The complex data modeling research network carries out its role by organizing open and closed online seminars, and reading groups (see here for more details).
For complex databases, it is usually valuable to create a top-level data model with lower-level subject area models. It is important to try to establish a glossary of terms covering descriptions of the most important tables, attributes and reference data.
Data model is a conceptual representation of data structures required for a database and is very powerful in expressing and communicating the business requirements (learn data modeling). It visually represents the nature of data, business rules that are applicable to data, and how it will be organized in the database.

In this paper we propose a logical data model for complex data. Our proposal extends the relational model by using abstract data types for domains specification.
The model is classified as “high-level” because it does not require detailed information about the data. It is called a “logical model” because it pr o-vides a conceptual understanding of the data and as opposed to actually defining the way the data will be stored in a database (which is referred to as the “phys ical” model).
While complex data types violate the most important rule of normal forms (atomic columns); much of the traditional teachings of dimensional data modeling broke several of these rules as anyway. With a bit of common sense and caution; complex data types can be extremely powerful in a modern data warehouse.

Used to model data in a systematic and proper manner, data modelling techniques helps companies to manage data as a valuable resource. It, therefore, goes without saying that data modelling standards are essential requirements for companies that conduct projects, where data has to be analysed and defined in a particular manner.
The model proposed by the authors is composed of a fact, of multiple dimensions and of as many.
Data modeling defines the structure in which data is interpreted and used by different entities in the organization. Often data is stored in different locations, and the volume that needs to be analyzed is exceptionally high. And, that’s what makes data modeling one of the most critical aspects of any bi or analytics project.

Data modeling is a processused to define and analyze data requirementsneeded to support the business processeswithin the scope of corresponding information systems in organizations.
Data models start out simple and grow, with no-payload joins frequently getting payloads later. If you start with a descriptive entity name, you won't have to change the name later. Ideally, the join entity would have its own natural (possibly single word) name in the business domain.
The data model is a collection of concepts or notations for describing data, data relationships, data semantics and data constraints. Most data models also include a set of basic operations for manipulating data in the database. Degrees of data abstraction in this section we will look at the database design process in terms of specificity.
What is data modeling? data modeling is a technique of applying mythology and algorithms to convert data into a useful form. The process converts complex software design into a simple easy to understand diagram with data flows.
Complex data necessitates additional work to prepare and model the data before it is “ripe” for analysis and visualization. Hence it is important to understand the current complexity of your data, and its potential complexity in the future, to assess whether your business intelligence project will be up to the task.
It uncovers complex relationships among data sets and variables, unobtainable through traditional practitioners and methods.
The conceptual data model should be used to organize and define concepts and rules. Typically, business stakeholders and data architects will create such a model to convey what a system contains. In contrast, the logical data models and physical data models are concerned with how such systems should be implemented.
Or it can be more complex, with multiple tables that use different combinations of relationships, joins, and unions.
