Hi:
how/where can I obtain the "Network data Model Visualizer" to display network models?

Is there an other way to visiualize the Network data. Does any GIS System (ESRI ArcGis, Intergraph Geomedia, etc.) support the Network Model?

Path direction in Oracle spatial network data model

Hi all,
can any one help me how to implement path direction using oracle network data Model?
We are using Oracle Spatial database. there is one feature called network constraint in Network data Model. but how to implement path direction of my Network ? Please help me any one

The path direction in a Spatial network is enabled at creation time when calling the create network procedure such as SDO_NET.CREATE_LOGICAL_NETWORK. If you describe the Create procedure you're using you should see a IS_DIRECTED argument, which when set to TRUE will enable path direction. Then just ensure that your links are created in the right direction -specifying correct orientation for start node and end node.
Cheers,
Stuart.

How to use NetworkConstraint in Network Data Model?

e.g. In a transportation application, you may drive from Node1 to Node2 along Link12, and from Node2 to Node4 along Link24, but you can not 'turn-left' from Link12 to Link24, how to restrict this in Oracle Spatial Network Data Model?
Is there any examples?
Thanks a lot.

The only way I know to do it, is to have a more complex node model. Instead of a simple node joining links 12 and 24, you need several at that point that link the streets. For example, with a standard four-way intersection, each end of the streets would have a node (warning CRUDE drawing):
..A
B.+.C
..D
Links between those nodes could have directional restrictions, or not even exist at all between any two. So, you could set it up such that From D to A and B to C you can go either way. For right turns, D to C, C to A, A to B, and B to D are directional. For left turns, C to D, A to C, and B to A are directional, with no D to B link existing.
Hope that makes sense.

Network data model for public transport

Hi,
I've been playing with Gis for the last 10 years and now I am enrolled in a project to find best way to go from one point to another in Barcelona (Spain) locations, using the public transport network.
The goal is to get a route, from one address to another (both given as inputs), formed by:
-     a 1st piece of path walking to the bus stop
-     a 2nd piece of path involving the bus used to go from one bus stop to another
-     optional 3rd piece of path with a second bus
-     the last piece of path to walk from the destination bus stop to the destination address.
This is a nice problem to resolve with a quite good looking software like the Oracle NDM. I know the big problem will be to put all the data in the right format.
But the question I’d like to share with you would be to approve or improve the algorithm I am thinking to resolve this:
STRUCTURE
Network Data Model NDM_1: creation of a SDO spatial network with all the streets and cross-roads to walk through
Other NDM_2 to store the bus stops with the bus-route-linking information.
     The reason to put them separately is for easily maintenance (a priori).
     [A second approach perhaps would be to put the bus stops as nodes of NDM_1 also]
ALGORITHM
1. Look for bus-stops near the geolocated origin address. (say listing BS_ORIG_list)
2. Look for bus-stops near the geolocated destination address. (say listing BS_DEST_list)
3. Search through NDM_2 for possible correspondences between BS_ORIG_list and BS_DEST_list through single bus line or by two different bus lines applying a network constraint.
(if not correspondence found or if more than 2 bus lines needed, abort by app requirement)
4. Find the walking paths needed to complete the various routes found in step 3 to get from address origin to destination
5. Order the results by time spent or by meters to walk.
Sure there might be improvements to this solution and also other ways to face such a common problem.
Thanks in advance,
David Foix

Hi Andrejus,
Thanks for answering.
I read through your thread already...
I understand and agree it would be a multimodal network. But what would that mean in the time of storing the data and asking for the route?
But I am still doubting the way to query for the resulting route. Having two adresses to join, would there be a nice function or procedure to ask for the route giving preference to walk the minimum meters and use preferently the bus network?
Or should I rely on the first algorithm I proposed? I thought there would be a nicer solution.
In your case, "road transport, railway transport, naval transport and air transport" I understand it would be a case to use different networks as they don't share spatial geometry, only some nodes..isn't it? Did you have the need to join all of them to find route solution giving preference to one of them?
Regards,
David

Populating One way path in our Network data model

Network Data Modeler Source

I have been working on building PL/SQL to extract Network models from well formed road shape files. I have successfully built a rather large road network and would like to add some features to Oracle's Network Data Model Editor to assist with final editing and add the pl/sql extraction module. Does anyone know if Oracle has released the source for this or if they are planning to?
Thanks

Hi,
Please see the Data Modeler Forum message option Show Source/Target Name “on” in the logic model for an answer to this question.

