An object relational-mapping (ORM) library for Java
The Hibernate projects offer a suite of powerful Java libraries to work with data. It is best known for Hibernate ORM, which provides relational persistence for Java models and is an implementation of the Jakarta Persistence specification.
Hibernate projects do not consistently release binaries or documentation to SourceForge anymore. For up-to-date information, refer to the Hibernate website:
* Hibernate ORM: https://hibernate.org/orm/
* Hibernate Validator: https://hibernate.org/validator/
* Hibernate Search: https://hibernate.org/search/
That website will also be updated with newer projects, such as Hibernate Reactive.
xUtils includes orm, http(s), image, view annotations, but it is still very lightweight (251K), and has powerful features and is easy to expand. Efficient and stable orm tool, which makes it more convenient to support cookies and caching when the http interface is implemented. Based on UrlConnection, the bottom layer will be implemented by okHttp after Android4.4. The request protocol supports 11 predicates: GET, POST, PUT, PATCH, HEAD, MOVE, COPY, DELETE, OPTIONS, TRACE, CONNECT. Supports uploading of very large files (over 2G). Support breakpoint download (if the server supports the Range parameter, the client automatically handles the breakpoint download). Support cookies (implements domain, path, expiry and other features). Support caching (implement Cache-Control, Last-Modified, ETag and other features, use expiration time + LRU dual mechanism to clean up when the cache content is too much).

A low-code dashboard makes monitoring intuitive for any admin, while scripting and custom sensors give experts full control.
You shouldn't have to choose between a monitoring tool that's easy to use and one that's powerful enough for a complex environment. PRTG's low-code interface lets any admin build dashboards, set alerts and monitor devices without scripting, while custom sensors and full API access are there when your team needs deeper control. One platform, no compromise. Download a free 30-day trial now.
Simple (Easy) Object Relational Mapping for Java
Sormula is a Java library that moves data between Java objects and relational database tables.
* Easy to Use
* Simple to Understand
* Minimal Configuration
* Portable
It provides select, insert, update, and delete, and many other common operations. One-to-one and one-to-many cascading for unlimited levels. Simplified IN operator parameter as java.util.Collection. Custom conversions between any Java class/type and column type.
* Works with any relational database. Tested with H2, HSQLDB, Derby, SQLiteJDBC, MySQL, MariaDB, Firebird, DB2, Oracle 11g, PostgreSQL.
* Performs as fast as plain JDBC. Performs faster than plain JDBC when caching is enabled.
* Zero-configuration, zero-annotation use is possible.
* Active record pattern may be used but is not required.

Cassandra "ORM" with hooks for Jersey integration if desired
Using the new CQL3 driver by Datastax Artemis provides extremely easy to use "ORM" like functionality for Cassandra. It also contains hooks for integration into Jersey2 to enable rapid development of RESTful services, or even websites, if you enable JSP functionality for Jersey. If there is a demand, I could add a plugin to render views using things like Velocity, etc.

AutoDAO is a Generic DAO on steroids implementation for Java with Hibernate support, annotation-driven configuration, tight Spring Framework integration and zero persistence code required for most common query types.
ABL is a transaction logic engine: it allows you to declare complex, multi-table transaction logic for your persistent objects, using simple declarative annotations.
ABL operates as a HIbernate/JPA event listener to eliminate recoding and automate integrity.
Cane is a Data Manipulation Interface(DMI) based on code behaviour analysis. Cane enable developers manipulate data in the way close to natural logical. Developers can finish their job in one continuous operation supplied by Cane's chain operation
A powerful 100% JAVA flat file processing ORM framework. Giving the ability to abstract the processing of flat files from business logic, using Hibernate style mapping constructs. Supports fixed length and delimited (e.g CSV) file formats.
Criteria2JPQL API is an adaptation of the powerful Hibernate Criteria API to standard JPA API enabling the compatibility with any orm tool. Against the native SQL queries created by Hibernate Criteria, Criteria2JPQL outputs standard JPQL queries.
This is android library to simplify Android SQlite Database
It become very tedious to write large Android SQLite Open helper for simple database usage. So I developed this library to create android databases very easily using straight forward functions.

Makes relational data easy and fast to use with semantic annotations and encapsulated datatypes.
Simple declaration of a DB table:
@DBTableName("mytable")
public class MyTable extends DBRow {
@DBColumn("numeric_code")
@DBForeignKey(Code.class)
private DBNumber numericCode = new DBNumber();
@DBColumn("uid_mytable")
@DBPrimaryKey
@DBAutoIncrement
private DBNumber uidMyTable = new DBNumber();
}
Easy Gets:
List<MyTable> myRows = myDB.get(new MyTable());
MyTable row = myDB.getDBTable(new MyTable()).getByPrimaryKey(61176904);
Natural and Outer Joins and Criteria:
CarCo carCo = new CarCo();
carCo.name.isLiterally("GM");
List<DBQueryRow> results = myDB.get(carCo, new Marque());
dbQuery.addOptional(new CarModel());
Easy debugging:
query.getSQLForQuery();
Simple processing:
db.print(query.getAllRows());
List<Marque> marques = query.getAll
This java component will help you to convert JPA entities to DTO/View classes and vise versa.
Can be very helpfull when developing GWT backend services or backend services for Flex apps, or REST services.
A lightweight framework to create and process metadata based, type-safe, debugable, readable, and maintainable queries for JPA 2.0. Example: CriteriaComposer(Student.class).select(AggregateFunction.SUM, Student_.unit).groupBy(Student_.name);
Ebean provides multiple levels of query abstraction ORM Queries, mixed with SQL, DTO Queries, SqlQuery and JDBC. Work at the highest level of abstraction and drop down levels as needed. Built in DB migration generation and running. Support for "rebase" migrations as well as repeatable, init and 'normal' migrations. Ebean produces SQL that you would hand craft yourself. Use great SQL, never generate SQL cartesian product, always honor relational limit/offset. For ORM queries Ebean can profile the object graph being used and either automatically tune the query. Docker test containers for all the supported databases. Get 100% test coverage on all the features of the database we use. We can build queries using type safe query beans. IDE auto-complete when writing queries, compile time checking and it's FUN. Optimize queries to only fetch what we need (partial objects). Automatically avoid N+1 via a smart load context.
