Data modeling is the act of exploring data-oriented structures. When building a database, data modeling implies the creation of a model for data within that database. Data models can be used for a variety of purposes, from high-level conceptual models to physical data models. VTC author, Gavin Powell, covers topics such as normalization and denormalization for relational data modeling, fact dimensional structures for data warehouse data modeling, and basic object data modeling for object databases. Powell also examines useful web sites and vendor software, such as Oracle database, for finding data modeling information. To being learning today, simply click on one of the Data Modeling lessons.

VTC: Beginners UML Tutorial
UML is a standard, visual modeling language that comes into play in all stages of the software development life cycle: modeling business processes, conceptualizing system functions, visualizing and documenting software artifacts, developing object-oriented software. In other words, UML is a language that allows the writing of a software system’s blueprint in a way that can be easily understood by various stakeholders, including business analysts, project managers, system and database architects, etc. This introduction, by VTC author and corporate trainer Nancy Conner, covers UML basics and goes into detail about the most common kinds of UML diagrams.

Design patterns let programmers avoid re-inventing the wheel. The original book (Design Patterns by the “Gang of Four”: Erich Gamma, Richard Helm, Ralph Johnson, and John Vlissides) was phenomenally successful. When the programmer faces a particular problem, all they have to do is to look up the correct matching design pattern and use it to implement the solution. In this tutorial VTC author Steve Holzner guides you through the most popular and useful design patterns, so you can begin incorporating them into your own code.
