A multivalued attribute in Computer Science is an attribute that can have more than one value associated with the key of an entity. For example, in a large company, the divisions can be classified as multivalued attributes of the company entity, as there can be multiple divisions in different...
the foundation of computers and Database Design.The key points in these slide are:Multivalued Dependencies, Functional Dependency, Domain and Range, Set of Possible Values, Full Constraint, Sets of Attributes, Tuple-Generating Dependency, Embedded Constraint, Lossless-Join Decomposition, Split of ...
A new inference rule for embedded multivalued dependencies is presented and the following results about membership problems are shown. Let U be a set of attributes and let W n … W 0 U. Let D = F ∪ E ∪ E 1 ∪…∪ E n, where 1. (i) F is a set of functional dependencies Y...
Can I use if statement in a table valued function? Can I use LEN or DATALENGTH in a WHERE clause? Can I use OUTER JOIN on 2 columns at the same time? Can row_number() work in UNION STATEMENTS ? Can someone explain just exactly why xp_cmdshell is such a massive risk?! Can SQL...

We describe an algorithm to test whether a multivalued dependency is implied by a set of functional and join dependencies. The worst case running time of the algorithm is O ( nm ), where n is the length of the input and m is the number of the attributes in the universe. We also ...
F-Rep represents shapes in n-D space as single real-valued functions f (x1,…,xn). By definition, points with a function result above zero are inside the object, a value equal to zero indicates the border, called isosurface; values below zero define the outside of the object. This ...
Compare each attribute pairwise in its hierarchy level and measure them on a qualitative and quantitative numerical scale (1/9: least valued to 9/9: most important); Calculate the weights of each attribute and place them in a comparison attribute matrix; Determine the final comparison weight of...
