It’s a good point. I think I’ll take the existing data and performance test all suggested solutions. At the first glance EAV seems a little problematic since I can’t imagine how a search with 40 criteria would look. The answer might lie within symcbean’s answer, but I’m really not that good at SQL to understand it without some research.
Once the change has been implemented successfully, it is promoted to pre-production environment where in acceptance testing is performed and after the acceptance tests succeed it is deployed into production.
Using numbers instead of strings for representing status might speed up the database operations. For example, If user with id 1 has sent a request to user with id 2, action user id will be 1. So, the user who sent the friend request will be user 1. If user id 2 has blocked user id 3, then user id 2 will be the action user id. The user id 2 has blocked user id 3. Following is a sample screenshot of the inserted user relationship data. Following is a sample relationship table data Sample relationship table data Friend Request Inserting a new Friend request.
Friend request sent by user 1 to user 2. Once a record is inserted in the relationship table, a friend request or a relationship has been established between the two users. Accepting friend request sent to user 2 by user 1. If the result returns a row, then the users are friends. Here user 1 is the logged in user.

Dependency between the database and external applications make database refactoring a challenge.
This is my recommendation: 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.
How to Create a Dating App That Meets User Expectations
October 29, People love to communicate. We often joke that any software system always evolves into a messaging system. This article will explain the system requirements and step by step approach to design a data model for a messaging system. Our system also allows one to send messages to a user group. User groups can obviously be formed on some parameters like access privileges, geographical location of users, etc.

Thanked 0 Times in 0 Posts Designing Database for web application similar to dating website I’m creating a Facebook web application which functions in a similar way to a dating website, by getting users to provide information about themselves and information about their preferences in a matching user. I am creating the database for this and have the following design in mind: Contains the information about the users using their FB ID as the primary key. Contains the information about the preferences that the user wants.
There are going to be approximately 20 fields which the user can specify a preference in but all of them will be optional. I am unsure about the best way to structure my “preferences” table and I currently have two ideas: Use a foreign key of the facebook ID and have a new column for each field which can be matched on. A problem which I can see is that there will be a lot of “null” values in the database for fields which a value has not been specified. Do “null” values in a database occupy space or cause any other problems?
Use a foreign key of facebook ID again, but in the next two columns use a key-value pair approach – so one column would contain an ID for a user preference and the other would contain a value for it. For each user preference I would have a record with structure:

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.
The same principle was applied to the database schema as well where it was considered to be derived out of the software requirements which were in turn developed by collaboration between the customer, end-users, business analysts, etc. This approach proved to be cumbersome because as time progressed, the redundancies in the existing database schema in the form of unused rows or columns were evident. This redundancy along with data quality problems went on to become a costly affair.
It was concluded that the practice of not having design interleaved with construction and testing was highly inefficient. Evolutionary database design aims to construct the database schema over the course of the project instead of building the entire database schema at the beginning of the project. This method of database design can capture and deal effectively with the changing requirements of projects.
