Types of Software Development Models
When initiating a new software development project, it is essential to consider different steps that broadly impact its final rollout phase.
This will ensure the software functions appropriately and effectively by providing the intended solutions. Therefore, the steps required for a software to work properly include; development, testing, coding/implementation, and frequent maintenance.
Whichever app or software you are creating, proper development and the testing plan are vital aspects to consider to realize success in completing any project.
In addition, the development plan by the developer’s guides in seeking an appropriate model for building an app with required functionalities based on clients’ specific needs. It also provides room for developing authentic and safe apps or software for numerous individuals or companies.
What are software development models?
Software development models are the numerous methodologies selected to develop a project by considering the goals and aims of the project. Several cycle models with specific structures can currently achieve different objectives appropriate for creating a required software or app.
The models manage the tasks at various stages, from initial feasibility to completion. Since software development services are complicated processes, it becomes vital to utilize the varied development models for smooth and desired success.
Let’s look at the different types of software development models.
Waterfall model
The waterfall model is a steady development process of software in a linear flow from the initial to the implementation phase. Only one step begins after the previous stage has finished. Its development stages include; design, analysis, testing, coding, and deployment, meaning the process takes a cascade mode.
The waterfall model takes place where software requirements are not re-evaluated further in the development process. It is productive in projects that don’t anticipate future unforeseen changes at the development stages. This results from the model not supporting going backward to completed phases.
Merits and demerits of the waterfall
Merit: It is simple and easily understandable. The waterfall is an ideal and manageable model for handling small projects whose proven requirements are in the final phase.
Demerit: Its structure is rigid. The rigid structure of the waterfall model makes it hard to work well when developing complex projects that need changes at different phases of development.
V-model
The v-model is an integrated extension of the waterfall model with its move bending upwards after the coding and implantation phase. It’s different from the v-model since the testing planning process is at the early stages. The movement of the process is downward, then upwards. Therefore, every downward sequence corresponds with an upward sequence.
Merits and demerits of V-model
Merits: Simple to use with specific deliverables. The model is highly productive since it yields a greater success rate due to regular test plans at various phases.
Demerits: V-model is very inflexible. The rigid structure of the v-model makes it not ideal for projects with unpredictable upgrades in the future.
Incremental model
The incremental model comprises iterative developmental stages divided into smaller sections. The smaller sections allow software developers to take insights and learn from previous development phases.
Merits and demerits of incremental model
Merits: the incremental model enables Increased and improved user involvement. The model offers an exceptional solution to projects that need changes like upgrading.
Demerits: preliminary analysis: users can get confused about the prototype within the finished system.
RAD model
The complete form of the name is Rapid Application Development. The RAD model is a re-adjusted incremental model with several components developed concurrently and compiled into working prototypes.
Merits and demerits of the RAD model
Merits: Reduced time for development. The model allows immediate customer feedback in the development phases of the software.
Demerits: Applicability of the RAD model takes a limited approach. Most projects can be divided into several increments with excellent planning and modeling skills that need highly experienced developers. Issues resulting from assembling components at the final phase bring unforeseen setbacks.
Agile model
The agile model is an entrenched process in user engagement and adaptability alongside deliverables of software components with unique functioning. The elegant model comprises incremental and iterative features because it divides the product development into smaller increments provided in bits of iterations.
Merits and demerits of the agile model
Merits: Efficient time management process. The model aligns continuous feedback and communication to the path of clear direction.
Demerits: The agile model is prone to veering-off track because the method relies on the end-users interaction.
Iterative model
The model considers specific parts in software for the implementation process rather than starting with packed requirements. After a product is built within an iteration, it is analyzed and improved in the next iteration phase. The model depends mainly on the step-by-step development process of the creation.
Merits and demerits of iterative model
Merits: Identifying problems is easy. Using this model, the development of a product is gradual, making it easy to trace issues promptly.
Demerits: The phases of iteration are rigid. The iterative model phases do not overlap because they are inflexible, making them slow and costly.
Prototype model
The model depends on different software and system application versions to visualize numerous components of the software. The model is essential in limiting the gap of understanding by providing ample collaboration and timely feedback by users.
Merits and demerits of prototype model
Merit: The model is efficient in yielding reduced time and development costs since the user is heavily relied upon
Demerits: Confusion can quickly arise between prototype and final product, resulting in more development time for the prototype.
Spiral model
The spiral model integrates both waterfall and iterative model elements to combine bottom-up and top-down production methods. The model comprises four phases: design, identification, evaluation, and risk analysis.
Merits and demerits of the spiral model
Merit: manages risks by dividing the development process into phases. This ensures accurate estimates can be done for the budget after problems are discussed earlier.
