IGCSE ICT (0417) June 2024 P21 Database

Summary

In this video, the speaker demonstrates how to complete the Cambridge IGCSE ICT Paper 2 Database Task for May/June 2024 (Variant 21). Using Microsoft Access, the task involves importing CSV files, setting up primary keys, and modifying data types. Key steps include creating relationships between tables, designing queries for reports, building forms for data entry, and implementing radio buttons for user selection. The speaker walks through each step, showing how to work with tables, add records, and apply automated selection methods, while capturing evidence through screenshots to document each part of the process.

Takeaways

• 😀 Start by creating a new database in Microsoft Access, and give it an appropriate name.
• 😀 Import a CSV file (e.g., 'child.csv') into the database, ensuring the first row contains field names.
• 😀 Choose 'Child ID' as the primary key when importing the 'child.csv' file.
• 😀 Set appropriate data types for each field (e.g., text, date/time, Boolean) and adjust the format where needed (e.g., 'dmy' for contact numbers).
• 😀 Take a screenshot of the table design, ensuring the primary key symbol is visible, to include in the evidence document.
• 😀 Import the 'bookings.csv' file using the same method and set appropriate field names and data types.
• 😀 Create a one-to-many relationship between the 'Child ID' fields in the 'child' and 'booking' tables using the database tools.
• 😀 Generate a query to display specific fields from both the 'child' and 'booking' tables, applying necessary formulas like 'Total Time'.
• 😀 Create a column-based data entry form for the 'child' table, including fields like 'First Name', 'Last Name', and 'Food Allergy'.
• 😀 Implement radio buttons within the form to allow users to select options like 'Ailment ID' and ensure all labels are aligned correctly.
• 😀 Add a new record to the child table using the form and demonstrate how to locate the record via an automated selection method based on 'Child ID'.

Q & A

What is the first step in creating a database in Microsoft Access as described in the script?

The first step is to create a blank database in Microsoft Access by selecting 'Blank Database,' giving it an appropriate name, and then creating the database.

How do you import a CSV file into Microsoft Access?

To import a CSV file, go to 'External Data,' select 'New Data Source' from the file option, then choose the CSV file from your folder. Select 'First Row Contains Field Names' and proceed with the import.

What primary key is chosen for the 'child' table in the script?

The primary key chosen for the 'child' table is 'Child ID,' which is selected during the import process.

How do you set the data types for fields in a table in Microsoft Access?

To set the data types, you click on the 'Advanced' button after selecting the fields. Then, for each field, you adjust the data type as necessary, such as changing 'Food Allergy' to 'Boolean' and 'Contact Number' to 'Text.'

What is the purpose of setting the 'Food Allergy' field to Boolean in the script?

The 'Food Allergy' field is set to Boolean to represent a yes/no option, indicating whether a child has a food allergy.

What is the relationship between the 'child' and 'booking' tables, and how is it created?

A one-to-many relationship is created between the 'Child ID' fields in both tables. This is done by dragging and dropping the 'Child ID' from one table to the other in the 'Relationships' section.

What is the formula for calculating the total time in the query?

The formula for calculating total time is 'End Time - Start Time * 24,' which is set as a new field in the query.

How is the total time field formatted in the query?

The total time field is formatted as a numeric value with one decimal place to represent the calculated total time.

What does the form created in Step 15 allow users to do?

The form created in Step 15 allows users to enter and view data, such as last name, first name, child ID, and food allergy status, from the 'child' table.

How do you link the grouped radio buttons to the 'Ailment ID' field in the form?

The grouped radio buttons are linked to the 'Ailment ID' field by creating an option group in the form design and assigning the 'Ailment ID' field to store the selected value from the radio buttons.
