Application Architecture. OLIN's application architecture shall at all times be developed and maintained by XXXX and shall be OLIN's responsibility. OLIN's application architecture shall govern the technological direction and specifications developed by XXXX in consultation with ARCH.
Application Architecture. As we continued, we considered the architecture of the application that surrounds the IA model. Doing so allowed us to compare how each IA model interfaces with the users and the database. Each IA model has a unique interface when considering the interactions of the individual centers and the ALTCDSS. The application architecture that surrounds each model can require more emphasis in data services on the individual healthcare centers or on the lead center depending on model. Furthermore, when concerned about data integrity, we could pinpoint weaknesses and strengths in the data conversion processes through this comparison. An application would need to be created to interact with the ALTCDSS. There are four main application layers that would exist, regardless of IA model: ❖ Presentation Interface- this is the layer that customers most often interact with. In this case, it would be the front-end of the ALTCDSS.
Application Architecture. Contractor shall provide an application architecture for converting each family of products to a modern sustainable application.
Application Architecture. Decision Lens exposes our decision technology via a web service API and provides user interfaces for delivering the decision process within a rich user experience. The user interfaces consist of standard web technologies, such as HTML, Javascript, CSS, and Flash. The user interfaces communicate with the web service API over the Internet to provide functionality to the end user. The web service API, and other related services, are implemented as Java web applications. These applications are deployed in Tomcat Application Server and are exposed to the Internet through an Apache HTTP Server proxy. The proxy enforces authentication and authorization logic for all web services based on user roles and data ownership rules. All application data is stored in a MySQL database. Application data is only accessible to web service API code and Decision Lens administrators via a secure, private network. All Ordering Activity data is logically separated for data integrity and security. Hosting Infrastructure Decision Lens utilizes Amazon Web Services IaaS* to provide a stable, reliable, scalable, and secure cloud-based SaaS platform. The multi-tenant architecture of the platform allows for Ordering Activity organizations to get up and running with Decision Lens quickly and easily. Additionally, Decision Lens supports Ordering Activity-hosted, on-premises installations of the platform. Decision Lens may be hosted in a single server environment, or in a multi-tiered, clustered environment, on virtual machines or dedicated hardware. Ordering Activity-hosted installations may be deployed with a custom architecture suitable for Ordering Activity needs. Please see the Technical Services section for more information regarding Ordering Activity-hosted installations. *See Appendix A for technical documentation regarding Amazon Web Services.
Application Architecture. Let’s consider an example of Web 2.0 application depicted in Figure 3-7. This is a typical 3-tier application consisting of three sets of components – the set of Web Servers, the set of Application Servers, and a set of Database Servers. Web Servers need to communicate with the external clients and with the Application Servers but not with the Database Servers and not between themselves. Application Servers need to communicate with the Web Servers and with the Database Servers but not with the external clients and not between themselves. Database Servers need to communicate between themselves and with the Application Servers but not with the Web Servers and not with the external clients. Additional requirements must be specified regarding the quality of the allowed connections, in terms of bandwidth, latency, packet loss, etc. Security and other service requirements, e.g. monitoring, traffic shaping, caching, can be specified by stating which of the allowed connections should be served by which types of service appliances. In traditional DCs, deploying the application described in Figure 2-1 usually requires interaction with the network administrator who will create network design, pre-provision the required subnets and services and let the application owner know where to deploy the application components and how to configure them over the network. Some of this work can be automated but the application owner is still exposed to network related aspects such as subnets, ports, gateways, IP addresses, etc. In VDC use case, the users are given an isolated slice of the networking underlying infrastructure where they can create and configure diverse networking designs suitable to the applications at hand. In multi-tenant software cloud use case, however, the user is the application owner and prefers to be isolated from the networking design aspects, concentrating on the application architecture and functionality. For a very large subset of typical cloud applications, e.g. multi-tier web applications, MapReduce applications, application clusters, networked storage application, etc., the patterns can be pre-provisioned. Moreover, both the cloud management stack and the underlying infrastructural resources can be optimized to better suit the specific patterns when they are deployed. In this use case, the user is the application owner (who can be either the developer or the operator). The application owner is knowledgeable about the application architecture, its com...
Application Architecture. Presentation layer: This is the graphical user interface of our application that shows information and takes input from users. • Business logic: We process input from the presentation and data layers and update each layer as required. • Data layer: The data layer that resides in the Cloud suite outside the actual device. All data is maintained on the booking system. We send requests to read data and to update data. For business-critical data the booking system is the “master” which makes the Cloud suite data layer less sensitive. Any data corruption or loss of meeting data would be read back automatically from the booking system.
Application Architecture. The data exchange between the OHAA system and the activity trackers namely FitBit will be enabled using REST API also called RESTFul Web Services - Figure G. The RESTful API takes advantage of the HTTP protocols defined by the RFC 2616 protocol, using the GET to retrieve response data, PUT to update resource data and POST to create the resources 6. The REST calls are stateless and that makes them most favorable for a cloud solution. The stateless features improve scalability based on the load as well as complexity free redeployment because requests can be processed by any instance. Another favorable feature of the REST API for cloud solutions is the ease and simplicity of how the URL is decoded when the REST service binds to a service through the API. Figure G OHAA and Activity tracker(FitBit) The OHAA system will pull FitBit data using FitBit’s Web API. The FitBit Web API uses the OAuth 2.0 authentication protocol. Using the OAuth 2.0 framework, the OHAA application receives an access token once the FitBit user authorizes the access to their activity data. The Access Token is a unique identifier that is generated for each individual FitBit user. It is used for making HTTP request to the Fitbit API. The access token will be stored in the OHAA as part of the patient identification information. Using the FitBit Web API, data can be collected for specific categories as listed below14 ● Activity ● Sleep ● Heart Rate

Application Architecture provides a blueprint for the individual applications to be deployed, their interactions, and their relationships to the core business processes of the organization. (TOGAF 9.1) In this segment, we identified the data and integration component of the ALTCDSS, studied several types of information architecture models, and conducted analysis to weigh the pros and cons of each as they applied to the ALTCDSS. Then, we considered the application architecture as it relates to each model to determine who and/or what would interface with the system and their complexities within.
