Disadvantages of Normalization

Dear Friends,

We allready know Normalization is the process to optimize the storage and increase the performance of system by eliminating redundancy from database.



But there is also circumstances when Normalization can reduce database performance.Due to Joins-Jonis-Joins system makes complex to select a simple record-set.

A normalized database requires much more CPU, memory

and I/O to process transactions and database queries than does a normalization database.

  6. Howdy just wanted to give you a quick heads up.
    The words in your post seem to be running off the screen in Opera.
    I'm not sure if this is a format issue or something to do with web browser compatibility but I figured I'd post to let you know.
    The layout look great though! Hope you get the problem solved soon. Cheers

  7. Howdy would you mind stating which blog platform you're working with?

    I'm going to start my own blog in the near future

    The reason I ask is because your design seems different then most blogs and I'm looking for something unique.
    P.S Sorry for being off-topic but I had to ask!

What to do when facing errors on mongoDB “aborting after fassert() failure”

I like errors, in mongoDB this is the first error I faced and luckily many times. This error i faced during restoring name-space on local and restarting db system. I am still searching the exact root cause of this issue but i am able to resolve the current problem through below steps.

Thanks for reading, 
Please comment your experience if you faced and also share knowledge if you have better steps to resolve...
