In this tutorial we are going to learn about the Software Development Life Cycle, which includes the following topics:- . Iterative model  . When to use Iterative Model . Advantages/Disadvantages of Iterative model . Spiral model . When to use Spiral Model . Advantages/Disadvantages of Spiral model The Fifth mode l of SDLC is "Iterative Model" . This is the Fifth model of SDLC after Spiral model. This model is also called as Incremental model .Let us discuss about the Iterative model in Detail :- Iterative model :- Software development with the help of this model leads to a development process in iterations. Incremental development divides the system functionality onto portions basically called increments.It is the process of develop the software in increments. At first, the process is developed at very small scale by following all steps into consideration.These process groups Iteration into phases. i.e. inception, elaboration,construction...

Software development process, commonly known as Software development life cycle, is a process used by the software industry for designing, development and testing high quality software. The Aim of Software development life cycle(SDLC) is to produce high-quality software that meets i.e. exceeds customer expectations, and also reaching completion within the cost estimates and within time. The framework of SDLC is to define tasks performed at each step in the software development process. In this tutorial we are going to learn about the Software Development Life Cycle, which includes the following topics, What is SDLC? Stages of SDLC Models of SDLC Conclusion What is SDLC? The process followed by software project within the software organization is called software development life cycle. Basically its consists of detailed plan which describe how to develop, maintain a software, replace and alter or enhance specific software . SDLC “Life cy...

Hello Everyone, Please make use of this Top 50 Manual Testing Interview Questions and Answers to crack the interview easily, 1.What is Software Testing? Software testing is the process of evaluating a system to check if it satisfies its business requirements. It measures the overall quality of the system in terms of attributes like correctness, completeness, usability, performance etc. Basically, it is used for ensuring the quality of software to the stakeholders of the application. 2.What are Verification And Validation? Verification: process of evaluating work-products of a development phase to determine whether they meet the specified requirements for that phase. Validation: process of evaluating software during or at the end of the development process to determine whether it specified requirements. Difference between Verification and Validation: •Verification is Static Testing where as Validations is Dynamic Testing. •Verification takes place before validation. •Ve...

1.Which type of language is Python ? Interpreted or Compiled ? Python is an interpreted, interactive, object­ oriented programming language.Python is an interpreted language, as opposed to a compiled one, though the distinction can be blurry because of the presence of the bytecode compiler. This means that source files can be run directly without explicitly creating an executable which is then run. 2. What do you mean by python being an “interpreted language”? An interpreted languageis a programming language for which most of its implementations execute instructions directly, without previously compiling a program into machine­languageinstructions. In context of Python , it means that Python program runs directly from the source code. 3. What is python ’s standard way of identifying a block of code? Please provide an example implementation of a function called “my_func” that returns the square of a given variable “x”. (Continues from previous question) ...

In my last Blogs we have discussed about What is Big data hadoop and its jobs ? Apache Spark and Introduction of Apache Spark SQL .Now in this blog we will discussed about the basic frame work of Hadoop. So lets gets started. Frameworks: Hadoop : Hadoop is basically a software library written in java. It is used for processing large amount of data in distributed environment, which allows developers to setup clusters of computers starting with a single node that can scale up to thousand of nodes. HIVE Hive is data warehousing framework that's built on Hadoop. It allows for structuring data and querying using a language like SQL called HiveQL. Developers can use Hive and HiveQL to write complex MapReduce over structured data in a distributed file system. Hive is the closest thing to a relational-database in the Hadoop ecosystem. PIG Pig is an application for transforming large data sets. Like Hive, Pig has its own language called pig-latin. Pig Latin allows devel...