Oracle network data modele on mapviewer

bonjour , goodmorning
English:
I have an application of oracle network data modele witch contains node , link , plink and path tables. and i like to view this whith mapviewer application on web page, i was setup mapviewer 10.1 with OC4J and i saw the mvdemo without errors ... please get me the steps to do for visualizing my network.
Français:
j'ai mon propre réseau oracle network data modele et je voudrais le visualiser avec mapviewer sur une page web. le réseau contient les quatres tables necéssaire et pas de probleme dans ce coté. j'ai bien installer mapviewer avec le serveur OC4j et j'ai visualiser l'exemple mvdemo sans aucun probleme... SVP indiquez moi les etapes a suivre afin de visualiser mon reseau.

First may I recommend that you use the latest MapViewer quick start kit, which is 11g R1.
On your mapviewer web site, if you click the "Demos" tab, there is a link to a simple Network demo page. Have you tried using that? You should populate it with your own network data (network name et al). Let us know if you need more information on how to make this demo work with your data.
thanks

Problem reading a network (Network Data Model)

Hello,
I'm trying to create a network for routing. I can create and write this network fine but can't read it.
Currently I'm using the PL/SQL API but have also tryed the Java API (both present the same problem).
The following PL/SQL gives the below error:

XML Parse issues when using Network Data Model LOD with Springframework 3

Hello,
I am having issues with using using NDM in conjuction with Spring 3. The problem is that there is a dependency on the ConfigManager class in that it has to use Oracle's xml parser from xmlparserv2.jar, and this parser seems to have a history of problems with parsing Spring schemas.
My setup is as follows:
Spring Version: 3.0.1
Oracle: 11GR2 and corresponding spatial libraries
Note that when using the xerces parser, there is no issue here. It only while using Oracle's specific parser which appears to be hard-coded into the ConfigManager. Spring fortunately offers a workaround, where I can force it to use a specific parser when loading the spring configuration as follows:
-Djavax.xml.parsers.DocumentBuilderFactory=com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl But this is an extra deployment task we'd rather not have. Note that this issue has been brought up before in relation to OC4J. See the following link:
How to change the defaut xmlparser on OC4J Standalone 10.1.3.4 for Spring 3
My question is, is there any other way to configure LOD where it won't have the dependency on the oracle parser?
Also, fyi, here is the exception that is occurring as well as the header for my spring file.
org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException:

I ran into this exact issue while trying to get hibernate and spring working with an oracle XMLType column, and found a better solution than to use JVM arguments as you mentioned.
Why is it happening?
The xmlparserv2.jar uses the JAR Services API (Service Provider Mechanism) to change the default javax.xml classes used for the SAXParserFactory, DocumentBuilderFactory and TransformerFactory.
How did it happen?
The javax.xml.parsers.FactoryFinder looks for custom implementations by checking for, in this order, environment variables, %JAVA_HOME%/lib/jaxp.properties, then for config files under META-INF/services on the classpath, before using the default implementations included with the JDK (com.sun.org.*).
Inside xmlparserv2.jar exists a META-INF/services directory, which the javax.xml.parsers.FactoryFinder class picks up and uses:
META-INF/services/javax.xml.parsers.DocumentBuilderFactory (which defines oracle.xml.jaxp.JXDocumentBuilderFactory as the default)
META-INF/services/javax.xml.parsers.SAXParserFactory (which defines oracle.xml.jaxp.JXSAXParserFactory as the default)
META-INF/services/javax.xml.transform.TransformerFactory (which defines oracle.xml.jaxp.JXSAXTransformerFactory as the default)
Solution?
Switch all 3 back, otherwise you'll see weird errors. javax.xml.parsers.* fix the visible errors, while the javax.xml.transform.* fixes more subtle XML parsing (in my case, with apache commons configuration reading/writing).
QUICK SOLUTION to solve the application server startup errors:
JVM Arguments (not great)
To override the changes made by xmlparserv2.jar, add the following JVM properties to your application server startup arguments. The java.xml.parsers.FactoryFinder logic will check environment variables first.
-Djavax.xml.parsers.SAXParserFactory=com.sun.org.apache.xerces.internal.jaxp.SAXParserFactoryImpl -Djavax.xml.parsers.DocumentBuilderFactory=com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl -Djavax.xml.transform.TransformerFactory=com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl
However, if you run test cases using @RunWith(SpringJUnit4ClassRunner.class) or similar, you will still experience the error.
BETTER SOLUTION to the application server startup errors AND test case errors:
Option 1: Use JVM arguments for the app server and @BeforeClass statements for your test cases.
System.setProperty("javax.xml.parsers.DocumentBuilderFactory","com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl");
System.setProperty("javax.xml.parsers.SAXParserFactory","com.sun.org.apache.xerces.internal.jaxp.SAXParserFactoryImpl");
System.setProperty("javax.xml.transform.TransformerFactory","com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl");
If you have a lot of test cases, this becomes painful.
Option 2: Create your own Service Provider definition files in the compile/runtime classpath for your project, which will override those included in xmlparserv2.jar.
In a maven spring project, override the xmlparserv2.jar settings by creating the following files in the %PROJECT_HOME%/src/main/resources directory:
%PROJECT_HOME%/src/main/resources/META-INF/services/javax.xml.parsers.DocumentBuilderFactory (which defines com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl as the default)
%PROJECT_HOME%/src/main/resources/META-INF/services/javax.xml.parsers.SAXParserFactory (which defines com.sun.org.apache.xerces.internal.jaxp.SAXParserFactoryImpl as the default)
%PROJECT_HOME%/src/main/resources/META-INF/services/javax.xml.transform.TransformerFactory (which defines com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl as the default)
These files are referenced by both the application server (no JVM arguments required), and solves any unit test issues without requiring any code changes.
This is a snippet of my longer solution for how to get hibernate and spring to work with an oracle XMLType column, found on stackoverflow.

