What is the most important task that an administrator can oversee and engage in?
Data mining
These are knowledge workers who harness information and knowledge at their fingertips to facilitate the practice of their clinicians, improve patient care and advance disciplinary science
Astute informatics
CIS
Clinical information system
SDLC
System development life cycle
Rad
Rapid application development
OOSD
Object-oriented system development
DSDM
Dynamic system development method
This is a way to deliver efficient and effective information systems that fit with the strategic business plan of an organization
SDLC- systems development life cycle
This is one of the oldest methods and depicts a waterfall effect, that is the output from each previous phase flows into or becomes the initial input for the next phase
Waterfall model
Many projects are broken down into 6 phases:
Feasibility Analysis Design Implement Test Maintain
This is used to determine whether the project should be initiated and supported
Feasibility
TELOS strategy
Technological and systems, economic, legal, operational, and schedule feasibility
What does the TELOS strategy do?
Addresses the issues of technological capabilities including the expertise or infrastructure to complete the project
During this phase of a project the requirements of a system are tested out from a detailed study of the business needs of the organization.
Analysis
This phase of a project focuses on high and low level design and interface and data design.
Design
During this phase of a project the designs are brought to life through the programming code.
Implement
During this phase of a project it is broken down into 5 layers: individual programming modules, integration, volume, system as a whole, and beta testing
Test
During this phase of a project the system has been finalized from a testing phase and it must be? This could be supported through software changes.
Maintained
This approach is linear and progresses sequentially
Waterfall approach
When should the waterfall approach be used?
For simple projects when the requirements are well known and stable from the outset (most projects do not remain static)
What is RAD (rapid application development) known as?
Rapid prototyping
This provides a fast way to add functionality through prototyping and user testing and why is it used?
Rapid prototyping, because it is easier for users to examine prototypes than actual documentation
The ____ approach uses informal communication, repurposes components, and typically follows a fast paced schedule.
RAD approach (rapid application development)
This model blends the SDLC logic with object oriented modeling and programming power. It makes an effort to represent real world objects by modeling the real world entities or things.
OOSD- object oriented systems development
