I am using Oracle SQL Developer version 21.4.2.018.1706-x64 and I can't find the tool Data Generator.
I know that in older versions of SQL Developer it was in the Tools tab but in my version it's not... (like you can see on the picture)
In older versions the tools tab is like this:
If you know where it is, I will be very grateful.
Thank you for your time
Those are two different tools, PL/SQL Developer from Allround Automations is NOT Oracle SQL Developer.
Different products, different companies, even different user audiences. One's free, one's not. So they're similar in many ways, but not in many more.

I want to create table automatically using new table option in oracle SQL developer,but that option is disabled in my tool.
Can any one please help me out in this issue.
Please find the below image highlighted with red mark for your better understanding.
Thanks in advance.
To quote Jeff Smitth:
SQL Developer is built by Oracle, for Oracle. It’s the database IDE.
...
But, SQL Developer is also ... a 3rd party database migration platform.
...
Since we support migrations from these other database platforms, wouldn’t it be neat if SQL Developer could connect and query those 3rd party databases too? Surprise, surprise – that’s exactly what we DO do today.
What ‘Support’ means
You can connect to, browse, and query (SELECTs only) SQL Server, DB2, Access, MySQL, and Teradata.
What ‘Support’ does NOT mean
providing debuggers
delivering database administration features
write access to the database
Sound a little harsh or spartan? Going much further in any of these areas would just open a big ole can of worms, and we’re committed to providing an optimal experience for the Oracle database. But, since we already support these limited features, there’s no real reason to hide it.
That post is from 2012, but as far as I'm aware is still mostly true.
Since creating tables would count as write access and a DBA feature, it isn't a matter of enabling the option for your MySQL database, it isn't supported. This is an area of functionality that only applies to Oracle databases. (Even though Oracle Corp. owns MySQL... this means the Oracle RDBMS).
I am looking for a replacement our Foxpro application. Microsoft Visual FoxPro is a Boeing non standard software application. Microsoft has not released a new version since 2007 and has announced it will no longer be supporting the software. The department started using FoxPro software in the early 1990's and has built several tools used to perform our contractual SOW activities. FoxPro software is unique and no one tool exists that has the same capabilities. With the rollout of WIN7, we were required to purchase licenses last year to update the software to the 2007 version of Visual FoxPro. The previous 2003 version of Visual FoxPro is incompatible with WIN7. Since Microsoft is longer supporting the software it is only a matter of time before Visual FoxPro will be incompatible with a later operating system update.
Any ideas on of an application or a group of applications that can handle the capabilities listed below?
Open and alter numerous data tables at once
Process Word Documents to determine alteration made from master
copies
Allow coding for flexible data manipulation
Process and manipulate flat and excel files
Import Word Documents, excel spreadsheets, and flat files into tables
Hard code relationships between tables
Allow user and administrative privileges
Flexible data integration with other systems
As one of possible alternatives, I can recommend our software product: DBF Commander Professional. This is not an IDE as VFP, but it is supported now (up to Win 8.1), and I think it may be useful for you:
Open and alter numerous data tables at once - Supported.
Process Word Documents to determine alteration made from master copies - Not supported.
Allow coding for flexible data manipulation - SQL queries execution support.
Process and manipulate flat and excel files - Export to Excel supported, export/import from CSV supported.
Import Word Documents, excel spreadsheets, and flat files into tables - Not supported.
Hard code relationships between tables - Not supported.
Allow user and administrative privileges - Not supported.
Flexible data integration with other systems - Export to a database, Import from a database, etc.
Most of your requirements are not things that Visual FoxPro helps you with. Things like Process Word Documents to determine alteration made from master copies are very likely done by way of a COM bridge to Microsoft Office, and it's Word itself which handles the change rather than the vfp runtime.
Assuming that tight integration with Microsoft Office is something you're not considering to change, your best options are the two paths Microsoft offers:
Option 1. Microsoft Access
If you're installing your final tool on desktop that already have a license for Microsoft Office, don't have a team of OOP-savvy developers, and want a WYSIWYG data-management system that couples with office documents, Access is exactly what you want. If you want real security you may need to jump through a few hoops and possibly pick up a SQL Server license, but it's a product niche that overlaps very well with FoxPro and isn't going anywhere anytime soon.
Be aware if you go this path that Microsoft is transitioning Office to have a Software-as-a-Service bias, which may be either detrimental or advantageous depending on the actual needs of your customers and your company's various requirements and policies.
Option 2. Visual Studio
If you're a team of actual software developers with MSDN subscriptions or Visual Studio licenses, using .NET lets you hit all of your requirements plus more, although a more significant amount of training will be required. Visual Studio Tools for Office also lets you inspect and manipulate office documents without launching the final executables, which may grant you a significant speed advantage.
