The primary key of a weak entity set is formed by taking the primary key of the strong entity set on which its existence depends (see Mapping Constraints) plus its discriminator. A strong entity set has a primary key. All tuples in the set are distinguishable by that key. A weak entity set has no primary key unless attributes of the strong entity set on which it depends are included. Tuples (a particular row) in a weak entity set are partitioned according to their relationship with tuples in a strong entity set. Tuples within each partition are distinguishable by a discriminator, which is a set of attributes.
A class is a type. An entity is a object created from this type. A class is like a definition and the entity behaves as per this definition.
an entity set may not have sufficient attribute 2 form a primary key is called weak entity set.ex entity set payment has 3 attribute pay-no,pay-date, pay-amount.pay-no is a sequential no generated 4 each loan.each payment entity is distinct,payments 4 different loans may share the same payment no.thus entity set doent have a primary key,so it is a weak entity set.

The characteristic property of the mineral pyrite is sand it is very shiny
no,because physical property is a feature that can be observed and a characteristic property are differrent types of properties<3;)
A referent is a concrete or abstract entity that is used as a point of reference in communication or thought to help convey meaning. It provides context or comparison for understanding the property or characteristic being discussed.
Density is a physical property; physical properties are measurable.
No, energy is not alive. Energy is a property or characteristic of matter that allows it to do work or cause change. Living organisms use energy for various processes, but energy itself is not a living entity.
