What is the difference between associative entity and relationship with attribute?
Wiki User
∙ 12y ago
A relationship with attributes should be an associative entity when:
- All relationships for the associative entity should be many
- The associative entity could have meaning independent of the other entities
- The associative entity should have attribute(s), but it may or may not have an identifier
- The associative entity may participate in other relationships other than the entities of the associated relationship
- Ternary relationships should be converted to associative entities

An associative entity is used to represent a many-to-many relationship between two or more entities in a database, while a relationship with attribute represents additional information or properties about the relationship itself. In other words, an associative entity helps in resolving many-to-many relationships, while a relationship with attribute adds details about the connections between entities.

What is difference between primary key and foreign key?
A primary key is an attribute (or combination of attributes) that uniquely identifies each row in a relation. A primary key is designated by underlining the attribute name. The primary key of an entity set allows us to distinguish among the various entities of the set. A foreign key is an attribute in a relation of database that serves as the primary key of another relation in the same database.
Differences between metadata and attribute data?
Metadata describes the characteristics of data, such as its format, source, and creation date, while attribute data provides specific values and properties of the data, such as the size, color, or location. Metadata is essentially data about the data, providing context and information on how to interpret and use the data, while attribute data is the actual content or values within the dataset.
Discuss the difference between a composite key and a composite attribute.How would each be indicated in an ERD?
Attribute is the property of entity.The composite attribute is like address(where street no,house no,town name all include).Composite key is also an attribute,but only which attribute are work as a unique identifier. Example:> In an ERD if vendor placed with orders then order(order day, order number) vendor(vendor code,vendor address) Here, order and vendor both are entity and order number, vendor code both are Composite key(because those are unique)but vendor address is a Composite attribute and order day(may be not unique)is an attribute only. So, we can conclude that all attribute not Composite key.
What is the difference between data and data element?
Data refers to raw facts and figures, while a data element is a unique unit of data that represents a specific attribute or characteristic. Data elements are used as building blocks to organize and structure data within a database or system.
What is data dependency in DBMS?
Data dependency in DBMS refers to the relationship between different data elements within a database. There are three main types: functional dependency (one attribute determines another), partial dependency (part of a composite key determines other attributes), and transitive dependency (dependency between non-key attributes). Understanding data dependencies is crucial for database normalization and maintaining data integrity.

Difference between partial dependency and fully functional dependency?
The difference is that partial dependency is when a database's attribute is only partially dependent on the primary key. Fully functional dependency is when the attribute is entirely dependent on the key.
