Glossary
Arcadia Data, Inc.
Arcadia Data, Inc., sometimes abbreviated as simply Arcadia Data, is a big data business
intelligence and visual analytics company. We are based in San Mateo, New York, and
London.
Arcadia Data has the backing of top-tier venture capital firms in Silicon Valley, and
counts as its partners and clients many Fortune 500 companies that use Hadoop and process
hundreds of billions of records.
Arcadia Enterprise
Arcadia Data's converged business intelligence and visual analytics platform. It is
completely native to Hadoop and resides “on cluster”. Arcadia Enterprise enables analysts and
business users to find business insights on the raw data, instead of working with tiny
aggregates and small extracts of the data.
Arcadia Enterprise includes both ArcViz and ArcEngine products.
Arcadia Instant
Arcadia Data's data modeling and visualization platform has an abbreviated list of
features. To enable the full suite of features, including Arcadia Engine, use Arcadia Enterprise.
Arcadia Instant includes the ArcViz product.
ArcEngine
Arcadia Data's on-cluster analytics engine, the ArcEngine scales directly with Hadoop clusters
for performance and ease of management.
ArcEngine is a versioned product.
ArcViz
Arcadia Data's Web-based drag and drop interface, the ArcViz is designed to enable intuitive BI
and exploratory analytics.
ArcViz is a versioned product.
Comma-Separated Values (CSV)
File storage for tabular data (numbers and text) in plain text. Each line of the file is a data record, where fields separated by commas. Arcadia supports enhanced importing and conversion from CSV to
HDFS, enabling datatype selection and other features.
Connection Explorer
The interface for managing data connections and information about data accessible through these connections.
Dataset
The foundation for all visuals and dashboards. Datasets are logical representations of
data we use to build visuals, dashboards, and applications. Datasets may represent the
contents of a single data table, or a data matrix from several tables that may be in different
data stores on the same connection.
Hadoop Distributed File System (HDFS)
HDFS is a scalable, distributed, portable file-system for the Hadoop framework. A basic Hadoop cluster has a single namenode and a cluster of datanodes. HDFS stores large files, in the range of gigabytes to terabytes, across multiple machines.
Kerberos
Computer network mutual authentication protocol that facilitates the exchange of secure identity 'tickets' between nodes that communicate over a non-secure network. Kerberos protocol is primarily a client–server model: both the user and the server verify each other's identity. The messages are protected against eavesdropping and replay attacks by symmetric key cryptography. Kerberos uses UDP port 88
by default.
Lightweight Directory Access Protocol (LDAP)
Open, vendor-neutral, industry standard application protocol for accessing and maintaining distributed directory information services over an Internet Protocol (IP) network. Directory services enable the sharing of information about users, systems, networks, services, and applications throughout the network.
NaN
NaN (nan
) is an abbreviation for "not a number", a numeric data type for an undefined or unrepresentable value, especially in floating-point calculations. For example, 0/0
is undefined as a real number, and √-1
is imaginary; both are represented by nan
.
Normal socket type
Socket type
NoSasl authentication
The authentication mechanism is coupled to application protocols.
Plain authentication
The authentication mechanism is de-coupled from application protocols.
Shelf
In Visual Designer, the shelves contain the dataset fields used in constructing the
visual. The user pulls the columns from the catalog of fields, places them on the appropriate
shelves, and adjusts various settings directly on the shelf.
Simple Authentication and Security Layer (SASL)
A framework for authentication and data security in IP, where authentication mechanisms are decoupled from application protocols. Thus, authentication mechanisms may be used in any application protocol that uses SASL. Authentication mechanisms can also support proxy authorization, where one user assumes the identity of another, and provide a service layer of data security for data integrity and data confidentiality.
SSL with certificate
Socket type
Static Asset
Static assets are files that can be updoaded into Arcadia Enterprise and
used across the organization to standardize the appearance of custom reports. Static assets
include image files, such a company logo, and styling options defined by
*.css
and *.js
files.
Visual Artifact
A visual artifact of the ArcViz system is a unity that may be migrated and shared between
ArcViz environments and instances. Visual artifacts include visuals, dashboards, apps (and
their subgroups), datasets (including defined segments and events), custom styles, thumbnails
of visuals/dashboards, and static assets (uploaded images, emails, html code, and so
on).
Visual Designer
The interface for constructing visuals and dashboards.
