Is there a way to make the search of texts in the database?
I was wondering if there is a way to push the search of texts in the database.
Specifically, I'm looking for a way to create a DocumentTermMatrix and work on it in the database.
Company R Oracle provides any type of text mining functions or is there a way to push the standard package R tm is run in the database?
Thank you
Mike
Mike,
Oracle Enterprise R does not include the extraction of specific text features, but because it can exploit data in extraction of features Oracle database, it may inherit the ability to analyze textual data using the tm or other related packages of NOTCH. We provide examples of use of packages open source R with ore in the Oracle Enterprise of R User Guide and training materials. Here are some links to help you:
See the section called "Run R calculation in Oracle Database":
http://docs.Oracle.com/CD/E11882_01/doc.112/e36761/using.htm#OREUG163
See slide 25:
Any R package used with ore must be installed with the R on the database server and client of R.

I multilple of relational databases, our aspx developer was able to link them by using the stored procedure, but because I would like to convert the work in coldfusion, I found difficulties in the use of stored procedures to query all the relational databases, as the coldfusion connection it takes manually to each database. Here's the scenario:
I have 5 databases MS SQL: [img1, img2, img3, img4 and descriptionDB]
the "descriptionDB" contains the text and id identification information will be linked to a hexadecimal image in one of the databases [i] img images.
How can I do a query using coldfusion to display the images and their texts related!
You may be looking to fix something that isn't broken. If stored procedures have worked in asp, there is no reason for them to not work in the CF. The only link that you need is the db with the stored procedure.

I have a very simple question for one of you the pros of the Oracle. I do a book for school and the question is... Describe the type of data that will be contained in a relational database managed by Oracle. Any ideas?
Thank you
Good lookingA relational database can be used to manage any type of data that the database, business owner, wants to store!
The suite of products of Application Oracle, PeopleSoft, and SAP when under Oracle store almost all information related to the management of the company business: shipping, receiving, order entry, handling, inventory, engineering, production and finance is some of the major categories of data stored in Oracle.
You can also store audio and Visual information and all documents in the database.

I have an old relational database, Base of power. Need to transfer to new computer
I have an old relational database, basic power, written for the old BACK who also works with Windows 3.2 and Windows 95. I just got a new Toshiba laptop, running windows 7. He needs to do to run this program. I have old professional documents on it and a large geneagology that I am trying to keep up to date. Can you suggest one new relational database that are other than the access that will allow me to transfer my old files?
You might try DOSbox http://www.dosbox.com/
If you have a copy of Windows 3 or 95, you can try running under Virtualbox http://www.virtualbox.org/
OpenOffice http://www.openoffice.org/ includes a database program.
Otherwise, you can migrate your data to any Windows 7 compatible program. You left it too long as migration is not likely to be easy.

EMP tables in the relational database
Hello
Can you please let me know what is the tables are actually created in the SCHEMA (Shared services) or EAS in the relational database. It's when configuring EMP that tables are automatically created in the database?
Appreciate your comments and thank you for your time.
Thank you
HariYes the tables are automatically created and filled at the point of configuration.
See you soon

Hello
My question is as below
We intend to deploy essbase version 11.1.1.3.0 on platform Linux RHEL5. I want to know the design of relational database, we would need for shared service and EAS to configure and use according to the installation document.
-At least the documentation mentions is 100 MB. Is this a possible size?
-What happens when this 100 MB runs out? Will be this errror outside? It truncates and write again in system tables needed for shared services?
-Lets say I have about 800 native users and since LDAP OPEN will disappear with this version as well so it will be written to the relational tables as well.
-What would be a possible size in this case. Will be around 1 GB to 2 GB suffuce?
Thank you
PrasadI do not know what database you are using, but if it's Oracle, you can set the size to autoextend by a set for example size 50 MB.

I apologize in advance for the banality of this question, I have been the design of Foundation for my business for years and I am comfortable with html and recently designed a site complex havig susssed .css and coldfusion code written however dw.
I CANNOT MAKE THE LEAP TO GET MY HEAD around RELATIONAL DATABASES and want to integrate some forms of dynamic application (which I can code in CF).
Can someone point me to a resource that will walk me but how to build a simple relational data base (then a complex) that send me to sleep or make sure my eyes glaze.
Its a brain block which now cause me stress, but I just don't understand...
Save me
TaNo worries. I can sympathize with trying to grasp new concepts. problem is that double signage makes just more difficult for people to follow the wire (s).

