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).

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

here is oneway column if value is 1 then it is one way otherwise bidirectional. I created data model but i am not able to populate path direction

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

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).

Data Modeler 3 (EA1): Connection issue when connecting to oracle 11R2

Hi all,
When I try to create a connection object for a oracle 11r2 database I get the following error:
ORA-00604: error occurred at recursive SQL level 1
ORA-22285: non-existent directory or file for FILEEXISTS operation
ORA-06512: at "SYS.DBMS_LOB", line 725
ORA-06512: at line 5
when I test the connection.
I have checked the oracle 11r2 instance and have 3 directory objects and all are correct;
SYS ORACLE_OCM_CONFIG_DIR /opt/oracle/app/oracle/product/11.2.0.1/ccr/state
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

RuleAuthor : error importing XML Schemas into Data Model

Hi,
I have problems during import XML Schema in my Data Model.
I'm following these steps:
1) Click Definitions tab;
2) Click XMLFact;
3) Click Create
4) I enter the path for the schema and the directory to store JAXB-generated classes. In this directory every user has all permission (777).

I cannot find the solution!
Can someone help me?
Thanks.

Do you still have enough disk space available on your file system to store the different xml-facts the RuleAuthor will create for you?

Data Modeler EA1: Running off LAN drive Problems.

Installed Data Modeller with the JRE included on LAN drive succussfully.
Attempted to run the Data Modeller from LAN drive, but there were many problems.
1. Preferences window had java errors
2. limited functionality.
Solved by installing on local drive.
Need to update install instructions and documents to reflect installation requirement of using local drive.

Thanks Philip.
I don't think that is the answer. My workstation is locked down very tightly, which is why I first attempted to install the software on my LAN drive. I think that for some reason java network detection is turned off, so that java has problem finding components with the local sub-directory on the LAN drive.
I am not certain if this helps you.
Thanks again.

Excel Workbook with Excel Data Model stored on SharePoint - daily refresh

I'm not sure if this is exactly the right forum but I'm hoping that someone here can either answer or point me in the right direction.
I have an Excel Workbook with an Excel Data Model.
The Excel Data Model uses SQL to contact our data warehouse and pull through data into tables.
We are storing the Workbook on a SharePoint site and viewing it using Excel Services.
The data in our data warehouse is updated daily and so I would like to refresh the workbook daily and remove the option to refresh the data in the browser.
Is this possible with a workbook that has an Excel Data Model (I've seen lots of posts that relate to workbooks with connections to tabular models).
Thanks
Paul
