N-Z
- Application Custodian
- The branch director who sponsors projects to develop information
systems, and provides ongoing support for those systems, to enable staff to
meet business needs. This includes responsibility for systems releases,
security matrix, processing needs, backup/recovery requirements, bridging
requirements to current systems on other computing environments, etc. An
Application Manager would carry out the day-to-day responsibilities that
the Application Custodian is accountable for. See
Guide S35, and
Ministry of Forests Policy 7.3.
- Application Development Environment (ADE)
- All tools and techniques used by an organization to deliver information
systems.Technology, standards, and related considerations that pertain to
application development, excluding the utilities, software services,
operating system, network, and hardware platform. Examples include a
repository; standard 3GLs or 4GLs; and system environments for development,
test, and production.
- Application Programming Interface (API)
- "The formally defined programming language interface between a program
provided by a vendor and its user."
- Asynchronous Transfer Mode (ATM)
- A wide area network communications protocol with a high bandwidth.
- Bandwidth
- The transmission capacity of data over a network.
- Build Table Exec (BTE)
- A Ministry of Forest-developed VM application which records database
definition information for the SQL/DS development environment. This is used
in conjunction with the on-line application dictionary to develop the
database definition language.
- Business Architecture
- The business architecture stems from the business master platform and
includes specific products and services that the enterprise will offer,
talent pools it will recruit and organize, policies it will develop to
govern corporate behaviour and value systems it will cultivate over time.
- Business Master Platform
- A business mater platform is a subset of reality that includes legal,
geographic, human, competitive and technological opportunities and
constraints that bear on how the enterprise must operate to succeed.
- Business Process Automation
- "BPA is the extension of end-user information access and services for
complex business functions, beyond traditional data manipulation and record
keeping activities, through the application of advanced technologies (e.g.,
object orientation, client/server, real-time systems, 'next-generation' CASE
tools, etc.)."
- CCSM
- Canada Council on Surveying and Mapping, the custodian of national
feature codes. The CCSM 1984 Draft Report on the classification of
topological features is used as a government-wide standard. The Ministry of
Forests uses this standard to create Feature Codes.
A Government Feature Codes Database
has been set up by the Ministry of Sustainable Resources where users can
query for feature codes maintained by the province.
- Client/Server
- "An application of co-operative processing in which the end-user
interaction with the computing environment is through a programmable
workstation that executes some portion of the application (beyond terminal
emulation)."
"An architecture of co-operative processing with predefined roles for two
types of components, clients and servers. The client is the driving or
initiating component, typically on a workstation, delegating predefined
types of tasks to a responding component satisfying the request, the server,
for which it usually awaits a response. The server acts on behalf of a
client for a predefined class of functions, e.g., database requests."
- Control ID
- see Feature ID
- Co-operative Processing
- "Two or more complementary programs interacting and executing
concurrently on two or more machines (often different tiers) as part of an
overall business function, whereby each component exploits the operating
characteristics of its respective platform."
- Computer Aided Software Engineering (CASE)
- A CASE tool is "a software program that provides partial or total
automation of at least one function within the software life cycle, e.g.,
entity relationship diagram editor, a data dictionary consistency checker or
a code generator."
Upper CASE tools are "application development technologies which address
problem definition, requirements specification, analysis and design. A tool
for modelling applications requirements, systems analysis and data
structure."
- Lower CASE tools are "application development tools which address
program and screen design and program development. Lower-CASE tools include
screen painters, program generators and 4GLs." Integrated CASE (I-CASE) is
"any cohesive set of unified CASE tool kits or CASE workbenches that support
a large proportion of the systems development life cycle. The degree of
integration among the tools can vary widely"
- Integrated CASE (I-CASE) is "any cohesive set of unified CASE tool kits
or CASE workbenches that support a large proportion of the systems
development life cycle. The degree of integration among the tools can vary
widely.
- Conceptual Model
- An initial system design (i.e. initial prototype) from information
gathered during User Requirements and is used as the straw man for a Detail
Design JAD.
- Corporate Data
- Data is
Corporate if it is
- vital to the ministry (i.e. critical to the ministry's business)
- of a permanent nature (i.e. kept for a significant period of time)
- within the ministry's mandate (i.e. part of the ministry's legal
business)
- Therefore, Non-corporate data is data that does not meet one or both of
the above points. Non-corporate data may have a significant impact on an
individual (e.g. if they lose/delete their personal calendar), but the
organization's business on the whole won't be affected.
- Data Administrator
- The position in the Ministry responsible for leadership in managing
information as a resource, analysis of data custodianship needs, conceptual
design of data structures necessary to manage data custodianship, and
enforcement of proper logical data design in the systems development
process.
