2. SYSTEM ARCHITECTURE
2.1 SYSTEM DESIGN OVERVIEW
The caNanoLab system is created as a Java 2 Business Edition (J2EE) n-tier system that cultivates a loosely coupled and securely natural design where items in each rate are focused on certain building duties yet, easily incorporated with the other rates. The style of a caNanoLab grid data solution is described independently in area 4, not as a part of the caNanoLab system. The complying with style diagram reveals the general system design of the caNanoLab system. An overview of each tier is supplied in the sections immediately following the diagram.
Number 2-1: System Architecture
2.1.1 Customer Tier
2.1.2 Discussion Rate
The caNanoLab discussion rate is carried out using the Model-View-Controller pattern as well as via the Struts Servlet/JSP Structure and the Shingles Structure. The Struts ActionServlet intercepts every demand from the customer rate and inhabits a Struts ActionForm with HTTP demand criteria defined from customer inputs. These request specifications are verified with the Struts Validator Structure. As soon as validated, the ActionServlet starts a proper Struts Activity to process the demand and also pass the feedback back to a JSP web page for making. Shows off tag library, show tag library and JavaServer Pages Criterion Tag Library (JSTL) are made use of to assist dynamically render HTML web pages presented in the customer internet browsers.
Ceramic tiles Framework is used to separate format from web content such that the very same format elements are reused in various JSP web pages with different components, as well as programmers just need to keep one set of HTML design codes.
2.1.3 Business Tier
Business tier is accountable for applying business logic in the application and also bridges the gap in between the discussion tier and also the underlying information resources. The caNanoLab organisation rate includes company service items, data transfer items (DTO), utilities items, and the caNanoLab Plain Old Java Item (POJO) domain design that has been registered in the Cancer Facility Data Requirements Database (caDSR).
Each HTTP demand is converted into a company solution request as well as passed to the proper business service items for processing. Organisation service items communicate with Hibernate API (described in the Perseverance Tier) and also energies objects to obtain and also save domain name model objects. Additionally, business service things, along with utilities objects, apply service reasonings associated with fetching and also storing documents. Domain name objects are transformed into DTOs before they are passed back to the presentation rate.
2.1.4 Persistence Tier
The caNanoLab perseverance rate is applied utilizing the Hibernate object-relational mapping (ORM) framework. Domain things are mapped to database tables with the Hibernate ORMs. Hibernate API is responsible for generating SQL questions as well as handling database deals, and is used within the business service objects to communicate with the underlying databases.
Before an individual can send a demand to keep information into the data source, or prior to inquired data is presented back to the discussion rate, the application checks whether the user have the appropriate accessibility benefits to the data. Individual verification as well as authorization in the caNanoLab system is implemented via the API offered by the Common Security Module (CSM) readily available as a part of the Cancer Common Ontologic Representation Environment (caCORE) framework. The CSM API is likewise implemented using the Hibernate framework, and the CSM data source objects live in the same data source as the caNanoLab database things.
2.1.5 Enterprise Information System (EIS) Rate
The EIS tier is the backend tier that is responsible for providing and also keeping data. The caNanoLab EIS rate contains a caNanoLab data source and also a data system. The caNanoLab data source has data source items for keeping the caNanoLab application information, and has data source items for storing CSM authentication as well as consent information. The data system shops assay result documents, characterization documents, reports and protocols submitted in the application.
2.2 SYSTEM RELEASE
The caNanoLab system is created to be released in any type of Servlet container that complies with Java Servlet spec 2.4 as well as JSP requirements of 2.0. For both NCICBIIT and NCL implementations, JBoss Java 2 Business Version (J2EE) application web server integrated with Apache internet server is made use of to host the discussion rate, business rate and also the persistence rate of the system. At the NCICBIIT, the caNanoLab system is released in a four-tier hardware setting consisting of development, QA, staging and production. At the NCL, the system is released in a two-tier equipment setting including staging and manufacturing.
