In memory datawarehouse

Technique in which the data warehouse is fully or partially loaded into the internal memory of the server. Mainly aims to process data and make it available more quickly.

Increment (INC)

A step, for example in a process or in the field of application development. By implementing something step by step, the entire process is more manageable and easier to control.

Incremental load

Loading the data modified in the source systems into the data warehouse.


Providing a collection of identifiable sequential characteristics. By indexing data, it can be found faster and easier.

Indicatoren (IND)

INK model

INK stands for ‘Institute of Dutch Quality’, an initiative of the Ministry of Economic Affairs established in 1991. The INK model, or INK management model, serves to make quality assurance and quality management measurable and manageable.


Inserting rows of data into a database. This usually involves a check to determine whether the record to be inserted is not already present in the table. See also: ‘append’, where this check is not performed.


A collection of related facts in a database. The related facts represent a unique appearance. For example, an order can be an instance, while the ordered product, quantity and price are the facts. Also used as a synonym for object in the object oriented terminology.


A positive or negative, but always an integer number. A very common data type.


Term used to indicate that a particular technique, tool or solution consists of an efficient combination of different parts. Often an integrated interface is used.

Integration competency centre (ICC)

A knowledge-driven body with both business and IT skills that can execute data integration projects quickly and cost-effectively based on best practices.

Intelligent database

A database that contains both shared logic and shared data and automatically invokes that logic when the database is accessed. An intelligent database works in particular with Artificial Intelligence, a method in which the most relevant information is offered to users in the interaction with users. This is in contrast to traditional databases where simple questions from a user with …

Inverted file indexes

A technique for more efficient access to data in an ad-hoc reporting or analysis environment. By placing all values in an indexed list, they can be accessed and used in any combination.
