IT System Architecture
Service architecture is the physical design of a specific service that incorporates all the resources employed by the particular service. The physical design of a service includes the resources that make up the specific service. These components include the software components, databases, identity stores, legacy systems, shared directories and XML schemas. It is imperative to include the service agents utilised by the service since any alteration in these service agents can affect the message processing ability of the service. An example of a service is ATM withdrawal transaction (Hennessy & Patterson, 2011). The components of this service include the databases used to store customer information, the software components such as the operator panel used to access the database, the shared directories with other ATM services (Network), and XML schemas.
IT Management System Architecture
The architecture for this system is composed of several services, users and applications including; Students, School Administration, Teachers, Parents and Community. The services performed by this system includes academic services, administrative services, learning services, financial management services and IT management services. Additionally, the components of the system entail school cloud, Local server, administration and KPO Unit.
Enterprise Business Management System
The model that is best suited to support enterprise business management system is the decentralised model. Most IT management systems embrace the decentralised IT management model for authoring given its benefits as compared to the centralised model. Some of the major reasons behind this choice revolve around cost and increased involvement. Decentralised model presents an effective way to reduce costs while enhancing involvement (Hennessy & Patterson, 2011). While both models present benefits to enterprise business management systems, the advantages associated with decentralised model far outweighs those of centralised model.
Matrix in Data Modeling
Matrix is used in data modelling to simplify and to address complexities in computational and mathematical multivariate data (Hennessy & Patterson, 2011). The process of modelling multivariate data of actual life problems from physics, engineering and mathematics is a very significant and complex issue. The use of the matrix in data modelling helps in expressing multivariate problems regarding less-variate problems.
