We have grown from a small time of 2-3 developers to about 30 developers very quickly. We supposedly never needed Source Control, or Db Monitoring or Schema diagrams.
Now we see more and more terrible code being moved to the Production. Is there an off the shelf product for oracle that will help manage version control and deployment management from Test, to UAT, to Prod?
Also nice to have would be Schema diagrams, Documentation Tools, some amount of performance profiling capabilities. But primarily would like to a tool to manage code source control and Migration for oracle scripts, DDL, DMLs etc.
I srongly recommend getting Oracle'e SQL Developer. This integrates with Subversion, provides an overview of the entire database, including procedures, schema changes and so on. This will make your life easier.
have you considered SVN for your source control and management of scripts, DDLs and etc? Our ORACLE DBAs use it here and they swear by it.
I know I am very late to this party, however, I wanted to draw your attention to our product, dbMaestro TeamWork for Oracle, which provides exactly the functionality required here. We offer the functionality equivalent to source control tools for Oracle artifacts. Many companies use SCM by proxy (as suggested above by northpole, re using SVN), our solution is "in touch' with the database as required by Reuben on the original post. To read more please visit our site at http://www.dbmaestro.com or e-mail us at info#go-esi.com.
Disclosure - My company represents this product in the US.
TOAD (by Quest Software) is fantastic and includes most of what you want including source control.

Actually we have been asked not to use open source databsae. So, Now I have to use proprietary database. Now my doubt is What is best equivalent Proprietary database of postgresql and also it should be cost effective.
Please give some suggestion
The decision maker here has some weird ideas - specifically not open source, but they don't care what you use so long as you don't have the source code? That's nuts.
Maybe they don't understand open source licenses and are confusing GPLv3 with the simple BSD/MIT-like license PostgreSQL is under? They might have images of "open source" meaning some kind of terrible viral license that takes all their patents and forces them to open source all code that it touches (which isn't true even of GPLv3, btw). Try sending them the wikipedia article, FreeBSD's article on the license, and that of OpenBSD. They should also read the OSI FAQ. If they're still determined to waste their money after reading that and doing a little basic research, there's no saving them.
In that case, I would take the PostgreSQL source code, rename it "ProprietaryDB", whack on a restrictive all-rights-reserved license, and sell it to them for $5000/server for a perpetual license. PostgreSQL is under a BSD-like license and you're permitted to do this so long as you don't delete the copyrights from the sources or claim you wrote it. I'll gladly do this for you for as little as $4000/server, a real bargain ;-)
More seriously, there are quite a few proprietary PostgreSQL forks already, notably:
ParAccel
Greenplum Database
EnterpriseDB Postgres Plus Advanced Server
... and Amazon will sell you a ParAccel based DB as a service, Redshift, too.
Amazon RDS PostgreSQL is arguably a closed source fork too, though it tracks mainline PostgreSQL closely and there doesn't seem to be much real difference if any.

I am developing with Delphi XE2.
I am planning a software for primary and secondary school. This school have 1,500 students. The database model is relational and we plan to keep the whole history of each student as the years move on. (well at some point it will be archived, but mostly all the relationships will be maintained for a good time)
I used to write Delphi apps using DBISAM V4 from Elevate Software. I hold a licence of it, so it is still a possibility for use it.
However I had contact with many companies using Firebird recently, some using Postgres and many websites with MySQL.
I don`t see a need to go paid databases, since this type of customer is sensitive in investment. So any database that is free for such use, plus the option of keep using DBISAM. I like it but it is getting old.
I prefer to put the business logic on the software, not in the database, so no need to intricate logic or procedures on the database side.
My questions is: What I need to consider to choose the correct database?
This Wiki post can help you. Besides that, you have to decide for using OLE-DB, ODBC or DBX as middleware technology. Depending on which one you will find or not support for Delphi.
Another criteria include know-how on the database options and rectrictions/requirements on security and scalability.
However, no matter what DBMS you choose, my best advice for you is to isolate the access to it in a dedicated service layer so most of your application won't be directly dependent of it.
In your place I would model the application in terms of domain classes and would invest in a persistence layer. If you have to go for another DBMS in the future, most of you code will be preserved.
DBISAM will work here, and you can even write a webservice in Delphi, to provide access to tablets and such. You need to start thinking about the things that really matter here, such as what platform the users are on, how many users total, how many users will be using the database simultaneously (average and peak), how many rows are kept per student, how many add/delete/updated rows daily, etc.. DBISAM has limited SQL. It does a lot, but not everything that you can do in other databases. Their newer product, ElevateDB, addresses most shortfalls, including Unicode.

