October 29, People love to communicate. We often joke that any software system always evolves into a messaging system.

Create one ‘Attributes’ table that stores all the different “questions” “What is your hair color”,”What is your eye color”,”What are you favorite activities”, etc. This table needs an ID field and a text field to hold the question Create an “Responses” table that stores the choices for each ‘Attribute’. This table needs an int field to join to the ID of the Attributes table and a text field to hold the responses to the questions As you can see, the responses for all questions will be in this table.
Create a “user responses” table to store the answers for each of the users. This table will have an int field to join to the user ID and an int field to join to the responses table. Once those are set up, to find all the responses a user entered for his or her profile, create a query to select the user, join it to the “user responses” table and join the “user responses” table to the “Responses table”. The user table holds the user name, the user responses table holds the answers, and the responses table hold the text of the answers.
This method is very flexible because to add a question, you just need to add a record to the “Attributes” table and add the responses for the question to the the “Responses” table. Also, each question can be answered with multiple answers. Additionally, this method is very flexible in the different queries you can create The only issue with this method is that you need to handle text answers separately; this method only works for multiple choice answers.
However, using this method and mixing it with a text answer method should not be difficult. Let me know if you have any questions!

History[ edit ] After using the waterfall model for a long time, the software industry has witnessed a rise in adoption of agile methods for software development. These methods are designed to support sporadic changes in contrast to waterfall design technique. An important part of this approach is iterative development , where the entire software life-cycle is run multiple times during the life of a project. Every iteration witnesses the complete software development life cycle despite the iterations being of short duration that can vary between weeks to a few months.

That way you can make informed decisions about adapting the schema to resolve specific performance problems, rather than guessing. You definitely should go down the 2 table route. This will significantly reduce the amount of storage, code complexity, and the effort to changing the system to add new attributes. Assuming that each attribute can be represented by an Ordinal number , and that you’re only looking for symmetrical matches i. At a simple level, the query to find suitable matches may be very expensive.
Effectively you are looking for nodes within the same proximity in a N-dimensional space, unfortunately most relational databases aren’t really setup for this kind of operation I believe PostgreSQL has support for this. So most people would probably start with something like: Applying a little heurisitics and you could get a very effective query:
