Differentiate the tables changes and no changes do not

Hello

I am relatively new on (I've always been a sort of paper/felt for Whiteboard guy) formal data modeling tools.

On my question/Scenario:

I have a warehouse of data with a few hundred tables inside. When changes are made to the data warehouse, we're supposed to present an ER diagram preferably with tables in one color, tables be changed to a different color and the tables does not change does not to another more neutral color.

Here is my current process

(1) import of relevant existing tables in the data dictionary
(2) create tables or change existing tables
(3) change the type of array for the modified tables and dimension for new tables. The existing tables, I leave it as what.

Success with this process generates a diagram that fits my purposes, but I have a hunch that I'm not using better methodology. What is a better way to do this using the oracle sql data model (version 3)

What you certainly works, but a better approach would be to define new types of classification rather than use the Dimension or fact.

Then go here:
Tools-> preferences-> data-> diagram maker-> Types of Classification.

Press the Green plus sign to add a new type.
Add two new types: new and changed and assign each a unique color.
Press 'OK' to save.

Now, when you go back to the diagram, you will have two new types from.

  • How to add data to the table changed in sql developer at Apex and vice versa

    Hello

    I had tables of database with sql developer. But now, I have modified the database (new tables added + changed the data in the tables). However, in the Apex, I the old database. Is it possible to get the new Apex database with the data of the table changed so this database in both places (sql and apex developer) is exactly the same... Also the other way around.

    Thank you

    The database schema that contains the tables, is it associated with the workspace even you are searching through the APEX product t development?  Why I'm asking is, if they are the same schema, the tables that you MODIFIED should be appear in the sql for APEX workshop part.  Now reports and forms will NOT see the changes (unless you have actually added or updated definitions for column).

    Can you explain what exactly you were doing the SQL Developer to the tables in your schema?

    Thank you

  • Why the processor info and his memory will not display on the properties of the computer.

    When I go into properties of the computer, the processor information and memory installed in not illustrated, the fields are empty or say no information available.   How can I fix it?   I can see the processor information using Device Manager.

    In addition, SYSTEM side is not displayed but I see when I select the tools and performance information.

    The computer seems to work fine otherwise, I just want to know how and why the information is not seen in the System Properties screen.

    If the system is stable and functional, I don't think anything really to worry about.

    Hi cjohnm,

    You can use the 5 Lightroom Catalog and improve it in Lightroom 6, therefor all folders and collections will be identical in both version.

    Open the Lightroom all holding the key Alt/Opt and select only the 5 Lightroom Catalog and it will switch to it.

    Let us know if that helps.

  • Synchronize the table changes

    Hello

    OWB 11 g R2, oracle DB 11 g

    For some reason... I changed my table at the DB level definitions, added a few columns and load the data using some scripts in this table. I have this table in OWB (old version without these additional columns), is any way to synchronize table of DB to OWB definitions? or I have to redo all changes in OWB? If I deploy by changing the table in OWB manually and then deploy, I guess that it does not allow to upgrade, but if I do not replace, there is a risk of losing data.

    Is it possible to do that without losing data?


    Thank you
    HESH

    Hi Hesh,

    Yes, this applies if you have created the table through OWB or DB, if you have made changes to the DB level table you can reimport the table on OWB and synchronize, you must modify the object in OWB manually, it is a tedious process if the changes are enormous.

    Thank you and best regards,

  • Adding a column to the table-> IR and form

    The database has been changed to add a column to a table. It is desirable to update the form generated 'on a Table with a report. What I have to delete the pages and redo them with the new column or is it possible to get just the set DML to update? (change the report and the form is easy, it's that the DML is updated tha I can not understand.

    Hi Bill,

    out of the box, you get an "automatic line (DML) treatment.
    If you ensure that the new column is the right column of the mapping database in the source section of the page element, then the DML is automagically picking up your new column.

  • folder Windows NT has files listed in the table TextService and I can not delete or remove them due to trustedinstaller being above me, the administration system. How can I remove these?

    These files do not allow me the owner of this computer to support in the permissions area or allow me to delete them in windows safe mode. I also can't do anything with the permission of edition since the Trusted Installer is the only access to those files.

    The file is Windows NT with two subfolders and I can't access or remove one of them.
    I want to delete these files to windows and my computer, how do I remove the Installer only access?

    I was finally power with some help of a video get youtube the answer that I need to take in charge and delete the files with out having to down load any software.

    files are gone from my computer after using the edit view and change the file sharing, then enter the permissions and change permissions for folder with my user as owner.
    This non-greyed out the locked area to finally remove the files and allowing me to access the files.

  • The Stimulus of the Table load and run in the stream or target RT via Ethernet?

    I need to re-read a CAN track with the high fidelity and sequencing of rapid fire. The PC operating system is in the way too much to be able to control this tight of the moment. It must be managed within the target in real time.

    Do the stimulus of the table the stimulus replay load data to the RT, and then run the target of RT, or don't work space running on the PC the data flow to the RT for execution? Streaming would be subject to delays of PC operating system and network transport times.

    Thanks in advance for your help.

    Table of stimulus data gets loaded completely in memory on the target of RT and are replayed from there. PC or network delays has no effect on reading as soon as it starts.

  • How to save the table column and row headings

    I have a table where I activated the column and row headings.  Once the table is loaded with data, I would like to save the contents of the table, including the column and row headings in a text file.  The crux of "value" property returns only the content of the table, not the row and column headers.  I could use "header line chains []" and '[] column header chains' property nodes as well, but I'm in the island there is an easier way.  Looks like adding the headers of lines would be difficult.  Any ideas?

    Thanks in advance.

    Here is a way. The construction with the empty constant is to provide to the left corner of the table where there is no data.