I mean a php online script that connects to Oracle? Or should I use navicat? Is navicat that good? Any other alternative? I secretly hope that I will not be forced to use command line interface for a product that costs $40k (Well I am using the Express Edition. But anyway).
Check out Oracle SQL Developer. It's free, and it is a fully featured IDE. Find out more.
I use PLSQL Developer. It's not online, but it beats command line interfaces. :)
As others have posted, I use SQL Developer for my IDE. However, if you are looking for a fully functional web interface like PHPMyAdmin, check out Oracle's Application Express (Apex).
It's free, and although it's meant as a rapid web development tool, it has great tools to manage your schema, tables, and other objects.
In addition to SQL Developer and PL/SQL Developer, you could use TOAD (Tool for Oracle Application Developers). It has both a paid for version and a free version.
In my experience the free version is easy to use and powerful enough for most users.

I've just started looking at gemfire. I'm really impressed actually. I'm a little confused by its licensing, there seems to be some indication that some of it is open source? Does anyone have any clear idea? I'm loathed to talk to their sales people.
If not, are there any open source alternatives? I can think of a few technologies which offer the same features but not as a whole.
Unfortunately there are no open-source in-memory data grid solutions. You can check alternative distributed caches like Coherence from Oracle, eXtream scale from IBM, XAP from GigaSpace.
Quick search can bring you to following solutions:
Hazelcast - In-Memory Data Grid
Cacheonix - In-Memory Data Grid
You can try it. Most probably it is young generation of IMDG and they have not full functionality. But it's free.
BTW: what functionality you want to use? some times IMDG it's just a fix for bad architecture.
This question was first posed way back in 2011, but it still seems pertinent, as Gemfire is still referenced in the latest suite of Spring demos on the Spring.io Pivotal site:
"As of the 1.2.0 release, this project, formerly known as Spring GemFire, has been renamed to Spring Data GemFire to reflect that it is now a component of the Spring Data project."
So to use Spring Data, or to at least follow along with the latest "Yummy Noodle Bar" Spring Tutorial suite, it is sort of implied that you need to use the proprietary "Spring Data Gemfire" product for the Order Status solution component (the other two components of the demo being MongoDb for the Menu Item data, and a relational DB like Postgres or MySQL with JPA for the Orders data).
I did some more recent searches and in addition to Hazelcast, I was really only able to come up with one other open source solution which might also fit the bill as a Gemfire alternative :
http://www.gridgain.org/
As for me, I think I'll probably start with Hazelcast and see how that pans out.
In general, I should say that I'm a little disappointed at Pivotal for sneaking a commercial product into their otherwise open source tutorial. It's one thing to lead people to Gemfire with an open source entry level version of the product, but to force developers to sign up for a free trial version of a commercial product that they really have no business purchasing for their development platform in the first place kind of sucks IMHO. Please correct me if I am missing something here.

This post from SqlBatman describes a situation similar to my current client and, in reality, indicative of many companies that rely on tons of reports which have been shifted to over-night processing because of their performance impact.
How do I get started using Analysis Services in general and OLAP Cubes in particular to help my clients?
I really like Analysis Services Step by Step to get up to speed on all that SSAS can do.
In short, SSAS gives you quick access to pre-aggregated data. The real power of OLAP is not in being able to generate reports quickly, though; it's in being able to interact with the data. Slicing, dicing, drilling down, up, and through. It's a dataphile's dream.
That being said, if you just want to get static reports out of this, or you want to build out cubes, you really, really, really need to get up to speed on data warehousing. Grab a copy of The Data Warehouse Lifecycle Toolkit for this. Kimball's the authority on this, especially if you'd like to use SSAS on top of it.
The warehouse is the cake, the cube is the icing. Bake the cake, first, and the cube just gets put on top to make it that much better.
Cheers,
Eric
