The Ultimate API to your SQL database

Site is being refactored.
Please revisit soon.
Uses your current SQL database
SchemaFreeSQL's powerful API allows easy storage & import of Object-Oriented/Hierarchical data into YOUR database.

Continue to access your database through your existing DB Connector as you normally would.
Access your Database through the SchemaFreeSQL API when needed.

Any existing tables co-exist alongside SchemaFreeSQL's automatically-created tables in the tablespace of your choosing.

MySQL is currently supported. Other DB support is on the roadmap including PostreSQL, Microsoft SQL Server, SQLite, Oracle, and cloud offerings.
Easily Store Complex Data
  • No Tables to create
  • No Indexes to create
  • No data duplication
    • Multiple references to the same object (e.g. Employee) are only stored once, as a single object
    • That single object can be graphed into the data structure as a lightweight reference from other locations (e.g. MasterList->Gamer, Team->Gamer, Event->Gamer, etc) without having to create and manage foreign keys and indexes.

Example of the kind of deep, hierarchically structured data that SchemaFreeSQL can store and query. (source: Pubmed)
Query like this...
SELECT $s:Author.LastName as lastname, $s:Author.ForeName as forename ORDER BY lastname,forename LIMIT 5
...and get this
(style: ) 
{
  "data" : [
    {
      "forename" : "Jacobus",
      "lastname" : "Albertyn"
    },
