Advanced analytical data

Advanced analytical data is a particular type of enterprise data. It is created by applying methods of data science that go beyond purely descriptive analytics (i.e., towards predictive/prescriptive analytics). It is used to identify patterns or correlations in complex (structured and unstructured) data sets (including text and geospatial data, for instance).

Big Data

Big data are data that are so large and diverse that they require cost-effective, innovative forms of data collection, storage, management, analysis and visualization. Big Data are typically characterized by 3 V's: Velocity is the speed at which the data is created and the speed at which the data shoud be analyzed and used. Volume refers to the size of the data which is typically in the range of terabytes and exabytes, whereas variety refers the changing data types in scope ranging from more traditional structured source (spreadsheets, SQL database tables) to semi-structured data (XML, JSON, Semantic Web data) as well as unstructured data (images, texts, files). In recent years, three more V's have been added to the the traditional 3 V's framework to charactarize Big Data: Variability, Veracity and Value. Veracity refers to different levels in reliability and truthfulness of big data sources, while variability describes the high frequency of changes within a data sources. Last but not least value describes the fact that while single data points may not be of high value, value from big data comes from analyzing huge amounts and trends within and between datasets.

Business Analytics

Business analytics: Business analytics is defined as the exploration and investigation of past business data to gain valuable insights and drive business planning. These activities depend on a sufficient volume of data as well as on a sufficient level of data quality. This requires data managers to integrate and reconcile data across various sources (i.e. from various business units, divisions, departments, branches, and information systems), with the goal of compiling a complete picture of the company’s past and current state for deriving future scenarios.

Business Capabilities

Business capabilities define a set of data-based skills, routines, and resources a company needs to have in order to achieve its business goals through data monetization. The Business Capability design area specifies what data-related business capabilities are required, which of these are already in place to some extent and need to be enhanced, and which ones need to be established from scratch.

Data catalog

A Data Catalog is an integrated platform for data curation, matching data supply and demand. It offers users functions to register data; to retrieve and use data; and to assess and analyze data. A Data Catalog therefore should provide a data inventory (for data supply) and features for data discovery (for data demand) as key components. Additional features should support data governance, data assessment, and data analytics, alongside with appropriate features for catalog administration and data collaboration.

Data governance

A company-wide framework that determines which decisions must be made and who should make them. This includes the definition of roles, responsibilities, obligations and rights in handling the company’s resource data. In this, data governance pursues the goal of maximizing the value of the data in the company. While data governance determines how decisions should be made, data management makes the actual decisions and implements them.

Data integration

Data integration is the task of presenting a unified view of data owned by heterogeneous and distributed data sources". The need for data integration may stem from (1) technological heterogeneities (different database technologies) (2) schema heterogeneities (different data models and data representations) and (3) instance-level heterogeneities (conflicting values in different sources for the same data object). Data can be physically integrated or virtually, meaning that the data will remain in the source systems, however will be accessed using a uniform view.

Data lifecycle

In the CDQ Data Excellence Model, the data lifecycle comprises all processes regarding the creation, acquisition, storage, maintenance, use, archiving, and deletion of data. For a given data object, it defines and documents the data sources, data supply chains, data consumers, and data use contexts.

Data literacy

The continuous learning of core skills, knowledge, attitude and values required to interpret data in a critical manner, and derive meaningful and actionable business insights.




Data management

Data management aims at the efficient usage of data in companies. It makes decisions and executes measures that affect the company-wide handling of data (whereas data governance creates the framework for such through the definition of responsibilities and so forth). It comprises all tasks related to the data lifecycle on a strategic, governing, and technical level: the formulation of a data strategy, the definition of data management processes, standards, and measures, the assignment of roles and responsibilities, the description of the data lifecycle and architecture – covering data models and data modeling standards –, and the management of applications and systems.

Data owner

The data owner is a core data & analytics role in the CC CDQ Reference Model for Data & Analytics Governance. Two different role types of data owner are usually being distinguished in practice: data definition owner and data content owner.

The data definition owner is a decentralized data governance role which is assigned typically to senior business executives with global outreach (e.g. Global head of sales). (S)he is accountable for the data definition in specific areas of responsibility (e.g. a specific data domain like product or customer). Here, (s)he ensures that business requirements are fulfilled and data is compliantly accessed and used. Her/his tasks include collecting/defining data requirements and delegating the detailling of a data definition to a data steward.

The data content owner is a decentralized data governance role which is assigned to local business executives/ team leaders with operational responsibilities. (S/he) is accountable for data creation and maintenance (Data lifecycle) according to the data definition for a specific area of responsibility. (S)he coordinates the creation and maintenance of data by data editors.

Data product

A data product is a managed artifact which satisfies recurring information needs and creates value through transforming and packaging relevant data elements into consumable form.

