RDBMS vs. XML: Comparing the Technologies

Relational Database Management Systems (RDBMS) and Extensible Markup Language (XML) use very different technologies. This presentation will compare and contrast XMLS vs. RDBMS. Many of the differences between them are quite clear, and their advantages and disadvantages are obvious. However, that doesn't necessarily make it easy to choose between the two, as trade-offs will always exist. I have worked extensively in both technologies in a variety of corporate environments. In this presentation, I will identify the principle differences and similarities so that you can better understand each one, and enable you to make better architectural decisions in the future.

  • What is XML from the data practitioner's view?
  • The basic assumptions for relational data
  • Relational meta data schemas
  • XML meta data schemas
  • Relational architecture vs. XML architecture
  • What relational is really good for
  • What XML is really good for
  • Querying XML vs. querying relational
  • Managing change (flexibility) for relational vs. XML
  • Cost considerations
  • Comparing data integrity
  • What do I do now?

David Plotkin is the Manager of Data Quality for Wells Fargo Consumer Credit Group, one of the fastest growing companies in Wells Fargo. He has been implementing both procedural and object-oriented systems for over 15 years, and built Metadata management environments in four companies, including the implementation of several corporate repositories. He was involved in the complete recreation of Longs pharmacy system using object-oriented technology, including CASE tools, code generation and database generation from models, synchronizing the effort with a third-party software package, and implementing the Metadata management initiative. The effort includes a business rules-driven approach, with the capture of business rules, as well as the automated implementation of parameter-driven business rules. He also worked on Longs' E-CRM initiative, which included an operational data store, electronic bus, XML messaging and data cleansing. He is currently implementing a corporate metadata repository at Wells Fargo and is an active participant on the newly created Metadata council.



Your annual SF DAMA renewal invoices should be emailed to all individual members and our corporate contact in early August. We are excited that this year you will have the option of using PayPal for the payment as well as our usual acceptance of checks and paper credit card payments. The use of PayPal will greatly enhance our collection and record-keeping processes, as well as making it easier for you to pay. The fees are unchanged from last year: $65 for individuals and $200 for corporate memberships.

We are in fairly good shape right now with speakers for August, Sept, Oct, and Dec already lined up. We need someone for our November speaker and then monthly speakers for Feb through Nov 2005. So, the job is fairly easy to start, then it gets more demanding once we get into next year.

Some things to consider if you are interested in becoming the SFDAMA Program Director.

  • Do you have any ideas on they general types of programs you would like to create?
  • Do you prefer member speakers versus vendor presentations?
  • How about a vendor fair, or tool bake-off ?
  • Should be have a theme for a series of meetings or should be just pick whomever we can line up?
  • Are you able to attend most of the meetings?
  • Are you comfortable introducing the speaker and maybe leading a door prize drawing at the end of the meeting?
  • Can you stay for lunch? (We normally buy lunch for the speaker, but the cost of your lunch is not included.

There are several benefits associated with the position:

  • You will get to work with a great bunch of fellow board members.
  • You get a free dinner at each board meeting (normally in downtown Oakland, every 3 months).
  • You get free admission to our DAMA Day.
