1) Create a folder (directory) called "sqlite" (without the quotes) in your base drive (eg. C:\sqlite) 2) Create a Database called "test.db" (without the quotes) in C:\sqlite using Sqlite DBBrowser (Make sure the extension is .db – not .sqlite) 3) In test.db create a table called book. The table should have the following columns: Id - Integer, Not Null, Unique, Primary Key, Auto Increment Author - Text, Not Null Title - Text Not Null Year - Integer, Not Null Price – Real, Not Null - Add some rows with data for the above table.

SQL A table Products have: a name (TEXT) a description (TEXT) a unit cost stored in cents (INTEGER) and of course we also add an id column to identify them. Separately, we'd like to track the number of items in stock for each product. To do so we'll have a store and an inventory table. Stores have just an id and a name. Then, our inventory table should combine stores and products, listing how much of each product each store has in stock. a product_id (INTEGER) a store_id (INTEGER) a quantity (INTEGER) in stock Now we can insert some stores, products and inventory into our database. There are 2 stores -- one called NY and one called NJ. There are 2 products we are concerned with. Their names are sneakers, costing $220 (remember this is dollars!) and boots costing $350. Use any description for each that you'd like. NY has 4 sneakers in stock and 3 boots. NJ has 5 sneakers in stock and no boots. Insert the above data into the tables you have created.

Create an application which can access a database. Create a database with an application user, user specific for your application to use, and 1 table of a couple of fields properly indexed. Grant permissions for the user to access the table. (submit .SQL file) Create a simple application, language of your choice, (BE languages only, no JS or Node) which can do the following operations: (submit source code file): Connect using the application user created above. Insert into the table, and select from the table using a WHERE clause, where all fields are parameterized. Display results of the select. Use a simple web server API interface for data input and output, which can be accessed via local browser or curl.

The symbol table stores the memory address associated with each variable. What is the memory address of the start_time variable in main()? You only need to fill in the last 2 digits of the address. 0x7ffd949d30__ What symbol was added after the data type of MoveSchedule's start_time and end_time parameters? Place a check (✓) beside your answer. int * & start_time What is the memory address of the start_time variable in MoveSchedule()? You only need to fill in the last 2 digits of the address. 0x7ffd949d30__ What happens to the value of the start_time variable in main() when the start_time variable in MoveSchedule is updated? Place a check (✓) beside your answer. start_time in main remains the same start_time in main gets the value assigned to start_time in MoveSchedule start_time in main changes to 0.
Code should be in Python Prompt the user for a title for data. Output the title.Ex: Enter a title for the data: Number of Novels Authored You entered: Number of Novels Authored Prompt the user for the headers of two columns of a table. Output the column headers.Ex: Enter the column 1 header: Author name You entered: Author name Enter the column 2 header: Number of novels You entered: Number of novels Prompt the user for data points. Data points must be in this format: string, int. Store the information before the comma into a string variable and the information after the comma into an integer. The user will enter -1 when they have finished entering data points. Output the data points. Store the string components of the data points in a list of strings. Store the integer components of the data points in a list of integers.Ex: Enter a data point (-1 to stop input): Jane Austen, 6 Data string: Jane Austen Data integer: 6 Perform error checking for the data point entries.
