SQL
SQL stands for Structured Query Language, is a form of communication that uses queries structured in a specific format to store, manage & retrieve data from a relational database.
Queries
A query is a type of computer programming language that is used to retrieve data from a database. Databases are useful in a variety of ways. They enable the retrieval of records or parts of records, as well as the performance of various calculations prior to displaying the results. A search query is one type of query that many people perform several times per day. A search query is executed every time you use a search engine to find something. When you press the Enter key, the keywords are sent to the search engine, where they are processed by an algorithm that retrieves related results from the search index. Your query's results are displayed on a search engine results page, or SER.
Write down 5 triggers. Triggers should be meaningful.

- To vary your reporting, you decided to include graphical representation. Create a clustered column chart that shows the total amount each active customer with a data plan must pay. Format the total pay column to currency and give the chart an appropriate title. Remember to label the axes. (Hint: Create a query and export it to a spreadsheet application to create the chart.) Ensure that the chart is labelled appropriately and is placed on a new sheet. Name the Spreadsheet as MGMT2006_G#_<first name last name>. For example, MGMT2006_G50_ Jane Doe.Answer it.

The dealership sells both new and used cars, and it operates a service facility. Base your design on the following business rules: A salesperson may sell many cars, but each car is sold by only one salesperson. A customer may buy many cars, but each car is bought by only one customer. A salesperson writes a single invoice for each car he or she sells. A customer gets an invoice for each car he or she buys. A customer may come in just to have his or her car serviced; that is, a customer need not buy a car to be classified as a customer. When a customer takes one or more cars in for repair or service, one service ticket is written for each car. The car dealership maintains a service history for each of the cars serviced. The service records are referenced by the car’s serial number. A car brought in for service can be worked on by many mechanics, and each mechanic may work on many cars. A car that is…
