IUIE/IUDSS Glossary of Terms
Ad-Hoc Data Extract - User can select
rows and columns directly from the database through a point and click
interface. The IUIE generates the query
behind the scenes and return the data to the user. In the IUIE environment, data is extracted from datagroups and
can be returned in a web browser window or loaded into a spreadsheet, word
document, etc. (see Datagroup)
Ad-hoc Report - A report generated dynamically at the Information Consumer's request.
Base Table - Tables in the Data Warehouse that exactly match the structure and content of the operational data and which are generally available only to Data Managers (not DSS customers). Data is extracted from these base tables and modeled for easy reporting/analysis into datagroups.
Cross-subject Area Data - The intersection of data across functional areas. Similar to Student-Financial data.
Data Mart - A database, or collection of databases, designed to help managers make strategic decisions about their business. Whereas a data warehouse combines databases across an entire enterprise, data marts are usually smaller and focus on a particular subject or department.
Data Warehouse -
A data collection -- prepackaged or
summarized according to specific business rules and designed to support
management decision making. Data warehouses contain a wide variety of data that
present a coherent picture of business information.
Database Security - Selective access restrictions enforced through database-defined groups. Security constraints are implemented within the database as opposed to being in the different tools accessing the database.
Datagroup - a table or file in the data warehouse that has been modeled such that the development of reports and execution of queries is easier for the Information Consumer. A datagroup normally contains data that has been pulled from several different tables. It contains expanded descriptions instead of hard to understand codes. It may also contain summarized and/or precalculated data.
Denormalized Data - (See Normalized Data) Data is "denormalized" in DSS systems to reduce the number of tables that the programmer or Information Consumer needs to join together to obtain useful information.
DSS - Decision Support System. An information environment, including data stores and access tools, specifically designed for reporting and analysis.
Effective Dating - PeopleSoft-specific. The time period during which data in tables are valid. Effective dating adds flexibility to operational systems, but presents challenges in designing DSS datagroups.
Groups - Generally related to security; a category of users who have access to certain data, or have a category of privileges specific to a certain groups.
IUDSS - Indiana
University Decision Support System. See
DSS.
Master Catalog - A comprehensive listing of all Report Objects available in
the IUIE. Anyone using IUIE will see
the complete listings and metadata for each report, but will only have access
to the data if approved by an IP.
Metadata - In general, data about data, such as descriptions of database tables or fields. In the IUIE, there is metadata information about Report Objects.
Normalized Data - In relational database design, the process of organizing data to minimize duplication. Normalization usually involves dividing information into many database tables and defining relationships between the tables. The objective is to isolate data so that additions, deletions, and modifications of a field can be made in just one table and then propagated through the rest of the database via the defined relationships.
ODS - Operational Data Store. An exact copy, of both structure and data, from the operational system to the Data Warehouse. Not de-normalized. Primarily used as a source for building datagroups, or for special-purpose queries for Data Managers.
OLAP- Online Analytical Processing, a category of software tools that provides analysis of data stored in a database. OLAP tools enable users to analyze different dimensions of multidimensional data. For example, it provides time series and trend analysis views. The chief component of OLAP is the OLAP server, which sits between a client and a database management systems (DBMS). The OLAP server understands how data is organized in the database and has special functions analyzing the data.
OLAP Cube - Multidimensional set of data used for dynamic analysis
OLTP - On Line Transaction Processing-- A type of computer processing in which the computer responds immediately to user requests. Each request is considered to be a transaction. Registering students for classes or updating employee benefits are examples of transaction processing.
Operational System - The OLTP system
from which the DSS system derives its data.
Parm-driven query - a special type of pre-defined query which allows the
Information Consumer to supply parameters that will determine the content of
the formatted report. (see Pre-Defined Query)
Password - A secret series of characters that enables a user to access a file, computer, or program.
Personal Catalog
- A collection of folders, both default
and user-created , used to group Report Objects into meaningful
categories. By default, an IUIE user
will receive three folders: an inbox
folder, a new shortcut folder, and a completed reports folder. The user may also create folders into which
shortcuts to reports from the Master Catalog may be placed.
Point-in-time Data - A snapshot of data taken from a specific time. (i.e. census data, monthly operating report).
Pre-Defined Query
(PDQ) - a query or program that has been
previously written by an Information Provider or programmer. A pre-defined query will produce a formatted
report. Although the query is written
in advance, the Information Consumer can run these queries on demand. The Information Provider does not schedule
these queries to run on a regular basis.
Publication - Another
term for Report Object. A publication
may be either a report which would be accessed in its entirety, a report which
would be pared down by either user-entered parameters or SQL which would
generate a report on the fly, or a datagroup.
Publishing - the act of placing a Report Object in production to make it available to Information Consumers with proper access to the report (see Report Object)
Reference Tables - Look up tables that generally contain a code and an expansion of the code (such as a table that maps the code "BL" to the campus name "Bloomington").
Report Object - A listing in the Master Catalog or Personal Catalog of the IUIE, representing a datagroup, a PDQ, metadata, an Ad-hoc report.
Reports Viewing
Software - Software program utilized to view static or dynamic reports.
Roles - A category related to access or functionality. Examples: Information Provider, Information Consumer
SQR - A programming language for database processing and reporting.
Static Document - Generally refers to a report that does not change. Accessing the report will always return exactly the same information--no change to data.
Summarized Data - Analysis of the data has already occurred and a summary of the analysis is presented.
Userid - A unique identification of a person as it relates to accessing data or a system.
