Enterprise-Wide & Cloud-Based Systems Flashcards
___ ___ ___ Systems provide transaction processing, management support, and decision-making support in a single, integrated package.
Enterprise Resource Planning (ERP) Systems
By integrating all data and processes of an organization into a unified system, ___ attempt to manage and eliminate the organizational problem of consolidating information across departments, regions, or divisions.
ERPs
ERP systems are typically implemented using a ___/___ network configuration; although early implementations generally utilized proprietary LAN and WAN technologies, current implementations often use ___-___ connections.
client/server; Internet-based
An ___ ___ ___ ___ incorporates data warehouse and data mining capabilities within the ERP.
.Online analytical processing (OLAP) system
The ___ ___ ___ ___ is the modules comprising the core business functions: sales, production, purchasing, payroll, financial reporting, etc. These functions collect the operational data for the organization and provide the fundamental motivation for the purchase of an ERP.
Online transaction processing (OLTP) system
ERPs may use two-tiered or three-tiered architectures ; because of the concentration of programs and data on a single system, ___-____ architecture is preferred.
three-tiered
A ___ ___ ___ is a virtual data pool that is created by contracting with a third-party data storage provider.
Cloud-based systems
____ ___ ___ ___ uses the cloud to access virtual hardware, such as computers and storage. Examples include Amazon Web Services and Carbonite
Infrastructure as a Service (IaaS)
___ ___ ___ ___ Creates cloud-based software and programs using cloud-based services. Salesforce.com’s Force.com is an example.
Platform as a Service (PaaS)
Remote access to software. Office 365, a suite of office productivity programs, is an example of ___ ___ ___ ___.
Software as a Service (SaaS)
What are the 4 goals of ERPs?
- Global visibility – The integration of all data maintained by the organization into a single database; once the data is in a single database — which binds the whole organization together. Once it is integrated into a single database, the data are available to anyone with appropriate authorization.
- Cost reductions – Long-run systems maintenance costs are reduced by eliminating the costs associated with maintaining multiple systems.
- Employee empowerment – Global visibility of information improves lower-level communication and decision making by making all relevant data available to the employee; this empowers the employee and, in turn, makes the organization more agile and competitive in a volatile business environment.
- “Best practices” – ERP systems processes are based on analysis of the most successful businesses in their industry; by adopting the ERP system, the organization automatically benefits from the implementation of these “best practices.”
What are the 5 benefits of cloud-based systems?
- Universal access – System data is available at any site with Internet access.
- Cost reductions – Long-run systems maintenance costs are reduced by eliminating the costs associated with maintaining multiple systems.
- Scalability – Cloud based systems are highly scalable, meaning that they grow with an organizations. Specifically, organizations can buy only the capabilities and storage that they currently need but can contract for expansion as organizational needs evolve.
- Outsourcing and Economies of Scale – Cloud-based systems allow organizations to outsource data storage and management to organizations with the capabilities and competencies to manage these facilities. By outsourcing to organizations who specialize in cloud services, economies of scale may be obtained, wherein the cloud provider realizes cost benefits, some of which are passed on to the organization who purchases cloud services. An additional benefit is therefore, obviously, cost savings due to a reduced need for internal IT personnel.
- Enterprise-wide integration – Cloud-based systems can be integrated with enterprise-wide systems to allow the seamless integration of organizational across units and geography. Indeed, some argue that fully realizing the benefits of ERPs requires cloud-based systems.
