DataSource.
To do so, choose Scheduler → DataSource → Default Settings for Data transfer.
In this way you can, for example, update transaction data in larger data packets in the PSA. If you
want to update master data in dialog mode, smaller packets ensure faster processing.
Hope this info helps.
Thanks,Ramoji.

How to extract Hierarchical Master data into flatfile

Hello Experts,
I have a requirement to extract Master data (Texts, Attr, Hierarchies) of all Info Objects pertaining to a given Infocube ( say BoxA)
I am aware that I can manually dump the data / use infospoke to get data into flatfile without hassle in case of texts/attributes.
(1)But I doubt it for hierchical data. In case of hierarchical data I have to create an ABAP code to extract master data.
Below is the link I got when I am searching SDN.
http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/0403a990-0201-0010-38b3-e1fc442848cb?quicklink=index&overridelayout=true
But I didnt understand it the mechanism behind the extraction.
Can anyone please give me a detailed explanation on how to do it or some other reference documents.
Note: I am going to use that master data and import that again into different box ( say BoxB) and there is no connection between two systems (BoxA and BoxB).
Thanks.

How to represent date infinity

Hi all,
I have a persistent class with fields representing a date interval (startDate and endDate). In cases where endDate is not defined (endless interval), the field could be set to null but this would be inconsistent with sorting since null is smaller than any other date. An alternative could be to define a constant DATE_INFINITY set to December 31 9999 but I'm not sure if this is a good idea.
Any comments or alternatives ?
JCG

How about this:
public class DateWithForever implements Comparable {
// "Date With Forever" -- sounds like a cheap romance novel
private Date date;
private boolean forever_future = false;
private boolean forever_past = false;
public createDateWithForever(Date date) {
    return new DateWithForever(date);
public createDateWithForever(String forever) {
    if ("FUTURE".equals(forever))
      return new DateWithForever(true);
    if ("PAST".equals(forever))
      return new DateWithForever(false);
    return null;
private DateWithForever(Date date) {
    this.date = date;
private DateWithForever(boolean future) {
    if (future)
      this.forever_future = true;
    else
      this.forever_past = true;
public int compareTo(Object o) {
    // compare the forever boolean flags, if both false
    // fall back to comparing the dates
}

Hierarchical data structure

I am trying to represent the following data structure in hierarchical format ---- but I am not going to use any swing components, so jtree and such are out, and xml is probably out. I was hoping some form of collection would work but I can't seem to get it!
Example Scenario
Football League --- Football Team -- Player Name
West
------------------------------Chiefs
-------------------------------------------------------------xyz
-------------------------------------------------------------abc
-------------------------------------------------------------mno
------------------------------Broncos
------------------------------------------------------------asq
------------------------------------------------------------daff
This hierarchical structure has a couple of layers, so I don't know how I can feasibly do it. I have tried to look at making hashmaps on top of each other so that as I iterate thru the data, I can check for the existence of a key, and if it exists, get the key and add to it.
Does anyone know a good way to do this? Code samples would be appreciated!!!
Thank you!

Hi Jason,
I guess you wouldn't want to use Swing components or JTree unless your app has some GUI and even then you would want to look for some other structure than say JTree to represent your data.
You have got plenty options one is that of using nested HashMaps. You could just as well use nested Lists or Arrays or custom objects that represent your data structure.
I don't know why you should exclude XML. There is the question anyway how you get your data in your application. Is a database the source or a text file? Why not use XML since your data seems to have a tree structure anyway and XML seems to fit the bill.
An issue to consider in that case is the amount of data. Large XML files have performance problems associated with them.
In terms of a nice design I would probably do something like this (assuming the structure of your data is fixed):
public class Leagues {
    private List leagues = new ArrayList();
    public FootballLeague getLeagueByIndex(int index) {
        return (FootballLeague)leagues.get(index);
    public FootballLeague getLeagueByName(String name) {
        // code that runs through the league list picking out the league with the given name
    public void addLeague(FootballLeague l) {
        leagues.add( l );
}Next you define a class called FootballLeague:
public class FootballLeague {
    private List teams = new ArrayList();
    private String leagueName;
    public FootballTeam getTeamByIndex(int index) {
        return (FootballTeam)teams.get( index );
    public FootballTeam getTeamByName(String name) {
        // code that runs through the team list picking out the team with the given name
    public void addTeam(FootballTeam t) {
        teams.add( t );
    public void setTeamName(String newName) {
        this.name = newName;
    public String getTeamName() {
        return this.name;
}Obviously you will continue defining classes for Players next following that pattern. I usually apply that kind of structure for complex hierarchical data. Nested lists would be just as fine, but dealing with nested lists rather than a simple API for you data structures can be a pain (especially if you have many levels in your hierarchy);
Hope that helps.

How to change a date in one format to the other?

Hi,
Say I have a String representing a date in the following format:
dd/MM/yyyy e.g. 12/03/2002
How can I convert this String to a String representing a date the following format:
ddMMyyyy e.g. 12032002
Without using the String class.
Thanks

Let's write some code here:
String f1="dd/MM/yyyy";
String f2="ddMMyyyy";
String d1="12/03/2002";
String d2=null;
You want d2 of format f2, given d1 with format f1 =>
SimpleDateFormat formatter1 = new SimpleDateFormat (f1);
SimpleDateFormat formatter2 = new SimpleDateFormat (f2);
ParsePosition pos = new ParsePosition(0);
java.util.Date dateTemp = formatter1.parse(d1, pos);
d2 = formatter2.format(dateTemp);
That should work.