Note that the above are not by any way the only options, nor are they even exclusive. For raw data handling, you'll likely want to migrate to either SQL Server or a F/OSS equivalent such as MaraDB or SQLite, all of which are more than a match for what FoxPro brought to the table for most practical applications.
(There are some instances where FoxPro may be faster than latter-generation relational databases, but there are also several where the relational DB's are significantly faster than FoxPro.)
While the UI that VFP lets you build will get more and more dated (though take a look at http://vfpx.codeplex.com/ for some nice ways to modernize), VFP itself is likely to work for a long, long time. It's built using Visual C++, the same language that Office is build in, and Office isn't going anywhere and is unlikely to be rewritten in its entirety.

Transfer your data to SQL Server and use Visual Studio to create the user interface. I am doing this now with my company's huge volume of Visual FoxPro data and applications. You, of course, will need a developer to develop the application. You could also contact EPS Software, they help companies with FoxPro to .NET conversions. They are the same people that produce CODE magazine. We are considering for the work on our project.

I'm developing a small application with C# in .NET and I want to have a small light weight database which does not use much resources.
Could you please list some of the best known light weight database softwares.
14/06/2016 Yep... still getting upvotes :-/
17/03/2014 I'm still receiving upvotes for this, be mindful of the date this was originally answered. Though the main three items listed are still entirely viable, the list will tend towards becoming stale. There are further database technologies available that are not listed.
You have a couple of immediately recognisable and free options:
SQL Server Express LocalDB
SQL Server Compact Edition
SQLite
The SQL Server Compact download comes with the ADO.NET provider that you will need to reference in code. The SQLite download might not have it so here is a link:
http://sqlite.phxsoftware.com/
All three use SQL, though likely with a few limitations / quirks. Management Studio works with Compact and LocalDB, whereas with SQLite you will need another UI tool such as SQLite Administrator:
http://sqliteadmin.orbmu2k.de/
There are NoSQL alternatives, such as:
Sterling
RavenDb
Personally I would avoid using MS Access in the face of other free options. You cannot go wrong with LocalDB, Compact, or SQLite. They are all lovely small databases that run relatively quickly in little RAM - personal preference as to the religious aspects about liking a Microsoft product I suppose :-)
I use Sterling for Windows Phone programming as it is built to use Isolated Storage. I have only seen articles on RavenDb, but I can tell you that it is a JSON based document storage framework.
Not to confuse the situation (go with SQLite, SQL Server Express LocalDB, or SQL Server Compact Edition), but there are other embedded / local databases out there, some are relational others are object-oriented:
Embedded Firebird
db4o
VistaDb
SharpHSQL
Berkeley DB
Eloquera
SiaqoDb
Not all of these are free. SQL / LINQ / in-proc support differs across them all. This list is just for curiosity.
There is now also Karvonite, however the code gallery link is broken. When it's live again I'll be looking into this one for WP7 development.
I'd recommend SQLite. We are using it for almost all of the apps we develop where I work.
It's small and compact. It does require a DLL to be in the app directory, but you don't have to have other software installed like Access or SQL Server. Also, as stated by danielkza below, "SQLite is public domain, so you don't have to worry at all about licensing." That can really make a big difference.
You can use System.Data.SQLite or csharp-sqlite to access it in a C# app using the same methods as that of SQL or OleDB.
You will also need an application to edit/manage the database. The best one in my opinion is SQLite Studio. Here are a couple more:
SQLite Admin
SQLite 2009 Pro (bottom of the page)
Update - 7/25/11 - More SQLite apps (question here on SO)
Here's more on SQLite:
SQLite on Wikipedia
Companies that use SQLite
Custom Functions:
As an addition, if you are looking in the SQLite Core Functions and don't see one you like, you can create your own custom functions. Here are a couple of examples:
From SOAnoter example
Firebird embedded can be a good choice
The embedded version is an amazing variation of the server. It is a
fully featured Firebird server packed in just a few files. It is very
easy to deploy, since there is no need to install the server.
There is some very good dot net drivers
SQL Server Compact if you want to use the official microsoft solution. This has the advantage of being able to use replication with SQL server if you need that sort of thing.
SQLite if you want to somthing very simple small and free. This is what android uses for it's internal databases so it is very well supported and there are very good .NET bindings available.
One distinct advantage of SQLite is that it is cross-platform. So if you wanted to port your application to Mono.NET then you wouldn't have any modifications to make to the database implementation.
I do not like MS Access for this solution but a lot of people have included it in their answer. It is limited due to the proprietary format and platform dependence. It does have it's advantages though. You can manipulate data easily if you have a copy of MS Access, you can build queries graphically and create macros. You can easily integrate it with the rest of MS Office.
