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.

Members

In terms of RBAC, a set of users and user groups assigned to a particular role.

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.

Permission

Permissions control access to visuals, datasets, data connections, and system level functions. Arcadia Enterprise has three categories of permissions: System, Connection, and Dataset.

Plain authentication

The authentication mechanism is de-coupled from application protocols.

Privilege

A privelege consists of a set of permissions of a particular type and the associated components that define access. For example: permission View Visuals on component specifier Connection default / All datasets.

Role

In RBAC, a collection of privileges and associated members who are granted these privileges.

Role-Based Access Control (RBAC)

A mechanism for fine-grain control over data and feature access within Arcadia Enterprise interface.

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

Socket type

SSL with certificate

Socket type

Static Asset

Static assets are files that can be uploaded into Arcadia Instant 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.

Tooltip

A tooltip is a text box that appears when you hover the mouse pointer over a UI element. It displays descriptive information, such as simple values, aggregates, regions, trend formulas, and so on. Arcadia Instant enables you to customize the tooltip by placing items on the Tooltip shelf, in Visual Edit mode.

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.
