A XYZ-star hotel requires a computerized system to automize its front office operations
that support the following functionalities:
 Easy input facility for new data
 Keep details about rooms, tariff, details of occupied rooms, details of unoccupied rooms, check-in
/ check-out timings, staff etc..
 Update necessary details about the room-billing, extra facilities used like gym, laundry,
STD/ISD calls made etc.
 Query support
 Report generation
Perform the following tasks:
(i) Draw the ER diagram by identifying the entities, relationships and cardinality by using
any of the drawing tools like smartdraw, dia, visio, conceptdraw etc.. Follow proper
conventions.
(ii) Create suitable database to support/accommodate all the functionalities referred above.
(iii) Using MS-Access, design various forms to support the hotels’ front office operations such as enquiry form, tariff, categories of rooms along with their category, list of vacant rooms, list of occupied rooms, list of unoccupied rooms, room-billing (which includes extra facilities also), restaurant billing, staff details, list of phone numbers, reservations etc..
(iv) Report generation like daily reports of list of vacant rooms, list of occupied rooms, onduty staff list, list of room reservations made etc.

It appears that you're seeking assistance with a fairly extensive task involving designing an ER diagram, creating a suitable database, and designing various forms and reports for a hotel's front office operations using Microsoft Access. While I can guide you through the process and provide you with an overview of how to approach each step, it's important to note that your question is quite detailed and would require a significant amount of space to provide a thorough response. I'll do my best to provide a concise overview and guidance for each step, but keep in mind that this is a high-level explanation.

Before we begin, let's break down the tasks you've mentioned:

1. ER Diagram: An Entity-Relationship (ER) diagram is a visual representation of the entities (objects) in a system, their relationships, and the attributes associated with them. The conventions typically used in ER diagrams include:

   • Entities (e.g., Room, Guest, Staff, Billing, Reservation)
   • Relationships (e.g., Occupies, Provides, Uses)
   • Cardinality (one-to-one, one-to-many, many-to-many)

   You would need to identify the various entities, their attributes, and how they are related to each other.

2. Database Design: Based on the ER diagram, you would design the structure of the database. This involves creating tables to store data, defining relationships between tables, and specifying constraints.

3. Creating Forms: Forms in Microsoft Access allow users to input and view data. You'll need to design forms that correspond to the functionalities you mentioned, such as enquiry, tariff, room lists, billing, staff details, etc.

4. Report Generation: Reports provide formatted views of data, typically for printing or sharing. You would design reports to generate the desired information, such as daily lists of vacant rooms, occupied rooms, staff lists, etc.

Let's briefly touch upon each step:

(i) ER Diagram: To create the ER diagram, follow these steps:

1. Identify Entities: Start by listing the entities involved in the hotel's front office operations. For example, Room, Guest, Staff, Reservation, Billing, Extra Facilities, etc.
