Designing an ERD

Design (ERD) to model the above scenario. Identify the different entities and attributes for each entity. Suggest and justify the choice of relationship and cardinality of the relationship
Scenario:

Muscat Agro Products is one of the leading vegetables suppliers in Oman, which sells various types of vegetables to the various types of customers like super markets, vegetables and fruits shops, hyper markets, hostels, catering companies, restaurants etc. The company has the head office in central market Al-Mawalah, Muscat. The Company intends to automate the process of imports and local purchases, sales and delivery, accounts and administration. Company has many distribution lines with different types of vehicles like pickups, 3-ton trucks, 10-ton trucks and containers. Company has many employees like managers, sales managers, accounts managers, supervisors, truck drivers, loaders, helpers and administrative staff. For the company logistic management is a priority since the vegetables have short shelf life. The overall automation process may result in a very huge database of both structured and unstructured data, which, may need frequent updates. This sort of data may also be considered as big data.

Consider you are responsible to carry out a study of the requirements of registering customers and vegetable sales; suggest a possible solution of designing such a database. Propose a conceptual model, a database management system and related security measures in-line with system data management. You can make relevant assumptions required to formulate business rules, security, and administration.
