Data modeling dilemma for EAV oriented problems in Data Modeler
Hello,
Dealing with EAV( entity attribute value model ) oriented structure of data.
So this look like this:
Entity( Entity_Id number , Entity_Name varchar2, Entity_Desc varchar2 )
Entity that list attributes and some meta data on characteristics of attributes:
Type_Of_Attribute( Attr_Id varchar2, Type_Of_Value TOV_Domain, Unit_Of_Value varchar2 , Min_Value variant_type , Max_Value variant_Type )
Then we have actual data. Entity is described with set of attributes and their values. So aditionally to attributes on row form in Entity there are aditional attrbutes in columnar form.
Because of sparsity...
However there in columnar form the challenge or issue is type of values so domains of attributes.
For example:
weight_of_ person is number between min_number and max_number.
But another parameter for example mood_of_person is string from the domain which consists of set of strings/descpriptions.
Another possibility could be reference to some table of values ( key value ) that could be modelled as one:many relationship if put in entity Entity on row form of attributes.
But since this is attribute relate only to few intances or it is very dispersed....and for preserving table form..it was put in columnar form ..
Attribute_Of_Entity( Entity_Id, Attr_Id, value,
-- when not normalized, could be add also unit like kg or lbs or inch or piece ).
My question is on good/succesfull practice of modelling for VALUE in attribute_of_entity?
Somewhere read that some databases have feature of so-called variant type.
Guess the objective is to modell in such a way that implementation of this model is as easy as possbile in
issues like:
a) validating column oriented form during entering or updating values
b) consolidating queries when reporting
c) agregating data when grouping when grouping data and preventing non-comparable data.
So to implement value as structure/complex_type with methods or there is any other feature supporting variabilty of the data along same column in the table. So logical design that would not cause too much complexity in the relational design and table implementation and procedures are handled as much as possible on the database level?
Thank you in advance for comments, experiences, suggestions,

Issue with xsd Data type mapping for collection of user defined data type
Hi,
I am facing a issue with wsdl for xsd mapping for collection of user defined data type.
Here is the code snippet.
sample.java
@WebMethod
public QueryPageOutput AccountQue(QueryPageInput qpInput)
public class QueryPageInput implements Serializable, Cloneable
protected Account_IO fMessage = null;
public class QueryPageOutput implements Serializable, Cloneable
protected Account_IO fMessage = null;
public class Account_IO implements Serializable, Cloneable {
protected ArrayList <AccountIC> fintObjInst = null;
public ArrayList<AccountIC>getfintObjInst()
return (ArrayList<AccountIC>)fintObjInst.clone();
public void setfintObjInst(AccountIC val)
fintObjInst = new ArrayList<AccountIC>();
fintObjInst.add(val);
Public class AccountIC
protected String Name;
protected String Desc;
public String getName()
return Name;
public void setName(String name)
Name = name;

In the above wsdl the collection of fintObjInst if of type xs:anytype. From the wsdl, I do not see the xsd mapping for AccountIC which includes Name and Desc. Due to which, when invoking the web service from a different client like c#(by creating proxy business service), I am unable to set the parameters for AccountIC. I am using JAX-WS stack and WLS 10.3. I have already looked at blog http://weblogs.java.net/blog/kohlert/archive/2006/10/jaxws_and_type.html but unable to solve this issue. However, at run time using a tool like SoapUI, when this wsdl is imported, I am able to see all the params related to AccountIC class.
Can some one help me with this.
Thanks,
Sudha.Did you try adding the the XmlSeeAlso annotation to the webservice
@XmlSeeAlso({<package.name>.AccountIC.class})
This will add the schema for the data type (AccountIC) to the WSDL.
Hope this helps.

Best data provisioning tool for very large amount of data updated real time?
about a few hundred million entries of data a day and it must be replicated to sap hana in real time, what would be the best option?
Hi Wayne,
If you are looking for real time replication, then SLT is the best option. What is the source system for this replication?

Data Writing Speed for Excel Sheet while taking data from PCI DAQ card
Dear All,
I am taking the data form the card EX-92026 pci card and writing those datas into the Excel sheet, now i want the data at the speed of max of 10 miliseconds but while writing the data into excel sheet, it shows the diff of 15 ms betn 2 readings, and the card specs says it takes the time of 500 microsecs to give the data, so is there any effect of timing, while writing data into excel sheet? is labview take more time, i am using the Open file, write file and close file method and write to spreadsheet file method, but none of them is giving me the effective timing that i wamt, so can u tell me how can i reduce it??????
Thanks,
NishantHi Nishant:
I think I don't understand you very well. If you are using OpenFile, CloseFile and WriteToSpreadsheet VIs, you are not dealing with excel files, but text files.
Writing to file is costly in time. You can:
Open the file just once and
during de process use just file writing VIs as 'write to spreadsheet'... or a more simple one 'write file'
Close the file once at the end.
If you need the process to be faster, you can save all the data at 10ms rate in an array and write to file at the end.
Or write to file every second what you got the last second.
Hope it helps