Out of all these SQLite would be my recommendation due to it being so compact, well documented and supported by a growing army of fellow developers regardless of platform.
EDIT
I realized that there is another option that everybody here forgot to mention
So long as you don't need relational tables you could use CSV file read as a dataset via ADO.NET. (More of a lulz suggestion than anything else but would be suitable in some cases and doesn't require additional libraries for a MS deployment.
If you are building a project with .NET 4.0.2 or greater and want embedded database support, consider SQL Server Express LocalDB.
It's a relatively new addition to the Express family that features a smaller installation footprint and reduced management overhead (when compared to other editions of Express), yet it maintains the programmability aspects of SQL Server. That is, unlike Compact Edition, LocalDB does not require the installation of a separate ADO.NET provider to communicate with SQL.
See the following for more details:
SQL Express v LocalDB v SQL Compact Edition (MSDN Blogs)
SQL LocalDB vs SQL Server CE (Stack Overflow)
what about http://en.wikipedia.org/wiki/NoSQL_(RDBMS) ?
in particular MongoDB for .Net
http://www.mongodb.org/display/DOCS/Home
You could use Sql Server Express Edition as its free and is equally powerful until and unless you want functionality like mirroring etc. Have a look at this.
I've used db4o with success.
File based, large community, simple to use.
http://www.db4o.com/
Licensing Details
Free General Public License db4o is licensed under the GPL by default.
The GPL license is ideal if you plan to use db4o in house or you plan
to develop and distribute your own derivative work as free software
under the GPL as well.
Commercial License A commercial license is required if you want to
embed db4o in a commercial non-GPL product. Commercial licensees gain
access to premium services and support.
An alternative that hasn't been mentioned if you don't require it to be a free database is VistaDB. It's all managed code, provides tons of features for an embedded database, and offers pretty good performance. A pretty good bridge between SQL CE and SQL Server Express since the majority of your VistaDB stored procedures will run without modification in SQL Server Express. I've been pretty pleased with customer service at this point as well. I've been using it at work. No services to start. An empty DB is around 1MB and the DLL is pretty lightweight too. Has ADO.NET providers and such things. I liked it a good bit.
VistaDB
SQL server Compact Edition best as it is free and Light in Size and integrates Well
SQL Server Express or MS Access

I am looking for some embedded databases. SQLite has some issues with the GUI. What about FireBird? How active is it's mailing list and forums? Does it follow all the rules of ANSI SQL? Is it suitable for production?
Is Firebird still alive? Are you kidding? It is only few weeks since Firebird 2.5 has been launched. We use it in our commercial products both ways, as a client server and as an embedded solution. We found it stable, powerfull and SQL compliant. Comparing with MSSQL there are two significant advantages.
Firebird is free;
Firebird is cross-platform.
I come from a primarily microsoft based background and typically work in C#, asp.net and sql server. I recently started working with firebird for one of my clients. I am enjoying working with it and I am using a tool called databaseworkbench for gui administration right now. I also here that IbExpert is a good gui admin tool. I plan to try it out and there are many others. I actually did not care much for the FlameRobin tool at all but that's just my personal opinion.
In my opinion if firebird shipped with a great built-in gui admin tool it would be much more popular. People struggle to figure out which gui admin tool to use and the gui admin tool you choose highly controls how you perceive firebird as a database because different gui admin tools offer different features and functionality. So far so good though here. The client I am working for right now has about 800 companies running the firebird db as a backend successfully.
Going to Firebird web site and checking their news, releases, and bigfix list will give you an idea how active it is. I am very pleased with Firebird and I can recommend it without blinking.
Sure. firebird is alive with new featurea.
I'm using it on production for long time and big tables
dbvisualizer works pretty well with firebird.
I have found firebird to be pretty reliable. However, there are some gotchas.
Eg,
Select first 10 * from table_a;
instead of
select * from table_a limit 10;
Using an orm to talk to db usually takes care of these differences.
I think, Firebird Development Studio from SQLLY is close to something called IDE for Firebird RDBMS (regardless of the bugs that I encountered while using it), I haven't found other tools that has a refactoring feature that very helpful at development stage.
The BI platform Pentaho 1.7 used to have an extension that allowed applications to be accessed from iPhone:
http://www.pentaho.com/launch/iPhone
Is it still maintained?
If so, is it available in the Community Edition?
Their iPhone/iPad code is still maintained as far as I can tell, but only available in the Enterprise Edition.
That said, there is an Open Source Android app available here:
http://code.google.com/p/pentaho-android/
Your mileage may vary, some restrictions apply, etc, etc. =p
