Often, we are hearing a frequent new about software down due to financial break down in US.
I got some information on recent happenings in software field.
HP Layoffs
HP 24000 Lay-offs - After acquiring EDS, HP is planning to reduce their work force and they planned to take out 24000+ employees from their company. It includes both higher level and lower level people.
Satyam 4500 Job cuts :
Due to lehman brothers closure, Satyam computers has just started giving pink slips to its employees, could potentially downsize its workforce by a whopping 4,500 employees. Recently, satyam head have informed their employees not to be panic and advising his people to work hard.
Wipro technologies started giving pink slips:
Wipro technologies has put about 4-5% of its workforce, about 2,400-3,000 employees, under the scanner for non-performance.
This is the cycle and everyone has to sustain this problem. If you see the past 10 years record of IT industry it got changed in 2-3 times majorly in 2003. Satyam and Wipro are service based companies if their client is going to the depth of loss then why they bare the loss it is obvious that they will fired the employees.
The recent IT Lay offs is mainly due US Market slowdowns. And as everyone of us knows that the market is never stable. Who knows that though it is down now, it may grow at a remarkable height.
This is once again the firing season for IT. Satyam Computers has just started giving pink slips to its employees and around 4,500 of its employees are scheduled to get the boot.
wipro firing
Wipro Technologies has put about 4-5% of its workforce or about 2,400-3,000 employees, under the scanner for non-performance.
tcs firing
In February, TCS had given pink slips to 500 non-performers.
IBM firing
IBM India also asked about 700 employees to leave, citing non-performance.
patani firing
In July, Patni computer systems fired 400 employees.
If the going is tough for these bigwigs, what about those in the lower rung? Mid tier companies are also doling out pink slips in all generosity! Hexaware has reportedly booted out 500 people and this does not include the 130 employees to be laid off due to the shut down of its office in Gurgaon. Ramco Systems laid off 142 employees.
Not true news on infy firing.

SQL Server Interview questions - Part 1
What is the significance of NULL value and why should we avoid permitting null values?
Null means no entry has been made. It implies that the value is either unknown or undefined.We should avoid permitting null values because Column with NULL values can't have PRIMARY KEY constraints. Certain calculations can be inaccurate if NULL columns are involved.
What is SQL whats its uses and its component ?
The Structured Query Language (SQL) is foundation for all relational database systems. Most of the large-scale databases use the SQL to define all user and administrator interactions. It enable us to retrieve the data from based on our exact requirement. We will be given a flexibility to store the data in our own format.
The DML component of SQL comprises four basic statements:
* SELECT to get rows from tables
* UPDATE to update the rows of tables
* DELETE to remove rows from tables
* INSERT to add new rows to tables
What is DTS in SQL Server ?
Data Transformation Services is used to transfer the data from one source to our required destination. Considering am having some data in sql server and I need to transfer the data to Excel destination. Its highly possible with dialogue based tool called Data Transformation services. More customization can be achieved using SSIS. A specialized tool used to do such migration works.
What is the difference between SQL and Pl/Sql ?
Straight forward. SQL is a single statement to finish up our work.Considering, I need some data from a particular table. “Select * from table” will fetch the necessary information. Where as I need to do some row by row processing. In that case, we need to go for Procedural Logic / SQL.
What is the significance of NULL value and why should we avoid permitting null values?
Null means no entry has been made. It implies that the value is either unknown or undefined.We should avoid permitting null values because Column with NULL values can't have PRIMARY KEY constraints. Certain calculations can be inaccurate if NULL columns are involved.
Difference between primary key and Unique key?
Both constraints will share a common property called uniqueness. The data in the column should be unique. The basic difference is,
· Primary key won’t allow null value. Whereas, unique key will accept null value but only one null value.
· On creating primary key, it will automatically format the data inturn creates clustered index on the table. Whereas, this characteristics is not associated with unique key.
· Only one primary key can be created for the table. Any number of Unique key can be created for the table.

