    Note: Normally comparison is when the product is migrating from one version to other version.

    This much can convince the interviewer that you are clear about the differences. MSDE was always meant for trial purpose and non-critical projects.

    Workload governor sits between the client and the database engine and counts the number of connections per database instance. If Workload governor finds that the number of connections exceeds eight connections, it starts stalling the connections and slowing down the database engine.

    Note: It does not limit the number of connections but makes the connection request go slow. But it just makes the database engine go slow above eight connections. Following are some major differences between the two versions: PG The most significant change is the. Stored procedures, user-defined functions, triggers, aggregates, and user-defined types can now be written using your own favorite.

    NET language VB. NET, C , J etc. It was a separate installation for SQL Server Problem with image and text data types is that they assign the same amount of storage irrespective of what the actual data size is. This problem is solved using varbinary max which acts depending on amount of data. In addition, stored procedure invocation is enabled using the SOAP protocol.

    PG Asynchronous mechanism is introduced using server events. In Server event model the server posts an event to the SQL Broker service, later the client can come and retrieve the status by querying the broker. In data partitioning, you break a single database object such as a table or an index into multiple pieces. Now in one SQL connection, you can query and have multiple results set.

    You cannot access the sys object directly as in the older version we were accessing the master database.

    Note: Hyper threading is a technology developed by INTEL which creates two logical processors on a single physical hardware processor. AMO Analysis Management Objects to manage Analysis Services servers, data sources, cubes, dimensions, measures, and data mining models.

    NET Framework. Note: There is a question on this later see for execution context questions. Now the user owns schema.


    Note: Ok below are some GUI changes. Query analyzer is now replaced by query editor. Business Intelligence development studio will be used to create Business intelligence solutions. You do not have to really say all the above points during an interview. A sweet summary and you will rock. Q What are E-R diagrams? E-R diagram also termed as Entity-Relationship diagram shows the relationship between various tables in the database.

    Example: Tables Customer and Customer Addresses have a one to many relationship i. ER diagrams are drawn during the initial stages of a project to forecast how the database structure will shape up. There are three major relationship models: One-to-one Figure 1.

    Example: Every one customer can have multiple sales. So there exist one-to-many relationships between customer and sales table. One Asset can have multiple Maintenance. So Asset entity has one-to-many relationship between them as the ER model shows below. For instance: In a company, one employee can have many skills like Java , C etc. Given below is a sample of many-to-many relationship.

    One employee can have knowledge of multiple Technology.

    So in order to implement this, we have one more table Employee Technology which is linked to the primary key of Employee and Technology table. What are the Different Types of Normalization? Note: A regular. NET programmer working on projects often stumbles on this question, which is but obvious. The bad part is sometimes the interviewer can take this as a very basic question to be answered and it can be a turning point for the interview. So let's cram it. It is set of rules that have been established to aid in the design of tables that are meant to be connected through relationships.

    This set of rules is known as Normalization. Benefits of Normalizing your database include: Avoiding repetitive entries Preventing the need to restructure existing tables to accommodate new data Increased speed and flexibility of queries, sorts, and summaries Note: During an interview, people expect to answer a maximum of three normal forms and that's what is expected practically.

    Actually you can normalize database to fifth normal form. But believe this book, answering three normal forms will put you in a decent shape during an interview.

    The three normal forms as follows: First Normal Form For a table to be in first normal form, data must be broken up into the smallest units possible. In addition to breaking data up into the smallest meaningful values, tables in first normal form should not contain repetitions groups of fields.

    In order for these tables to be in First normal form, you have to modify the table structure as follows. Also note that the Customer Name is now broken down to first name and last name First normal form data should be broken down to the smallest unit. In other words, each non-key field should be a fact about all the fields in the primary key. In the above table of customer, city is not linked to any primary field.

    That takes our database to a second normal form. Third Normal Form A non-key field should not depend on another Non-key field. The field Total is dependent on Unit price and qty.

    Q What is Denormalization? Denormalization is the process of putting one fact in numerous places it is vice-versa of normalization.

    Only one valid reason exists for denormalizing a relational design - to enhance performance. The sacrifice to performance is that you increase redundancy in a database. Note: Whenever the interviewer is trying to go above the third normal form, there can be two reasons, ego or to fail you.

    Three normal forms are really enough, practically anything more than that is an overdose. This chapter I have not altered too much in this edition as new kid in the block, MVC has arrived.

    But I have still reworked on some answers and diagrams which where confusing in the previous edition. This is a major thing in sixth edition , a complete new chapter dedicated to MVC. I have added around 30 situational based questions in this chapter to do full justice for this chapter. This is one chapter I always thought I should work one. But for now I have kept the same questions and updated some answers which were not looking proper.

    Added some questions around WCF 4. Updated lot of questions around WPF. Not much changed in this and chapter as such but added some few more architectures and patterns like MVVM and repository pattern. In this chapter I have done major revamps and addition. Updated some old threading answers and added questions around TPL Task parallel libarary. XML chapter kept as it is. Some of the question I was not sure where I should put it like algorithms , questions around debug release , packaging etc.

    So this chapter will serve that purpose. I have started adding questions around algorithm's in this chapter. As usual salary card , sample resumes are my added flavors in the book. This is really a gift to my developer friends. I am sure my book will read by lot of fresher friends. So in case they want to learn.
