Hey everyone, i am currently trying to ddevelopa database for my PC support website. I am unsure of what fields go in what entities/tables. Could you please help
The entities consist of
Record Number

Problem Record Details
Problem Type
Problem Description
Problem Resolution
Problem Status
Client Name
Client Phone Number
Client Email
Technician Name
Technician Email Address
Date Completed
I believe the four tables should be of client, technician, problem and record. But i dont quite understand what to put in each table and the foreign keys required in each to work.
Thanks Alot

FOD schema installation with tutorial Database Development with JDeveloper
I followed the instruction online at http://www.oracle.com/technetwork/developer-tools/jdev/index-095536.html to install FOD schema. Errors displayed when call "run ant target -> buildall" were below:

But still got message - "BUILD SUCCESSFUL" at the end. Does anyone know how to solve this problem?
My intention of performing FOD schema installation was to follow the tutorial "Database Development with JDeveloper" at http://st-curriculum.oracle.com/obe/jdev/obe11jdev/ps1/databasedevelopment/obe_%20databasedevmt.htm. But I stopped at the last topic "Creating and Debugging PL/SQL Objects in the Database" ->"Running a SQL Script to Create an Object Type" when trying to create a object using script on the page.
This is the script:
------------------------------------------------start
REM
REM Create object ORDER_ITEMS_REC
REM
CREATE or REPLACE type ORDER_ITEMS_REC as object
ORDER_ID NUMBER(15),
LINE_ITEM_ID NUMBER(3),
PRODUCT_ID NUMBER(15),
QUANTITY NUMBER(6),
UNIT_PRICE NUMBER(8,2),
CREATED_BY VARCHAR2(60),
CREATION_DATE DATE,
LAST_UPDATED_BY VARCHAR2(60),
LAST_UPDATE_DATE DATE,
OBJECT_VERSION_ID NUMBER(15)
show errors;
--------------------------------------------------end
and the error message I got was
------------------------------------------------start
Error report:
ORA-01031: insufficient privileges
01031. 00000 - "insufficient privileges"
------------------------------------------------end
I was wandering whether the error of FOD installation could cause the error of the tutorial?
Any response will be appreciated.1. you dont have to insall Oracle database at the BO machine side, you just need any database to hold the BO repository.
2. you cant connect directly using BO, only Crystal reports can connect directly to R3 database, you need to have a BW in between.
extract your data into the BW, and let BO connect to BW using the BO integration kit for SAP solutions.
3. no you dont have to have 3 different machines, using one BO machine you connect to them all, but you may need build a BO environment, (Development, Production servers)

Database development with jdeveloper
Hi
Thank you for reading my post
is it possible to use Jdeveloper to develop Mysql databases ?
how i use its diagram <> database capabilities to forward a diagram to a mysql database ?
thanksHi,
For information on how connect MySQl to JDev, look in the Help for 'Working with Non-Oracle Databases' under 'Using Application Development Tools | Database Tools'.
And for Modeling Database Development with JDeveloper, you can find this tutorial useful :

Is there a web-only database development environment?
I have a database solution to create that only needs to be accessible via web browsers. I do not have an existing database, so it is not a matter of connecting an existing database to the web.
Is there a web-only database development environment that would allow me to create the entire database without some non-web database environment like Oracle, Access, 4D, FileMaker etc.
I guess what I want is a web-native database, I don't want to construct it in some environment that has to be "interpreted" in order for it to be presented to a web browser.Databases are databases. I'm not aware of any products that are specialized for web-only access. And I can't see such a product succeeding, since the existing products are already accessible via web programming.
I don't know what the remarks about "interpreted" mean so I can't help you there. -

Database development practise advise
Hi friends,
I am a fresher in the Development field..coming straight from college and certified in Oracle SQL so far, currently working on Pl/sql certification. I want to practise Quality industry Database Development as well as getting the experience that is required. Please help me with advise on what I should use as sample cases to work on or any other advise you can have. I have oracle 11G software installed on my machine.
What is the way forward?
Regards
TdewaI think besides the options told by Srini an Andy, reading the below book at this stage especially would be very helpful because it would be very tough to unlearn the wrong habits once you would come into the field.

