Applications ^ Data

Today's applications are powered by data, just like machines are powered by energy.
In this series of blogs, we will look at how applications use data, how data is organized and what effect it has on the evolution of functionality.
A professionally managed product will typically have this context:

  • The product itself: X-ray equipment, Surgery devices, Ultrasound machines, toothbrushes and so on.
  • A sales person would be in the process of getting a customer interested
  • A customer would need consumables - like a new brush
  • Many of these equipment produce images
  • A customer would own one or more equipment
  • A service engineer would service a set of equipment
  • A product will have parts that are replaceable
  • Spares would be stocked
In today's world, each of these aspects are supported through applications. Application experience is enhanced with data. How do we store and correlate the data, so that it's usable?

One way is to structure the data by modeling using Entities and Relationships.

How do we model an equipment and its expert as entities, and the relation between them? Read on to try relating an equipment to its expert.

Relationships in a Relational Database

Image
A Relational Database models data in the form of tables and relation between tables. Consider the following application: When a customer asks a question about an equipment, we want to connect to an expert who can answer. For example, an expert on Ultrasound is different from an expert on X-ray; and there are different experts in different countries. One way to model this data is to make a table with the equipment identifier and the contact of the expert. As you can see, there's a lot of redundancy; the expert's contact is replicated in multiple rows. Not only is this inefficient in terms of storage, but also multiple updates need to be done when there's a new expert. How could we solve this? Any identification we repeat will have the same redundancy. The answer is to remove redundancy - normalize the data. The best normalizations are the ones that reflect the real world. In this case, the equipment and the region are linked to the contact. So one way to organize th

Data Schema and Blobs

The schema gives the organization of data. It says what the data means. In the previous example, the 'contact' column had the contact of a person and not an ID. That's what is given by a schema, in addition to the table-structure itself. Often, changes in schema require expensive migration - not only in the database, but also all applications that are using the database. As we saw in the previous example, we needed to change the country to an economic zone, but all zones were not ready to move at once. How can we reduce the burden of migration? Let's examine a few ways: Build some wrappers over the database. So when the structure of the database changes, we can still convert back to the old data. Retain the country and relate it to the region in a separate table: In this way, whoever needs the country can refer to that, and whoever needs the region will access it. This is a clever way that relies on modeling like the real world. Change the organization of the

JavaScript data-types

JavaScript is a versatile language that's used in programming everything from web pages to servers and desktop applications. We will use this interactive tutorial  as a reference in our journey. JavaScript is different from the other languages we've seen here (C++, C#, Java), in that it doesn't have a compiler. The code is interpreted while running it. This brings us to a distinction in data-types as well. JavaScript doesn't fix the type of its variables. For example, this is a valid sequence for the interpreter: var x;           // x is undefined to start with x = 15;          // After this assignment, x is a Number x = "Phil";      // Here x becomes a String Many other fun things can happen with JavaScript data, as you can see here . What could be the use of such flexibility? Tell us what you feel below. Hint: Think of real-life arrays - like array of vehicles, array of chat messages, etc. Once you are done, let's step int
