# Factors to consider

* What data types does it support and what are your own requirements for data types ?
* Do you need flexible schema or rigid schema ?
* Is query flexibility important to you ?
* Do you want to store large amounts of data across several machines
* How much important is sata safety (via ACID compliance or something else)
* Do you need Triggers
* Do you need Transactions (for atomicity)
* Do you need Stored Procedures
* How much important is having ability to create **Views** for you ?
* Can you live without **Joins** ?
* Do you need **Partitioning** ?
* Do you need to store only large blobs of data ?
* Do you have enough information about the database requirements (like schema, probable tables, data types etc)
