comment Is Business Intelligence (BI) the Right Job Title?
@TravisParks, a reporting specialist should be able to write a long SQL statement (with maybe 15-20 joins and 10 where conditions) that runs fast. Never hire anyone for a role like this who is not expert in performance tuning as reporting is often where the worst of the performance issues lie. In interviewing ask them how they would replace a correlated subquery to get the code to run faster. Another good question is to ask them what they don't like about SSIS (If they say nothing, they don't know SSIS very well.) Ask them how they would scrub data.

Oh and real BI people who are competent get paid as much or more than developers.

comment Is Business Intelligence (BI) the Right Job Title?
I am a Business Intelligence specialist and if they don't know SQL at the expert level, they are incompetent pure and simple. You cannot do SSIS packages or SSRS reports effectively witrhout knowing advanced SQL. Yes you can throw something together but it is likley that it will be incorrect and the people who are relying on the reports will not know it. These people are more than incompetent, they are dangerous to the organization as real world decisions are being based data provided through their incompetence.

comment Does dealing with legacy code help one evolve as a programmer?
@RossPatterson, since this is banking, yeah I hope they really do work correctly now. At anyrate if there are no tests, then the risk of making a change is huge in banking and writing unit tests to help you learn the system should be an easy sell.

It also helps you to understand taht the method you think they should have used was not available when the code was written.

comment Getting related foreign keys from parent entities
If you do denormalize, you need to maintain the client_id through triggers on all the relevant tables. It is the only way to ensure consistency no matter how the data is changed. (There is an exception for bulk inserts which can avoid triggers but peopel doing this type of thing generally know to reproduce the trigger code they are avoiding after inserting or updating the ten million records.)

comment What are some possible interactions between multiple bugs?
I would add that sometimes a particular bug may result from a poor understanding of a type of code and that poor understanding may be elsewhere. I'm thinking of things like failing to handle the case where a divisor turns out to be zero or someone who never handles nulls correctly. Each implementation may be a different formula or unrelated piece of code but the same fundamental misunderstanding of what to do is through the application. Sort of like Entropy sprinkler only the code isn't necessarily related except through the coder's misunderstanding of how things work.

comment Should we persist with an employee still writing bad code after many years?
I suspect this guy woud be absolutely flabbergasted to find out that his manager is thinking of firing him. Some people you just have to hit over the head with a plank and flat out tell them that they have to improve or they will be fired.

comment Stored Procedures a bad practice at one of worlds largest IT software consulting firms?
@MichaelKohne, I would say never in my experience. It depends on what segment of the industry you are in. In Enterpise systems it is rare to change database vendors. In the COTS world, it happens all the time or the design must account for multiple vendor possibilities. In the web world is somehwat divided depending on what the web site actually does and how critical the db is to the success of the site.

comment What kind of knowledge is needed to be a Financial Software Developer?
And if you are in any way shape or form dealing with money, you need to know about the accounting concept of internal controls because the developer needs to ensure the software has them and no one will mention them in the requirements. In other words, you should always be aware that your software should be making it difficult to commit fraud.

comment Requirements Analysis Communication
That would be a poor requirment. What about numbers that are appropriately stored as string data (say phone numbers) do you really want to convert them to a numeric so you can order them? Why would you sort dates by time only? Do you want 01/01/2013 22:00 to come after 06/03/2013 08:00?
