XML Datastores

XML is a powerful technology for exchanging data between disparate systems and VistaDB provides full support for importing and exporting to XML. However, XML cannot replace or match the benefits of using a relational database engine for managing data. XML is a meta language designed for describing the contents of documents, thereby giving some structure to free flowing documents. XML is ideal for storing small amounts of data easily and effectively, and of course, XML is fantastic for exchanging data between disparate systems (i.e. importing or exporting).

While it is true that data can be stored to a flexible XML document, XML is only a partial data storage technically since it lacks a built-in mechanism to index, retrieve, filter, encrypt, compress and lock the data. XML by itself lacks any form of transaction processing and offers no support for concurrent read/write access by multiple users.

XML not up to database applications
XML is simply not a viable replacement for a robust and feature-rich serverless database engine such as VistaDB. The cost of adding any of the features listed above (searching, indexing, security, locking etc.) would far exceed the cost of purchasing VistaDB.

For desktop database solutions XML may solve a short term need to persist data, but it is not a desktop database API and cannot store relations between data.

We have many customers who have told us they originally just came to VistaDB as a datastore to replace XML and allow built in encryption and compression for shipping data across machine boundries. After they began to use VistaDB they saw the power of having a zero config database engine on the client desktop and developed much more powerful solutions as a result.
