I have expertise in modeling domains at a conceptual. logical and physical level. At the conceptual level, I can identify entities and the relationships among them. At the logical level I can identify attributes of entities. At the physical level I have the skills needed to assign datatypes to each attribute, and to identify foreign key columns and indexes.
In the process of database design I have used normalization up to the 3rd normal form. Where the application needed quick data retrieval I have relaxed the normalization to the desired extent.
I have performed the process of modeling up to the step of creating physical databases that act as repositories for web and mobile applications.
