salut,
je lis actuellement un livre sur entity framework et je suis amené à étudier un exemple de relation à la fois "est-un" et "a un".
mais je ne comprends pas l'exemple, je précise que le livre est en anglais.
voici le texte :
tout tourne autour du sens de "location" et de "park".Let’s say you have two tables that describe scenic parks and their related locations. In your database, you
represent these with a Location table and a Park table. For the purposes of your application, a park is
simply a type of location. Additionally, a park can have a governing office with a mailing address, which
is also represented in the Location table. A park then is both a derived type of Location and can have a
location that corresponds to the park’s governing office. It is entirely possible that the office is not
located on the grounds of the park. Perhaps several parks share an office in a nearby town. Figure 2-37
shows a database diagram with the Park and Location tables.
j'ai cherché dans un dico, location = emplacement
et car-park = parking ??
une autre chose, c'est "grounds of the park", le sol??
si vous pouvez m'aider pour cette question de langue,
merci!
