     • Unique - Guarantees unique values for the column(or set of columns) included in the index
     • Covering - Includes all of the columns that are used in a particular query (or set of queries), allowing the database to use only the index and not actually have to look at the table data to retrieve the results
     • Clustered - This is way in which the actual data is ordered on the disk, which means if a query uses the clustered index for looking up the values, it does not have to take the additional step of looking up the actual table row for any data not included in the index.

     OdeToCode has a good article covering the basic differences

     As it says in the article:

     Proper indexes are crucial for good performance in large databases. Sometimes you can make up for a poorly written query with a good index, but it can be hard to make up for poor indexing with even the best queries.

     Quite true, too... If you're just starting out with it, I'd focus on clustered and composite indexes, since they'll probably be what you use the most.

     I'll add a couple of index types

     BITMAP - when you have very low number of different possible values, very fast and doesn't take up much space

     PARTITIONED - allows the index to be partitioned based on some property usually advantageous on very large database objects for storage or performance reasons.

     FUNCTION/EXPRESSION indexes - used to pre-calculate some value based on the table and store it in the index, a very simple example might be an index based on lower() or a substring function.

   • What are the different types of encapsulation?

     You're thinking too much I think.

     http://en.wikipedia.org/wiki/Information_hiding

     Excerpt from this article:

     Information hiding in computer science is the principle of hiding of design decisions in a computer program that are most likely to change, thus protecting other parts of the program from change if the design decision is changed. The protection involves providing a stable interface which shields the remainder of the program from the implementation (the details that are most likely to change).

     One common form of encapsulation is using properties to hide private data fields. An even more common form is the use of OO to encapsulate the complexity of software into well divisoned classes with roles and responsibilities. This is a key tennant of OO, as it moves from a monolithic procedural design style to a more structured style which strives to hide all irrelevant information except that which pertains to the particular task your working on.

   • What are the different types of Equality?

     A crucial premise of a self-governing community is the belief in inequality. Equality does not imply perfect equality. Equality comes from the Latin words aequalis, aequus, and aequalitas. All of these are old French or Latin terms. Even, level, and equal are the meanings of these French/Latin words. In general, equality means that everyone receives the same treatment and rewards. It is required as a matter of natural equality. All men are regarded to be born natural and free.

     Despite a great emotional appeal to people’s hearts, the concept of natural and perfect equality for everyone cannot be fully recognized and realized. Men are not equal in terms of physical characteristics or mental aptitude. Some are stronger than others, while others are more intelligent and talented. Actually, equality means that everyone should have equal possibilities to flourish. In fact, when we speak about equality for all people, we are referring to broad and equitable equality rather than perfect equality. In political science, equality is distinguished from uniformity, identity, and similarity. Of course, some individuals wish to use it to indicate consistency. When employed by political scientists, however,...
