Overview of the transformation from a relational database to a data target
Versie | 1.0 | Creatie datum | 02-05-2021 |
Data target based on a standardized data model. Based on this model and the included data entities one or more interfaces can be implemented for the consumers.
Extract functionality for receiving data from the source systems. This has a XML format and the source is either a webservice or a XML file. The data is extracted and prepared to be transformed
Load functionality for transferring the data to a data target and load it there. This can either be an ETL process or the implementation in a message handler
The logfical or conceptual model is abstract in nature and is therefore independent from the implementation platform. In most cases this model must be readable for non IT stakeholderrs.
For the transformation of source to target datamodels a description of the data elements has to be modeled.
Physical model for the description of a technical implementatin model. This is platform specfic and is used for the creation of SQL DDL and ETL scripts and eventually for technical documentation.
Transformation functionality for transforming the data content from a (application) specific datamodel to a generic datamodel based on a standardized datamodel (see the service diagrams). This can be impllemented either in an ETL transform process or in a message handler for example in a service bus.
Workflow management for the scheduling and iteration of transformation tasks
Data entities saved in a relational (staging) database
Transformation of relational data entities (stored in a relational database) to the standardized data target.
Transformation function from the specific source data model to the standardized target data model. This can be a model or a protocol transformation.
Often this transformation is divided in sub steps and these sub steps will be analyzed and modeled in the architecture of a specific data pipe implementation and components
