Mix source data with different granularity into the same fact table?

I have two transaction tables "Incident (157 columns)" and "Unit (70 Colums)". For every "Incident" that happens there could be one or more records in the "Unit" table.
As part of my data mart design, I have merged both the tables into a single Fact "Incident Fact (227 Columns)" and inserted the records from both the tables with a join condition between them [incident.IN_NUM = Unit.IN_NUM].
Is this correct, is my question? or am I mixing source data with different granularity in the same fact table. Appreciate your help.
Best Regards
Bees

Bees,
Are the measures from 'Incident' , repeated for a given incident where it has more than one record in the Unit table ? If so, then the sum(indicent.measure) will give an incorrect result, no ?
What requirement is there to physically merge the tables together outside of OBIEE? With OBIEE you could have one logical 'fact' table to present to report users, which sourced from seperate Incidents and Units tables and would stop the incorrect aggregations occuring. A common modelling piece in the same way would be Order Headers and Order Lines, quite common in OBIEE to have a logical 'Orders' fact which contained both Order header measures and Order line measures, this translates to your Incidents -> Units relationship.
To do what I've mentioned, is relatively straight forward, you need a 'Dim - Incident' with two levels, Incident and Unit, mapp the unique identifiers in as the level keys and then use these levels to set the content levels correctly in your 2 logical tables sources for logical 'Fact' , ie Incidents LTS at incident level, Units LTS as units level.
Hope this helps, let us know if you get stuck.
Cheers

Store XML data as relational data into Oracle tables using Java and XMLType

I want to store xml data into an Oracle 11g table as relational storage, not as CLOB or Binary storage. Then I should also be able to query and fetch this data from table into an XML file.
Any hint on how to write java code using XMLType to achieve this?
Any help would be appreciated.

Thanks for the explanation. I still have few confusions. I will try to elaborate my requirement with a simple example...
I have the following xsd and xml files. "note" would be the table in database and "to", "from", "heading" and "body" would be the columns of note table. "Tove", "Jan", "Reminder" and "Don't forget me this weekend!" would go as data in one row of note table.
How do I create note table with the xml schema (xsd file)?
Should the note table be of XMLType or the columns?
How do I load the XML data into the columns of note table?
How do I retrieve the row of note table as XML file?
XML Schema:
<?xml version="1.0"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
targetNamespace="http://www.xxxxx.com"
xmlns="http://www.xxxxx.com"
elementFormDefault="qualified">
<xs:element name="note">
<xs:complexType>
    <xs:sequence>
      <xs:element name="to" type="xs:string"/>
      <xs:element name="from" type="xs:string"/>
      <xs:element name="heading" type="xs:string"/>
      <xs:element name="body" type="xs:string"/>
    </xs:sequence>
</xs:complexType>
</xs:element>
XML Data:
<?xml version="1.0"?>
<note>
<to>Tove</to>
<from>Jan</from>
<heading>Reminder</heading>
<body>Don't forget me this weekend!</body>

How to store xml data fragments, that will not be queried?

Hello,
Delphi Client application communicates with Java Server application via XML messages. Client sends XML message over HTTP Post method. Java Servlet gets XML message, parses it, performs requested action (select/insert/update/delete), generates resulting response and sends it back to the Client.
I use Oracle DB XE 10.2.
For example: Client sends a request to the server, to append certain Order with new Product info:
Request:
<?xml version="1.0" encoding="UTF-8" ?>
- <Request OrderID="123123123" Action="NewProduct">
- <Product TempProdID="2" ProdName="L01" VisualID="1" Amount="1" TechClass="1" TechSubject="1" TechVersion="0" TechName="TestTech" ElemOk="0">
<Modified UserID="XXX" UserGroup="XXX" GroupLevel="0" />

