I detta arbete undersöks det hur en NoSQL-databas presterar jämfört med en relationsdatabas när kommunikation sker med en webbapplikation. Testning sker med hjälp av en PHP-applikation och Ajax för att simulera användningen av en webbapplikation. Den data som kommer lagras i databaserna kommer vara strukturerad och databaserna kommer vara på ett odistribuerat system. Metoden är teknikorienterade experiment men för framtida arbeten kan dessa tester utföras som en fallstudie för att ytterligare simulera en skarp användning av en webbapplikation.I detta arbete förklaras anledningen till framtagningen av NoSQL-databaser. Saker som diskussionen om att NoSQL kommer ta över platsen som de mest använda databaserna från relationsdatabaser tas också upp. Förhoppningsvis kan detta arbete ge viss insikt till den diskussionen.Resultatet av detta arbete visar att NoSQL kan passa bra för databaser som har en last som ärskriv- och uppdateringstung, men också att relationsdatabaser fortfarande passar bra i många fall.
Background: Overweight and obesity is a public health problem that is spreading in our society. Being greatly discussed and researched there is new methods being developed constantly in an attempt to hinder the spreading. The vast amount of different training programs and diets can seem endless. In this literature review a form of training, resistance training, is examined if it can be a method of hindering the spread of overweight and obesity. Aim: The aim of this literature review is to describe the effect of resistance training as a mean to achieve weight loss. The effect of both resistance training alone and resistance training combined with aerobic training and changed dietary habits will be described. Method: The method is a literature review where previous research is examined to achieve the aim of this literature review. Results: In some few articles there was no sign of any effect on weight loss using resistance training, although, in the majority of the articles there were positive results, often equal those of the more popular forms of training such as aerobic training. The best results for the cause of achieving weight loss were shown when resistance training was combined with aerobic training and changed dietary habits. These results were however only marginally better than when the different methods of training were performed individually. Conclusion: Resistance training as a mean to achieve weight loss is often equal to theuse of aerobic training, which is one of the more popular methods of training to achieve weight loss.The greatest effect is given if these training methods are combined with each other and with changed dietary habits. Combining aerobic training with resistance training can be a strong complement to break a monotonous training habit and increasing the motivation.
