4.4 Entity Relationship Diagram

In our first entity group we have labelled as customer. Under customer we then have what information we might need from the customer to help our process flow more smoothly. We have their first name, last name, their home address, and as always a number to contact them. All of these different things that I just named off are known as attributes. Like previously mentioned, attributes help us label our customers with some sort of information. With our next entity group we have product. Under product we have the information about the cabin that our customer is interested in renting. In order to know this information we have the cabin that their interested in renting as a cabin number which allows us to narrow everything down to which exact cabin they are staying and all the different descriptions of that cabin. We also have the occupancy of that cabin and the description for other attributes. With our last entity group we have invoice and within invoice we have the cabin number again, description, price, tax, and the total price. With all this different information it helps us better understand our customer. If our customer wants to change something like for instance, which cabin they are wanting to stay in, the only thing we will have to do is pull up their name and all of this information will be listed. 

5.3 Intranet Diagram

As previously mentioned in the last blog of 5.2 talking about the extranet and what was going on inside of it, we then go to the next step and even further into the system. When using the extranet to communicate with Haynes Furniture we were communicating with the "outside network". The intranet is one happens on one side of the VPN like identified above with the pink box. Within intranet we still have a client and also a server. If you didn't notice the client and server are on the same side of the Internet. This is called a client inside the network. Even thought this is an inside network, we still have to get verified through a firewall. The reason for this is because we do not want to take any chances with someone trying to hack into the system and steal information or anything of that sort. Everything basically still works the same, everything is just kind of going on in one side the the VPN, which is identified as the Intranet. 

5.2 Extranet

With this diagram, it allows us to better understand how a business might use an extranet. My business that I am currently employed with is Love Shack Cabins, we rent out cabins. Another business that we might be accompanied with is Haynes Furniture. Within the extranet system we would have in LAN A, like drawn above, would be our business, Love Shack Cabins. LAN B would be our business that we are combined with, Haynes Furniture. If we need to get in contact with them we would be the client, we would  have to first be sent through the firewall to be approve that we are "legit" and are allowed to be contacting them through the VPN which is also the Internet. After we pass through the VPN we then come across another firewall to be approve to verify that we are not a scam of some sort and then we can connect with our business Haynes Furniture which would be the server to let them know of any know equipment that we might be purchasing from them. Everything that just mention is all what goes on inside of the extranet. 

Packet Switching Technology 4.3

The first thing that happens is TCP, transmission control protocol or internet protocol, IP, breaks the information down into data packets that make it easier to transfer the information from computer to computer. This is what is called packet switching. In order for the transferring to take place, there must be a router. A router allows two or more networks to connect. After the data has been packed it is then transferred to its destination. In order for all this to start there has to be a client, which sends a request to the server. The server is what does all of the work. When the data is being sent it has an IP address. The IP address is what allows the routers and networks to identify the data. All of this together is how we get the packet switching technology. If this didn't happen, any information that we needed sent like emails, would not be able to send and receive. 

5.1 Competitors website

The website that we chose to be our competitor was www.perfect-cabin-vacations.com/Florida-cabin-rentals/. With rule number 1 something that the website offers that is unique at the bottom of their page they have other websites and "deals" that might be helpful if maybe their prices are too high. My rating for rule number 1 is a 2. The reason for this being is that they only have 2 websites with other ratings and no special rates for their own product. The percentage on how often it is used is not very high at all, maybe the reasoning for that is because they don't have very many offers.

Rule number 2: I give them a 5 for something pleasing. They have beautiful pictures up that are very appealing. The pictures make you want to stay there showing the good locations.

Rule Number 3: I give them a 4 for the website being easy and fast to use. When you first pull the website up, it has different pictures of their cabins at different locations meaning cities in Florida, this allows you to pick which area you are interested in. It has many links to different places which is a plus.

Rule Number 4: Rule number 4 gets a rating of 5 because the pictures that they gives us to see are very nice and motivate the visitors to want to stay there.

Rule Number 5: They get a rating of 4 for rule number 5. They have pretty coloring and beautiful pictures but don't really have much advertisement. When using Alexa.com you find out that there is only 8 other websites that link into this website.

Rule Number 6: Rule number 6 gets a good rating of 5 because you learn a lot from this website. It allows you to read helpful information like the exact description of the cabins and locations. This allows you to choose which cabin you are interested in staying at.
