Database description

The database will be created on Ionic Storage. Ionic Storage should use SQLite as its driver on Android and iOS devices.

List of Storage keys

Area :

• area : the list of areas
• type : the list of area types

Operation :

• operation
• vegetable
• vegetableName
• supplier (implements NamedDbObject)
• category : categories of vegetables (implements NamedDbObject)
• done : if the operation is done or not

Modalities :

• label (implements NamedDbObject)
• sublabel
• modality

Note : NamedDbObject has a name and an id; it allows us to reduce code repetitions by using a single method instead of 3 to interact with suppliers, labels and categories in the database respectively.
