DEFINING THE MYNET RELATIONAL SCHEMA

+ TRANSFORMATION RULES UML – RELATIONAL(1)1. Create a relation schema for each class with the attributes

and using the identifier as primary key

2. Examine (1,1) associations, for each one proceed as follows: Let R be an association between classes A B integrate in the relation

schema representing A the key of B. The transformation of R is terminated

7+ A(1,1) --- B

POST (postID: Integer, timeStamp: Date, geoStamp: String, contentID: Integer)

CONTENT( contentID: Integer, text: String)

+ TRANSFORMATION RULES UML – RELATIONAL(2)3. Examine associations with cardinality (0,1). For each one

proceed as follows: Let R be an association between classes A(0,1)--- B with cardinality

(0,1) in A Add as foreign key the key of A in B

The transformation of R is terminated

9+ A(0,1)--- B

CONTACT ( contactID: Integer, lastName: String, givenName: String, society : String)

BASICINFO ( socialNetworkID: URI, webSite: URI, contactID: Integer)

POST (postID: Integer, timeStamp: Date, geoStamp: String, contactID: Integer, contentID: Integer)

10+ A(0,1)--- B

BASICINFO ( socialNetworkID: URI, webSite: URI)

ADDRESS (street: String, number: Integer, city: String, ZipCode: String, socialNetworkID: URI)

EMAIL ( email: String, type: String, socialNetworkID: URI)

LANGUAGE (languageID: Integer, Language: String, socialNetworkID: URI)

+ TRANSFORMATION RULES UML – RELATIONAL(3)4. Examine associations with cardinality (x,n). For each one

proceed as follows: Let R be an association between classes A(x,n)--- B. Create a table

with: R attributes The key of A and B

The transformation of R is terminated
