About Data GovernanceData Glossary - P
Parent-Child Relationship
A hierarchical realationship between data entities, where one of them (the child) can only exist if the other (the parent exists). For example, a city is the "child" to a "parent" state or country.
Pareto Principle
Also known as the 80/20 rule. This concept is used to prioritize activities, The Pareto Principle says that 80% of the value of any activity can be created with 20% of the effort.
Parse
see data parsing
Partitioned Database
A means of distributing a database by dividing it into segments that may be distributed to different functional units or geographical locations.
Performance Testing
Testing conducted to evaluate the compliance of a system or component with specified performance requirements.
Persistent Data
Data that outlasts the execution of a particular program or routine. It provides the records of the enterprise and is available for reuse.
Pervasive Computing
A ubiquitous, wireless, always-on, networked world.
Physical Data Model
A Data Model that is optimized for a specific DBMS. While Conceptual Data Models are completely devoid of database-level information, a Logical Data Model stores generic characteristics (such as indexes and foreign keys) without adding anything specific to a single DBMS. Physical Data Models translate information from a Logical Data Model to designs that are specific to a certain DBMS.
PKI
see Public Key Infrastructure
Plan-Do-Check-Act
Also called the Deming Cycle. A four stage cycle for Process management, devised by Edward Deming. PLAN: Design or revise Processes that support the IT Services. DO: Implement the Plan and manage the Processes. CHECK: Measure the Processes and IT Services, compare with objectives and produce reports ACT: Plan and implement changes to improve the Processes.
Planned Downtime
Scheduled loss of computing-system usage due to maintenance (such as database file modifications or application work), operational tasks (such as database backups), and periodic events (such as hardware/software/operating-system upgrades or disaster recovery testing).
Platform
Any base of technologies on which other technologies or processes are built and operated. Platforms provide interoperability, simplify implementation, streamline deployment and promote maintenance of solutions.
PM
an acronym for Project Management or Project Manager
Policy
Formally documented expectations and intentions.
Portfolio Management
The process of managing a collection of services and/or applications to maximize their value. It includesentifying the need for new services/applications and retiring ones that are no longer of value or do not conform with strategic plans or architectures.
Portfolio of Services
A published description of all IT services. see Service Catalogue.
Post-Compliance Paradigm Shift
Change in expectations that says that it's no longer acceptable to simply "do" work. Instead, for work that exists in an environment with compliance requirements, the work is not complete until you 1. Do it, 2. Control it, 3. Document it, and 4. Prove compliance.
Precision
A characteristic of data. It means that the data values should be just large enough to support the application or process.
Predictive Analytics
Methods of directed and undirected knowledge discovery, relying on statistical algorithms, neural networks and optimization research to prescribe (recommend) and predict (future) actions based on discovering, verifying and applying patterns in data to predict the behavior of customers, products, services, market dynamics and other critical business transactions. (DMReview definition)
Primary key
A data element (or elements) whose values uniquelyentify a row or record in the table. The primary key(s) will have a unique value for each record or row in the table. A primary key must be unique, stable, minimal, and not null.
PRINCE2
The standard UK government methodology for Project Management.
Privacy
In a data context, this is the expectation that personal information will not be improperly disclosed.
Private Data
Data that contains personal information and is subject to Privacy regulations and rules.
Procedure
A document containing steps that specify how to perform a process.
Process
A series of logically related activities or sub-processes performed for a given purpose.
Process Improvement
A discipline, program, or functional group focused on improving the performance and maturity of the organization's processes.
Process Maturity
A measure of how reliable, efficient and effective a process is.
Profile
see data profiling
Program
A collection of related people and efforts focused on a common objective, along with the projects and infrastructure that supports them, including objectives, methods, activities, plans, and success measures.
Project
An undertaking requiring concerted effort, which is focused on a specific goal. Projects have a definite beginning and end and typically operate according to a plan.
Project Management Office (PMO) Leader
An organization that manages sets of IT-related projects, providing guidance, best practices, structured processes, and trained Project Management staff.
Project Manager
A person who manages ta particular effort from start to finish. Responsible for the project's successful completion, the Project Manager directs the efforts of project staff,entifies and manages risks and issues, and serves as the project's interface with corporate management.
Propagation
see Data Propagation
Protocol
A set of conventions. In a technology communications and messaging context, they govern the communications between processes. Protocol specifies the format and content of messages to be exchanged.
Pseudonymization
The process of replacing a personallyentifiable field (like a patient's name) within a data record with an artificialentifier (a pseudonym). Unlike anonymization, this technique allows data to be traced back to its origin, and the resulting hash or lookup value can look very realistic without being real.
Public Key Infrastructure (PKI)
The combination of software, encryption technologies and services designed to protect the security of communications and business transactions on the Internet.
Publish And Subscribe
A communication pattern in which information sources "publish" (i.e., send) information to a somewhat intelligent middleware infrastructure, and information consumers "subscribe" by specifying what kind of information they want to receive from the infrastructure. The middleware must be able to physically transport messages from one or more publishers to one or more subscribers. It also must be smart enough to find the proper destinations by matching each message to subscription criteria. This model naturally supports one-to-many or many-to-many communication - in contrast to either message passing or message queuing, both of which mostly (but not entirely) aim at one-to-one communication.
