Object Oriented DBMS (OODBMS)


Please visit SQLVERSITY.COM for more details.

A database management system is said to be object oriented, if the data is stored in the form of objects.

The name itself says that Object Oriented(OO) + Database Management System(DBMS). That means, If we integrate the features of object oriented programming language like C++, Java, C# etc.. and database, the result will be object oriented database management system(OODBMS). It is also called as an object database management system (ODMS). It allows the developers to store the data or modify the data in the form of objects.

Ex: EyeDB, Versant etc..

SQL Server – Change Data Capture(CDC)

Please visit SQLVERSITY.COM for more details.

Thank you very much for reading my previous article Change Tracking (CT) and I hope you have enjoyed while reading the content of CT.

As I promised you guys, I am back with another awesome feature of SQL Server 2008 called ‘Change Data Capture (CDC)’.  As you all know that I am a lazy fellow and in this entire article I am going to call it as CDC for my convenience.

Microsoft has introduced this feature to overcome a small drawback in CT.

I hope you already got to know the drawback in CT. That is, we cannot get historical data in CT. That means, we can get the details of Primary key, DML (like I/D/U) changes which we have done to the table. But not entire modified data. By using CDC, we can retrieve historical changes also.

Here it goes……!!! (more…)
