Scratch is a high-level, block-based visual programming language and website aimed primarily at children as an educational tool, with a target audience of ages 8 to 16. [9] [10] Users on the site can create projects on the website using a block-like interface.
It is a teaching and learning robot designed to teach programming. Children can build a robot from scratch and learn about a variety of robotic machinery and electronic parts. It also teaches the fundamentals of block-based programming, and helps children to develop their logical thinking and design skills. [21] MBot Ranger; Multiform land explorer

Software design is the process of conceptualizing how a software system will work before it is implemented or modified. [1] Software design also refers to the direct result of the design process – the concepts of how the software will work which consists of both design documentation and undocumented concepts.
In software engineering, a software design pattern or design pattern is a general, reusable solution to a commonly occurring problem in many contexts in software design. [1] A design pattern is not a rigid structure that can be transplanted directly into source code. Rather, it is a description or a template for solving a particular type of ...
Visual Basic for MS-DOS VB DOS icon. Project 'basic Thunder' was initiated in 1990. [25] Thunder persisted through to the last release of Visual Basic in the name of the primary internal function, "ThunderRTMain". Visual Basic 1.0 (May 1991) was released for Windows at the Comdex/Windows World trade show in Atlanta, Georgia.
The development of design methods has been closely associated with prescriptions for a systematic process of designing. These process models usually comprise a number of phases or stages, beginning with a statement or recognition of a problem or a need for a new design and culminating in a finalised solution proposal.
These simplified figures are often based on a set of rules. The basic shape according to White (1984) can be characterized in terms of "elegance, clarity, ease, pattern, simplicity, and validity". [4] Elegance is basically determined by whether or not the diagram is "the simplest and most fitting solution to a problem". [6]
