SQL stands for Structured Query Language.
SQL is a database management language for relational databases.
SQL lets you access and manipulate databases.
The DBMS provides a set of operations or a language called the data manipulation language (DML) for modification of the data.
Data manipulation can be performed either by typing SQL statements or by using a graphical interface, typically called Query-By-Example (QBE).

An SQL JOIN clause combines columns from one or more tables in a relational database. It creates a set that can be saved as a table or used as it is. A JOIN is a means for combining columns from one (self-table) or more tables by using values common to each.
Constraints are the rules enforced on the data columns of a table. These are used to limit the type of data that can go into a table. This ensures the accuracy and reliability of the data in the database.
Constraints can be divided into following two types:
Column level constraints : limits only column data
Table level constraints : limits whole table data

Tutorial 1: Introduction to Microsoft Access 2007
Learning Objectives
After reading this tutorial and completing the associated exercises, you will be able to:
·
Open MS Access.

Create tables using MS Access.
·
Create forms and use them to enter data into tables.
Note: Be sure to work through the examples in this tutorial as you read. This is the way you will learn by doing.
Microsoft Access: A Relational Database Application
Microsoft Access is a relational database application that is part of the Microsoft Office suite of applications. A database is an organized way to store data, and database software usually provides features that allow a user to add, delete, update, and manipulate (transform) data. A relational database, such as MS Access, stores data in tables. A table consists of rows (records) and columns (fields). Although the appearance of the records and the fields resembles the rows and columns you may have seen or may study later in a Microsoft Excel worksheet, Access is a much more powerful tool than Excel for organizing, storing, and retrieving data. Much of this additional power comes from the relational model that is implemented by MS Access.
With Excel, you can create data tables that list all data for a particular entity (customer, product, etc.) in a row of the worksheet. So, if a customer makes 100 purchases and a business tracks the customer's address in a database, that address would be listed 100 times. The relational model used by MS Access allows us to store data in separate tables and then link tables via common fields—the primary key/foreign key relationship.
A primary key in a table is a field that contains a unique value for each and every record in the table. In other words, if a field is a primary key, you can't use a specific value more than once in that column. A foreign key is a field in one table that contains values that are stored in a primary key in another table. If we look at the foreign key for a specific record, we can use the value to look up more data in the table where that field is used as a primary key. We are then guaranteed to find only one record that matches that value. Basically, a foreign key field provides a reference to a record in another table.
For example, suppose we have a Customer table, in which there is a field CustomerID that is a primary key in that table. If a copy of the CustomerID is stored as a foreign key in a CustomerLoan table, then information such as the customer's address is stored only once, in the Customer table, but can be accessed from any customer loan record. This reduces data redundancy and improves updating and other database functions.
Most of this module will be spent learning by building. First you will create a database consisting of one table, and t.

*
DATABASES AND RELATIONSHIPSA collection of related tables is called a database, or a relational databaseYou connect the records in the separate tables through a common fieldA primary key is a field, or a collection of fields, whose values uniquely identify each record in a tableWhen you include the primary key from one table as a field in a second table to form a relationship between the two tables, it is called a foreign key in the second table
