Join Line
projecting: manipulating data to eliminate columns in a table. Joining: manipulating data to combine two or more tables.
The anserw is 64 people. 6x4=24 5x8=40 24+40=64
its ur six time tables
Doors, windows, tables, books, walls, rooms.
12 tables. There would be 4 persons per table (you lost 2 seats per table as 2 ends must touch to put them together), except for the first and last table that only will have one end touch leaving them with 5 seats per table.

The field in a related table that matches a field in another table is called a foreign key. This foreign key establishes the relationship between the two tables in a database.
In a relational database, the schema defines the tables, the fields in each table, and the relationships between fields and tables.
Referential Integrity is a set of rules that a DBMS (Database management system) follows to ensure that there are matching values in the common field used to create the relationship between related tables and that protects the data in related tables to make sure that data is not accidentally deleted or changed.
A database is made up of related information in Tables and fields.

A common field in a database is the "primary key". It is a unique identifier for each record in a database table and is used to uniquely identify each row. It is typically a numerical value or a combination of values that ensures each record is distinct from all others.
An add query, more commonly known as an Append query, allows you to add records to a table. It can combine data from two tables, reading data into one of the table. There must be compatibility between the tables, like having similar fields. You could have two tables with names and addresses and having corresponding fields. They could then be transferred into the corresponding field. If there are no compatible fields, then it can't be done.An add query, more commonly known as an Append query, allows you to add records to a table.