- Data Custodian
- The Data
Custodian is responsible for deciding what data to collect (how much,
how detailed, how accurate), how the data will be used and where to
store/retrieve it. The Data Custodian is always a branch director and is the
person ultimately accountable for ensuring that the data is properly defined
and that it represents the business requirements. The branch director may
delegate the day-to-day responsibilities of this job to another person (the
Data Standards Manager).
- Data Custodianship
- Responsbility for data inventory (gathering and managing facts about
business data required by the Ministry); data management (establishing
policies, procedures, standards, and guidelines to attempt to improve the
accuracy, timeliness, consistency, standardization, and worth of
information); data sharing (promoting data sharing by obtaining concurrence
of opinion of information needs throughout the Ministry, and encouraging the
joint funding or sponsorship of databases across departmental, application,
and political boundaries); and data conflicts (attempting to resolve or
prevent conflicts in data ownership, use, interpretation, and meaning, and
functioning as negotiator and arbitrator to achieve such compromises). See
ISB's System Development Guides,
Guide S35,
Management Guide to Custodianship.
- Data Definition Language (DDL)
- A series of Structured Query Language (SQL) commands used to define
objects.
- Data Maturity Categories
- In any large organization, data is defined, collected, transformed,
used, summarized and reported for the purpose of making business decisions.
The value of such data is commensurate with the amount of resources that
went into its definition, collection, and use. Data that is collected in an
ad-hoc manner with no standard method is of far less value than data defined
for a business purpose that has been thought through and agreed on by all
affected business staff. Data collected using a common standard can be
thought of as being more "mature" and more useful to the organization. The
Data Maturity Categories are: Non-Corporate Data, Local Corporate Data,
Extended Corporate Data, and Full Corporate. Data. See also:
Corporate Data
- Data Resource Manager
- The staff responsible for collecting data at the field level, although
ultimate accountability rests with the senior manager of the office (e.g.
District Manager). The Data Resource Manager (DRM) is accountable for
collecting Corporate data to the standards set by the Data Custodian.
The DRM is a key role for the ministry: where Full Corporate data does not
exist, they will determine what data is important enough to begin moving
into the Extended Corporate category. See
Statements of
Responsibility for Data Resource Managers.
- Data Standards Manager
- The Data Custodian (usually the director of a branch) may delegate the
day-to-day responsibilities of custodianship to another staff member known
as the Data Standards Manager. This staff person does not necessarily have a
management classification -- it is the person who does the day-to-day
management of the data standards, for the Data Custodian. See
MoF list of
DSMs.
- Data Warehouse
- "A mechanism for supporting strategic decision making, [based on] the
belief that the nature of data to support that function is inherently
different from transaction-oriented operational data." The "notion [ ]
emphasises decision-support needs directed at 'atomic' data derived from
operational databases."
"Building a data warehouse [ ] means that the sources of that data have to
be identified in operational systems, and [ ] it means defining a new data
model to support the decision-making requirements."
- Also see "informational data" and "operational data".
- Database
- A repository of database tables that has built-in management for
inserting, updating, and deleting elements of any one table, and for
maintaining table integrity.
- Database Management System (DBMS)
- Database Management System. DBMS is a tool that provides comprehensive
support for storage and management of corporate data. It provides an
environment to support distributed database, referential integrity, two
phase commit, sophisticated security, and a high level of transaction
processing support.
- Database Table
- A repository of data of which users are aware and from which data can be
read repeatedly and non-destructively. A table contains all occurrences of
data whose structure is defined by an entity, i.e. the CLIENT table would
contain each client known to the Ministry, along with all other information
identified by the CLIENT entity (such as NAME, ADDRESS, PHONE, etc). This is
essentially the information contained within an entity type, but implemented
physically as a table in a computer system database.
- Distributed Computing Environment (DCE)
- DCE is a specification by the Open Software Foundation (OSF) of services
for interoperability of applications on heterogeneous platforms. It
comprises "two service sets: fundamental services including naming, timing,
threading, security and RPC [ ] and data-sharing services, including a
distributed file system and PC support."
- Distributed Data Centre (DDC)
- The term used to describe the sixty plus standard LANs throughout the
ministry of Forests, which are locally supported and managed, to indicate
that they are a distributed component of the ministry's technology
infrastructure.
- Distributed Database
- "A DBMS that enables end users or application programmers to view a
collection of physically separate databases as one logical single-system
image. The concept that is most fundamental to DDBMS [distributed DBMS] is
location transparency, namely that the user should not be conscious of the
actual location of data."
- Distributed Relational Database Architecture (DRDA)
- A data access protocol by IBM to enable LAN workstations to process data
from DB2 databases anywhere on the network.
- District Office System Specialist (DOSS)
- The title used by the Ministry of Forests for an information
technologist in a district office.
