Which is the best database to manipulate 100 million records which configures with c# win. form.

All the known databases - SQL or NoSQL - can easily handle a 100 million records. All of them has also binding to .NET (so to C#)...
You may map your request on that data, store only, OLAP, more read than write...

actually i am already working on sql but i am not sure that it can manage 100 million record. somebody suggested me oracle is oracle better than SQL.

I've worked with SQL had table with over 800 million rows - so no problem. The main factor is the usage. You have to find a good PK and as less as possible other indexes and FKs...
However if you aim to even higher you may look for some big-data database...

I have worked with 300 million rows in an Oracle database and yes it handles them well however... so will a SQL Server database.
What matters is how the indexes and partitions are set up on tables, as access to tables with this number of rows will be considerably affected by these decisions.
With 100+ million rows you are most likely going to need to partition tables.

Oracle because it has more security than SQL.

I'm not familiar with Oracle. Would you care to expand on that statement? What security features does Oracle provide that are missing from MS SQL?

What's funny but totally expected is that both Oracle and Microsoft claim that their database has the better security.
I'm of the opinion that the safer product is the one with the better DBA.
And since SQLServer is easier to run out of the box...

Really? Can you elaborate on that?

According to the Microsoft document "Maximum Capacity Specifications for SQL Server":
Rows per table: Limited by available storage
Database size: 524,272 terabytes
So unless each of your rows is going to exceed 5.36 gigabytes, you should be fine.

I've worked with a SQL database that had a single table with a few billion rows (Inventory type stuff). So, yea SQL can scale as far as you need it too.
Common sense is admitting there is cause and effect and that you can exert some control over what you understand.

and sir, is the searching good (fast).
|
|
|
|

Yup, never a problem. The table was indexed for the usage.

Does "Indexed" mean using primary key as filter or something else?

We work with both Oracle and SQL Server in those sort of volumes and I will reluctantly state that Oracle handles the volume better than SQL Server. However the reason may well be that for Oracle you generally need a dedicated DBA to drive the bastard. Also look into the comparative costs of purchase and support of the 2 systems, Oracle is substantially more expensive than SQL Server.
We have a rule of thumb that Oracle is used for enterprise apps and SQL Server for departmental apps.

I believe you're onto something there.

I wonder how much of that's a myth? For us it was a little bit cheaper actually.

But don't you have to pay something like 22% of the original cost every year in "maintenance charges"? Whereas, once you've bought SQL Server, you only have to pay if you want to upgrade.

You don't need to pay the maintenance fee. You can keep on using it as long as you want to. What you're missing out on is support and "windows update" aswell as upgrades.
And that support is of a wildly varying quality. If you call in the morning, someone with a very strong Indian accent called "Kevin" answers, and if he understands my problem, I won't understand his answer.
Anyway, if you have SQLServer you still have to pay for support and upgrades, don't you?
It's not an apple to apple comparison.
What you can see is that Oracle is trying to price themselves into smaller systems while MS is trying to gain grounds among larger systems. Because when you have a large server farm Oracle is considerably more expensive.

You have to pay for upgrades to a new version, or to a higher edition, and you have to pay if you want someone from Microsoft on the phone helping to diagnose a problem. However, service pack (which now seem to be a thing of the past) and cumulative updates are free.
Jörgen Andersson wrote: Oracle is trying to price themselves into smaller systems
I'd have thought that most small systems would be using the Express edition of SQL or Oracle, which is free.

Yes, but the express editions only use 1 GB of memory. It's good enough for CRUD, but very fast growing to small when you need to analyse data.
That's when the standard edition comes into play. That's competitively priced, in contrast to the Enterprice edition which is a class of its own.

I agree with them who said that both Microsoft SQL Server and Oracle can do so.
When you decide for one of it, note that Oracle is more complicated. SQL Server will handle many things for you automatically - like autoincrement values for keys, while with Oracle you have to setup a sequence, and a trigger for linking your table to the sequence on the appropriate events. In .Net languages, an empty string is not null, but for Oracle there is no difference - and meanwhile I say: Oracle is right from the view point of requirements. But it may cause problems for the programmer. And there are several more such oddities.

I think you'll find that a lot of people disagree with you on that one - including the ANSI SQL 1992 standard.
Of course, Oracle's weird behaviour pre-dates the standard, and can't be changed for backwards-compatibility reasons.

Could be fixed with a compatibility setting, just like on SQLServer.
I believe they won't do it because it's one of the things that gives them an upper hand on performance.

I know that, and in the past I thought that string.Empty and null must be different.
But look at a process before software: a user fills in a paper form. For a question he does not provide an answer. Is that null ("'answer' is not set to an object"), or did he answer with "string.Empty"?
And exactly that's the point why I agree with Oracle, though it causes pain in programming (and providing compatibility to a "wrongly-designed" Microsoft SQL Server database where string.Empty was allowed but not null... Yes, I had to experience that, and coursed about Oracle (and still do), but here they are right: if a column accepts string.Empty, that's equivalent to accepting null.