Data quality

Data quality is a multi-dimensional, context-dependent concept that cannot be described and measured by a single characteristic, but rather by various data quality dimensions. The desired level of data quality is thereby oriented on the requirements in the business processes and functions, which use this data, such as Purchasing, Sales or Reporting. A low level of data quality will reduce the value of the data assets in the company, because its usability is minimal. Companies are therefore striving to achieve a quality of data required by the business strategy using data quality management.

Data quality dimensions

The most important dimensions whose data quality can be assessed are: - Correctness: factual agreement of the data with the properties of the real world object that it represents. - Consistency: agreement of several versions of the data related to the same real objects, which are stored in various information systems. - Completeness: complete existence of all values or attributes of a record that are necessary. - Actuality: agreement of the data at all times with the current status of the real object and adjustment of the data in a timely manner as soon as the real object has been changed. - Availability: the ability of the data user to access the data at the desired point in time.

Data quality Key Performance Indicators (Data quality KPIs)

A quantitative measure of data quality. A data quality measurement system measures the values for the quality of data at measurement points at a certain frequency of measurement. Data quality key performance indicators operationalize data quality dimensions. One example is the validation of a data element based on business rules.

External data

External data refers to any type of data that is captured, processed, and provided from outside the company. The major external data types include open, paid, shared and web data. Despite their increasing relevance, external data remain an untapped resource for most companies. External data can be used to complement internal data and help to improve advanced analysis, optimize business processes (e.g. with geolocation, weather, or traffic data), reduce internal data maintenance efforts (e.g. to enrich or validate internal data), and create new services. However, despite their increasing relevance, external data remain an untapped resource for most companies.

M

Master data

Master Data is the most fundamental enterprise data type. Master data represent core business objects (e.g. customers, suppliers, or products) which are agreed upon and shared across the enterprise. They remain largely unaltered and are often referenced and reused in business document and data analysis. They must be unambiguously identifiable and interpretable across the entire organization (i.e., across organizational departments, divisions, and units).

Master Data management

All of the activities, methods and (IT) tools for modeling, managing and providing master data as well as its data quality management. The goal is to provide and ensure a company-wide truth about the core business objects (single source of truth) and thereby to support data users in various business processes throughout the company.

Metadata

Metadata is »data about data«. This means that metadata describes the properties of other data. Typically, metadata enables retrieval and maintenance of »data containers« (e.g., documents or files) by means of identifying, classifying or descriptive attributes. Metadata helps an organization understand its data and contributes to the ability to process, maintain, integrate, secure, audit, and govern it. Common metadata attributes include context (i.e. the environment in which data is living), terminology (i.e. definitions and descriptions), administrative information (i.e. when the data have been created and by whom) and governance (i.e. ownership and level of confidentiality).

People, roles and responsibilities

In the CDQ Data Excellence Model, the people, roles, and responsibilities design area defines the culture, organization, roles, boards, and interactions for data management. As data is generated, managed, and used in many different parts of an organization, a dedicated data management organization supports the orchestration and alignment of enterprise-wide data management activities. This is of particular importance as data management involves many different parts of the enterprise. Consequently, data can only be managed consistently if ownership and responsibilities are assigned and trained and when all employees have a data-driven mindset.

Personal data

From a regulatory perspective, personal data can be defined as “data enabling direct or indirect identification of a single physical person, data that is specific to a single physical person without enabling identification, data that can be linked to a physical person, data regarding which anonymization techniques cannot completely mitigate the risk of re-identification” (Debet et al. 2015). From a practical perspective, most companies collect personal data about their customers, employees, suppliers and vendors. A particular area of concern typically are customer data that can be defined as “a set of data that represents and is associated with the identity, activities and service offering associated with a unique individual” (Tapsell et al. 2018).

Q

R

Reference data

Reference data is used to characterize, categorize, validate or constrain other data. The most basic reference data are codes or key value lists, but they can also be more complex and incorporate hierarchies or vocabularies. Reference data can be defined and created internally (e.g., customer classifications, product groups) or received from external sources (e.g., country or currency codes defined by ISO standards, product classifications defined by e-commerce standards).

Regulation

A regulation is a document written in natural language containing a set of guidelines specifying constraints and preferences pertaining to the desired structure and behavior of an enterprise. Examples of regulations are a law (e.g., the General Data Protection Regulation - GDPR), a standardization document, a contract, etc. A regulation specifies the domain elements it applies to and oftentimes has implications for data management.

Regulatory guideline

A regulatory guideline specifies the expected behavior and structure on enterprise domain elements. It additionally defines tolerated and non-tolerated deviations from the ideal behavior and structure, and also defines the possible exceptional cases. A regulation may also specify how the enterprise ought to or may react to deviations from ideal behavior and structure.

T

Transactional data

Transactional data is created by business processes. It documents an important business event or the result of a business transaction. Transactional data often references master data, but in contrast to master data, it naturally changes during its lifecycle (e.g. status changes). Furthermore, the volume of transactional data (e.g. number of sales orders) increases with ongoing business activity. Transaction data typically occurs in invoices, purchase orders, or delivery notes.
