Through our extensive network of partners, we acquire raw materials from manycountries allowing us to build unique roofs which match our customers rigorous requirements. Ouroffer is all encompassing, including even plants specific to each climate.
These suspended gardens have many advantageous effects, such as reducing energy
consumption, cooling the building and extending the life of the roof. Most importantly, using greenroofs is good for the environment: they negate the damage caused by the widespread use ofconcrete and they reprocess carbon dioxide.
A database that centralizes all the information regarding our companys transport system ,building sites, clients requirements and the current ecological status of their buildings
is useful as it allows us to reduce our carbon footprint.

There are many construction companies aroundthe world. With the advent of climate change and thecountless problems associated with pollution, they areexpanding their product line with more ecologicaloffers. A recent development is roof greening.
Partnering with over 100 companies in Europe,- International is one of the innovators in roofgreening. Our company designs, installs andmaintains roofs. We serve a forward lookingclientele that is concerned with the environment andwants more eco-friendly buildings.

Company Structure
Our multinational company has branches in many countries. In some cities, where ourproducts are very popular, we have more than one branch, each located at a different address.
Branches establish partnerships with other companies that supply materials and fulfilvarious needs. Branches can share partners. The rule of thumb for choosing partners is closestone first as this results in shorter distances travelled and less fuel used; also, less pollution.
Offer and Clients
Green roofs are intensive or extensive. Intensive roofs resemble parks and require severalfeet of ground soil, while extensive ones are suitable for the average home. Because the roofs
are composed from pre-planted modules made of recycled plastics, they are easy to assemble.For each roof requested, we need to know its parameters: soil depth, area, climate, etc.Wealso offer alternative energy sources such as photovoltaic panels.
Clients are either individuals or legal entities. They acquire green points based on theeco-friendliness of the materials requested for their roofs (we know the individualcharacteristics of the materials used a green status and can calculate their cumulative effect).Our clients are rewarded with special discounts and offers depending on the number of greenpoints accumulated.
Projects consist of one or more roofs and, usually, we are required to design, install andmaintain the roof. At the request of our client, we can also inspect the building (using the LEEDStandard) in order to establish the net effect on the environment.

Atransport is the shift of materials between two nodes that are defined by their latitudeand longitude. Through integration with specialized mapping software, we can calculate theactual distances travelled. Anode may be the roof building site, a supplier location, one ofour warehouses, or a route node a map location necessary to completely describe a route(e.g. maritime port, road stop, etc.) Route nodes can be used in conjunction with mathematicalmodels (or algorithms) in order to obtain the most efficient route through a number of givennodes. We always need to know how much of each product is in a node and how much is in transit.
Products are transported in special recyclable containers, tracked by GPS. We know thestate of our products; the containers are capable of maintaining adequate ventilation and otherparameters, such as temperature and humidity, within established optimal ranges.
Each of our branches has several employees responsible with entering data pertaining to the
supply chain. We need to know at all times that our products are in a good condition.
6
Materials, originating in many countries andsupplied by our partners, are transported to thebuilding sites via trucks, planes, ships or rail cars.For each of these, we need to keep track of the waytheir use impacts the environment (fuelconsumption, carbon emissions, etc.)
Regardless of means of conveyance, theenergy consumption depends on various factors,such as: vehicle size, weight (with and without load),configuration, motor power, engine, transmission.,and the slope/gradient of the landscape (plane, hills,mountains), characteristic of each country.

We aim to create a comprehensive database for our green roof company because theneed to catalog, present, and maintain projects and case studies in one central location offersmany benefits not only for our business, but also to researchers, designers, architects, students,public policy people, governments, and the market.
The items in need of resolution, as identified by our conceptual model, are:improving our offer, by making a larger variety of plants and materials available;
identifying and reducing the main factors that have a negative impact on theenvironment (especially those resulting from transport process), by generating reports andstatistics;
keeping track of our raw materials, while they are in transit, by generating periodical
reports about their state and location.

