The Downside of Tool Autonomy

This editorial was originally published on January 31, 2019. It is being re-run as Steve is on sabbatical.

I am a big believer in letting teams of people work in a way that allows them some autonomy to solve a problem. I think this is especially important in the software world, where developers need to experiment and learn from the new ideas that they investigate. They need to be able to try new techniques, technologies, and platforms. Yes, that includes NoSQL data stores.

At the same time, this can lead to developers becoming captivated by new tools and techniques, all of which are good for advancing skills and code maturity, but can also lead to a very disparate environment where there are no best of breed solutions, or no standards for writing features. As the number of developers grow, this also raises the bar for each individual to know and understand more languages or technologies.

While I do think it's easy to pick up logic and syntax, when writing production code, we want to ensure we're optimizing the way we work. The way in which we might write some code when we start with a new API, SDK, language, etc. is often not the way we'd write that code after a year or experience. At least, I hope it's not the same way. There are nuances, tips, and tricks in how to better structure code that we learn as our experience grows.

When I was at the Redgate Software office last year, I noticed that there was a short article posted on our internal blog. This noted that there is a set list of tools and technologies to use when building our products. This isn't intended to be a long term immutable list, and the post noted that other choices are possible, but we want to avoid an unending growing list of tools when we have identified there is a good tool in a space. There is an approval process to propose and new tool and explain why it really is needed.

At Redgate, we're pretty flexible and open, so I'm sure this isn't a tough process. However it does prevent every developer from implementing their special little code into a project. We've had people use various different data stores, different types of web technologies, and it becomes a maintenance issue over time. Even the VB.NET component we used for years at SQLServerCentral caused headaches as there wasn't any experience in the company in this language.

I think it's worth having some light overview that ensures an organization isn't adding technology just for the sake of making one or two developers happy. There is a finite amount of time to spend learning and growing, and while it's important that technology workers do this, we also want to developer more experience and expertise in a few areas. Limiting tools and technologies helps preserve a balance that allows for growth, but ensures the expansion isn't unchecked.

Removing the Square Bracket Decorations with SQL Prompt

Additional Articles from Redgate

If you avoid illegal characters and reserved words in your identifiers, you'll rarely need delimiters. Sadly, SSMS applies square bracket delimiters indiscriminately, as a precaution, when generating build scripts. Phil Factor provides a handy function that adds quoted delimiters only where they are really needed and then sits back and lets SQL Prompt strip out any extraneous square brackets, in a flash.

SQL Server Transaction Log Management eBook Download

Free eBook: SQL Server Transaction Log Management

Press Release from Redgate

When a SQL Server database is operating smoothly and performing well, there is no need to be particularly aware of the transaction log, beyond ensuring that every database has an appropriate backup regime and restore plan in place. When things go wrong, however, a DBA's reputation depends on a deeper understanding of the transaction log, both what it does, and how it works.

  Question of the Day

Today's question (by Steve Jones - SSC Editor):

 

Changing the Data Frame

I have this data frame in R:
> fantasy.playoffs
                Team  Score           Opp
1 Way0utwest Cowboys 135.40          
2         SSC Ravens  66.26 Green Machine
3              Ditka  85.20          
4   Orange Engineers 111.52     Mexicanos
I then run this:
> fantasy.playoffs$OppScore <- c(NA, 66.26, NA, 111.52)
What happens?

  Yesterday's Question of the Day (by Steve Jones - SSC Editor)

The Login Types

In the sys.server_principals DMV, there is a type that corresponds to the type of principal stored in a row. There are SQL logins, Windows Logins, Windows Groups, Server Roles, and two other types. What are they?

Answer: logins mapped to certificates or logins mapped to asymmetric keys

Explanation: These are the types:

  • S = SQL login
  • U = Windows login
  • G = Windows group
  • R = Server role
  • C = Login mapped to a certificate
  • K = Login mapped to an asymmetric key

Ref: sys.server_principals - https://docs.microsoft.com/en-us/sql/relational-databases/system-catalog-views/sys-server-principals-transact-sql?view=sql-server-ver15

Auditing logins, logoffs, better way to do it in 2017? - A bit of history - When the company I am doing work for implemented SOX practices about a decade ago, one of the things that came out was that for certain "critical" databases, all logins (and logoffs) were to be tracked, which program was used to connect, which workstation, os user and database account.  At […]

SQL Server 2016 - Development and T-SQL
Surprised that Row_Number() has better performance than IDENTITY - I was doing some testing to see if it's more efficient to use an identity column or to use ROW_NUMBER() to simulate a unique ID for the result set.  My thinking was that ROW_NUMBER() would need to do some type of evaluation of the result set in order to assign the value where IDENTITY would […]

Why is this query slow? - #pastetheplan https://www.brentozar.com/pastetheplan/?id=SJF21m0lU I'm trying to figure out what's causing this query (part of a stored procedure) to be so slow. The NOLOCK hints were an earlier attempt to stop deadlocks, I'm guessing they are likely no longer necessary. I did add an index that helped a ton, but this is still pretty slow and I'm […]