Data Modeler in a network

At one of my projects there's a question about what is the best to deploy Data Modeler in a network. They prefer to use it in a Citrix area.
Two very important topics of what they are planning to do in Data Modeler:
Drawing ERD diagrams.
It should be possible to edit a diagram by more than one user on different workstations.
Use of transformation scripts.
Scripts can be used by more than one user on differect workstations.
I found out the content of this scripts is stored in dr_custom_scripts.xml. At this moment it seems we can't save the scripts while running DM on Citrix.
Does anyone have any experience with this issues?

I have used SVN (Subversion) when there was a need for multiple users of the same design. Each can check out the model to their workstation and save changes to SVN. When one user saves a change, those changes are then visible to the other users as inbound changes. If one user makes changes to something another user also changed, they will get a conflict resolution dialog to resolve the issue. This seems a better solution than trying to share a single model folder via Citrix.
Files such as defaultdomains.xml and dr_custom_scripts.xml can also be saved and shared via SVN. I think there may be another discussion on how to do this on the forum already (I think I asked about it a year or so ago).

Data modeler in 2.1 - how to export metadata

How do you do an export in the 2.1 EA for the data modeler? I..e do a 'bottom up' model?
The documentation is written for the standalone datamodeler, file-import/export. How do you do it in 2.1?
Edited by: Bazza on 27-Oct-2009 03:54

Hi,
standalone Data Modeler is cost option. Data Modeler Viewer is bundled into SQL Developer 2.1 - it's free. You can do following with viewer :
1) Open designs created with Data Modeler - it's in read only mode
2) Visualize tables and object types from SQL Dev browser when there is no open Data Modeler design - select tables/views on SQL Developer browser tree and drag them on relational model window - FK are imported if parent table is among selected or already is imported; for object types - they should be dropped on Data Types model window. This works for Oracle and SQL Server - we are going to support it for all databases supported by Data Modeler (including JDBC import). And you can do some rearrangement of tables but the rest is in read only mode - no additional import/export.

SQL Developer Data Modeler suggestions

Not sure where to post this (unable to connect to the blog from work due to network restrictions), hope this is the correct forum.
I am testing out the Data Modeler product. I've got a large database that I want to reverse engineer, then work with the resulting model. I used the import feature which successfully imported all 1849 tables from my schema. However, this created a diagram which wasn't really useful. A couple of things I believe would be useful.
1. Add better connectivity between the browser that shows the table listing and the diagram. When I click on a table, I'd like the corresponding element in the diagram to be highlighted (and vice-versa). Also, an option to have the diagram show that table would be useful (maybe a ctrl-click or shift-click).
2. Subviews - I don't see an easy way to add to a subview once it is created. So, add an option to the browser and diagram right-click menu to "Add to SubDiagram". Currently the diagram allows you to create a subdiagram, I didn't see an add option.
3. More keyboard shortcuts. Specifically, CTRL-Z to undo, CTRL-Y to repeat.
4. Defined column types. You've got naming rules, but I'd like to be able to define columns as a predefined type, like "Dollar Amount", which would make my column become a number(9.2) or something like that.
That's it for now - may be more to come.
Don

