| | java.net: Berkeley DB, Java Edition I: The Basics |
| | Berkeley DB does allow multiple applications to open the files associated to a database, but only one process is allowed to write to the database (and the other processes, because they are caching data, might not see recent changes). | | | A Berkeley DB database is a map from keys (which are indexed) to values. | | | The original version of Berkeley DB is written in C. This means that, up until now, if a Java programmer wanted to use Berkeley DB, she would have to use some sort of translation layer (for example, JNI) to handle the communication between Java and Berkeley DB. |

| | Berkeley DB is the open-source embedded database system intended for use by software developers. | | | Berkeley DB is able to store single keys and values as large as 2**32 bytes, or four gigabytes, in size. | | | Because Berkeley DB can be deployed in so many different ways, Sleepycat has provided the tools developers require without mandating their use; for example, Berkeley DB's support for multi-threaded operation. |

| | Berkeley DB adds XML smarts InfoWorld Review 2004-04-09 By Rick Grehan |
| | Berkeley DB XML queries use the XPath 1.0 XML query language standard. | | | Luckily, the Berkeley DB XML documentation suggests an iterative query tactic to avoid this: Program the first query to return a set of matching documents, then iterate through that set, re-issuing the query on individual documents, and examine the returned elements. | | | You can accelerate queries by defining indexes, and Berkeley DB XML has a flexible indexing scheme that lets you create indexes for elements (or “edges”, which are paths to elements, rather than the elements themselves) and define the index structure so that it’s optimal for the expected queries. |

| | Enterprise IT Planet Product Guide - Berkeley DB (Sleepycat Software Inc) |
| | Primary differences between the Berkeley DB and the Berkeley DB Java Edition are their base architecture; with the Berkeley DB in ANSI C and the Java Edition written in pure Java. | | | The vendor notes that the libraries are tightly integrated within their native environments, leading to some technical and structural differences as well; for example, Berkeley DB uses page based locking whereas the Java Edition stores all data and transaction information within a single set of log files and utilizes record level locking. | | | Developers can use the software freely within their projects provided their projects themselves are also distributed as open source; to use the DB in a non open-source application will require a license from the vendor. |
