  3. What is SQL Server? It is software which is run on the Windows Server and allows its users to both stores and fetch data in a database using the TSQL language. It is rare that end users have to directly interact with SQL Server, but they can only access data in the form of reports, web pages, and some other applications. The Database Administrators make use of the SQL Server Management Studio for looking after the software. www.JanBaskTraining.com Copyright © JanBask Training. All rights reserved

  5. How to become a SQL Consultant or a DBA?

  6. Skills Required To begin with, you will need a reasonably modern PC/ laptop, recent Windows version, and enough space for the installation of the basic databases. The foremost requirement for learning is a proper place to learn. For beginners, you may start with a basic and free Developer edition of SQL Server on the virtualization platform of your choice. You may also use Azure hosted virtual machines. www.JanBaskTraining.com Copyright © JanBask Training. All rights reserved

  7. DBA For A Beginner Training Error:  Installation of SQL Server and application of the latest service pack in addition to setting up jobs and email notifications.  Creation and management of users, logins, and other roles at the database level.  Should have thorough knowledge about GRANT, REVOKE and DENY.  Creation and modification of tables, views, functions, etc. www.JanBaskTraining.com Copyright © JanBask Training.

  8. Importance of Training and Certifications  It is not necessary that you have to take training for the above as many successful DBAs have taken up skills by themselves reading from books or online videos at their own pace and availability.  If this is not your cup of tea and you need to be coached, then you may prefer short courses which focus on SQL Server administration.  It is quite obvious that you will not be able to become a master in 5 days, but the course will put you on the right track as it will act as a first step in the learning curve.  If you are already employed the high course fee is shared by the employers. www.JanBaskTraining.com Copyright © JanBask Training.

  9. Estimating Error Rates IV Bootstrap  Works well with small data sets  Samples the given training tuples uniformly with replacement  i.e., each time a tuple is selected, it is equally likely to be selected again and re-added to the training set Several boostrap methods, and a common one is .632 boostrap  Suppose we are given a data set of d tuples. The data set is sampled d times, with replacement, resulting in a training set of d samples. The data tuples that did not make it into the training set end up forming the test set. About 63.2% of the original data will end up in the bootstrap, and the remaining 36.8% will form the test set (since (1 – 1/d)d ≈ e-1 = 0.368)  Repeat the sampling procedue k times, overall accuracy of the model: k   . 0   ( ) . 0 ( 632 ( ) 368 ( ) ) acc M acc M acc M _ _ i test set i train set  1 i www.JanBaskTraining.com Copyright © JanBask Training.

  10. Conclusion There is a lot of scope for a career in SQL as it finds use in multiple domains. You have to acquire suitable skills and certifications to be able to enter the job market. As most organizations hire only one DBA, so the choice is a vital one for them. It is a known trend that mostly such vacancies are filled from the existing staff members who were working on different roles but have acquired the DBA skills along with their career. www.JanBaskTraining.com Copyright © JanBask Training.
