Practical Agile Concept with Git

Software development models used to develop software production efficient & effective manner.The Systems Development Life Cycle (SDLC) gives structure to the challenges of transitioning from the beginning to the end of your project without forgetting a step.

1. Waterfall Model:oldest and most straightforward
2. V-Shaped Model
3. Iterative Model
4. Spiral Model
5. Big Bang Model
6. Agile Model:By breaking the product into cycles, the Agile model quickly delivers a working product and is considered a very realistic development approach.This model emphasizes interaction, as the customers, developers and testers work together throughout the project.
Manifesto for Agile Software Development introduce in 2000(https://agilemanifesto.org/)

12 Agile principles:These principles describe..
 
    (1)Respect leadership in level
    (2)Start with what you do
    (3)Encourage Changes always.
    (4)Respect current roles & responsibilities. 
Most famous agile Methodologies(Frameworks)
1.Scrum
2.Kanban

Scrum vs Kanban
stresses on planning vs things can change frequently.
Divide to time boxes(2 weeks-mounts sprint) vs continuous deliver process.
Specific role for member(Product owner,scrum master,dev. team)vs Self organize team.
Responsibility to single member vs Share responsibility among all
customer involvement vs customer involvement.
No changes during the Spring vs Changes are acceptable.
Formal(Steep learning curve) vs informal(Simple learning curve)
Performance  measure by Velocity vs Lead time 

Service Desk software serves as a single point of contact for IT support personnel and users of IT solutions.So agile development purposes we can use this kind of softwares
Eg:Github project,JIRA,Trello

Product backlog:A product backlog is a list of the 
a.new features
b.changes to existing features
c.bug fixes
d.infrastructure changes or other activities
that a team may deliver in order to achieve a specific outcome.We enter these context using support ticket.
User Stories->Use Cases->Support ticket->Issue

2.Kanban
(a)Kanban using Trello


Generally there are 4 parts in the board
                1.product backlog
                2.WIP(Work in progress)
                    WIP Limit=(# of dev. team x 2 or 1.5->Do not add support ticket more than WIP Limit)
                3.Holted
                   Also can add hold limit with discuss with dev.team
                4.Done
                     Lead Time=(Done time-Starting point)->Try to reduce that

(b)Kanban using Git Project
Sample Git Project


                                                                                                                               Will be continue..

1.INTRODUCTION Java EE(Enterprise edition Java) Simply EE focus to develop enterprise application development.The aim of the Java EE platform is to provide developers with a powerful set of APIs while shortening development time, reducing application complexity, and improving application performance. Java EE vs Java SE JDK(Java Development Kit)     Java SE API     JRE(JVM)     Development Tools(Eg:-Javac,Serial version UID,etc) Java EE based on java SE.In the java SE we can develop anything;Also EE application but that develop must concern cross cutting component.But in the Java EE developer can focus one develop the business logic, Lesley thinking about security,transaction,error handling,login etc. JAVA SE gives a collection of specification(like documentation)+their implementation. JAVA SE gives  only specification.So several external companies implement that methods several ways Eg:-Hibernate,Jetty,Apache Tom Cat,Glass fish                      Companies implement java EE specific

Avoid Round-off error in large & Small numbers using BigDecimal Class in Java

Image
                    There are two types of primitive data types used for floating point representation in java called double & float.float is a 32 bit IEEE 754 single precision Floating Point Number & double is a 64 bit IEEE 754 double precision Floating Point Number.So that double has 2x more precision then float. double d1=.3; double d2=.2; double d3=d1-d2; System.out.println(d3);//IEEE754 Result is 0.09999999999999998 But there is a round-ff error in IEEE745 floating point representation in double.So when these data apply to large scale project it will possible to fail(GPS Systems,Banking Systems,Radar System,Air traffic controlling systems etc.) So avoid that drawback java introduce Class called BigDecimal.Big decimal avoid this problem(But it consumes more space & time complexity than decimal.) //using as String BigDecimal b1 = new BigDecimal(".3"); BigDecimal b2 = new BigDecimal(".2"); BigDecimal b3 = b1.subtract(b2); System.out.println(b3); //But
