Manga Data Bases, comic style learning.

To be honest, reading the Database descriptions in the manga comic style reminded me of trying to figure out the stupid data book when I worked in retail. This is because the comic tries to simplify the way you make databases through a chart to figure things out fast, and it uses the retail grocery setting as an example. While the data is suppose to help the cashier quickly find the price of items, I got confused on how things are recorded and joined from other data to become one data. This also confused me in a real setting of looking at a book to figure out what a specific type of jacket would cost, because where i worked, you would have to go to the outdoor wear tab then go on the chart to find either adult or kids, then scan the chart to either men or women, then scan again for either workout, heavy, medium, or light wear. Then if the jacket was of brand name, if you even knew the brand names, then you would repeat the process on another page the chart tells you to go to in order to figure out what the brand and style of jacket would cost. Overall it was nice to read a description in manga style, but reading about databases in chart style just made me confused and took me to the time when I worked in retail.
