   • What are the different types of indexes, what are the benefits of each?

     Top Answer

     Answered Sep 25, 2008 · 31 votes

     • 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 is the cascading order of the three types of CSS ?

     Cascading Style Sheets (CSS) is a style sheet language used for describing the look and formatting of a document written in a markup language. One of the most important aspects of CSS is the cascading order, which determines the priority of styles applied to an element. In this article, we will explain the different cascading methods that can be used inside the cascading order.

     The Cascading Order in CSS is a set of rules that determine which style will be applied to an element when multiple styles are conflicting. These rules can be used to achieve a desired layout or design, but understanding how they work is crucial to effectively use CSS. In this article, we will explore the different cascading methods that can be used inside the cascading order. First, let’s understand the basic concept of cascading. The term “cascading” refers to the way that styles are inherited and applied to elements in a web page. The cascading order is the order in which styles are applied, with more specific styles taking precedence over more general styles.

     Three main cascading methods are:

     • Specificity
     • Inheritance...

   • What are the types of statistics?

     Statistics is a branch of science that deals with the ability to grasp different outcomes from it and foresee several possibilities of various events.  It is used to capture the various possible indicators of central tendencies and the divergence of various values from the center. The facts and figures are first collected. They are then classified and interpreted by subjected to various different methods and approaches to arrive at conclusions. It basically is the study of the following features: 

     • Data collection
     • Classification
     • Analysis
     • Interpretation
     • Presentation
     • Organization in a specific way.
     • Display of numerical methods

     Types of Statistics

     There are majorly two different types of statistics: 

     • Descriptive statistics
     • Inferential statistics

     Descriptive Statistics

     Descriptive Statistics is used to summarise the data through a given set of observations and illustrations. The given data set is summarized from a sample of the population using some of the formulae such as computation of the mean or standard deviation of the given observation. For instance, descriptive statistics are used for the data collection of...

   • What are the types of deadlocks?

     Top Answer

     Answered Mar 27, 2015 · 8 votes

     Two types of deadlocks can be considered:

     1. Resource Deadlock

     Occurs when processes are trying to get exclusive access to devices, files, locks, servers, or other resources.

     In Resource deadlock model, a process waits until it has received all the resources that it has requested.

     The resource model is also called the AND model. In this model, a deadlock occurs if and only if there is a cycle of waiting processes, each dependent on the next process in the cycle to make progress.

     Possible situation: Transaction-processing scenario

     2. Communication Deadlock

     Also referred to as Communication deadlock model, occurs when process A is trying to send a message to process B, which is trying to send a message to process C which is trying to send a message to A.

     The communication deadlock model is also called OR model.

     Evidently, it easily satisfies the Circular-wait condition for deadlock to occur.

     Possible situation: Message-passing scenario

     Hope this will work for you and satisfy the questioner.

    What is First-Order Logic? First-order logic is a logical system for reasoning about properties of objects. Augments the logical connectives from propositional logic with predicates that describe properties of objects, functions that map objects to one another, and quantifers that allow us to reason about many objects at once.
