What is Agile,advantage and disadvantages

Introduction:-

It is a software development life cycle used for software development, that is characterized by the division of tasks into short phases of work and frequent reassessment and adaptation of plans.

Agile Work Flow:-

THE AGILE ITERATION WORKFLOW: -

• Requirements - Define the requirements for the iteration based on the product backlog, sprint backlog, customer and stakeholder feedback.
• Development - Design and develop software based on defined requirements.
• Testing - QA (Quality Assurance) testing, internal and external training, documentation development.
• Delivery - Integrate and deliver the working iteration into production.
• Feedback - Accept customer and stakeholder feedback and work it into the requirements of the next iteration

MAKING THE AGILE PROCESS WORK FOR YOU:-

• Daily Meetings - Host consistent or daily stand-up meetings to maintain open communication, hold workers accountable, and keep each iteration moving forwar
• Live Demonstrations - Deliver live demonstrations of each iteration’s final product to show progress.
• Share Feedback - Receive feedback from stakeholders and customers and share it with the entire team before the next iteration begin.
• Remain Agile - Make changes to your process based on feedback to ensure each iteration improves the last.

Agile Manifesto:-

•   Individuals and interactions over processes and tools
• Working software over comprehensive documentation
• Customer collaboration over contract negotiation
• Responding to change over following a plan

Principles behind the Agile Manifesto: -

1. Our highest priority is to satisfy the customer through early and continuous delivery of valuable software.
2. Welcome changing requirements, even late in development. Agile processes harness change for the customer's competitive advantage.
3. Deliver working software frequently, from a couple of weeks to a couple of months, with a preference to the shorter timescale.
4. Business people and developers must work together daily throughout the project.
5. Build projects around motivated individuals. Give them the environment and support they need, and trust them to get the job done
6. The most efficient and effective method of conveying information to and within a development team is face-to-face conversation
7. Working software is the primary measure of progress.
8. Agile processes promote sustainable development. The sponsors, developers, and users should be able to maintain a constant pace indefinitely.
9. Continuous attention to technical excellence and good design enhances agility.
10. Simplicity--the art of maximizing the amount of work not done--is essential.
11. The best architectures, requirements, and designs emerge from self-organizing teams
12. At regular intervals, the team reflects on how to become more affective, then tunes and adjusts its behavior accordingly

ADVANTAGES: -

·         Corrections of functional requirements are implemented into the development process to provide the competitiveness

·         Project is divided by short and transparent iterations

·         Risks are minimized thanks to the flexible change process

·         Fast release of the first product version

DISADVANTAGES: -

·         Difficulties with measuring the final cost because of permanent changes

·         The team should be highly professional and client-oriented

·         New requirements may conflict with the existing architecture

·         With all the corrections and changes there is possibility that the project will exceed expected time

Optimization in MVC

1. Optimization is the technique that is used to reduce the size of CSS and Script in bundleConfig.cs
2. It make bundle compact and smaller in size.
3. optimization work in release mode by default it is disable in debug mode.

Syntax Of optimization:-  this syntax is used in the global.asax. we can enable or disable the optimization with the help to set as true or false.

  public class MvcApplication : System.Web.HttpApplication
    {
        protected void Application_Start()
        {
            System.Web.Optimization.BundleTable.EnableOptimizations = false;
        }
    }

All tables name like

ome time we need to get all the tables which start with any character.We have imported data form excel sheet to MS SQL database. Now want to get list of table and delete the imported data table from database.

This query will helpful to get the table from database

SELECT TABLE_NAME FROM INFORMATION_SCHEMA.TABLES

WHERE TABLE_TYPE = 'BASE TABLE' AND TABLE_NAME LIKE '%$%'

Drop all db objects

Some time we need to restore the database with the help of MS SQL server generate script.
We need to flow these Steps

1. Generate Database Scripts(Schema and data)
2. Drop all db objects
3. Restore Generated script   

Drop all db objects

This below script user can use to drop all database objects from database and

1. Store procedures
2. Views
3. Functions
4. Tables

Find and Remove Duplicate Rows in a Table using SQL Server

Syntax:-

--//synatx to find duplicate and count the no of rows
;WITH CTE AS
(
    SELECT ColomnName, ROW_NUMBER() OVER
    (
        PARTITION BY ColomnName ORDER BY ID
    ) RowNumber
    FROM  TableName
)

--// to check duplicate record select command
SELECT *   FROM CTE WHERE RowNumber > 1

--//Delete duplicate  record
DELETE FROM CTE WHERE RowNumber > 1


Example:-

i have the table that contain the duplicate sector

Syntax to select the duplicate record:-

;WITH CTE AS
(
    SELECT name, ROW_NUMBER() OVER
    (
        PARTITION BY name ORDER BY id
    ) RowNumber
    FROM  dbo.Sectors
)


SELECT *   FROM CTE WHERE RowNumber > 1

Syntax to delete the duplicate Data:-

;WITH CTE AS
(
    SELECT name, ROW_NUMBER() OVER
    (
        PARTITION BY name ORDER BY id
    ) RowNumber
    FROM  dbo.Sectors
)
DELETE  FROM CTE WHERE RowNumber > 1
