What is knowledge viability?
Knowledge viability refers to applications (most technology based) that offer easily accessible, accurate, and timely information obtained from a variety of resources and methods and presented in a manner so as to provide the necessary elements to generate new knowledge.
What does RDBMS stand for?
Relational Database Management System
What is a Relational Database Management System?
A relational database management system (RDBMS) is a collection of programs and capabilities that enable IT teams and others to create, update, administer and otherwise interact with a relational database.
What is the purpose of RDBMS?
RDBMSes store data in the form of tables, with most commercial relational database management systems using Structured Query Language (SQL) to access the database. However, since SQL was invented after the initial development of the relational model, it is not necessary for RDBMS use.
The RDBMS is the most popular database system among organizations across the world. It provides a dependable method of storing and retrieving large amounts of data while offering a combination of system performance and ease of implementation.
What are the benefits of RFIDs over Barcodes?
Can identify individual objects without direct line of sight.
Can scan items from inches to feet away, depending on type of tag and reader.
Data can be updated in real time.
Require a power source.
Read time is less than 100 milliseconds per tag.
Contain a sensor attached to an antenna, often contained in a plastic cover and more costly than barcodes.
What are the differences between a RDBMS and DBMS?
An RDBMS is a type of database management system (DBMS) that stores data in a row-based table structure which connects related data elements. An RDBMS includes functions that maintain the security, accuracy, integrity and consistency of the data. This is different than the file storage used in a DBMS.
Other differences between database management systems and relational database management systems include:
Number of allowed users. While a DBMS can only accept one user at a time, an RDBMS can operate with multiple users.
Hardware and software requirements. A DBMS needs less software and hardware than an RDBMS.
Amount of data. RDBMSes can handle any amount of data, from small to large, while a DBMS can only manage small amounts.
Database structure. In a DBMS, data is kept in a hierarchical form, whereas an RDBMS utilizes a table where the headers are used as column names and the rows contain the corresponding values.
ACID implementation. DBMSes do not use the atomicity, consistency, isolation and durability (ACID) model for storing data. On the other hand, RDBMSes base the structure of their data on the ACID model to ensure consistency.
Distributed databases. While an RDBMS offers complete support for distributed databases, a DBMS will not provide support.
Types of programs managed. While an RDBMS helps manage the relationships between its incorporated tables of data, a DBMS focuses on maintaining databases that are present within the computer network and system hard disks.
Support of database normalization. An RDBMS can be normalized, but a DBMS cannot.
What is RFID
RFID (radio frequency identification) is a form of wireless communication that incorporates the use of electromagnetic or electrostatic coupling in the radio frequency portion of the electromagnetic spectrum to uniquely identify an object, animal or person.
What are disadvantages of Barcodes?
Direct line of sight required for scanning.
Require closer proximity for scanning.
Data is read-only and can’t be changed.
No power source needed.
Read time is half a second or more per tag.
Printed on the outside of an object and more subject to wear.
What three components are needed for RFID to work?
Every RFID system consists of three components: a scanning antenna, a transceiver and a transponder.
What are the main challenges of RFID?
Reader Collision and Tag Collision
Reader collision
Reader collision, when a signal from one RFID reader interferes with a second reader, can be prevented by using an anti-collision protocol to make RFID tags take turns transmitting to their appropriate reader.
Tag collision
Tag collision occurs when too many tags confuse an RFID reader by transmitting data at the same time. Choosing a reader that gathers tag info one at a time will prevent this issue.
CPT - Current Procedural Terminology
The Current Procedural Terminology (CPT) code set, maintained by the American Medical Association (AMA), accurately describes medical, surgical, and diagnostic services. It is designed to communicate uniform information about medical services and procedures among physicians, coders, patients, accreditation organizations, and payers for administrative, financial, and analytical purposes. In addition to descriptive terms and codes, it contains modifiers, notes, and guidelines to facilitate correct usage.
Used to code traditional medical treatments, provided by physicians or NPs
ICD-10: The International Statistical Classification of Diseases and Related Health Problems: Tenth Revision
The International Statistical Classification of Diseases and Related Health Problems: Tenth Revision (ICD-10) is the most recent revision of the ICD classification system for mortality and morbidity, which is used worldwide. Both underlying or primary cause of death and non-underlying causes (other causes) are coded. Used to code for diseases, which are classified numerically by etiology and anatomic system
ICD-10-CM/PCS - Clinical Modification
Replaced ICD-9-CM. Used for classification of diseases and procedures associated with hospitalization
RxNorm
RxNorm is a standardized nomenclature for clinical drugs and drug delivery devices produced by the National Library of Medicine (NLM). Because every drug information system follows somewhat different naming conventions, a standardized nomenclature is needed for the consistent exchange of information, not only between organizations but even within the same organization. RxNorm contains the names of prescription and many nonprescription formulations that exist in the United States, including the devices that administer the medications.
