I'm gonna execute a DMN Diagram in the external engine, I couldn't find any solution to export the DMN diagram in a standard omg format.

When developing a relational database model for an application one can create for example an entity-relationship model, e.g. using MySQL Workbench. Although documenting those models using UML class diagrams is also very common. Both methods can be seen as standard way to go when making up an architecture for a project.
Question: what is the standard way to go for no-SQL database models?
I want to design a model for MongoDB and/or ElasticSearch which are basically arbitrary JSON stores. But I need to document at least the fields and the "relations" to each other to give a reference structure.
Is there any tool (diagram language?) existing? I looked into the documentations and found no hint for an answer. I'm aware of text files and know that one could simply write a text file with an example JSON. But I'm looking for a little bit more sophisticated and polished solution.
Any ideas or standards here?
Moon Modeler for MongoDB is a tool for visual definition of noSQL structures. It allows you to draw diagrams similar to entity relationship diagrams - with nested types/embedded documents.
I have to implement on Enterprise Architect a GIS model compliant to Inspire directive. Then, I have to create the ddl code to insert in postgres to create the physical structure of my db.
The problem is that I don't know what type of diagram I have to set up on enterprise architect.
Now I have created a domain model and imported in my foundation schema the classess directly from the Inspire repository (http://inspire.ec.europa.eu/index.cfm/pageid/2/list/datamodels). I see the issue when I create the ddl and I import this on postgres because postgres does not recognize the Inspire types (eg. CharapterString, GM_Point).
I hope that I did make myself clear.
I have build a supervised learning model in R, and exported the model/decision rules in PMML format. I was hoping I could link the PMML straightforwardly to MongoDB using something like the JPMML library (as JPMML integrates well with PostgreSQL).
However, it seems the only way to link MongoDB to my PMML xml file is to use Cascading Pattern through Hadoop. Since my dataset isn't large (<50GB), I don't really need Hadoop.
Has anyone used PMML with MongoDB before that doesn't involve having to go down the hadoop route? Many thanks
Basically, you have two options here:
Convert the PMML file to something that you can execute inside MongoDB.
Deploy the PMML file "natively" to some outside service and connect MongoDB to it.
50 GB is still quite a lot of data, so option #1 is clearly preferable in terms of the ease of setup and the speed of execution. Is it possible to write a Java user-defined function (UDF) for MongoDB? If so, then it would be possible to run the JPMML library inside MongoDB. Otherwise, you might see if it would be possible to convert your PMML model to SQL script. For example, the latest versions of KNIME software (2.11.1 and newer) contain a "PMML to SQL" conversion node.
If you fall back to option #2, then the following technical article might provide some inspiration to you: Applying predictive models to database data: the REST web service approach.
I have a relational model in Oracle SQL Developer Data Modeler with tables and relationships. Is it possible to export that relational model to a image file?
It is possible, but looks like is not very intuitive.
Zoom your relational model to the expected resolution (at least to be readable).
Go to File, then Data Modeler, then Print Diagram and selected the desired format.
This will generate an image file with your relational model with the current zoom level as the resolution.
Current path to printing model in SQL developer is:
File -> Data Modeler -> Print Diagram -> To ... File
I know this question is old, but I did figure out how to make it work using a different thread on stack overflow.
How to generate an entity-relationship (ER) diagram using Oracle SQL Developer
Is their any utility through which we can determine the list of database objects an Oracle Form or Report uses or the list of Forms and Reports that use a specific database object.
For Oracle forms/Reports 10g
There used to be a tool made by Quest Software "SQL Impact" but it is not supported any more.
The easiest way to do this kind of analysis is to convert all your fmb/rdf to xml and then write a script in Ruby searching for db object names.
Alternatively you can use JDAPI to iterate over forms objects, but there is no JDAPI for reports. Using JDAPI is much easier using JRuby, you can find sample scripts there:
