A NoSQL Schema Evolution Language

Many NoSQL data stores have the advantage of being schema-free (although the data still has an implicit structure).  However, NoSQL stores don't have convenient schema management tools for when the schema evolves with the application.  This recent paper [pdf] declares and outlines a NoSQL schema evolution language for use in the admin console.

Using our evolution language, developers can specify common operations, such as adding, deleting, or re-naming properties in batch. Moreover, properties can be moved or copied, since data duplication and denormalization are fundamental in NoSQL data stores. We emphasize that we do not mean to enforce a relational schema onto NoSQL data stores. Rather, we want to ease the pain of schema evolution for application developers.

 -- Stefanie Scherzinger, Meike Klettke, Uta Storl 


The authors of the paper also say that that this language can be implemented by a large class of NoSQL databases.

 Well, I am web-developer, but I am using mysql, I'm working a website about jobs . I have problem with big databases, because my website gets the contents for different websites and then I have slow speed sometimes when I have many users and a big database because it is a
queue because mysql executes every command by order in the same database.

I heard the solution is a NoSQL, it has any queue because it has files which can access many times.

My problem I don't understand NoSQL philosophy. Can I use the typical sentences for sql "select * ...."? . Should I study NoSQL in different way? Can I use this a cluster?

I know they are many NoSQL databases. What do you recomend?

Sorry for my English.

I hope you can understand to me.