Hi,
Thanks for the feedback. Most of these are in the product:
+1. Add better connectivity between the browser that shows the table listing and the diagram. When I click on a table, I'd like the corresponding element in the diagram to be highlighted (and vice-versa). Also, an option to have the diagram show that table would be useful (maybe a ctrl-click or shift-click).+
Go to Tools > General Options: Select Diagram and check the synchronize with tree option.
+2. Subviews - I don't see an easy way to add to a subview once it is created. So, add an option to the browser and diagram right-click menu to "Add to SubDiagram". Currently the diagram allows you to create a subdiagram, I didn't see an add option.+
There are threads in the forum about subviews and you can look at the demos available online on the [Data Modeler|http://www.oracle.com/technology/products/database/datamodeler/index.html] page - we'll be adding more, but the import from Data Dictionary demo talks about subviews.
In short, select a few objects, right-click and create subview from selected, or right-click on the subview node in the browser and select new subview, and then drag the tables you want onto the new diagram.
+3. More keyboard shortcuts. Specifically, CTRL-Z to undo, CTRL-Y to repeat.+
We will be adding more shortcut keys.
+4. Defined column types. You've got naming rules, but I'd like to be able to define columns as a predefined type, like "Dollar Amount", which would make my column become a number(9.2) or something like that.+
These are Domains. Select Tools > Domains Administration, and add your domains.
I'm working on adding short demos for all these features and we'll build these up over time.

Does SQL Developer Data Modeler fit-in??

Hi Everyone,
Wish you happy new year 2011.
Does SQL Developer Data Modeler support conceptual, logical and physical in our modeling or only logical and physical?
We all use Erwin for modeling. Erwin works without database repository storing models in desktop folders and provide additional reporting. I find some place SQL Developer Data Modeler talked about repository need.
Does SQL Developer Data Modeler store the models in local/network folders instead of Database server?
What are the functions need database based repository to work with SQL Developer Data Modeler?
We are thinking of using SQL Developer Data Modeler for our conceptual, Logical, and data dictionary need. Will it help in our need?
Do we need to face any surprises on using SQL Developer Data Modeler for our need?
Thanks in sharing your experience and helping me out.
RI

1) Do we need to have Oracle database at back end to work with SQL Developer Data Modeler?No, Data Modeler use Oracle database only if you create reporting repository.
Data Modeler is free, you need database license only if you want to log service request
2) Will SQL Developer Data Modeler create any tables (as backend repository ) in Oracle database to store Model details? no
3) Do we need to create reporting schema in backend oracle database to generate reports of SQL Developer Data Modeler's items such as Entity/attributes etc?no, reports can be created out of current loaded design. However having reporting repository will give you additional benefits - history (reports can be generated for every snapshot of your designs there) and multi-user usage, you can create your own reports
4) Do we to use SQL Developer Data Modeler reverse engineer from DB2, SqlServer, Terra data etc?Data Modeler has full support for Oracle, DB2/390, DB2/UDB(LUW) and MS SQL Server. Reverse engineering from other databases (including Terra Data) is at generic JDBC level - you'll get some and some will be missing (no check constraints for example).

SYS DATA_PUMP_DIR /opt/oracle/app/oracle/product/11.2.0.1/rdbms/log/
SYS XMLDIR /opt/oracle/app/oracle/product/11.2.0.1/rdbms/xml
What can cause this problem. I have the same issue with the older version of the data modeler
Thanks

Hey if you want me too I can create a tar/sr.
It happens even when I log in as sysdba. The three directory objects on the file system are all owned by oracle and oracle can rwx into those.
My user can see XMLDIR but does not have read/write on the directory object all other it does have read write.
Thanks.

Data Modeler unable to connect to DB

I am using OS/X 10.8.5. I have SQL Developer and Instant Client 11.2 installed and working fine.
I have recently installed Oracle Data Modeler 3.3.0.747 and am trying to synchronize my model with the DB.
When I try and add a connection if I set the connection type to TNS (which works just fine in SQL Developer), it doesn't show any of my tnsnames.ora entries in the 'Network Alias' drop down.
So I instead tried creating a connection of type 'Basic'. That _seemed_ to work OK - in that when I clicked 'Test' on the connection it returned success. However when I tried to use that connection it returned immediately with the error 'Closed Connection'.
Any suggestions would be gratefully received.
Steve

Maybe you need to install Oracle instant client . I had something similar to what you describe - can't rememeber if it was exactly the same , but I (think) I fixed it that way