I use DOM parsers to parse the received requests, extract certain info and insert it into relational tables using standart SQL queries.
My question is: what is the best way to store XML data fragments, that are not required to be saved relationally? I need to save the content of node <TechProduct> from the above example to relational table's column. There will be no need to query this column, no need to use relational views. I will use it only when Client application will request to modify certain order's product. Then I will have to send back the same <TechProduct> node via XML response.
So what column type do I have to use? CLOB? XMLType? Is it better to use object types? Do I have to register XML Schema for better performance? The size of the fragment can be ~2MB.
Thanks for your help

Thank you for reply,
As you suggested, I will use XMLType storage as CLOB (without XML Schema).
As I mentioned before, I use Java Servlet, deployed on Tomcat WebServer, to receive XML messages from Client application via HTTP POST method.
I use these libs to get the XML payload and parse it into a Document:
import org.w3c.dom.*;
import org.xml.sax.InputSource;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.DocumentBuilder;
And here is the code:
public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
try {
// get the XML payload and parse it into a Document
DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder();
Document dom;
InputSource input = new InputSource(request.getInputStream());
dom = docBuilder.parse(input);
catch(Exception ex) {
System.out.println("Exception thrown in XmlService");
ex.printStackTrace();
throw new ServletException(ex);
I create a relational table, that contains XMLType column:
CREATE TABLE xwarehouses (
warehouse_id NUMBER,
warehouse_spec XMLTYPE)
XMLTYPE warehouse_spec STORE AS CLOB;
Now I want to insert all DOM Document into XMLType column. So I do like this:
import oracle.xdb.XMLType;
String SQLTEXT = "INSERT INTO XWAREHOUSES (WAREHOUSE_ID, WAREHOUSE_SPEC) VALUES (?, ?)";
XMLType xml = XMLType.createXML(con,dom);
PreparedStatement sqlStatement = con.prepareStatement(SQLTEXT);
sqlStatement.setInt(1,2);
sqlStatement.setObject(2,xml);
sqlStatement.execute();
sqlStatement.close();
dom is the Document, that I got from HTTP Request input stream.
My servlet throws an exception:
java.lang.NoClassDefFoundError: oracle/xml/parser/v2/XMLParseException
at XmlService.GetMatListServiceHandler.processRequest(GetMatListServiceHandler.java:111)
at XmlService.XmlServiceHandler.handleRequest(XmlServiceHandler.java:43)
at XmlService.XmlServiceServlet.doPost(XmlServiceServlet.java:69)
at javax.servlet.http.HttpServlet.service(HttpServlet.java:716)
at javax.servlet.http.HttpServlet.service(HttpServlet.java:809)
why does he needs oracle.xml.parser.v2.XMLParseException? I don't use Oracle parser? Does this code line throws the exception (I am not able to debug my code, because I have not configured JDeveloper to be able to use Remote Debuging):
XMLType xml = XMLType.createXML(con,dom);
Does it reparses the given dom Document or what?. When I deploy xmlparserv2.jar to Tomcat, everything is ok, application inserts XML data into XMLType column.
Is there another way to insert the whole org.w3c.dom Document or Document fragment (that is already parsed) into XMLType column. Can you provide any sample code?
The Document may contain national symbols, so they should be correctly stored and then later retrieved.
Many thanks.

Write / store xml data in Xe and retrieve stored data using pl/sql

Hi to all,
i'm searching a tutorial on:
A - how to write / store xml data in Xe and retrieve stored data using pl/sql
I don't want to use other technologies, because i use htmldb and my best practice is with pl/sql.
I was reading an ebook (quite old maybe) however it's about oracle 9 and it's talking about xmltype:
1 - I don't understand if this is a user type (clob/varchar) or it's integrated in Oracle 9 however i will read it (it's chapter 3 titled Using Oracle xmldb).
Please dont'reply here: i would be glad if someone can suggest me a good tutorial / pdf to achieve task A in Oracle XE.
Thanx

Thank you very much Carl,
However my fault is that i've not tried to create the table via sql plus.
Infact i was wrong thinking that oracle sql developer allows me to create an xmltype column via the create table tool.
however with a ddl script like the following the table was created successfully.
create table example1
keyvalue varchar2(10) primary key,
xmlcolumn xmltype
Thank you very much for your link.