Restrict access to the Page of the user in the relational database
I have a relational database with two tables on a common ID field. The user can access all their entries in the child table with simple SQL queries and then select from a list of correspondence which of its documents records in the child table that they wish to change (i.e. ['ID'] ParentTable, ChildTable ['ID'])). Registration is then displayed using $_GET passed through the URL as parameter "recordID". However, when the user is connected and accessing a folder that matches the query, they can then enter another "RecordID" number in the URL and go to any record in the table child whether they are 'owner' of the record or not.
I tried to put a statement of equivalence in the authorization user code to restrict the access to the child records users since ParentTable ['ID'] == ['ID'] ChildTable only when you are connected the user accesses the records they created previously. (In other words, when a user type a different "RecordID" in the URL, the ParentTable ['ID'] and ChildTable ['ID] are not equivalent.) The code that I entered in the authentication of the user generated by DW is as follows:
If ((isset ($HTTP_SESSION_VARS ["MM_Username"]) & & ($row_ParentTable ['ID'] == ['ID'] $row_ChildTable))) {}
...
Is still not accessible, even if tests show the ParentTable ['ID'] and ChildTable ['ID'] are not equivalent
Any ideas on how to restrict access to the child records "unknown"? I'm sure it's relatively simple, but I'm having trouble to get through this obstacle.
Thank youThank you, Philo. In fact I got it to work by initializing a session variable of tha parent ID of the table and comparing it to the variable ID of child table, then using a header redirect in case of inequality. Part of my problem was where I put the code in the page. Anyway, it works now. It seems that the answer is always just after you have posted the question.

How to create an ODBC connection to import objects to relational database
Can you please give me a step by step explanatiuon how create an ODBC connection to import objects to the relational database?Hello-
The path is relative where you store your files for Oracle. It should be similar to something like this:
.. \oracle\product\11.1.0\db_1\NETWORK\ADMIN
the 'NETWORK\ADMIN' part should always be the same. If you have difficulties to find, just a Windows Search "tnsnames.
I hope this helps!
Kind regards

Planning Workflow - metadata in the relational database
Hello
In the metadata in the relational database, there is only an ID for almost every column. I would like to have names for these IDs so I can understand more clearly what is happening. Mainly concerning the workflow, I like to check in the database, what happens.
Is this possible?

Most of the IDS will link to the table of hsp_object
So an example of discovering the name for the first two columns (plan_unit_id and scenario_id) in the hsp_planning_unit table
Select puobj.object_name as 'PlaningUnitName', scenobj.object_name as 'Scénario' of
pu plansamp.hsp_planning_unit, plansamp.hsp_object puobj, plansamp.hsp_object scenobj
where pu.plan_unit_id = puobj.object_id
and pu.scenario_id = scenobj.object_idYou can extend it to include other columns such as version, entity...
additional columns that don't point to hsp_object are
last_column colum = 0 = promote; 1 = rejection; 2 = approve; 3 = approval; 4 = start; 5 = exclude
process_state = 0 is not started.; 1 = first pass; 2 = under review; 3 = approved; 4 = closed; 5 = unsigned outOk?

Unable to create XML from an existing relational database

Using OSX El captain on a desktop iMac. iPhoto 9.6.1
I tried to buy my book - this box appears - TEXT by DEFAULT - your book seems to have default text that has not been modified. Printed books will not include this text. Does this mean that all my text will not print?
I've been twice now and change the text of Bradley Hand to the Blackboard to Helvetica Neue - which seemed to be the default. Message remains displayed. I don't know what else to do. This is my third book over the years, but the first with this problem. Can someone advise please?
Thank you Davina
It is not a problem of fonts. It is the problem of the sample text entered by the models.
The error message means that there is a text field in your book which is still on show at the text included by the model, and you will need to replace this text with your text. This textfield might be hidden behind a picture.
If you create a preview of the book, such default text is omitted. Have you compared the preview of what you see in iPhoto? Text that shows in iPhoto, but not in the preview will be such default text.
For example, the section 'Topic of this book' on the flap back in some themes is a default text that should be replaced by your own legend:
