An attribute of a binary relationship type can be migrated to become an attribute of one of the participating entity types.

The attributes of 1:1 or 1:N relationship types can be migrated to one of the participating entity types. In case of 1:1 cardinality, attribute can be moved to either of entity types in binary relationship and in case of 1:N cardinality attributes can be migrated only to N side of relationship. In both 1:1 and I:N relationship types, the decision as to where a relationship attribute should be placed-as a relationship type attribute or as an attribute of a participating entity type-is determined subjectively by the schema designer. For relationship types with cardinality M:N, attributes cannot be migrated to become attributes of one of participating entity types.

The two alternatives for specifying structural constraints on relationship types.

The two alternatives for specifying structural constraints on relationship types are the cardinality ratio and participation constraints.

Cardinality ratio: The cardinality ratio for a binary relationship specifies the maximum number of relationship instances that an entity can participate in. For example, in the WORKS_FOR binary relationship type, DEPARTMENT: EMPLOYEE is of cardinality ratio l:N, meaning that each department can be related to (that is, employs) any number of employees, but an employee can be related to (work for) only one department. The possible cardinality ratios for binary relationship types are 1:1, l:N, N:l, and M:N.

Participation constraint: The participation constraint specifies whether the existence of an entity depends on its being related to another entity via the relationship type. This constraint specifies the minimum number of relationship instances that each entity can participate in, and is sometimes called the minimum cardinality constraint. There are two types of participation constraints-total and partial.

How To Install a Husband?

INSTALLING A HUSBAND

Dear Tech Support,

Last year I upgraded from Boyfriend 5.0 to Husband 1.0 and noticed a distinct slow down in overall system performance -- particularly in the flower and jeweler applications, which operated flawlessly under Boyfriend
5.0.

In addition, Husband 1.0 uninstalled many other valuable programs, such as Romance 9.5 and Personal Attention 6.5 and then installed undesirable programs such as Premier League 5.0, Six Nations 3.0, and Golf Clubs 4.1.

Conversation 8.0 no longer runs, and Housecleaning 2.6 simply crashes the system. I've tried running Nagging 5.3 to fix these problems, but to no avail.

What can I do?

Signed,

Desperate.


____________ _________ ___


Dear Desperate,

First keep in mind, Boyfriend 5.0 is an Entertainment Package, while Husband 1.0 is an Operating System.

Please enter the command: 'HTTP: I Thought You Loved Me.html' and try to download Tears 6.2 and don't forget to install the Guilt 3.0 update. If that application works as designed, Husband 1.0 should then automatically run the applications Jeweler 2.0 and Flowers 3.5.

But remember, overuse of the above application can cause Husband 1.0 to default to Grumpy Silence 2.5, Happy Hour 7.0 or Beer 6.1.

Beer 6.1 is a very bad program that will download the Snoring Loudly Beta.

Whatever you do, DO NOT install Mother-in-law 1.0 (it runs a virus in the background that will eventually seize control of all your system resources).

Also, do not attempt to reinstall the Boyfriend 5.0 program. These are unsupported applications and will crash Husband 1.0.

In summary, Husband 1.0 is a great program, but it does have limited memory and cannot learn new applications quickly. You might consider buying additional software to improve memory and performance.

We recommend Food 3.0.

HOPE THIS WORKS !!!!

The two alternatives for specifying structural constraints on relationship types.

The two alternatives for specifying structural constraints on relationship types are the cardinality ratio and participation constraints.

  • Cardinality ratio: The cardinality ratio for a binary relationship specifies the maximum number of relationship instances that an entity can participate in. For example, in the WORKS_FOR binary relationship type, DEPARTMENT: EMPLOYEE is of cardinality ratio l:N, meaning that each department can be related to (that is, employs) any number of employees, but an employee can be related to (work for) only one department. The possible cardinality ratios for binary relationship types are 1:1, l:N, N:l, and M:N.
  • Participation constraint: The participation constraint specifies whether the existence of an entity depends on its being related to another entity via the relationship type. This constraint specifies the minimum number of relationship instances that each entity can participate in, and is sometimes called the minimum cardinality constraint. There are two types of participation constraints-total and partial.

What is a participation role?

Participation role signifies role that a participating entity from the entity type plays in each relationship instance, and helps to explain that relationship means. Using Role name is not necessary in the description of relationship types where all participating entities are distinct because in such case name of entity types generally specify the role played by each entity type. But when one entity type participate in a relation in more than one role; recursive relationship; it becomes necessary to use role names in the description of relationship type.

The differences among a relationship instance, a relationship type, and a relationship set.

A relationship type R among n entity types E1, E2, …, En is a set of associations among entities from these types. Actually, R is a set of relationship instances ri where each ri is an n-tuple of entities (e1, e2, …, en), and each entity ej in ri is a member of entity type Ej, 1≤j≤n. Hence, a relationship type is a mathematical relation on E1, E2, …, En, or alternatively it can be defined as a subset of the Cartesian product E1x E2x … xEn . Here, entity types E1, E2, …, En defines a set of relationship, called relationship sets.

The difference between an attribute and a value set.

An attribute is a property that describes an real world entity. Now for all entities there are certain values that each attribute can take. Set of all values that an attribute can take is called value set. Often the value that attribute take are lesser in number than number of element in value set. Difference between an attribute and value set can simply be taken as that between a variable and group of values that this variable can take. For example for a person an attribute can be name. For value of this attribute we can have any combination of character string so that will be the domain but in reality not all combination of characters exist as name of person.

Differences among an entity, an entity type, and an entity set.

A set of entities that have the same attributes is called an entity type. Each entity type in the database is described by a name and a list of attributes. For example an entity employee is an entity type that has Name, Age and Salary attributes.
The individual entities of a particular entity type are grouped into a collection or entity set, which is also called the extension of the entity type.
An entity is a thing in the real world. It may be an object with a physical existence or an object with a conceptual existence. A set of these entities having same attributes is entity type and collection of individual entity type is an entity set.
