Unstructured data is one of the biggest contributors to the data explosion. Defined as just about any kind of data that lacks a strict data model -- essentially, any data that isn't in a database of some kind -- unstructured data includes log files, documents, audio files, and images. This kind of data is difficult to manage due to the wide range of formats and lack of standardized metadata attached to them.
Here are some quick tips that will help you monitor and control how this data is created and stored in your environment.
Put someone in charge
Methods used to manage this data usually involve one of two different strategies: Either draw the data into a database where it can be easily mined, archived, and eventually discarded, or try to apply an organizational structure to the way that mixed data is stored. The former is often used with data that has a somewhat consistent format, such as log files. The latter is often the only avenue open to generalized file-sharing data short of a comprehensive document management system.
