Build the Trips Log app For this project, you will build a data-driven web app that uses view models to pass data from controllers to views, the ViewBag object to pass data from views to the layout, and TempData to persist data between requests.Specifications ? When the app starts, it should display trip data and an Add Trip link.? The layout for this web app should display a banner at the top of the page, and a subhead below it. However, the subhead should only display if there’s text in the ViewData property for it.? When the user clicks the Add Trip link, a three page data entry process should start.? On the first page, the user should enter data about the trip destination and dates. The Accommodations field on this page should be optional, and the rest should be required.? The second page should only display if the user entered a value for the Accommodations field on the first page. On this page, the user should enter data about the accommodations. The accommodation value the user entered should display in the subhead, and the fields should be optional.? On the third page, the user should enter data about things to do on their trip. The destination the user entered on the first page should display in the subhead, and the fields should be optional.? When the user clicks the Next button on the first or second page, the web app should save the data posted from the page in TempData. Use this data to get the user entries to display in the subheads as needed.? When the user clicks the Save button on the third page, the user will see the Home page displaying with a temporary message that the trip has been added with the details of the trip listed below.? When the user clicks the Cancel button on any of the Add pages, the data in TempData should be cleared and the Home page should display. You can use this statement to clear the data:TempData.Clear();

There are hundreds of database types and numerous database classes (relational, graph, NoSQL, flat file, etc.). Why do you believe technology firms keep on re-inventing the wheel and coming up with a new medium for data management (virtually every day). Please cite at least three examples and elaborate with business use cases.

Be your references in correct APA 7 format and cite each reference at least once, but as many times as you rely on it. Citations support each sentence relying on a reference, not an entire paragraph. Do not use direct quotes, rather rephrase the author’s words and continue to use in-text citations.Reply to each post needs to be 250 words minimum, with separate journal referencePost1:Technologies which has been used in order to maximize the radio frequency are basically divided into 3 types and each one has its sub types :long range : when then radio waves has to be send over a very long distance then we have cellular network which often have radio wave traveling to a large distance which are offend transferred from one network to the other depending on their receivers point (Acosta, 2019).sigfox :which use low data transmission rate and successfully avoid network interferences and ensure data transfer integrality. Satellite which through the help of uplink and downlink transfer the data which offers a high rate of data transmission (Acosta, 2019).medium range : we have wifi(transfer larger amount of data with good bandwidth ) and zig bee ( self-healing, secure, robust, and mesh-capable protocol)Protocols that wireless devices use to maximize their use of the available radio frequencies:-ZigBee (IEEE 802.15.4) – ZigBee offers 128 bit AES encryption. We see Zigbee in mesh topology based networks where all networks get connected through multiple pathways. The application of this protocol can be seen in home based IoT devices (Bhargava, 2019).Wifi (IEEE 802.11) – WiFi works on radio based frequencies. This protocol is used in networks where routers are used to connect with computers or two or more hardware components. It can utilize 2.4GhZ UHF and 5GhZ SHf ISM bands. There are three protocols 802.11b, 802.11g, and 802.11n which are used by 2.4Ghz (Bhargava, 2019).Bluetooth and BLE (IEEE 802.15.1) – For shorter distance data transfer we use bluetooth or BLE ( Bluetooth Low Energy) Protocol.For small devices like mobile phones, Laptops and Tablets, this technology is successful.Bluetooth uses UHF RF for data transfer (Kong, 2019).WiMax ( IEEE 802.16) – Worldwide Interoperability for Microwave Access (WiMax) is used by several mobile careers to transfer data at the speed of 30-40Mbps. This technology is successful for both indoor and outdoor use (Kong, 2019).There are various secure methods used to secure wireless devices and networks which are WEP, WPA and WPA2. WEP is considered as the most unsafe technology to use as a secutity as it uses unencrypted mechanism. WPA is secured and WPA2 is considered as the most secured encryption method as it provides security at more levels (Kong, 2019).Post2:Wireless technology has evolved to a whole new level. Over the last couple of years, technology has advanced in different aspects such as capabilities and design. More specifically, wireless technology has advanced with the development of Radio Frequency (RF) communication gadgets (Ray, 2015). These communication gadgets are able to transmit signals both in digital and in an analog format. The emergence of these technologies has improved the efficiency as well as the speed with which users communicate using wireless devices.There are various wireless technologies that are currently available in the digital world. One of the major examples of wireless technologies is the Wi-Fi (IEEE 802.11) technology. This technology s based on a radio frequency that uses routers to connect one or more computer hardware (Ray, 2015). This technology has been designed to operate on three major protocols with a different set of frequencies. The other common example of wireless technologies is the ZigBee (802.15.4) technology. ZigBee technology has security features in the form of 128-bit AES encryption. Additionally, this technology uses a mesh topology to allow connection through multiple pathways. This technology has wider application areas, including home-based IoT devices. The other common technology is the WiMAX (IEEE 802.16). This technology is designed to allow data transfer between devices at a speed that ranges from 30-40 MBps. This technology is sometimes used by mobile service carriers to deliver wireless data to their customers.There are various security protocols that can be applied to secure 802.11. Examples of such security strategies are the WEP, WPA, and WPA2. All these securities come from the same protocols but have been improved over time to offer better security features (Arefin et al.,

Risk1. Choose a project with a relatively simple description (building a LAN, designing a web page, inventing a new communication device, etc.). Describe your project scope in a few sentences and then identify at least five significant varied risks associated with the project. Be sure that at least one of them is a positive risk.Would each of these risks be considered major, moderate, or minor? What degree of likelihood and impact leads you to that assessment?Would each risk be best addressed by risk avoidance, risk transfer, risk mitigation/reduction, risk sharing, or risk acceptance?