Demerits: the model is primarily customized, making the repurposing process confusing. The model needs experienced individuals with good at-risk evaluation.
Conclusion
Software development models work based on their features. Combining the models can help in improving the functionality of applications and software in the development phases.

US: A Judge Mandates that Google Allow Competing App Stores to Access Android
(VOR News) – The ruling is that Google, the greatest technology firm in the world, is required to make its Android smartphone operating system available to merchants that supply applications that are in direct rivalry with Google’s. This decision was reached by a judge in the United States of America.
The Android Play store, which is owned and operated by Google, was found to be an example of an illegal monopoly arrangement by a jury in the state of California on Monday. The finding was reached by a jury. Monday is the day that this decision was come to.
An earlier federal judge ruled Google’s search engine illegal.
This finding, which came after that decision, has forced the company to suffer yet another setback. As a result of the corporation having already encountered its initial obstacle, this decision has been established. This particular decision was made by the judge during the month of August, when the month was in progress.
In light of the fact that the decision was made, what exactly does it mean that the choice was accepted?
In accordance with the verdict, Google is obligated to make it possible for users to download Android app stores that are offered by third-party competitors. For a period of three years, the corporation is prohibited from imposing restrictions on the usage of payment mechanisms that are integrated into the application.
In addition, it is important to keep in mind that Google does not possess the right to impose restrictions on the utilization of ways to make payments online.
Additionally, the verdict makes it unlawful for Google to give money to manufacturers of smartphones in order to preinstall its app store. Smartphone manufacturers are prohibited from doing so.
Furthermore, it prevents Google from the possibility of sharing the revenue that is generated by the Play store with other companies that are in the industry of delivering mobile applications.
In addition to this, the court has mandated the establishment of a technical committee that will be made up of three different people chosen at random.
The committee will be responsible for monitoring the implementation of the reforms and finding solutions to any disagreements that may occur as a consequence of the implementation of the reforms while they are being implemented. This task will fall under the committee’s purview so that it may fulfill its duties.
However, certain components were allowed to be put into action until July 1st, despite the fact that the judge’s statement suggested that the ruling would take effect on November 1st. The statement was the basis for the ruling, which ultimately became effective.
Particularly, I wanted to know what Google’s reaction would be.
There is a fact that Google does not adhere to this directive, which has been brought to their attention. This document argued that the alterations that the judge had ordered to be made would “cause a range of unintended consequences that will harm American consumers, developers, and device makers.”
The judge had ordered the modifications to be implemented. The alterations were to be carried out as indicated by the judge’s ruling. The judge made it clear that he expected these revisions to be carried out in accordance with his guidance.
The company’s regulatory affairs vice president, Lee-Anne Mulholland, provided the following statement: “We look forward to continuing to make our case on appeal, and we will continue to advocate for what is best for developers, device manufacturers, and the billions of Android users around the world.”
On average, over seventy percent of the total market for smartphones and other mobile devices is comprised of mobile devices that are powered by the Android operating system. Both smartphones and other small mobile devices are included in this category.
In the event that the Play app store continues to be shown on the home page and that other Google applications are pre-installed prior to the installation of the Android application, smartphone manufacturers are entitled to install the Android application at no cost at their discretion.
Additionally, the Android application can be installed on devices that are manufactured for smartphones.

WhatsApp Now Features a “Mention” Tool for Status Updates and Stories.
(VOR News) – Those who use WhatsApp now have the ability to mention other people in their stories or status updates as a consequence of a feature that was only recently enabled on the platform.
Previous to this point, this capability was not available. It wasn’t until quite recently that this capability became available to the public.
According to the information that was provided by the company, users now have the opportunity to tag close friends in their stories, and the person who is mentioned will have the option to go back and re-share an earlier version of that story. This information was provided by the company. The corporation was kind enough to reveal this information to us.
Because of a new feature that has been added to the WhatsApp app, users now have the opportunity to like individual stories and status updates.
This capability was previously unavailable to WhatsApp users.
A significant amount of progress has been made in this context. Alternative readers now have the chance to “like” a work, which is comparable to liking a post on Facebook. This feature was introduced in recent years. When compared to the past, this is a tremendous shift.
At one point in time, viewers were only permitted to observe the total number of views that a particular story had gotten. These restrictions were eliminated in later versions of the software.
Additionally, it is essential that the likes and reactions to a story be kept anonymous during the entire process. One of the factors that contributes to the general mystery that surrounds this characteristic is the fact that this is one of the elements.
The person who brought it to the attention of others is the only person who will be able to judge who enjoyed it and who did not care about it. These individuals will be able to make this determination.
