Async, no tracking and profiling A brief history of. Microsoft put in a much more serious effort with Entity Framework. As with a lot of Microsoft products, the early versions were inferior to the community-supported ones. But the technology rapidly improved, and by version 4 Entity Framework was, in my opinion, at least as good as NHibernate. For a while, all was good in the Entity Framework world.

Dating Database Schema JDIQs mission is to publish high quality articles that make a significant and novel contribution to the field of data and information quality.. The relational model also allowed the content of the database to evolve without constant rewriting of links and pointers.

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.

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.

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”.

Image from Motion pictures Introduction Before you start reading this article let me confirm to you I am not a guru in database designing. The below 11 points are what I have learnt via projects, my own experiences, and my own reading. I personally think it has helped me a lot when it comes to DB designing. Any criticism is welcome.

I am tasked with designing a dating site in with VB using sql server as the database platform. I have not had a lot of advanced database design experience so I am hoping someone can help me out with this one. For each user there is a profile (some profile questions might be: nationality, education, age, eye color, etc, etc..).

This is important in many applications because direct table access is not allowed. Current builds of the Entity Framework support using stored procedures for inserting, updating, and deleting entities. We are actively working on supporting stored procedures for reading entities — this should be available in an upcoming build.

In this post, I cover the use of stored procedures for change processing: Readers unfamiliar with the ADO. NET Entity Framework Overview before proceeding — in this post, I assume you already have a working knowledge of Entity Framework basics, including conceptual models, mapping, and programming with Object Services. In addition to the overview, readers new to the Entity Framework may benefit from looking at the ADO. For clarity, the database and conceptual model I use are exceedingly simple, but they are sufficient to illustrate the key concepts involved in working with stored procedures in the Entity Framework.

This section describes the sample database, the conceptual model and its mapping to the database, and the client code used to manipulate entities with the ADO. At first, the operations on the entities will translate to direct insert, update, and delete statements against the tables. Logical Database Schema Our database is called ProductInventory and has tables that encapsulate product and category information.

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.

Here, user 1 is the logged in user.

For information on specifying character data types as literals, refer to Text Literals. You specify the database character set when you create your database. When you create a table with a CHAR column, you specify the column length as size optionally followed by a length qualifier. In the byte length semantics, size is the number of bytes to store in the column.

In the character length semantics, size is the number of code points in the database character set to store in the column.

In general, you shouldn’t sacrifice database integrity for performance. The first thing that I would do about this is to create a table with 1 mln rows of dummy data and test some typical queries on it, using a stress tool like ab. It will most probably turn out that it performs just fine – .

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. This is a design feature of feature dataset behavior; it’s not likely to change at least, it hasn’t changed in the past seven releases dating back to 9.

Feature datasets were never intended to be used as “folders” for organizing data. Their purpose has always been to permit cooperative editing across feature classes e. There are a number of significant performance issues with using feature datasets as logical organization tools, and documentation, training, user conference workshop slides, and forums are filled with exhortations to NOT use feature datasets for this purpose. I empathize with those who find organizing hundreds of tables in a flat RDBMS representation cumbersome, but that’s the paradigm for RDBMS access, established many moons ago, so it doesn’t seem to be changing either.

There is a means for isolating user data in Oracle geodatabases, but user-schema geodatabases are, IMHO, a treatment which is far worse than the disease.