We always have an up to date registry of thetransports scheduled. If we need materials or plantsfrom a specific certain node, we evaluate all theexisting routes passing through it and we choose themost eco-friendly one.
CONTAINER, SHIPMENT. Goods are transported via shipments, each of which contains one
or more containers, which are frequently polled to ascertain their position and internal condition.The data gathered is recorded in CONDITION and GPS POSITION . A shipment is eitherincoming or outgoing (as recorded in its type attribute). Incoming shipments increase theamount of material in a node while outgoing shipments decrease the amount. Shipments may bedelivered directly to a building site (a ROOF) or to a warehouse or supplier location (a NODE).

TRANSPORT UNIT. Depending on the transport type (air, water, ground),we store the parameters relevant to the pollution caused. EC (energyconsumption) is characteristic for each transport unit supplied by a partner.For ships, it also depends on whether it is going upstream or not. For trucks, it is
calculated through a load factor, which varies when the lorry is empty or full.

Generic modell ing
RAW MATERIAL allows various types of parameters to be stored for each material. This makespossible storing photovoltaic cell parameters, as well as plant or material characteristics .
RAW MATERIAL is an entity which contains the formal description of a product. A containermay hold a quantity of one type of goods, as indicated by its relation with RAW MATERIAL.
RAW MATERIAL contains the physical parameters of a product, while GREEN STATUS holdsthe ones that bear on the environmental impact.
The tables below show the manner in which we structure thedata about our materials its manufacturer and its properties.

CLIENT, LOCATION, SITE, ROOF, BUILDING.Clients request the design, construction or maintenanceof roofs, organized in locations, that are owned by theclients. Roofs are then grouped into building sites.Start dates are primary keys because Sites may be(re)opened multiple times.
Clients may also request only inspection of theirbuildings in order to receive LEED certification.
An instance of the SITE entity is a building site fora roof, called ROOF or an inspection site for a building,called BUILDING.
11
CLIMATE, ZONE, SEASON. When designing a roof, we consider the location of the building site.Depending on the climatic conditions, we suggest an appropriate selection of plants to our clients.
Combining information about the products used and the distances traveled, we calculate the eco-friendliness of roofs and projects and quantify it in green points. These measure only the eco-friendliness of the roof, while LEED Certification refers strictly to the whole building.
ROUTE, NODE. We consider transportation as beingalong ROUTEs composed ofNODEs. The latter are origins ordestinations for goods or important waypoints on the map.
The NODE LIST is an intersection entity, in the casethat a node is situated at the intersection of two or more routes.

Assumptions
A transport is considered the shift between a minimum of two nodes. Should the transport usemore than one type of vehicle, we split it into more transports.
The database deals solely with the environmental aspect of the business. The financial andadministrative sides are handled by other databases.
A client is located in the same country as the branch in charge of his sites.
Even though some partners have branches in many countries, we treat each of them separately.
All temperatures are averages calculated over the relevant periods of the previous ten years.
Constraints
Allstar t datesmust be before theend dates.
Longitude and latitude have values between 180E and 180W, and respectively 90N to 90S.ROOF and BUILDING ids are disjoint sets. The same applies to ROOF and NODE.
Gradients represent the slope of the terrain and are measured in degrees.
We use the following measurement units:
depth, altitude: metres
rainfall: litres per square metretemperatures: degrees Celsius
emission factors: g per kWh
Statistics units are recorded thus:
embodied energy: joules
biodegradable, recyclable/ed: true/false
humidity: per cent
speed: kilometres per hour
wind speed: metres per second
area: square metres
energy consumption: kWh
durability: months
CO2 emissions: metric tonnes

It has been a great experience to work ina team and have to analyze and choosepossibilities, create and design conceptualmodels in order to build solutions. None of these
could have been possible, had it not been for thecompetitive atmosphere of creativity encouragedby our principal Mrs. Silvia M.
We have successfully created a databasethat suits the needs of ...International.Using our database, we can obtain statisticsregarding environment and the way ourproducts affect it.
Designing the database was a challenge, aswe had to integrate a large number of entitieswithin the conceptual model.
By studying the problems of theenvironment, we realized the great importanceof pollution and the difficulties people face whentrying to solve them.
