Although XML use is a new activity, the creation of meta-data, schemas, and especially DTDs is an old, well-practiced art The design and development of an XML document and its meta-data parallels the design methodology used by data analysts to create data models and to design database architectures DTDs have been around in SGML development activities for around thirty years The combined experience of expert SGML developers and mature database designers has resulted in many good guidelines, rulesof-thumb, and best practices that can apply to meta-data, schemas, and DTD development activities First, before going through a long development on a project, carefully spec out the requirements and generate a data model In fact, use this approach even for a small prototype to avoid those horror stories of a prototype being put into a production environment and then breaking during business critical tasks There is a story about an R&D engineer, who, by the gift of gab, got hold of the ear of the systems engineering vice president (VP) and explained how great XML, Java, and Web technology were for interoperability This engineer, a very articulate incompetent, was able to con a few million dollars out of the VP to develop a prototype Web interface to a cost-and-schedule database The prototype took 6 months to develop under the engineer s random, unwritten directions and it appeared to work marvelously The VP was overwhelmed and directed the engineer to develop an enterprise-wide multidatabase production-quality Web interface If either the engineer or the VP had any knowledge of computers or information technology, they would have sought the experience of a data analyst The data analyst would have purchased a $40 book (not this one) about Web-based database interfaces, popped the accompanying CD into a computer, and in less than a week, for less than $100, he would have prototyped a terrific interface Then when the VP ordered an enterprise-wide interface in 6 months, the analyst would have laughed The data analyst would have laughed because you cannot scale a cobbled-together prototype into a corporate-ready interface The engineer

wasted millions of dollars and never could figure out why the resulting large interface would never work The project was taken away from R&D and given to an Information Technology (IT) architect, who scrapped the prototype and started from scratch In this case, the R&D engineer did not have the business sense to accept the sunken costs of the prototype and kept trying to scale it up But trying to scale a quick and dirty prototype is like trying to use an average frying pan to make scrambled eggs for a thousand people It simply will not scale up in the time required The lesson here is that if you develop a quick and dirty XML prototype, scrap it and start over when you plan for the production phase The IT architect s side of the story is an interesting contrast The IT architect went through a disciplined three-phase design: 1 Gathered requirements and built a conceptual architecture, which was used to gain consensus with all the stakeholders; 2 Designed a logical architecture that depicted how all the general pieces went together, how the communications worked, what the general data element types were, and where the gaps occurred The IT architect reviewed this logical architecture with the stake-holders, negotiated changes in the requirements, and got buy-off on this phase; 3 Filled in all the gaps, developed the DTDs, designed the interfaces, and implemented a physical architecture While the interface had plenty of bugs, the IT architect could backtrack to the logical architecture to locate where the reasoning was incorrect With a few changes and a few iterations, the system worked Even with the legacy problems inherited from the R&D engineer, the IT architect was able to put a working enterprise-wide database interface up and running in just under 6 months, and for less than one fourth the cost of the engineer s prototype fiasco The lesson here is that disciplined design is the key to XML implementation success In developing a set of DTDs or XML documents, gather the requirements, build a logical model of the data element types, and then build a prototype of XML tags and the physical implementation Use production-quality design and development, then iterate through the implementation to work out the bugs and get it right When designing schemas or DTDs, be careful of inherited changes In good programming, developers commonly place a variable where it can be
