Is there anything wrong with creating Couch DB views with null values?

问题 I've been doing a fair amount of work with Couch DB in my spare time recently and really enjoy using it. I find it to be much more flexible than using a relational database, but it's not without it's disadvantages. One big disadvantage is the lack of dynamic queries / view generation... So you have to do a fair amount of work in planning and justifying your views, as you can't put that logic into your application code as you might do with SQL. For example, I wrote a login scheme based on a

问题 Greetings, I'm building my personal website using php. My standard approach is to use MySQL as a database backend. I've been hearing a lot about document orienting databases and I'm wondering if these ( couchDB, mongoDB) might be a better option for me. I understand that a low traffic site such as my personal homepage isn't going to see massive improvements from running a different DB, but I appreciate "the little things". The database will primarily be holding textual data, such as comments

问题 I need to make some benchmarks on a small database (64MB) and I need to figure out what is the smartest way to fetch whole Mongo collection into python object with PyMongo?

Relations in Document-oriented database?

问题 I'm interested in document-oriented databases, and I'd like to play with MongoDB. So I started a fairly simple project (an issue tracker), but am having hard times thinking in a non-relational way. My problems: I have two objects that relate to each other (e.g. issue = {code:"asdf-11", title:"asdf", reporter:{username:"qwer", role:"manager"}} - here I have a user related to the issue). Should I create another document 'user' and reference it in 'issue' document by its id (like in relational

Designing record keys for document-oriented database - best practices

问题 Our team has started development of an application backed by Couchbase DB; for every one of us it's the first experience with a no-SQL database. We've started to define our entities and adopted the practice of using "type" prefixes, suggested by Couchbase manual: Entity "A": key: a#123 Entity "B": key: b#123 But we realized that we're getting confused with choosing the strategy for creating compound document keys. We use counters a lot, and they require their own documents. Our keys have

问题 NoSQL term has 4 categories. Key\value stores Document oriented Graph Column oriented. From my point of view all these data modeling has same definition, What are differences? Key\value database maintains data in structure like object in OOP. having access to data is base on unique key. Column oriented is an approach like key\value! But in key\value, you cant access to value by query. I mean, queries are key-based. Compare 1st & 2nd picture from 2 different categories. Document oriented

问题 Recently I've been working a little with MongoDB and I have to say I really like it. However it is a completely different type of database then I am used. I've noticed that it is most definitely better for certain types of data, however for heavily normalized databases it might not be the best choice. It appears to me however that it can completely take the place of just about any relational database you may have and in most cases perform better, which is mind boggling. This leads me to ask a

Mongo DB relations between objects

I'm trying to implement blog post storage using mongo db. I've got two domain entities: "Blog post" and "Author" Currently I've added AuthorId property to blog post entity. Is that the right approach to store relation between objects? Currently I've added AuthorId property to blog post entity. Is that the right approach to store relation between objects? I'd say no. You are "supposed" to store everything you need in a blog document in a denormalized way (e.g. the blog post, the comments, the tags, etc). So if you want to show the Author's name, you should add it to the blog document. This
