model, each phase must be completed in its entirety before the next phase begin. At the end of each phase, review takes place to determine if the project is on the right path and whether or not to continue or discard the project. In this model the testing starts only after the development is complete. In waterfall model phases do not overlap.

thousands here in our country and millions around the world. 2. Sub point 2: These cars doesn’t require a human assistance, therefore anyone is capable of driving. Disabilities would no longer be a factor in driving and elders who aren’t capable of manual driving can benefit more out of this car. Transition (signpost, summary, preview): Now that you have a better understanding of the self-driving cars advantages. I will now discuss its
Three decades before no one wondered of open source or free to air concept, but it came into existence almost then; two decades before. Yet debates transpire about its usefulness and disadvantages. However, mass percentile benefits from it as its affordable & highly customizable for innovation driven businesses. Open source software is fundamentally related to sharing and gaining wisdom from the communities. Open source, still gaining popularity compared to proprietary and it's burgeoning as more
facilitate the creation and maintenance of a computerized database. Evolution of Database Management Systems The revolution of database management systems were began on mid-1960s. Before that data was stored as paper records. It contributes a lot of disadvantages. Because of that people used to search another way to store their important data more safely and easily. As a result of that file-based system was introduced. It is easier to handle data with file based systems than using paper records. File –
clarify requirements, which are not clear, hence reducing ambiguity and improving communication between the developers and users. 4. Users are actively involved in the software development. 5. Helps in reducing risks associated with the software. Disadvantages of Prototyping Model 1. If the user is not satisfied by the developed prototype, then a new prototype is developed. This process goes on until a perfect prototype is developed. Thus, this model is time consuming and
works well with linear data storage type, such as tape. • Model relates very well to natural hierarchies, such as assembly lines and workers' organizations in the society. • This also applies in the case of works by one-to-many relationship. Disadvantages of Hierarchical Data Model • They needed to re-stored data in different individuals. • The database can be very slow when searching for information on subpages. • We no longer use linear memory environments, such as tape, so that the advantage
Harvesting Harvesting is the process of collecting the mature rice crop from the field. It starts with cutting the crop and ends with cleaning the paddy and preparing it to be dried. Harvesting at the right time and in the right way maximizes grain yield and minimizes grain losses and quality deterioration. Conventional harvesting method is highly labour intensive and inefficient in terms of both economy and time. Machine harvesting systems are a partial solution to overcome these issues by

Discuss how computer-Aided software engineering (CASE) is used to aid companies to be more productive. What is CASE? Computer Aided Software Engineering (CASE) was ‘born’ in mid 1970s with the basic purpose to speed up the software structure process. Core purpose of every business and company is profit, by using every method. Businessmen have keen eyes on market, supply chains, demands and methods of production. ‘Targets’ and there completion is very important in every business. Fast tracks to
