The Chapter first reviews existing distributed programming languages including Java, Python, Go, Erlang, and Scala, which are selected for comparison with Spatial Grasp Language (SGL), the key component of the chosen for this book Spatial Grasp Technology, as SGL is fundamentally oriented on distributed programming too. After providing summary of the full SGL syntax, it describes in detail the full repertoire of SGL components and their usage, which include constants, variables and universal rules. Then compares SGL with other languages by explaining their similarity and differences, and concludes the Chapter with confirmation of SGL suitability for highly integral and holistic solutions in any distributed spaces.