Database Development perspective not in list
Hi
I know I'm probably being thick but I can't seem to find the Database Development option in my perspective list any longer.
When I download a fresh copy of ganymede from oracle (with the oepe stuff bundled) and load it up the perspective is
still not in the list. Can anyone point me in the right direction?
ThanksI've just downloaded OEPE 11g (Windows all in one zip file) at http://www.oracle.com/technology/software/products/oepe/oepe_11g.html. After I unzip it, I was able to go to Database Development perspective.
Did you use OEPE 11g update site and only installed OEPE plugins into your existing workspace? That should still work and you should be able to go to Database Development perspective as long as you are running Eclipse Ganymede (3.4) .
Database Development perspective is part of DTP. Go to Software updates and check your installed software. If you don't see various Data Tool Platform plugins, that might be your problem. You can use Ganymede update site to install Data Tool Platform plugins. Alternatively, if you install OEPE plugins using OEPE update site, it'll automatically install required Data Tool Platform plugins.

Database Development IDE's and Tools?
What do folks using Mac / OS use for Database development. I'm new to the mac after many years using PC's with SQL server and Visual Basic and such. I'd like to do some SQL and MSTransact like SQL and have a RAD tool or something that would allow me to develop tables and queries, views, etc,. I don't really like MySQL, but thought about it, but have never seen a Desktop Tool for it? I don't want a web or cloud tool, nothing against those, but prefer my old ways. :-)
Thanks so much in advance.
TimThe native data management approach can involve using the provided object graph data persistence tool (which is slightly different than a database) known as Core Data (Apple Core Data docs) — this'll be very different than what you're accustomed to.
For GUIs when you aren't rolling your own SQL code, there's Sequel Pro, Navicat and alternatives.
MariaDB and MySQL should be compatible, and there are kits for MySQL around for OS X. OS X Server includes PostgreSQL, but AFAIK that database is not particularly exposed by Apple.
Python, Perl, php, Ruby and related scripting languages all have database APIs, with varying degrees of portability. (These languages are among the closest analogs to Visual BASIC on OS X.)
If you're writing a client for a web service or ODBC/JDBC, or maybe (as I'm investigating) OwnCloud.
Xcode doesn't include generic database development mechanisms; NoSQL or SQL options, nor capabilities other than for Core Data.
FWIW, these sorts of programming question would be more common over in the Apple developer forums, too; more developers over there than around here.
You also now have some good web search terms, too. -
Database Development Perspective
Hi all,
I'm following the following tutorial: https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/00bddb57-456c-2b10-cc8d-b6980d75299b
It mentions a "Database Development Perspective" several times, where it seems I should be able to check the "Data Source Explorer" to see the default schema of the database created, and set a dictionary as a datasource.
Well, I'm ubale to find such perspective.
Probably it doesn't appear because of my developer studio version (I'm using 7.0.16). Is there someway I can get this perspective to show up? Maybe I need to download some kind of plugin? Or is there some other way to do what I intend to using the 7.0.16 available perspectives?
Thanks and regards!
Edited by: Alain More on Feb 17, 2009 6:23 PMHi,
1. Select the view on Window -> Open Perspective -> Other -> Database Development
or
2. Window -> Show View -> Other -> Connectivity -> Data Source Explorer
If you get an error using Maxdb like:
Unable to locate zip/jar in file system as specified by the driver definition <..sapdb_installation..>
\programs\runtime\jar\sapdbc.jar
3. Point to "sapdbc.jar" file. Use Windows search to find it and create the JDBC connection.
I hope this helps. -
APEX supports the TimesTen Database development?
Hi all,
Oracle Application Express supports the TimesTen In-Memory Database development?
Thanks,
JettHi Jett,
you probably wanted to post this question in {forum:id=137} or even {forum:id=244}, right?
Anyway, I don't think APEX supports TimesTen, as TimesTen doesn't have all required features and is (hence) not listed in the supported database versions of the [url http://docs.oracle.com/cd/E23903_01/doc/doc.41/e21673/pre_require.htm#i1009513]Installation Guide.

