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. Thanks to everybody for their contribution. 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.

Data referenced by the BBC show a rise over five years of people reporting being raped on a first date by someone they met on a dating website or through a mobile app. If you want to build the next Tinder, you might even consider investing in some form of security checks for people who sign up for your dating app. If you have already attempted to use the existing Word Press API to access the data you need but have determined it"s not possible without accessing the database directly, Word Press provides the wpdb class to make this task easy.

The diagram below provides a visual overview of the Word Press database and the relations between the tables created during the Word Press standard installation.

How To Build An Online Dating Site, NoSQL Edition. This is part 2 in a series about the architecture of a general overview, see part Like a lot of people building websites today, I emerged from the s with a lot of experience building applications using the “traditional web stack”: Some sort of web server that accepts HTTP requests, issues SQL queries to an RDBMS.

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.

Have you ever had to create a new set of tables that is mostly redundant except for the dates in which the data occurs? If so, you may be in dire need of Effective Dating and not even know it. Effective Dating is a Design Pattern that recognizes that most data is only effective for a specific period of time. This is also referred to as"Temporal Database Design".

In the case of sales promotions, they usually have a start date and an end date, so you should take these into account in your design. This, in the simplest sense, is what Effective Dating is. However, as with many things,"the Devil is in the details", and in this case, it"s a really big Devil: I have seen entire sets of tables and processes that are completely redundant, existing only because the base tables were not Effectively Dated. One reason is that representing date-time data is fraught with many complications and pitfalls, so implementing it can be discouraging.

Another possible reason is that with all things database-related, once the initial decision is made to commit to a bad design it"s rather difficult, though not impossible, to undo its effects. If you"ve ever read up on this subject, you know how complicated it gets. What benefits do you get by properly expressing this data in an Effective Dating scenario? In this article I"m going to provide a clear, simple answer to this question and also lay the foundation for the later parts of this series of articles that explain what happens to Relational Databases when you introduce the concept of Effective Dating.

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. This system allows receivers to respond to the messages.

It also keeps track of who has read the message and who has not. In addition, the system has a built-in reminder mechanism that allows a sender to create a reminder, and then sends a reminder to all receivers accordingly. As its name suggests, it signifies the id of the creator of a message. Since there would always be one creator for a message, I keep this column in the message table only.

I have added this column to manage reminders on a message. I will explain more about this column later in this article. I would say the whole data model revolves around this table only.

This can cause multiple problems, including being unable to access certain objects, potentially accessing the wrong objects, and two users can even generate multiple copies of the same plan for the same query. Usually, this is easy to remedy - you go into Management Studio, right-click the user, and change the default schema through the UI. But what if you have hundreds of users, across all of your user databases, that should all have the same default schema?

Solution While it may sound weird, this is actually one of my favorite types of problems to solve. Even though I"m sure some folks out there would immediately think,"To the PowerShell! First, let"s understand where we need to get. Assume we have a system with a large number of users who should all have dbo as the default schema, and it is unknown how many of them currently have a different default schema.

The code we would need to use to switch them all to the same default schema would be: We can do that inline, like this:

First off, there"s only one database involved. Databases can have multiple user schemas, and each connection is to a schema in a database. User schemas can create multiple feature datasets, which are not equivalent to databases your problem description is very confusing in this regard, since"owner","user", and"database" seem to have different than the conventional definitions.

Each connection, in addition to all the tables that a given user can see, will see ALL the feature datasets in the geodatabase instance. This is because, unlike tables, feature datasets are artificial constructs in the SDE. There is no efficient way to determine the contents of a feature dataset before it is opened, so they are all listed unexploded , and upon open, if you do not have at least SELECT access to every table listed in the metadata, the object will show as empty.

A database schema represents the logical configuration of all or part of a relational database. It can exist both as a visual representation and as a set of formulas known as integrity constraints that govern a .

David Gries, Compiler Construction for Digital Computers Introduction When we as developers are learning new techniques, examples can be our own worst enemies. Tutorials are designed to be easy to understand, but at the same time they often reinforce lazy, inefficient, and even dangerous coding practices. Nowhere is this more common than in ADO. In this article we"re going to take a look at what it means to strongly-type objects from your database, and why despite the lack of examples, you will almost always want to do so in your applications.

Specifically, we will see how to create and use strongly-typed DataSets in Visual Studio As this article explores, strongly-typed DataSets offer a number of advantages over alternative, loosely-typed data access techniques and, with Visual Studio , creating and using strongly-typed DataSets has never been easier. Read on to learn more! If you are single, what type of person would you consider dating? You may have specific criteria wealthy and attractive or it might be short and vague living and breathing.

Whatever your qualifications are, you inevitably have a standard of some type that you use when you decide who to spend more time with. If you"re wise, a thoughtful list will save you from unnecessarily painful emotional trauma. You may find, for example, that a serious relationship with an alcoholic is a recipe for instability and unpredictability. Because forcing someone to change is as painful as it is ineffective, wisdom would dictate that you stop the relationship before it even starts.

Adding a non-alcoholic clause to your dating standard saves you heartache down the road, and allows you to focus your time and energy on better candidates.
