From the first bullet point, you can see I have no idea whether such design is intentional or simply a mistake. Primary key could take an arbitrary number. The name cannot begin with pg_, as such names are reserved for system schemas. At this point, the role and its assigned privileges are assigned to the Fiber schema.

We moved the address table to the public schema, and replaced it with a view in each of the client schemas.

  • Data Governance and Data Modeling
    Casey Gwozdz Data Governance and Data Modeling Governing Data Definition . Data Governance and Data Modeling – August 2016 | 1 SECTION 1 INTRODUCTION Many years ago, a school teacher named Robert Cawdrey had a very Introduction interesting idea. In his society, there was an explosion of international commerce and many new words were being developed for the English Enabling understanding language. Also, literacy among English speaking people was becoming more and collaboration and more widespread. It was becoming quite a challenge to help folks through a common understand and use the English language. Robert Cawdrey thought to put vocabulary. together a list of words in a specific format with a list of abbreviations signifying the word origin along with a definition for the word to help promote understanding and word usage among English speaking people. So, after years of effort, Robert Cawdrey is credited with publishing the first dictionary of the English language in 1604, entitled “A Table Alphabeticall” (at least according to the internet). Since then, virtually all languages provide a standardized format for explaining and using words in their respective languages to aid in understanding and intended meaning in order to increase better communication with each other. Skip forward a few centuries, and it seems we have a similar challenge in today’s corporate computerized application business system society. More and more employees are becoming “computer savvy” with access to tools related to e-mail communications, spreadsheets, documents, etc. These tools even have dictionaries imbedded for spell checking and grammar review to help improve communication. However, when it comes to developing an understanding of the vast amounts of data stored in our numerous business application system investments today, employees really have a challenge.