Using FGA in Oracle 9i on tables that store XML data

Hello,
Our company wishes to use FGA policies to log transaction data for updates that take place in our software (Web based software using Oracle 9i Enterprise Edition (9.2.0.6.0))
This is working just great for logging transaction information on all of our tables except for those that hold XML data. It seems that the XML code is causing an error as it attempts to write in to an audit entry. I have requested information on the specific errors that are being generated, and do not have the exact messages to post yet - but I was hoping that someone out here could comment on FGA and XML data logging, if this is even possible in 9i, or if particular add-ons or updates may need to be made to the database before this can be expected to function as desired.
Thank you in advance,

Is the intent to audit tables containing XML or to audit changes to the XML? There is a huge difference.
Also, working in software as older than my car isn't helping you. How about applying a few patches or upgrading to something supported?

XML data with nested repeating nodes

First let me prelude with my skill set; "I am an XML,
JavaScript and Spry newbie". My xml data looks like this:
<report>
<header>
<column type="[string|real|int]>some
value</column>
<column type="[string|real|int]>some
value</column>
</header>
<details>
<row>
<cell type="[string|real|int]">some value</cell>
<cell type="[string|real|int]">some value</cell>
</row>
<row>
<cell type="[string|real|int]">some value</cell>
<cell type="[string|real|int]">some value</cell>
</row>
</details>
</report>
- report/header/column is completely dynamic and not known in
advance
- each report/header/column is the table column name value
- each report/details/row/cell is the table cell value
- type="[string|real|int]" is data type of the cell value
Using Spry 1.5 I have been able to successfully populate the
table column header row dynamically and repeat the appropriate
number of rows.
Spry is Cool!
I have not been able to figure out how to repeat
report/details/row/cell for each repeating row node. If I nest
spry:repeat it appears to go into an endless loop.
I will also need to equate data type to a Spry data type so
that I may sort the columns appropriately for their respective data
type.
Here is the code I have so far:
<script language="JavaScript" type="text/javascript"
src="includes/xpath.js"></script>
<script language="JavaScript" type="text/javascript"
src="includes/SpryData.js"></script>
<script language="JavaScript" type="text/javascript"
src="includes/SpryNestedXMLDataSet.js"></script>
<script type="text/javascript">
var dsReport = new
Spry.Data.XMLDataSet("data/cmbcov_raw.xml", "/iqreport");
var dsHeaders = new Spry.Data.NestedXMLDataSet(dsReport,
"header/column");
var dsRows = new Spry.Data.NestedXMLDataSet(dsReport,
"details/row");
var dsCells = new Spry.Data.NestedXMLDataSet(dsReport,
"details/row/cell");
Spry.Data.Region.debug = true;
</script>
<link href="/report/css/samples.css" rel="stylesheet"
type="text/css" media="all" />
<meta http-equiv="Content-Type" content="text/html;
charset=utf-8" />
<title>Reports</title>
</head>
<body>
<h3
spry:region="dsReport">{dsReport::@title}</h3>
<div class="liveSample" spry:region="dsReport dsHeaders
dsRows dsCells">
<table class="dataTable">
<tr>
<th
spry:repeat="dsHeaders">{dsHeaders::column}</th>
</tr>
<tbody>
<tr spry:repeat="dsRows">
<td>{dsCells::cell}</td> 
</tr>
</tbody>
</table>
</div>
</body>
</html>
Your assistance will be greatly appreciated!
Thank you in advance,
nomadcanuck

