Apr 9, 2018 // by //, //When you have been a data modeler for redacted decades, you learn to see the world through data modeler eyes. Everything seems to be a data modeling question.I was with a client for lunch one day and we asked the server “What do you have on tap?” She was gone quite a long time, but came back and said “Beer.” It turned out she was right. But her answer was not that helpful. Why is an Expert Asking Us What a Data Model Is?One of the odd parts of every new project I have to deal with is getting everyone to understand that the question “Can you help us with a data model” results in me asking. “What do you mean by data model?” That’s right, I have to ask team members what a data model is.
You’d think experts would know better.I have to do this because it seems like everyone has a different definition. For most DBAs, they want a reverse-engineered image of a production database. For a business user, data modeling that results in documentation about all the questions, answers and decisions were made.
For a developer a specification of something they can build upon. An executive wants a high-level view of the data concepts a specific project will be addressing so she can approve scope and budgets. A data scientist wants a consolidated view of both the physical data objects available to him and a logical definition of what they are. Finally, a data modeler wants a list of previously modeled entities so that she doesn’t have start from scratch on every project.It’s likely that every role in the organization wants a different data model with a different set of metadata. It’s also why we need to have a discussion about. Even that set of terms has differing definitions. That’s nearly unforgivable given that we data modelers preach that we should use consistent definitions.
(Note from author: this one bit led to one of the longer threads on LinkedIn that has ever been discussed about one of my posts. Some of the comments are not fit for work.) Then to make this even more complex, we need to discuss the as well. Simple Tools Don’t Work Well For Complex Data Model QuestionsThis is why using native database tools aren’t good enough to solve all those needs.
This is why a simple drawing tool isn’t enough. What an enterprise needs are tools that can author, design, and present all those types of data models without creating duplicate copies of those data concepts. It’s also why a data modeler needs to ask the question: What do.you. mean by data model? You need to ask your team members what they are expecting before you start working.
You may need to negotiate priorities or formats. You may need to create separate views of your models. That’s wonderful, though, to deliver what they need from your data models.
It’s all good.It’s not that we modelers don’t know the 100+ possible answers to that question. It’s that we know there are 100+ answers.It’s not that we modelers don’t know the 100+ possible answers to that question. It’s that we know there are 100+ answers. That’s what data modeling is after all: getting to the right answer for this requirement.Note: This post is an updated version of one posted to community.embarcadero.com in 2015. Jan 30, 2014 // by //, //I’ve been using Parallels Desktop for Mac ever since I purchased my MacBook Air a couple of years a go. This virtualization software lets me run Windows on my Mac so that I can use all the data modeling and database tools I need.Just this week, Parallels asked if I wanted to try out a new product,. (So as to not confuse this with Microsoft Access, I’m going to use the full name of the product in this post.) This product lets me use desktop applications as if they were built for the iPad.
It works by installing an app on my iPad, plus a service on my desktops (Windows or Mac). Then when I want to run a “real” application from one of my computers, I can fire up the app on my iPad and start using it.
And it pretty much works.I’m hosting a contest to give away five, yes FIVE, subscriptions for this product. Details at the bottom of this post.
Isn’t This the Same as Remoting In to Your Desktop?I’m betting right now you’re thinking: “I have RDP or some other remote app and I can use that, but it’s a real pain to navigate around on an iPad.” Yes, yes it is. I’ve tried several remoting apps over the last few years. I usually use them when I am out of my office and have to grab a file or fix something without having to find a computer to use a real keyboard and mouse. And it’s painful.

Very painful.What’s different about Parallels Access is that they’ve added iOS-like gestures and interactions to make it feel like the application you are running is a native iPad app. Instead of telling you about it, let me show you a few. Dec 24, 2013 // by //, //Dear Santa,My friend and debate foe victim Thomas LaRock ( ) sent you some for organizations who need your help. That got me thinking, so I made a list, too.
I checked it three times because I’m thorough like that. I’ve based this list on observations and data I’ve collected over the last year. Much like you do. Except I didn’t use that creepy shelf elf guy.Just in case you didn’t collect enough data, or it got lost in some hard drive failure:For Twitter: A way to restore those 20k Tweets of mine they lost a few years ago.
Oh, waitprobably better that they aren’t part of the firehose any more.For Data Modeling tool vendors: A copy of my multi-volume set of enhancement requests for supporting new database and datastore types. It’s nearly 2014; it’s time we data architects were able to do our job regardless of the target technology.For the NoSQL Community: A love of data so strong that they can tolerate the mere mention of relational database solutions when appropriate.For Microsoft: A brilliant new name for.
I can’t keep saying that in my presentations. Even WASD is difficult.For Oracle, IBM, and Sybase users: A community as active and as those in the SQL community.For United Airlines: A set of laminated copies for each employee of your Star Alliance agreement to remind you that 125k flyers do indeed get perks on your airline.

Tell them to get cracking.For NASA: ThatFor Justin Bieber: US citizenship and a ranch in SoCal. And a plane ticket. No monkeys.For Rob Ford: NULL. Not even coal.For my readers and their customers: A year in which their data is much loved, in the right place, at the right time, with the right granularity and the right integrity. Or World Peace.
Probably easier.Love,(Kitty is my Starbucks name. I figure Santa knows that already.).
