Statistic analyze is the computer software analysis performed by not actually executing the software that is being tested. Static analysis doesn’t include dynamic execution of the software under test and can detect potential defects in an early stage, prior to running the program. It can be achieved by a machine to automatically “walk through” the source code and detect noncomplying codes. A compiler which finds lexical, syntactic and even some semantic mistakes can be given as a classical example. It can find weaknesses in the code at the exact location.
Static analysis can also be carried out by a person who would review the code to provide correct coding standards and conventions are used to construct the program. This is generally called Code Review and it is done by a peer developer, someone apart

The defect gets more expensive as long as the defect persists. One of the most crucial advantages of static analysis is the detection of defects earlier during the process when they are easier and more cost effective to fix. Other advantages involves removing program components that are not necessary and ensuring that the software being analyzed is compatible with other programs that are likely to be run concurrently.
Another advantage of using static code analysis is you can define your project specific rules, and they will be guaranteed to follow without any manual intervention. In case any team member forgets to follow those rules, static code analyzer will highlight them like fortify or find bugs.
As the static testing is faster and achieves 100% coverage, the unit cost of detecting these bugs by static testing is much lower than detecting bugs by dynamic testing. If you have an urgent deadline looming on the horizon, the part where you use dynamic testing tools can be omitted. However, tool-supported static testing should in no case be
Security Analyst: Scans the application, triage it and comes out with the Security Assessment report.
Data Analysis is defined as "Procedures for analyzing data, techniques for interpreting the results of such procedures, ways of planning the gathering of data to make its analysis easier, more precise or more accurate, and all the machinery and results of (mathematical) statistics which apply to analyzing data. (Statistician John Tukey, 1961)” In general, Data Analysis is used to check the validation of the vaguely collected data in terms of variations and profitability. However, if Data Analysis is not used we cannot obtain the accurate, factual and optimum solution of the given challenge. Data Analysis tools helps us to understand the question and produces answer in a detailed space. It also helps to find the gaps between data such
One of the project problems mentioned by Brooks Jr. in Chapter 12 of his book “The Mythical Man Month” is the problem with program maintenance. According to him fixing a bug has around 20 to 50% chances of introducing another one. As explanation he shows two reasons: first one is that in most of the projects the structure of documentation in not clear, precise and does not describe all dependencies that exist in the system and second is that the programmer who is repairing the system is typically not the same as the one who composed the code at development (Brooks Jr., 1995). So in order one project not to fail there should be more system testing per statement written then in the other cases. Brooks suggest that after fixing each bug an entire bank of previous test cases should be run against the system (Brooks Jr., 1995). But
Advantages of using software to code data include data collection and storage, as the software permits a variety of information, data, and content types to be collected and stored together. It also allows the researcher to link information, nodes, or documents with one another for a more holistic analysis. Compared to coding by hand, software often provides a researcher with additional tools for coding and analysis (i.e. auto coding) that s/he would not otherwise have. It also permits the
In addition, It also provides a solid structure that can minimize unused effort, which make it work well as soon as the development team is inexperienced or less technically competent. Furthermore, it works well for smaller projects where requirements are very well understood.
Static, static, static; but what does all this static mean? Re occuringly, our reading material conveys the idea of static members. During the course of chapter five, I develop a keen understanding on how to use static members, say variables and methods.
i.The user can organize their program into smaller programs which helps better maintaining the code.
First, we look what is the difference between system analysis and system design. System analysis is a problem-solving technique that decomposes the system into its component pieces and system design is a complimentary problem-solving technique that reassembles the component pieces of the system back into a complete system. When we are developing an information system, most organizations use a standard of steps. The steps are called development lifecycle(SDLC). SDLC consists of phases such as planning, analysis, implementation, design, and maintenance. Analysis phase is where you take a closer look and study the current system. The design phase, analysts design all aspects of the system, specifying on the system from input and output screens to database, computers, and report processes.

It requires new skills, that a traditional software development house will not have. In particular, you may have to retrain/hire people in the following areas:
To do statistical analysis, you need to use the appropriate software. It has to be special software for managing data and calculating a wide variety of statistics.
Before there are any ways to catch the Defects, Test cases or use cases, Companies utilized Excel to keep up the data, Requirement Tractability furthermore the status of the deformity. As the quantity of cycles are expanding and number of the general population additionally expanding, it is essential to utilize a solid system for catching the data it is possible that it might be experiments, deformities or Requirements so that as opposed to recording analyzers can focus more on finding the Bugs.
To know how error analysis works, firstly it should know what an “error” is and its possible sources. When it comes to the definition of errors, many researchers have given their own ideas. Corder
4. It enables the development team to discover potential errors and weak spots before a proper implementation which might be too expensive to correct
