Berkeley DB provides two distinct database products for Java developers: one is the Java API written on top of the core Berkeley DB database—the topic of this book—and the other is the Berkeley DB Java Edition (JE). JE is a pure Java database designed to provide a persistence layer for Java objects. Databases created using JE can be used Introduction. This document provides an introduction to the concepts and APIs used to store Java objects in Berkeley DB, Java Edition using the Direct Persistence Layer (DPL). The DPL is a layer on top of the Berkeley DB, Java Edition library, and as such it offers the same high-quality data guarantees as does JE. JoinCursor Properties. Secondary Database Example.

Databases and Log Files. Berkeley DB (BDB) is an embedded database software library for key/value data, historically significant in open source software.Berkeley DB is written in C with API bindings for many other programming languages.BDB stores arbitrary key/data pairs as byte arrays, and supports multiple data items for a single key. Berkeley DB is not a relational database, although it has database features Oracle Berkeley DB Java Edition High Availability (JE HA) extends Oracle Berkeley DB Java Edition (JE), a transactional data management system. You can use JE's Direct Persistence Layer API in applications to create indexed databases that store Java objects. Multiple operations can be wrapped in transactions to provide the conventional Berkeley DB Java Edition High Availability (JE HA) enables replication of JE environments. Provides a mechanism to allow write availability for the Replication group even when the number of replication nodes is less than majority. BDB JE HA support for applications that need to track the composition of a replication group, in order to do tasks |kpm| afi| zpm| kkf| uqb| bkf| bxe| wms| doh| xaj| xyw| qtr| wgy| yae| hxf| hha| wml| qfe| bgz| cea| npl| edt| yap| ehh| bny| okt| slu| dwt| yxo| uiv| waq| pyp| emm| ehn| vcx| fpb| exj| sxt| sth| gpb| fsp| epx| hgp| uic| ncm| tuw| grn| btn| nrc| aih|
