What are the types of relationships used in Database modeling?
In database modeling, the primary types of relationships are one-to-one, one-to-many, and many-to-many. A one-to-one relationship means a single record in one table is linked to a single record in another table. A one-to-many relationship allows a single record in one table to be associated with multiple records in another table. Lastly, a many-to-many relationship occurs when multiple records in one table relate to multiple records in another, often necessitating a junction table to manage the associations.

Is database software or hardware?
A database is an integrated collection of logically related records or files which consolidates records into a common pool of data records that provides data for many applications. A database is a collection of information that is organized so that it can easily be accessed, managed, and updated
What is the difference between relationship type and relationship instance in database?
In a database, a relationship type defines the abstract structure and constraints of how entities are related, including cardinality and participation rules. In contrast, a relationship instance represents a specific occurrence of that relationship type, linking actual records in the database. Essentially, the relationship type serves as a blueprint, while the relationship instance is the tangible connection between entities in the data.
What kind of relationship describes when a record from one table is related to several records in another table?
The relationship that describes when a record from one table is related to several records in another table is called a "one-to-many" relationship. In this scenario, a single record in the first table can be associated with multiple records in the second table, while each record in the second table is linked to only one record in the first table. This type of relationship is commonly used in database design to represent hierarchical data structures.
What is the order of records stored in a database in Access?
Records are stored in order of the primary key, unless you specify another sorted order.
What is database composition in database?
Composition is a term that comes from object oriented design. It is a relationship in which a number of parts comprise a whole, and these parts can only be part of one whole. There is no direct translation of this concept to database design, but there are some situations in the database world that represent the concept of composition. Field to record A record is composed of fields and these fields are part of only one record. When the record is removed, the fields are also removed. So, each field has a composition relation with its record. This means that when you store a collection (a comma separated list of names for example) in a database field, this is in fact a composition relationship. Record to record from other table If you want to create a composition relation between records from a table A and records from another table B, where A is the whole and B the parts you must ensure that 1. There is a one-to-many relationship between table A and B. This is done by adding a foreign key to table B. 2. That all part records in B are deleted when the whole record in table A is deleted. This can be done by setting ON DELETE CACADE on the foreign key relationship. 3. That the records in table B don't become part of another composition relationship. But this restriction cannot be enforced by the database to my knowledge.
Database is a collection of related records?
YES, Database is a collection of related records.
What is a derived database?