Don,
Thanks for forcing me to read the nested data set sample
again, three times the charm as they say :). I made the following
addition to get it to work.
var dsDetails = new Spry.Data.NestedXMLDataSet(dsReport,
"details");
var dsRows = new Spry.Data.NestedXMLDataSet(dsDetails,
"row");
var dsCells = new Spry.Data.NestedXMLDataSet(dsRows, "cell");
<tbody spry:repeat="dsDetails">
<tr spry:repeat="dsRows">
<td spry:repeat="dsCells">{dsCells::cell}</td>
</tr>
</tbody>
I am still stumped with respect to sorting the dynamic
header/column. Any chance of being pointed in the right direction,
either document or hint is appreciated.
Thanks again,
nomadcanuck

Note that i can have more than 1 machines (meaning that i have to loop thru the file to be able to write to the DB)
Cal u tellme what to do!
Even better- do u have a piece of code that will help me understand and implement the database writing portion?
I badly need help here.

HT1527 I have windows 8.1 and cannot access itunes store even creating a new apple id. With other users on the same computer I can access itunes store. How can I solve this?

I have windows 8.1 and cannot access itunes store even creating a new apple id. With other users on the same computer I can access itunes store. How can I solve this?

i had the same problem before using a fresh install of Windows 8.1. I have resolved this issue by running the program compatibility wizard. This I did by right-clicking on the iTunes icon in the desktop, selecting Troubleshoot compatibility, waited for it to detect compatibility issues and when presented with the following options: 1.) Try recommended settings; 2.) Troubleshoot program, I chose the latter. When asked what problems I noticed, I checked the following: "The program worked in earlier versions of Windows but won't install or run" and "The program requires additional permission"
After that, it tired to resolve the issue, and provided the necessary settings to run iTunes. Now it's running flawlessly. I have Avast anti-virus installed though.
HTH!

You choose to not copy them off to a computer as they are designed to be.
If they are no longer showing in iCloud, they are gone.

Can we write data to different sheets in the same excel output file ?

Hi,
No, it's not possible with 5.6.2. Excel based templates are supposed to be coming but I don't know when the release date will be.

I am trying to store music for two different iPods on the same computer, against two different Apple IDs. When I try and download content from the Cloud I get an error message?

I am trying to store music for two different iPods on the same Windows 8 computer, and when I try and download content from the Cloud I get an error message. Is it possible to have two different Apple IDs on the same computer?

Unfortunately you've discovered too late how important it is to maintain an up-to-date backup of your iTunes library (and all other data of value). You could, before wiping the drive, have considered making use of a commercial data recovery service that could (albeit at considerable cost) have extracted your library from the hard disk, even if virus infected.
In the absence of that option, you will need to restore the content of your library from its original sources:
Depending on your location, you may be able to re-download any iTunes Store purchases that are still available on the Store
Likewise, most digital purchases from Amazon (including auto-rip copies of purchased CDs) should be available from the Amazon Cloud and via the Amazon Music application - the same may be true of other commercial sources for digital downloads
Content imported from your CDs will have to imported again
The specific situation that you describe regarding the music imported from your friend's external HDD suggests that either the source is badly organized and/or originates from a source other than iTunes (other media players may use alternative tags for information like artist, title, album, etc. that are not wholly consistent with how iTunes handle these). Without details of the issues you're seeing it is difficult to suggest a remedy other than going through the media album-by-album, track-by-track, and correcting the inconsistencies.
In the absence of a backup or access to the original library data there is no option other than painstakingly recreating your library as described above. As you do so, you'll now realize how important creating and maintaining backups are - in my case I have at all times three separate duplicates of my library, in two different locations, where none is ever more than a week old compared to the content of my master library.

How do i share music with 2 iphones using the same apple id?

how do i share music with 2 iphones using the same apple id?

Sync them both to the same iTunes music library. You can also automatically download purchased music to both by going to Settings>iTunes & App Stores and turning Music to On under Automatic Downloads. If you music is in multiple computers, you can enable Home sharing to share your music library across multiple devices (see http://support.apple.com/kb/HT3819).