Problem converting data in XML file to internal table data
Hi all,
I have a requirement. I need to convert an XML file to internal table data and based on that data do Goods Receipt in SAP.
With the help of this blog /people/r.eijpe/blog/2005/11/10/xml-dom-processing-in-abap-part-i--convert-an-abap-table-into-xml-file-using-sap-dom-approach
I am able to convert the XML file to data in SAP. But this blog will display the output on screen as ELELEMNT = nodename VALUE= value of that node.
But I donu2019t want in that way, I want to store all the data in XML file in an internal table so that I can make use of those values and do Goods Recipt in SAP.
Can some one suggest how should I read the data in an internal table.
Here is my code..what changes should I make?

Current date of birth for my column is null getting error....
Hi All..
i am calucating the current date of birth for my column which is date field and accept nulls (cust_dob) in my table.
select cust_dob,Add_Months(
to_date(cust_dob, 'dd/mm/yyyy'),
Months_Between(
trunc(sysdate, 'year'),
trunc(to_date(cust_dob, 'dd/mm/yyyy'), 'yyyy')
) as current_dob from m_customer_hdr
when i execute my query in toad. it is showing the result. but when i scroll down to see data it thow error as
ORA-01858: a non-numeric character was found where a numeric was expected...
Thanks in advance..
Abdul rafiWhat datatype is cust_dob datatype. Somehow I have a feeling it is DATE. If so, expression:
to_date(cust_dob, 'dd/mm/yyyy')Implicitly converts cust_dob to a string using session nls_date_format and then converts it back to date using 'dd/mm/yyyy' format. Now if NULL dob are fetched first, you might get something like:
SQL> ALTER SESSION SET NLS_DATE_FORMAT='DD-MON-RR';
Session altered.
SQL> SET SERVEROUTPUT ON
SQL> BEGIN
2 FOR v_rec IN (SELECT TO_DATE(cust_dob,'mm/dd/yyyy') cust_dob
3 FROM (
4 SELECT TO_DATE(NULL) cust_dob FROM DUAL UNION ALL
5 SELECT TO_DATE(NULL) cust_dob FROM DUAL UNION ALL
6 SELECT TO_DATE(NULL) cust_dob FROM DUAL UNION ALL
7 SELECT sysdate cust_dob FROM DUAL
8 )
9 ) LOOP
10 DBMS_OUTPUT.PUT_LINE('DOB = "' || v_rec.cust_dob || '"');
11 END LOOP;
12 END;
13 /
DOB = ""
DOB = ""
DOB = ""
BEGIN
ERROR at line 1:
ORA-01858: a non-numeric character was found where a numeric was expected
ORA-06512: at line 2So if column CUST_DOB is DATE, use:
select cust_dob,Add_Months(
cust_dob,
Months_Between(
trunc(sysdate, 'year'),
trunc(cust_dob, 'yyyy')
) as current_dob from m_customer_hdrSY. -
Can a master data will have loading from more than one data source
Dear gurus,
I have a master data object which has every day loading from one particular data source. Now I got a requirement to load data from another data source. If we load data from more than one data source , will there be any problem with data? Will it accept loading from more than one data source.?
Regards
RsHi Ram,
We can load the data to target morethan one datasource.Thats advantage in BI compare to BW. It will accept loading from more than one datasource.but you have to take care about characteristic and attributes are the same in both datasources like that.

Hello. On my MacBook Air late 2013 model I am having a problem with Microsoft office word for Mac where the window for the document becomes all gray and I can not see anything that I have typed or any menus for it and also windows will sometimes dissapear and I am having truble getting them back. If anyone has anyideas of what is going on or could even help me thank you.
Glad that helped.
As time goes by (months or years), keep your eyes on how long Microsoft continues to support Office 2011 for Mac. Eventually you should consider Office 365 or Apple's Pages, Numbers, and Keynote. -

I called up data provider, they says its the problem with new software update. There is no option add APN. Now when i switch to safari its showing you are not subscribed for cellular data. But I am able to use data on other phone.
Will you please help me in this regard?
Another issue, since i bought my new iphone there is dust inside back main camera.
Your advises are highly appreciated.Hey Shaiju isac,
I'd take a look at the following article, it'll guide you though steps to you troubleshoot cellular data issues on your iPhone:

