schema in Oracle - sql

I want to know is there any software design the schema of oracle database?I mean if you work with Microsoft Sql U can easily design your database ,see the relation ,all tables and their fields,I want to know is there any software do same work in oracle.
I already try to find it in oracle Developer but nothing found!

Take a look at Oracle SQLDeveloper, I think it provides such functionality.

Not free, but PowerDesigner, Embarcadero, ERWin... can be used for that.

Toad also does this Toad for Oracle - Freeware

Redgate SQL Prompt equivalent for PostgreSQL database

I'm starting at a new company after coming from a previous role where I could rely on Redgate's SQL Prompt with a MySQL environment. I'm now working with a Postgresql environment (SQL Workbench/J) and was wondering if anyone had come across any similar programs for Postgresql to make the query writing a bit less tedious and time intensive.
I'm aware of the CNTRL + Space option for suggesting columns/tables, hoping for something that automatically prompts.
Thanks!
You can use the dbForge Studio for PostgreSQL software to meet your needs, and this will help you to use this software in accordance with what is in the SQL Prompt program.
I hope the explanation I gave was useful to you.
A full-featured GUI tool for PostgreSQL is pgAdmin.
Among many other useful features, it has a query tool with code completion and suggestion.

RedGate SQL Search Equivalent for Oracle?

I have recently started using Oracle. In last few Years I had used SQL server and used a tool called "RedGate SQL Search" and found
to be very useful while maintaining projects with huge database size.
I need an equivalent tool for Oracle , Anyone having any idea?
I suggest you try PL SQL Developer I have used it too much, I have used RedGate tools also too much, the tool I mentioned for Oracle Database has most of features of "Red Gate SQL Search" for Oracle and in some cases it has some different and better features.

PostgreSQL visual interface similar to phpMyAdmin?

I'd like to view and possibly edit tables for PostgreSQL visually like phpMyAdmin, where you can see the list of tables, and fields and individual rows for a table. Is there any utility that can do this?
Forgive me if this is actually possible in pgAdmin III, but I couldn't figure out any way to see tables visually in pgAdmin. I have PostgreSQL 8.4 (I actually didn't install it myself, it was installed by another piece of software that utilizes it)
phpPgAdmin might work for you, if you're already familiar with phpMyAdmin.
Please note that development of phpPgAdmin has moved to github per this notice but the SourceForge link above is for historical / documentation purposes.
But really there are dozens of tools that can do this.
I would also highly recommend Adminer - http://www.adminer.org/
It is much faster than phpMyAdmin, does less funky iframe stuff, and supports both MySQL and PostgreSQL.
pgAdmin 4 is a powerful and popular web-based database management tool for PostgreSQL - http://www.pgadmin.org/
Azure Data Studio with Postgres addin is the tool of choice to manage postgres databases for me. Check it out.

Can any one help me regarding the conversion of Oracle Scripts to SQL Server Scripts?

Is there any tool for conversion of Oracle Scripts to Sql server 2005 Scripts?If there please provide me the link.I had nearly 950 tables .Thanks in advance
If you still have the database running in Oracle, perhaps you could try using the Import features of SQL Server...see this shortish msdn article. You would just need to have the Oracle .Net data provider according to the page.
disclaimer: really, I have no idea if this would/could work...other than what I would expect that an Import tool could/should provide...

Good test database on Windows to play around with data retrieval operations in SQL?

I need a test database to practice joins and other kinds of data retrieval operations in SQL.
What's a good free test database and RDBMS system to use on Windows?
Every major RDBMS provider has some free edition. Those are full versions limited by database size and maximum memory usage.
Top players:
Sql Server Express
Oracle Express
IBM DB2 Express-C
Then, there is number of open source products:
PostgreSQL
Firebird
MySQL
SQLite (not really a RDBMS, but understands SQL and it can be used for your purposes. Also, very small and compact)
If this is not enough, check this Wikipedia article: Comparison of relational database management systems.
There's more than 50 RDBMS's listed and you'll probably find something that suits your needs.
SQL Server Express for one.
Sample databases (AdventureWorks) can be downloaded here.
You can use this link. The adventure works database is used as an example for numerous online and offline resources.
After which, download the SMSS Express to work on it.
If it's just for practising SQL you could install Access assuming you have an MS Office CD that includes it already.
Otherwise MySQL or SQL Server Express are probably your best bets.
I would recommend MySQL over SQL Server Express if your purpose is to practice SQL. The command line interface is all you need.
You can get online practice with verifying your queries on SQL Exercises
