Denodo Data Virtualization

Denodo is a Data Virtualization environment where the entire process of ETL is reduced to a configurable set of layers containing various views. These views depend on table definitions which reside in source systems. The upper layers of views should represent the business needs and are in need of solid data modeling. These upper layers of views in Denodo are like an interface. The most common usage is in a top-down design where you first define the fields and later associate the implementation(data) of the interface.

Fully Communication Oriented Information Modeling

The data modeling method "FCO-IM" is a successor of the well known method NIAM; both use natural language to assemble the model. The FCO-IM is an advanced data modeling method which allows more elegant models, capable of better model to model transformations, while remaining to be easily validated by the business and it's users.

Language and Modeling

Business people communicate using natural language without much thought about the fact that they do so. In IT, engineers invent computer languages to communicate with computers. Translating thought into computer languages goes a long way, but is never meant to be used by non technically equipped people, or business domain experts.

Zachman Framework

Information systems are meant to automate the repetetive tasks of the employees of your business. Systems administer data relevant to it's business owners and users (E.g.: people, places, things, events and reasons). Designing these systems requires lists of datamodels, proces models, database models, schemas and diagrams with object classes, procedures, documentation sets, and lots more.

System Design Cycle

CaseTalk as the conceptual modelling tool is for technical system developers somewhat difficult to place in the development life cycle. For this reason we'll show you a perspective which will firmly place its position in the cycle every IT related employee or consultant is part of.

Data warehousing tool support

In operational practice, data warehouses are big corporate databases that are continuously under development. This implies a dynamic increase of the complexity of the data. For controlling this complexity, a conceptual model driven approach is recommended in order to guarantee that the relation to the business environment can be validated at any moment.

Graphical Notation

The FCO-IM has many standards for diagramming, only the most common and widespread used symbols are explained here. In FCO-IM one recognises three main graphical objects: Facts, Objects, and Labels.

Unification of Concepts

A unification of concepts was presented at the "Trends in informationmodeling" seminar by Harm van der Lek. It illustrates the elegancy of the method FCO-IM by indicating a reduction of elements used in various data modeling methods.

Communication Oriented

The essence of Fully Communication Oriented Information Modeling (FCO-IM) is modeling the communication. Employees constantly communicate facts, for instance "Invoice 1238 has an invoice date 1-1-1950". FCO-IM models the communication of the facts. This article explains the importance of fact based modeling.

Model to Model transformation

A conceptual information model of the business is a great asset. It's a solid investment since it is technology independent. Since IT undergoes changes at an accelerating pace, the only real long lived asset is this information model.

FCO-IM History

Starting in 1992 the FCO-IM method and theory steadily emerged out of the method NIAM. Many articles, books, tools and research material have been made public during that time. In the attached article you may find a full chronological overview.

Information Architecture

Information architecture distinguishes different layers and compartments, each with specific models. These compartment are ordered and the models related. This article describes the compartments and models which are influenced by CaseTalk and the Fact Based Modeling.

NIAM

Nijssen developed a method for information modelling based upon the communication about a user's domain instead of the domain itself using natural language fact expressions. These crucial elements made NIAM unique compared to ER and other methods in that time upto now.

FCO-IM Principles

The FCO-IM method contains the following set of structural principles which are additional to the basic principles of NIAM, such as natural language, concrete examples, user interviews and prescription based information modelling.