How to create a data filter for BAPI used in a Distribution Model ?
I am trying to create IDOC's for a QM inspection plan via message type QPMK in ECC 6.0. When creating the new message type in the Distribution Model, it forced me to use a BAPI (MasterInspectionChar) rather that just the message as I have done in the past. In order to ensure that only IDOC's related to a specific plant and material type get sent out, I was trying to create a filter.
I am able to get into a 'Change Filter' dialog by double clicking 'No data filter set' under the node 'MasterInspectionChar.SaveReplica'. However, an attempt to highlight anything on this dialog and clicking button 'Create filter group' results in msg. 'Select node: Content-dependent parameter filtering'.
Online help led me in a different direction, one thread led me to believe I needed to create a table entry for the filter in table TBD16 via BD81 for later attachment to the BAPI in the Distribution Model. Before this, I created two Z* ALE Object Type records for plant and material type in table TBD11 via BD95 for what I thought would provide a lookup back in BD81 for creation of a new filter record, but these objects are not found. Per the help, I am also unclear as to whether I would need to set up Receiver determination or Parameter filtering, nor where to make this step in the configuration happen?
Can anyone point me back in the correct direction to get a data filter set up for this BAPI within the Distribution Model ?
Thanks - MikeJust to clarify, what I am having trouble with is finding where exactly to plug in the name of the plant to be filtered? If using a message type such as MATMAS in a distribution model, it is very straight forward to navigate down from the 'Data filter active', and assign a value to whatever field you wish to filter via the 'List of Values'. But in this example, message type QPMK required use of the BAPI MasterInspectionChar, and therefore the different method in creating the filter.
I cannot find similar functionality when navigating the BAPI related row, for MasterInspectionChar. The 'Change Filter' dialog popup displays a row for 'Container' and then 3 more rows containing 'BAPI structure...'. Clicking the 'Attribute' checkbox on any of these rows sets 'Data filter active' as a node under the BAPI. Double clicking the 'Data filter active' brings me back into the same dialog, and selecting any row with an attempt at this point to create a filter results in the 'Select node: content-dependent parameter filtering' warning. Is this warning occuring because of missing configuration?
Thanks - Mike -
Problem in Data transfer from view to Model
Hi
I am displaying MARC data in BSP by taking Matnr as input on view.I am fetching the data in MODEL.
But, when I enter the value for MATNR in view , it is not getting transferd to MODEL. So, data is not coming as MATNR value is empty in model.
But, I hav done the DAta binding and I hav set the attributes in Controler by using SET_ATTRIBUTES method.
So,can you please tell me , what might be the reason for this.
CODE :
In View :
<htmlb:inputField id = "v_matnr"
value = "//material/v_matnr" />
In cotroler(do_request) :
view->set_attribute( name = 'material' value = me->material ).
Note : material is model instance here.
In model :
select matnr ersda mtart mbrsh matkl meins
from mara
into corresponding fields of table it_matgendata
where matnr = v_matnr.
Regards
Sandeep REddyThere are two things to consider.
1.
First you need to read the value from Formfields, then only you can able to send the value. then move the v_matnr value to model material->v_matnr.
read the form fields with the id v_matnr and get the value, and move it to model attribute.
2. Make the application Statefull.
Check it once and getback. -
I'm doing a scan around a line by sampling data 360 degrees for every value of z(z is the position on the line). So, that mean I have a double for-loop where I collect the data. The problem comes when I try to plot the data. How should I do?
Jonas,
I think what you want is a 3D plot of a cylinder. I have attached an example using a parametric 3D plot.
You will probably want to duplicate the points for the first theta value to close the cylinder. I'm not sure what properties of the graph can be manipulated to make it easier to see.

Enterprise JavaBean Model context mapping problem with dates from CAF BO
Hi Experts,
using CAF BO inside WD Java is a little bit problematic!
The CAF core Datatype "Date" is exposed as "javax.xml.datatype.XMLGregorianCalendar".
This datatype is not bindable to context attributes, cause wd is only supporting native java types.
in this case, a java.sql.date is needed.
What is the best practise to use JavaBean Models (CAF BOs) with attributes of type "Date"?
The normal Adaptive RFC Model imports ABAP Dates as java.sql.dates!
Using CAF external services, all ABAP Dates are exposed also as XMLGregorianCalendar.
How can i use/bind such models with less programming effort?
Best wishes,
HolgerHi Roelof,
CAF automatically decides which datatypes are used. It is not possible to change the used datatype
for imported external RFCs, so all ABAP Date Attributes will be typed as XMLGregorianCalendar.
This is different from the Web Dynpro Adaptive RFC Model, where ABAP Date Attributes are
converted as java.sql.date.
Best wishes,
Holger
