1. Database - ANSWER ✓ a structured collection of individual data elements.
2. Database management system (DBMS) - ANSWER ✓ a software program
that is used to manage, organize, and retrieve data and information from a
database
3. Database model - ANSWER ✓ model that is used to structure the data in a
database
ie- relational database model (microsoft office)
4. Hierarchical Databases - ANSWER ✓ contain many levels.
Conceptualized as a family tree wherein each child has one parent. The root
is the head of the family. The branches, or second level, are the children who
are descended from the root. The third level, the grandchildren, are
descended from the second-level parents. Communication among the
descendants occurs by passing information up or down to the common
parent or child until the desired level is reached.
older mainframe DBMS
works well for data sets with one-to-many relationships
, requires professional programmers for maintenance
5. Network databases - ANSWER ✓ designed to solve the redundancy problem
that occurs with the hierarchical model
Although this model is very similar to the hierarchical model, children are
permitted to have more than one parent. The records are linked together by
pointers that use a key piece of data (e.g., a patient medical record number).
requires professional programmers for maintenance
6. Relational database - ANSWER ✓ The basic structure in this model is a
table. The database consists of several tables. A unique field within the
tables is used to combine or join the tables. In contrast to users of
hierarchical and network databases, users of relational databases need to
know only the name of a table in order to locate data
7. Object oriented database management system - ANSWER ✓ in a relational
DBMS there is a separation between the data storage and the manipulation
methods. This separation of data and methods for manipulating those data
add to the complexity of the database. This is especially true with large
databases
8. Right clicking on a selected object yields a menu of options that can be
applied to the selected object. The same principles apply to data in an object-
oriented DBMS.
reduces the amount of programming needed
9. Anatomy of a database - ANSWER ✓ consists of fields, records, and tables
10.Tables are the basic building blocks of a relational database.
11.Fields - ANSWER ✓ a vertical column in a database. It contains data that
represent the same characteristic, or entity, for all of the records.
12.For example, a column labeled "First Name" would include the first name of
each individual.
, atomic level data
13.Records - ANSWER ✓ horizontal rows are called records. A record contains
the different pieces of data belonging to a given entity. In this table the entity
is a person, and the fields contain his or her name and mailing address. Thus
a record is made up of fields, with each field containing data pertaining to
the entity that the record represents.
14.Tables - ANSWER ✓ consists of all of the records.
15.Structuring the data in fields and records in a table makes it possible to
manipulate and/or select records or fields based on specific data elements in
the fields.
16.Atomic level data - ANSWER ✓ or the smallest recognizable entity
necessary to obtain meaning.
17.To keep data at the atomic level, three fields are used to collect a name—
first name, middle initial, and last name
18.The address is divided into the street address, city, state, and zip code.
Keeping data at this lowest level provides flexibility in data use.
19.Querying - ANSWER ✓ The process of selecting desired records is called
querying, and the feature that permits this is a query.
20.Form - ANSWER ✓ A view of the data in a table that, although derived
from the data in a table or tables, can be structured to present specified
fields, calculated data based on data in a table, or fields from many tables.
The form demonstrates the structure that will be used to format a report. It is
this ability that makes possible the data entry concept of "entry once, use
many times"
21.Report - ANSWER ✓ A view of the data in a printed table. The data can be
structured in any way that is useful to the viewer. Among possibilities, data
can come from multiple tables, be grouped by criteria, or be calculated.
Because reports are organized to be meaningful for the viewer, they can also
be defined as the display of information
, 22.Algorithm - ANSWER ✓ set of rules to follow that are inclusive of all cases.
23.Wildcard - ANSWER ✓ Symbols that are used to represent the characters in
the truncation process. In many systems the use of an asterisk (*) denotes
any number of and any kind of character, and a question mark (?) denotes
one character
24.relational databases - ANSWER ✓ consist of four main objects: table, query,
form, and report. The table, with the data organized into fields (vertical
columns) and records (horizontal lines), is the heart of any database. A table
is where one starts when physically constructing a database. Without it, none
of the other objects can be created.
25.flat database - ANSWER ✓ A database consisting of a single table
26.HIS implementation benefits to healthcare- ANSWER ✓
can improve cost control, increase the timeliness and accuracy of patient
care and administration information, increase service capacity, reduce
personnel costs and inventory levels, and improve the quality of patient care.
27.Nurse informaticist role in health information system- ANSWER ✓
Looks for information, verifies ownership of information and connects other
parties within the healthcare organization.
28.Lewin's Change Model- ANSWER ✓
unfreezing, changing, refreezing
(planning, action, results).
29.Shannon & Weaver's mathematical model- ANSWER ✓
30.Encoder (Transmitter) –Encoder is the sender who uses machine, which
converts message into signals or binary data. It might also directly refer to
the machine.