A notification will be issued to the individual who was referenced earlier in the sentence and who was named in the story or status update that was discussed. A notification of this nature will be sent to the individual via WhatsApp.
This message will be sent to the user in question whenever that person makes a reference to another person while they are in the process of elaborating on a narrative or updating their status. You will receive a notification alerting you that you have been tagged in the narrative.
This notification will be delivered to the person who receives this message. In addition, students will be provided with the opportunity to re-share the tale for themselves.
It is important to note that if the names of individuals who have been referenced in a narrative or a status update are included in any of these, then the names of those individuals will not be accessible to any third party through any of these. In light of the fact that the identities of those individuals will be concealed from public disclosure, this is the condition that will be required.
While WhatsApp recently made the announcement that it will be incorporating this functionality, it is highly likely that not all users will have access to it at the same time.
This is despite the fact that WhatsApp recently made this announcement.
Despite the fact that WhatsApp has only recently made a public announcement that it will move forward with the deployment, this is the situation that has presented itself.
As soon as a short period of time has elapsed, access will be made available to each and every person on the entire world.
Additionally, WhatsApp has hinted that new functionalities might be introduced to the status and updates tab in the future months.
The purpose of these capabilities is to provide users with assistance in maintaining healthy connections with the individuals who play a vital role in their living experiences. This is done in order to give users with support in maintaining close relationships with the folks who are the subject of the inquiry.
It is with the purpose of supporting users in successfully keeping close ties with the individuals in question that this step is taken.

Over The Planned “Link Tax” Bill, Google Threatens to Remove NZ News Links.
(VOR News) – Google has sent a strong message to the New Zealand government, threatening to stop boosting local news content should the Fair Digital News Bargaining Bill become law.
The law, put up by the Labour government and backed by the coalition in power at the moment, mandates that digital companies such as Google pay back news organizations for links to their material.
News publishers, on the other hand, charge the tech giant with “corporate bullying.”
Google says this measure may have unanticipated effects.
Google New Zealand’s country director, Caroline Rainsford, voiced her worries that the law, which is being referred to as a “link tax,” is not doing enough to support the media industry in New Zealand right now.
She underlined that Google would have to make major adjustments if the previously mentioned law were to pass, including cutting off links to news articles from its Search, News, and Discover platforms and cutting off financial ties with regional publications.
According to Rainsford, similar legislation has been proposed and approved in other nations including Australia and Canada, but it has not been proven to be effective there and breaches the principles of the open web.
She drew attention to the fact that smaller media outlets will be most negatively impacted, which will limit their capacity to reach prospective audiences.
Google says its alternative options will protect smaller, local media from negative effects.
Conversely, it conveys apprehension regarding the possible fiscal obligations and vagueness of the legislation, which it feels generates an intolerable level of ambiguity for enterprises functioning within New Zealand.
The New Zealand News Publishers Association (NPA) has reacted to Google’s warnings by alleging that the internet behemoth is using coercive tactics.
They specifically contend that the need for regulation stems from the market distortion that Google and other tech giants have created, which has fueled their expansion into some of the most significant corporations in global history.
The legislation aims to create a more equal framework that media businesses can use to negotiate commercial relationships with technological platforms that profit from their content.
New Zealand Media Editors CEO Michael Boggs stated that he was in favor of the bill, citing the fact that Google now makes a substantial profit from material created by regional publications.
He also emphasized that the use of artificial intelligence by Google—which frequently makes references to news articles without giving credit to the original sources—highlights the significance of enacting legislation.
Paul Goldsmith, the Minister of Media and Communications, has stated that the government is now evaluating various viewpoints and is still in the consultation phase.
He stated that the government and Google have been having continuous talks and will keep up these ongoing discussions.
However, not all political parties accept the validity of the Act.
The ACT Party’s leader, David Seymour, has voiced his displeasure of the proposal, saying that Google is a game the government is “playing chicken” with. He threatened the smaller media companies, saying that they would suffer from worse search engine rankings if the internet giant followed through on its promises.
Seymour contended that it is not the government’s responsibility to shield companies from shifts in the market brought about by consumer preferences.
The things that have happened in other nations are similar to what has happened in New Zealand.
Google has agreements with a number of Australian media firms that are in compliance with its News Media Bargaining Code. These agreements contain provisions that permit an annual cancellation of these agreements.
Due to the government’s decision to exempt Google from the Online News Act, the company has committed to supporting news dissemination by contributing annually to the Canadian journalistic community.
The New Zealand measure is consistent with global approaches aimed at regulating the relationships that exist between technology corporations and media organizations.
It’s hard to say what will happen with the Fair Digital News Bargaining Bill as the discussion goes on. Google and the New Zealand media landscape are preparing for what might be a protracted legal battle.
