developer, thoughtworker, data architect and data specialist. in all new development and sometimes during legacy codebase modernization, developers tend to add code quality checks and static. id generation with orm's table, sequence or identity strategy. data into tables with lots of customization. in the example shown below, i’m loading zip code data in todays environment, identity theft and related crimes are frequent and common place. most of these incidents take place because our development shops, developers are not allowed to access the database schema directly, and are not allowed to create tables, indexes, views. using rake and activerecord to generate boilerplate db code. be implemented using triggers. why have triggers? when the application can do the updating, this is a good argument, but like all application databases eventually other users, applications and scripts will get access to the applications database and end up wanting to read from the database and write to the database. during these times its better to have triggers updating the data independent of the application to ensure audit columns and other columns are updated with appropriate values. we can implement the triggers either by hand coding or by generating them using the database metadata and some build time scripting. hand coding these triggers is mundane work and error prone, especially when we need to add a new column that needs to added to all the triggers.. 8 techniques for testing migration of data from legacy systems. many of the projects we end up working on are replacing existing systems with existing data either wholly or in part. in all of the above projects we end up writing data migration or data conversion code to move the data from legacy systems to the new systems. many stake holders of the project such as business users, project managers, business an*lysts really care about the data conversion scripts and © 2018 © pramod sadalage，please give source attribution if you like to quote or reproduce.
