Modern software tools often have the capability to auto-generate enormous amounts of code with a few clicks of a mouse. Maintainability measures how easily software can be maintained. During the last few years, Ethereum block explorer services have emerged as a popular project to explore and search Ethereum blockchain data such as transactions, addresses, tokens, smart-contracts' source code, prices and other activities … They are used to measur… The work involved in creating this code cannot reasonably be compared to the work necessary to write a device driver, for instance. Complexity metrics also provide feedback during the software project to help control the [design activity]. In this case study, the five software metrics- lines of code (LOC), cyclomatic complexity (MVG), Halstead volume (HV), number of modules (NOM) and lines of comment (COM) have been utilized to analyze a set of three java based sorting programs. Problems with multiple languages: in today's software scenario, software is often developed in more than one language. In this case study, the five software metrics- lines of code (LOC), cyclomatic complexity (MVG), Halstead volume (HV), number of modules (NOM) and lines of comment (COM) have been utilized to analyze a set of three java based sorting programs. An intuitive metric: line of code serves as an intuitive metric for measuring the size of software because it can be seen, and the effect of it can be visualized. Software Metrics Product vs. process Most metrics are indirect: ... ‘‘The nature of the software engineering process is too poorly understood to provide a basis for selecting a ... Programmer Productivity Metrics (2) Take total number of source code lines delivered and divide by E=1.4L 0.93 DOC=30.4L 0.90 D=4.6L 0.26. Process Metrics:These are the measures of various characteristics of the software development process. This section focuses on "Software Metrics" of Software Engineering. The following example shows a comparison of a "hello world" program written in C, and the same program written in COBOL - a language known for being particularly verbose. Specific definitions of these two measures vary, but the most common definition of physical SLOC is a count of lines in the text of the program's source code excluding comment lines.[1]. This model is an example of the static, single variable model. You just clipped your first slide!

Using lines of code to compare a 10,000-line project to a 100,000-line project is far more useful than when comparing a 20,000-line project with a 21,000-line project. Some of the product based metrics that measure the source code related attributes of a software product are Object Oriented metrics (CK suite) , Halstead metrics , McCabe metrics , and line of code metrics. Text lines are no longer limited to 80 or 96 columns, and one line of text no longer necessarily corresponds to one line of code. They are extracted from the source code of the software, and their values allow us to reach conclusions about the quality attributes measured by the metrics. 2. There are two major types of SLOC measures: physical SLOC (LOC) and logical SLOC (LLOC). It was one discrete object that was easily counted. On the other hand, process based metrics that measure the changing nature of the software are collected over a certain period of time and might be related to developers, revisions and source code changes. 2 logical lines of code (LLOC): what about all the work writing non-statement lines? In many cases, an open source project attracts other developers who contribute to the project. As you might imagine, every source had their own theories about which metrics mattered most. Process is placed at the centre of the triangle connecting three factors (product, people, and technology… The goal behind using precise metrics and measurement in software engineering is to identify and control what can affect software development and the project as a whole. Increase return on investment (ROI) 2. Very often, a number of languages are employed depending on the complexity and requirements. Resources for measuring and assessing software quality. Having some heuristics and metrics that measure an application’s source code provides a useful starting point, and observing these metrics over time can identify important trends. / * now how many lines of code is this design activity ] other developers contribute!
