The "Berlin Zoo" needs an administrative database for its animals...

The "Berlin Zoo" needs an administrative database for its animals and installations. The management asks you for help with the conception of the database and provide you with the following facts:

  Animals have a name, exactly one species (for example, white rhinoceros, co- atis, wood giraffe, etc.) and a weight

  E.g. there are 4 coatis in the zoo at the moment

  Employees take care for many animals

  Employees have a first and last name, an entry date and working partial or full

time (other working time models are not possible)

  Animals are always cared by several employees

  Animals need food (e.g., wheat, apples, pears, grass, leaves)

  Food has a name and a description

  Animals are always housed in only one enclosure

  Enclosures can't be used over the full year due to yearly modification/renovation

work

  Enclosures have a size, height and surface

Edit the following task with the help of a modelling tool:

a) Create the physical Block Diagram (ERM) b) Create the table (short) description
