Concept explainers

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.

Case 1: Create a use case diagram based for the system that follows. Consider the following Pet Groomers Appointment system: When making a booking, pet owners need to fill a booking form that states their name, address, phone number, and the pets' details such as pet name, breed and age. Owners will also enter their preferred date of appointment such as day and time. The admin receives the booking form and checks the groomer's schedule to see whether the time slot is booked. If the slot is free, the booking is scheduled and confirmation will be given. However, if the slot is booked, the admin will suggest the next available slot based on the day and time entered. If the pet owner agrees, they will confirm the booking and it will be scheduled. An assigned groomer will receive the booking under their schedule. The system will send a reminder to the owner 3 days before their appointment.