Any help in correcting this matter would be greatly
appreciatedFirst off, Dreamweaver even CS3, sucks at ASPNET, which is
the technology this is using.
I think Visual Studio 2003 is using ASPNET 1.1, The current
version of this technology is ASPNET 2.0, which is easier to use
What you can do is download free of charge Microsoft Visual
Web Developer from Microsoft, you'll need a few things - .NET
framework 2.0 and MS SQL Server 2005 Express to make everything
work better.
I think you'll see this as a better alerternative to
Dreamweaver and all of this is free from Microsoft.
If this were anyother technology, even traditional ASP, I
would say stick with Dreamweaver, but not with ASPNET
MS have also released something called Expression Web which
is great at ASPNET for putting front-ends on apps developed using
ASPNET -

Still can't download Developer Day Hands-On Lab Manual Database Development
I am trying to download the hands-on lab manual for Database Development and XML. I have tried right-click save and receive an error stating the file(s) cannot be read. Where can I retrieve these files?
Database_Development_Volume_all.pdf
xmldb_HOLs_2009_Part1_manual_April_2010.pdfHey Rahul,
The iTunes app is asking / telling something before the download hangs?
What you can do to check if it's a server, ISP or iTunes problem, is to make a direct download from Redmond Pie or OSXDaily just iOS not the firmware (unless you don't want to go back to a previous iOS version). Then do a manual update through iTunes, option + click Restore, choose the IPSW file and done.

XML Database Development with JDeveloper?
Hello, folks:
I am trying to create XML database through JDeveloper.
Database: Oracle 10g
IDE: JDeveloper 11.1.2.2.0
JDBC Driver: Oracle ojdbc6.jar
I connect successfully to the database through JDeveloper. There I see many folders listed, e.g. Tables, Views, Indexes, XML Schemas, XML DB Repository, and others. My problem is that when I try to save a large schema file (that I already validated on my local machine) that is roughly more than 300 lines, then JDeveloper is unable to save the file. It saves only very small files that are about 100 lines or less. The error message simply is: "Unable to save XML Schema blah.filename@local (Error saving XML Schema).
I tried to do it in Oracle SQL Developer too, but got the same error. Can someone please help me understand this problem and how to fix it? Do I need to specify some settings in JDeveloper or SQL Developer? Thanks a lot in advance.

Using OEPE as a database development environment
Howdy. I've installed OEPE (for Gallileo) and it seems to work pretty well for stuff like browsing my database object tree, viewing the contents of packages, etc. However, I'm a bit stymied when it comes to trying to actually use it to develop PL/SQL code, because it won't tell me when I've made an error. For example, I can create new sql file called CTestPackage_h.sql, and type into it a package header like so:
CREATE OR REPLACE PACKAGE cTestPackage AS
procedure test_me(
temp FOO NUMBER
END cTestPackage;
There's a syntax error there ("FOO" instead of "IN", "OUT", etc), but when I select and run it, my SQL Results tab says "Succeeded", along with the cryptic "Action Type" of "NLS missing message: OperationCommand_action_exeucte in: org.eclipse.datatools.sqltools.result.PluginResources". Likewise, the status tab says this, with no mention of any compiler errors:
(0 rows affected)
Elapsed Time: 0 hr, 0 min, 0 sec, 0 ms.
When I then refresh my package tree, CTESTPACKAGE appears, but there's nothing under it, and the context menu has a "Show Error" item that displays the real syntax error that occurred ("ERROR at line 4: PLS-00103: Encountered the symbol "NUMBER" when expecting one of the following: := . ) , @ % default character The symbol ":=" was substituted for "NUMBER" to continue. ").
When I right click the package node and choose "Open" it shows the text I entered, and shows "INVALID" on the status line of the details tab. When I right click and click "Compile", it says "Successfully compiled object "IVARLEY"."CTESTPACKAGE". But, it's still invalid, so that's not exactly true.
Is this the intended behavior? If so, I think it's pretty much unusable - every time I made a change to my PL/SQL package code and execute it, I have to refresh my tree, and then right click my package node to see if there were any errors? I'd much rather see my errors immediately. At the very least I'd like to see the "warning: procedure created with compilation errors" message, so that at least I'd know to go check for errors (though, ideally, seeing the actual errors immediately would be even better).
It gets even more confusing, though. When I right click the (invalid) CTESTPACKAGE node in my Data Source Explorer, and click "Edit", it opens it up in a new SQL window, which shows the text I'd entered (minus the trailing "/"). Running it from there does show a status of "Failed", but not because of the invalid syntax - the error message is "ORA_00900: invalid SQL statement", and persists even if I fix the syntax error (change "FOO" to "IN").
So, am I doing something wrong, or is this plugin not really intended for writing PL/SQL code?I'm looking for the same thing. Thanks for the "show error" tip -- that gets me slightly closer to having a usable environment in Eclipse. I also use the jOra plugin for eclipse. That worked great in earlier version of eclipse, but is a little buggy in galileo.
