Clustered Index	Non-clustered Index
Clustered index will be created by default when you create primary key on a column. So we can create one clustered index per table.	Non clustered index will be created automatically when you create unique key on a column. A table can have no.of unique keys, so we can create no.of non-clustered indexes per table.
The Leaf Level of a clustered index is the actual data page.	The Leaf Level of a non-clustered index does not consist of the actual data page.
Only one clustered index can be created.	Many non clustered index(Numbers depends on the database software) can be created.

If the client reports any bug that is called Defect Leakage.
These are the defects which are not identified during the software testing process but found by the clients and given as feed back.
It is calculated as. (Number of defects slipped)/(Number of defects received-Number of defects withdrawn)*100.

An exposed or unidentified bug which exists in the system over a period of time is known as the Latent Bug. The bug may persist in the system in one or more versions of the software.
The bug which is not identified in present version and can be able to identified in Later versions.

Gap analysis is a business resource assessment tool enabling a company to compare its actual performance with its potential performance.
It’s a formal Study of what business is doing today and can be conducted in different Prespectives, like.
- Organization (e.g., human resources).
- Business direction.
- Business processes.
- Information technology.

Gap analysis

The three steps to follow the gap analysis,
- Analyze your current state
- Identify the ideal future state
- Bridge that gap

Start your current state analysis can include qualitative information such as team processes/methodologies, and quantitative information, such as the number of sales calls made each week.
In fact, your gap analysis process should evaluate everything you currently do so you get the “great image.”

The gap analysis report should also include a column labeled “Future State,” which outlines the target condition the company wants to achieve.
Like the current state, this section can be drafted in concrete, quantifiable terms, such as aiming to increase the number of fielded customer calls by a certain percentage within a specific time period; or in general terms, such as working toward a more inclusive office culture.

This gap analysis report should list all the possible solutions that can be implemented to fill the gap between the current and future states.
These objectives must be specific, directly speak to the factors listed in the gap description above, and be put in active and compelling terms.
Next steps include hiring a certain number of additional employees to field customer calls; instituting a call volume reporting system to guarantee that there are enough employees to field calls; and launching specific office diversity programs and resources.
