What is database? A database can be defined as a collection of coherent,meaningful data.The phrase collection of coherent data needs to have a point of reference to be understood.A simple point of reference to be understood.A simple point of reference would be the example of a postal address this would generally contain
 * 1) 1.A building name
 * 2) 2.A road name
 * 3) 3.A flat number in the building
 * 4) 4.An area name
 * 5) 5.A state name
 * 6) 6.A pin code
 * 7) 7.A country name(This is optional, but necessary if the letter is destined to a foreign country)

To understand project on this further,multiple address kept together in one place,such as an address book,could be termed as a coherent collection of data base.Thus the Address book is adatabase and the postal address in the book,is the data that fills the database.

What is a SQL join? A SQL join is a Structured Query Language (SQL) instruction to combine data from two sets of data (i.e. two tables). Before we dive into the details of a SQL join, let’s briefly discuss what SQL is, and why someone would want to perform a SQL join.

SQL is a special-purpose programming language designed for managing information in a relational database management system (RDBMS). The word relational here is key; it specifies that the database management system is organized in such a way that there are clear relations defined between different sets of data.

Typically, you need to extract, transform, and load data into your RDBMS before you’re able to manage it using SQL, which you can accomplish by using a tool like Stitch.