- Enhancement
- Larger cost work that adds functionality, or addresses missing
functionality to the application.
- Enterprise Information Architecture (EIA)
- "In terms of tangible deliverables, then, an EIA is at its core the APIs
that an enterprise's developers will use and the hardware and software
products that will support them, with attendant rationale, transition
planning, and resource projection."
"Key enabling components [are] application development environment, target
operating systems and target hardware platforms."
- Enterprise Server Platform
- "An ESP [is] an inherently distributable, multiply interoperable server
that is engineered for use within a larger IT architecture and that
transparently provides services to any authorised client. [ ] an ESP is
essentially a collection of services that can be distributed across several
computers to gain advantages in price/performance, in system availability
and in such platform services as dedicated file and print, fault-tolerant
servers and electronic mail gateways."
"An enterprise server platform (ESP) can be considered a single system,
despite its deployment across multiple nodes, hardware architectures and
operating systems. Programmers should view the ESP as a common set of APIs.
To client systems it should be a common set of interconnection, data access
and program interaction protocols."
- Entity Type
- A definition of structure for a collection of uniquely identifiable
facts about people, places, things, or concepts that are of fundamental
importance to the Ministry's business, and to which a specific definition
and common attributes apply.
- Example: A client's name, address, and phone number is information
important to the Ministry is order to do business with that client, and the
information requirements are defined by the Entity Type CLIENT, identified
by CLIENT_NUMBER, containing attributes NAME, ADDRESS, PHONE, etc. (The
information would actually be stored in a database table, i.e. see example
in the definition of Database Table).
- Extended Data
- Extended data is corporate data that is used locally (e.g. in the
district(s)). It differs from Local corporate data in that some energy has
been put into defining Extended data from a ministry-wide context. See also:
Corporate
Data.
- Feature
- (also known as spatial feature) A business item of interest that, as
part of its vital information, is directly associated with a geographic
location: i.e. a geographic object or unit of geographic data. Every
distinct item of geographic data of interest to the Ministry of Forests is a
feature.
Features have a Feature Class Name and a Feature Code to specify what type
of feature it is (e.g. lake, opening, road, recreation trail, etc.).
Features also have a Feature ID to uniquely identify each instance of the
Feature (e.g. to identify Lake Okanagan from Christina Lake). There is also
some spatial and attribute data associated with each feature.
- For example, a Forest Cover Polygon would have a Feature Code, a Feature
ID, associated linework and an inside point, and some associated attribute
data such as Leading Tree Species Type.
- Feature Class
- A Feature class is defined to classify and describe a geographic
feature. A "feature" differs from a "feature class" in that the feature is
an instance of the feature class. For example, "Lake" is a feature class
while "Nitinat Lake", "Christina Lake" and "Lake Okanagan" are features.
Other examples of feature classes are: Opening, Forest Cover, Range Unit,
Recreation Trail, Resource Management Zone, Biogeoclimatic Zone, Forest
District, etc.
- Feature Code Number/Feature Code
- Geographic features are classified using a feature class name (e.g.
lake, road, trail, etc.) and are "encoded" using a Feature Code Number
and a Feature Code. Feature Code Number and Feature Code both serve
the same purpose - they are used to uniquely identify the "type" of feature
and are more useful than a name which is more likely to change.
Feature classes and feature codes are useful in that they can be used to
manage and reference groups of features in order to perform certain
operations. They enable us to associate other descriptive information with a
feature such as whether it's a point, line or polygon, a description for it,
what symbology is used (e.g. level, colour, line weight, etc.) and so on.
- The Feature Code Number is stored as a numeric value (e.g. 16025
might be the Feature Code Number for the "Resource Management Zone"
feature class). The Feature Code is an 10-character alphanumeric
value, starting with 2 letters, followed by 8 digits (e.g. AR24400000
might be the Feature Code for "Resource Management Zone").
- The Feature Code is used government-wide and is generated in compliance
with the Canada Council on Surveys and Mapping (CCSM) 1984 Draft Report on
the classification of topographic features. A
Government Feature Codes Database
has been set up by the Ministry of Environment where users can query for
feature codes maintained by the province.
- The Ministry of Forests currently uses the Microstation platform for
spatial data capture and the Microstation platform cannot use a feature code
which has an alphanumeric value. For this reason, the Ministry decided to
create the Feature Code Number - it has the same business use as Feature
Code but is stored as a numeric value. The Feature Code Number exists only
within the Ministry of Forests.
- Feature ID
- In order to uniquely identify features stored by the Ministry it is
important that each feature have a unique key. Historically, spatial and
attribute data have co-existed in separate worlds - attribute data is
typically stored in relational databases and spatial data is captured and
stored on CAD or GIS platforms. The only way of linking the two together was
by storing unique identifiers as labels in the spatial data, generating a
map and then manually associating the labels with unique identifiers stored
in the attribute database.
