In a many-to-many relationship, a row in table A can have many matching rows in table B, and vice versa. You create such a relationship by defining a third table that is called a junction table. The primary key of the junction table consists of the foreign keys from both table A and table B.

By creating two one-to-many relationships with a junction table. What is the term for a field in a related database table that refers to the primary key in the primary table? foreign key.

Term. relational database. Definition. A database that contains multiple tables related through common fields.

Answer: a. Query: This is data resulting from questions you ask of one or more tables.

Common Database Data Types

• Integer – is a whole number that can have a positive, negative or zero value.
• Character – refers to any number, letter, space or symbol that can be entered in a computer.
• String – is used to represent text.
• Floating Point Number – is a number that contains decimals.

Data types

• String (or str or text). Used for a combination of any characters that appear on a keyboard, such as letters, numbers and symbols.
• Character (or char). Used for single letters.
• Integer (or int). Used for whole numbers.
• Float (or Real).
• Boolean (or bool).

Database Storage. The purpose of every database is to store information, texts, images, even media files. All dynamic modern websites rely on one or more databases for storing articles and other published content, information about the users, contact information, connections to other websites, ads, etc.

Common examples of data types

• Boolean (e.g., True or False)
• Character (e.g., a)
• Date (e.g., 03/01/2016)
• Double (e.g., 1.79769313486232E308)
• Floating-point number (e.g., 1.234)
• Integer (e.g., 1234)
• Long (e.g., 123456789)
• Short (e.g., 0)

In computer science and computer programming, a data type or simply type is an attribute of data which tells the compiler or interpreter how the programmer intends to use the data. A data type provides a set of values from which an expression (i.e. variable, function, etc.) may take its values.

A ‘Real’ data type is numerical data which contains decimal numbers. It would be used when extra detail is required and a whole number would not provide enough information.

Introduction to Data Types. Categorical Data (Nominal, Ordinal) Numerical Data (Discrete, Continuous, Interval, Ratio)

4 Types of Data: Nominal, Ordinal, Discrete, Continuous.

When working with statistics, it’s important to recognize the different types of data: numerical (discrete and continuous), categorical, and ordinal. Data are the actual pieces of information that you collect through your study. Most data fall into one of two groups: numerical or categorical.

Qualitative data is of two types, namely; nominal data and ordinal data. Qualitative data sometimes takes up numeric values but doesn’t have numeric properties. This is a common case in ordinal data.

There are Three Types of Data

• Short-term data. This is typically transactional data.
• Long-term data. One of the best examples of this type of data is certification or accreditation data.
• Useless data. Alas, too much of our databases are filled with truly useless data.

Three key types of analytics businesses use are descriptive analytics, what has happened in a business; predictive analytics, what could happen; and prescriptive analytics, what should happen.

Aristotle figured there were three kinds of friendships:

• Friendships of utility: exist between you and someone who is useful to you in some way.
