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.

Question

In this Assignment, you will build a supermarket product management app that persists data
offline. You will use IndexedDB and Localbase library to read, add, update, and delete products
in the database.
The Product Management App should have the following CRUD features:
1. Create Product: when the user clicks on the create new product button in
figure 1, you should open the add product page in figure 2 that allows the user
to add a new product. Once they click on the save button, you should navigate
them to the product page and show the newly added Product, as shown in figure

Scenario and Database Model: InstantRide InstantRide is the new ride sharing application in the city and it has just started its operations. With the help of the InstantRide mobile application, the users request a ride with their location. Drivers and cars are assigned to the request; and then the driver picks up the user to ride their requested location. Information for the users, drivers and cars are stored in the database as well as the travel transactions. In the USERS table, information for the users are stored with their first name, last name and email: In the DRIVERS table, all the drivers in the InstantRide are stored with their name, driving license number and check and rating information: In the CARS table, all the cars in the InstantRide system are kept with the license plate, model and year: Finally, the transactions of the rides are stored in the TRAVELS table. For each travel, start and end time with location are stored. In addition, the involved driver, car and…
Assignment Create a database in Access. In the database include the following tables: • Student info which has the following fields o First Name o Last Name o StudentID (primary key) • Courses table which includes the following fields: o CourselD (primary key) o Course Name o CRN • Schedule which contains the following fields: o StudentID o CourselD Create the proper relationships between the tables. Fill the tables with at least 5 students and 2 different classes. You can generate the data randomly by using the Mockaroo site Or you can review Extra Material for more links on how to generate random data Create a report to print out the course and the names of the students taking that course (so group by course). Make sure the report is well formatted, looks professional, include a professional header and a footer.
Task 5: The Developers team also wants you to ensure that emails are converted to lowercase after an update operation. Currently, new insertions are guaranteed to have lowercase emails, but there is no such guarantee for legacy emails. Therefore, the team wants to ensure that emails are being retained in a lowercase irrespective of any changes in the database. Create a new TRIGGER called email_update for the USERS table that runs before an UPDATE operation. Task: Create a TRIGGER to run on the USERS table before any UPDATE operation. (SQL Database Test): Create a TRIGGER before any UPDATE operations on the USERS table
Create a new user account with readWrite permission for your database using MongoDB

Computer Science Your task is to build an AJAX search form for this dataset that queries the City of Winnipeg Open Data API and displays search results below the form. Your form should include one or more inputs that correspond to fields within your selected JSON dataset. When the form is submitted you should use the form data to query the Open Data API. Your search should allow users to find a subset of records from a specific dataset. To do this you will be using the WHERE, ORDER and LIMIT capabilities of the Open Data API explained below. Your search form should return anywhere from 0 to a maximum of 100 results. If zero results are found, display a message letting the user know that nothing was found. Only HTML, CSS and Javascript should be used for this portion of the assignment. No PHP code should be used. (Your form will request JSON data from the open data API.)