- One of the initial goals of the INCOSADA project was to provide a
physical link between the spatial and attribute databases. A unique key,
known as the Feature ID, was created, consisting of two fields, the
Control ID and Generated Number.
- The Control ID was created to meet the requirement that business
areas be able to generate feature ids, independent of location and program
area (e.g. a LIM operator in Dawson Creek should have complete control over
the feature ids generated at that site and the feature ids must still be
unique over the entire province). Each business area or location, therefore,
may have one or more Control IDs assigned to it and can then freely assign
Generated Numbers under each Control ID.
- The Generated Number is implemented as a sequential number or
counter and is used to identify one instance of a feature within a business
area. When used in addition with the Control ID, the key is unique within
the province.
- The Business Design Branch is the custodian of Feature ID. They will be
establishing processes to control the allocation of Control IDs and
Generated Numbers.
- Full Corporate Data
- Full
Corporate data is the most mature data, where a Data Custodian has
defined ministry standards for its definition, collection, entry, and use.
Full Corporate data can be further broken into Shared (used by several
business areas) and Program-Specific (all collection and use is within the
same line program -- e.g. lightning location data). Most Full Corporate data
is Shared.
- Function
- A normal or characteristic action of the Ministry which is a continuous
major activity and must be accomplished to satisfy the mission of the
Ministry. A major act, operation, role, or duty for which authority,
responsibility, and jurisdiction has been determined. Continuous in time.
- GDBC
- Geographic Data B.C., the branch of the Ministry of Environment, Lands
and Parks responsible for provincial mapping standards and the TRIM project.
- Generated Number
- see Feature ID
- Graphical User Interface (GUI)
- A term given to an interface such as Windows that provides more than a
text based interface such as MS-DOS. A GUI usually includes a mouse and has
a rich set of tools or widgets such as icons, radio buttons, windows,
maximize and minimize buttons.
- Historical Data
- Corporate data that has been copied, summarised, or transformed, and is
stored permanently; usually for the purpose of comparing it to other data in
the future to look for business trends. Essentially, historical data has had
the dimension of time added.
See also Archived Data.
- IGDS
- (Interactive Graphics Design Software created by Intergraph). This
binary file format is a standard in the turnkey CAD market and has become a
de facto standard in Canada's mapping industry. The Microstation CAD
platform uses IGDS file format and is the standard CAD tool used by the
Ministry of Forests.
- INCOSADA
- The Integrated Corporate Spatial and Attribute Database is a project
intended to standardize and streamline the handling of spatial data within
the Ministry of Forests.
- Information Access (IAC)
- The Information Access Project provides the means to get copies of
mainframe data to a distributed data center. It will utilize the Data
Delivery System for transporting the data. This facility will enable
custodians of applications to provide reporting capabilities to distributed
data centers.
- Information Engineering (IE)
- "The application of an interlocking set of formal techniques for the
planning, analysis, design and construction of information systems, applied
on an enterprise-wide basis or across a major sector of an enterprise."
- Information Engineering Facility (IEF)
- An integrated CASE tool set from Texas Instruments which is used by the
Ministry of Forests for data modelling.
- Joint Application Design (JAD)
- A process where the clients and developers interact to design
applications.
- Legacy Technology
- Information technology which does not have the characteristics of
contemporary technology, such as openness, client-server design, or
relational data model.
- Level
- Levels allow data to be input into a Geographic Information System as
separate themes and overlaid based on analysis requirements. Levels are
completely user definable and are also known as: layers, theme, and
coverage.
- Local Area Network (LAN)
- Two or more computing units connected for local resource sharing. A
network in which communications are limited to a moderate-sized geographic
area, such as a single office building, warehouse, or campus, and that do
not extend across public rights-of-way.
- Local Corporate Data
- Local
Corporate data is data that has context in the local program only. For
example, this may be data collected to often different standards but still
shared among multiple districts (with the associated formatting and
translation problems!). Staff using this data generally know its limitations
and are careful. What sets Local data apart from Non-corporate data is the
fact that the data is vital to the ministry's business, and is permanent.
- Maintenance
- Addresses deficient and/or emerging lower cost functional requirements.
Also addresses issues affecting routine operations, such as Hardware,
Software and Data issues.
- Metadata
- Data attributes that record information about data requirements of an
application (data about data). The definition used by the ministry limits
metadata to information not recorded by the application (update userid would
not be considered metadata, but rather data recorded by the application. The
userid of the person who added update userid to the database would be
considered metadata).
- Method
- A method is a function performed on a window or object through program
coding.
- Methodology
- A description of the techniques and steps used to identify, organise and
transform business requirements into application systems
