The entities and attributes should be based off a travel website like Expedia but this below is just an example
example, a project has invoices, invoice distributions, and suppliers as nouns. These nouns are entities, or tables, that would be used to create the E-R model. Then, the adjectives and verbs that describe the nouns would become the attributes, or columns.
For my Travel website design five entities and some attributes that describe the entities. Do not exceed more than five attributes for each entity.
In a Microsoft Excel spreadsheet, define six columns (nouns) to design a database. These will be the tables for your database. In the rows for each column, define the attributes (adjectives).
This is a example of how I want my spread sheet to look, we might have the following entities and attributes:
INVOICES INVOICE_DISTRIBUTIONS SUPPLIERS
# Invoice_id # Invoice_distribution_id # Supplier_id
Invoice_num Invoice_distribution_line_num Name
Invoice_type Line_type Address
Supplier_id Invoice_id
the nouns and adjectives you identified into will help to form a logical model-the E-R model.
