LOGICAL MODEL:

The logical model describes the flow of transactional details in the business process. It describes

the flow of information between the various tables in the apartment Services. There are four

primary tables in the database. The initial table is that table with tenant information. The primary

key is the name. All the information that is collected when tenant gives the information is

collected in this table. The table also has the secondary key in the Uber database. The Uber

database stores the tenant information and matches the persons query with AMS aviation website

database. AMS aviation website has a collection of booking details and payment details that is



based on the tenant or owner of flat and AMS database. AMS database has a collection of all the

field that are in customer table, AMS website information table and Aviation Companies table.

Data Flow Diagrams:

The Data flow Diagram below explains the way in which AMS Services, provides its new

service of automatic payment, alerts, problem solving, lease registration etc.

The following is the data flow diagram that shows the flow of information on level one.



Data Dictionary:

Data dictionary is the collection in all the fields that are in the databases and what information

they hold. It is a collection of various data types, the formats, data lengths, optional, its



description and also has an example that explains the particular field



Use Case Diagram:

Use case diagram is a pictorial representation of the process from the process tank perspective.

The above picture depicts tenant at the one end of the pool and in the middle is the process pool.

The AMS service provider and the owner on the other side of the pool. It gives the overview of

the user requirements in a chronological fashion. It shows the interaction between all the actors

and the relationship between the use cases and the users.



Here the tenant creates a use case of query. The query use case gives rise to website use case and

it in turn gives rise to AMS database use case. The tenant interacts with website. The information

is updated in the AMS website by the owner stating his flat is for rent or sale. The AMS database

is also updated at the same time and AMS service provider is updated with the details. AMS

service provider then updates the information to AMS database and tenant updates the

information in to the payment user case.