SQL Server Interview Question - Part 2
What is normalization?
Normalization is the basic concept used in designing a database. Its nothing but, an advise given to the database to have minimal repetition of data, highly structured, highly secured, easy to retrieve. In high level definition, the Process of organizing data into tables is referred to as normalization.
What is a stored procedure:
Stored procedures are precompiled T-SQL statements combined to perform a single task of several tasks. Its basically like a Macro so when you invoke the Stored procedure, you actually run a set of statements. As, its precompiled statement, execution of Stored procedure is compatatively high when compared to an ordinary T-SQL statement.
What is the difference between UNION ALL Statement and UNION ?
The main difference between UNION ALL statement and UNION is UNION All statement is much faster than UNION,the reason behind this is that because UNION ALL statement does not look for duplicate rows, but on the other hand UNION statement does look for duplicate rows, whether or not they exist.
Example for Stored Procedure?
They are three kinds of stored procedures,1.System stored procedure – Start with sp_2. User defined stored procedure – SP created by the user.3. Extended stored procedure – SP used to invoke a process in the external systems.Example for system stored proceduresp_helpdb - Database and its propertiessp_who2 – Gives details about the current user connected to your system. sp_renamedb – Enable you to rename your database
What is a trigger?
Triggers are precompiled statements similar to Stored Procedure. It will automatically invoke for a particular operation. Triggers are basically used to implement business rules.
What is a view?
If we have several tables in a db and we want to view only specific columns from specific tables we can go for views. It would also suffice the needs of security some times allowing specfic users to see only specific columns based on the permission that we can configure on the view. Views also reduce the effort that is required for writing queries to access specific columns every time.
What is an Index?
When queries are run against a db, an index on that db basically helps in the way the data is sorted to process the query for faster and data retrievals are much faster when we have an index.
What are the types of indexes available with SQL Server?
There are basically two types of indexes that we use with the SQL ServerClustered -
1. It will format the entire table, inturn physically sort the table.
2. Only one clustered index can be created for a table.
3. Data will be located in the leaf level.
4. By default, primary key will create clustered index on the table.
Non-Clustered Index
1. It wont touch the structure of the table.
2. It forms an index table as reference to the exact data.
3. A reference to the data will be located in the leaf level.
4. For a table, we can create 249 non clustered index.
Happy Learning!!!

SQL Interview question
Extent Vs Page?
Pages are low level unit to store the exact data in sql server. Basically, the data will be stored in the mdf, ldf, ndf files. Inturn, pages are logical units available in sql server.The size of the page is 8KB.
Eight consecutive pages will form an extent 8 * 8KB = 64KB.
Thus I/O level operation will be happening at pages level.The pages will hold a template information at the start of each page (header of the page).
They are,
1. page number,
2. page type,
3. the amount of free space on the page,
4. the allocation unit ID of the object that owns the page.
Extents will be classifed into two types,
1. Uniform extents
2. Mixed extents
Uniform Extents:It occupied or used by a single object. Inturn, a single object will hold the entire 8 pages.Mixed
Extents:Mulitple objects will use the same extent. SQL Server will allow a max of eight objects to use a shared extent.
Property of SQL Server :Initally if an object is created, sql server will allocate the object to the mixed extent and once if the size reaches 8 pages and more... immediately, a new uniform extent will be provided for that particular object.
Herecomes, our fragmentation and reindexing concepts.

This was unavoidable!
I have been now 14+ years in this industry, have gone through the .com bust even. What I can observe in my entire tenure, these entities which are laying off people, were intaking people in huge number anticipating that they will get new projects!
One new identity evolved as "Benchers"!
My question was why?
Are the non-benchers are doing really putting their full time in work?
Was the management plan such to utilize the full extent of workforce these entities already had?
I have been supervised many people, from fresher to experience. I can conclude now, people have a high expectation on pay packs, onsite visit, very fast growth, but, what about performance?
The moral of each and every individual who are in this industry, seems down, but, I ask them, have you every given 100% of yours? Be it from lower level to management level?
TO me, this was unavoidable, unrealistic number of hiring, faulty plans from personal level to instituation level has contributed towards this mess.
Thanks Venkat for sharing all the information related to Pink Slip..Can you advice on what should a person do in such a condition?
Hi Neha,
This issuance of Pink slip is not the one happening all of a sudden. People would have been given sufficient breathing time say a month or two. No IT companies ask you to stop coming office from the next day.. They too are professionals.
In such a situation we should equip ourself with the current market requirement. Always remember that a door will be open for us to enter. Keep yourself updated with the market demand and get a switch over at the right time to upgrade ur career in style
HI,
I too in IT industy from 4 + Yrs,it is the bad policy of companies and more expectation from individual.companies hired too many resources and keep them on bench,and now doing layoffs.companies from starting must keep good resource utilization ,instead of just hiring and firing.
