Create an ERD using Lucid Chart for the following description. Be sure to include all necessary entities, attributes, and correct cardinality in relationships between entities. Dont forget foreign keys.

Specifications You have been asked to build a database for a technology company called TechNow. The company owner needs to keep track of the customers that buy their products, the employees that work at TechNow, the offices that the employees use, the vendors that provide them with products, and the products themselves. Each vendor may interact with several employee representatives and requires this support. Employees in their first year usually dont have vendors to support, as they are learning the ropes, but as they work there longer and more vendors are reached, they may be assigned their only vendor. The owner wants to track employee names and email addresses, as well as vendor names and locations. Each employee works only in their own private office at TechNow. Some offices are vacant. Vendors provide products to TechNow, like hard drives, desktop cases, and power sources. Each product they sell comes from only one vendor. Some products are made in house, but if a vendor is in the system they must have provided a product. The owner wants to track product names and each products unique SKU. Finally, enterprise customers purchase products from TechNow and the data from the transactions needs to be recorded. Each product is often purchased by lots of customers, especially if it is popular. Customers are only put in the system if they have made a purchase, but a product does not need to have been purchased to be stored. The owner wants to keep track of customer names and email addresses.

Is this correct? Entities, relationships, cardinalities, foreign keys?
