Q & A

What is the main purpose of the video?
-The main purpose of the video is to guide viewers through the process of creating an event calendar with an event report page and an event form page, which allows users to display, modify, and generate new events.
What are the two primary pages created in the event calendar system?
-The two primary pages created are the event report page, which displays data from the database, and the event form page, which allows users to modify existing events and generate new ones.
How does the calendar page interact with the event form page?
-When a user clicks on a date number on the calendar page, the event form page appears, enabling the user to either create a new event or modify an existing one.
What feature allows users to change the date of an event?
-The drag and drop utility allows users to change the date of an event by dragging it to a new date on the calendar.
How does the system handle the time component of the date?
-If the start date or end date columns do not include time components, they will be shown as 12 am. Users can choose to display the time portion of the date by selecting 'Yes' for the Showtime option.
What is the significance of the 'class' column in the event table?
-The 'class' column helps in styling events using different colors, allowing for better visual differentiation and organization of events.
How can users create a new task from within the calendar?
-Users can create a new task by clicking on any empty cell in the calendar, which will open the event form page where they can input the task details.
What happens when a user clicks on an existing entry in the calendar?
-When a user clicks on an existing entry, the event form page opens, allowing the user to access and modify the details of the existing task.
What are the status field options available in the demo task table?
-The status field in the demo task table has four options: open, on hold, pending, and closed, which can be used to indicate the current state of a task.
How does the drag and drop feature affect the database?
-When a task is dragged and dropped to a new date, the date change is reflected in the demo tasks table in the database, updating the event's date accordingly.
Where can viewers find the source code used in the video?
-Viewers can download the source code from the video description, specifically in the 'part 11' folder.

📅 Creating an Event Calendar System

This paragraph introduces the video's objective to create an event calendar system. It involves setting up an event report page to display data from the 'demo tasks' database table and an event form page for modifying existing events and generating new ones. The calendar page is interactive, allowing users to click on a date to bring up the event form and change event dates. The video also promises to cover the creation of a drag-and-drop utility for events, which will update both the calendar display and the database. Initial steps include adding the 'demo tasks' table and its data to the database, followed by downloading the source code provided in the video description.

🔍 Exploring the Event Calendar Pages

The second paragraph delves into the functionality of the event calendar system. It describes how to check the created pages, including the calendar page, event report, and event form pages. The 'supplemental information' property is highlighted to show the user assignment of tasks, while the 'class' column is used for styling events with different colors. The paragraph explains how to create a new task from the calendar and access existing tasks. It also details the process of creating and modifying tasks, including changing task status options in the 'demo task' table. The video concludes with a demonstration of the drag-and-drop feature, which allows users to move events to different dates and see the changes reflected in real-time in the database.

Keywords

💡Event Calendar

An 'Event Calendar' is a digital or physical tool used to organize and display events in chronological order. In the context of the video, it is a key component of the project where the calendar page is created to display and manage events. The script mentions the creation of a calendar page that interacts with other pages to display and modify events.

💡Event Report Page

The 'Event Report Page' is a specific type of interface within the system that displays data from a database, in this case, from the 'demo tasks' table. It is one of the pages created in the video to visualize the events and is integral to the overall event management system being developed.

💡Event Form Page

The 'Event Form Page' is a user interface that allows users to input, modify, or generate new events. It is a crucial part of the video's project, enabling interaction with the event data, such as creating new tasks or changing the date of existing events.

💡Database

A 'Database' is an organized collection of data, typically stored and accessed electronically. In the video, the database is where the 'demo tasks' table and its data are stored, and it is the backend storage for the event calendar system being created.

💡Drag and Drop

The 'Drag and Drop' feature allows users to move items on a graphical interface by clicking and dragging the item to a new location. In the video, this utility is implemented to change the date of an event visually on the calendar and correspondingly update the database.

💡Primary Key

A 'Primary Key' is a unique identifier for a record in a database table. In the context of the video, the primary key value for calendar events is used to uniquely identify each event for the drag and drop functionality, ensuring accurate updates in the database.

💡PL/SQL

PL/SQL is Oracle's procedural language extension to SQL for developing database applications. In the video, PL/SQL code is used to handle the logic for the drag and drop feature and to update the start and end dates of events in the database.

💡Apex

In the context of the video, 'Apex' likely refers to Oracle Application Express (APEX), a low-code development platform for creating web applications. The script mentions 'Apex dollar' which is a substitution variable used within APEX to reference new values in the database.

💡Status Field

The 'Status Field' in a database table is used to indicate the state or condition of a record. In the video, the status field in the 'demo tasks' table has options like 'open', 'on hold', 'pending', and 'closed', which are used to track the progress or status of tasks.

💡Supplemental Information

Supplemental Information provides additional details beyond the primary data. In the video, the 'Supplemental Information' property is mentioned as displaying the name of the user to whom the task is assigned, offering more context about the task's ownership.

💡Class Column

A 'Class Column' in the context of the video is used for applying CSS styles to differentiate and color-code events in the calendar. This helps in visual organization and quick identification of events based on their type or category.
