A peek into the databases
|
|
When the Paglo Crawler gathers information about your network and IT assets, it stores the data it collects in the Search Index — the repository for everything Paglo knows about your network. The Search Index is actually a dual database that holds your data in both structured and unstructured databases. Paglo's power is in how these two mix. |
Unstructured database
Paglo stores all the data that the Crawler gathers in an unstructured format that's easy to search without much technical know-how. The unstructured format includes documents that someone has written, or databases where someone has entered the data. All you do is type in any word or phrase in plain English, and Paglo instantly presents you with a hit-list with the most likely matches nearest the top.
Structured database
The counterpart to the unstructured database is the structured database — the Tree-Structured Database to be exact. It stores the same data, but in a semi-structured format that preserves the relationships between pieces of data.
For example, what good is an IP address all by itself? It's useful only if you know which interface it is assigned to, on which device, and in which network or subnet of your infrastructure. The Tree-Structured Database makes it possible to get such relationships in your hit-list. You can formulate complex queries — such as a query with IF and OR conditions — and get sophisticated answers about your network from Paglo's Tree-Structured Database.
Benefits of dual databases
Dual databases are what make it possible for you to ask complicated questions, and get sophisticated, structured answers, without using any special query language. You might wonder if a dual database system would use twice as much resources. And make things twice as complicated to use. Acutally, not at all. The cost is minimal, and the benefits are worth it. The two databases interact seamlessly. In fact, you jump back and forth between them as you search, without even knowing it — or needing to know. However, if you're curious to find out more, see straddling the dual databases.
