- 12.1: Public Chemical Databases
- Within this section, several chemical databases will be introduced which vary in size and scope. Many of these databases provide chemical information free of charge.
- 12.2: Data Organization in PubChem as a Data Aggregator
- PubChem operates a complex data aggregator that pulls information from hundreds of sources to provide a combined data hub for chemical information.
- 12.3: Database Query Introduction
- Databases must be able to provide the information needed to the users, often through searches and queries.
- 12.4: PubChem Web Interfaces for Text
- The homepage of PubChem is often where a series of searches will begin. Multiple results are displayed using the Entrez System.
- 12.5: Text Search in PubChem
- Using text to search for chemical information is a simple and fast way to find results. Different types of synonyms can also be applied.
- 12.6: Additional Data Retrieval Approaches in PubChem
- There are many ways to search PubChem without having to supply a text search. Identifiers can be used along with browsing categories.
- 12.7: Searching PubChem Using a Non-Textual Query
- Chemicals can be found in searches by using the molecular formula or the actual structure within a search.
