"Data architects design, build, and maintain the systems that dictate how a company's data is collected and stored. Expect interviews to consist primarily of technical questions that will test your knowledge of engineering databases. Employers are often looking for candidates with degrees in data science, computer science, or another related field, as well as a knowledge of relevant database languages like SQL."
Explain the difference between MS Visio and IBM Rational Modeler (formerly called Rational Rose) ?
With Rational Modeler, one can keep different artifacts (use cases, activity & sequence diagrams, etc) in a package. This means it has more integrated approach since dependencies among different artifacts are reflected as compared to Visio that treats every artifact independent of other artifacts.
