SchemaSpy analyzes database metadata to reverse engineer dynamic Entity Relationship (ER) diagrams. It works with just about any JDBC-compliant database (Oracle/MySQL/DB2/SQL Server/PostgreSQL/Sybase/etc) and can identify Ruby on Rails relationships.
...Once Objectwiz is installed (one jar and two xhtml files) in the application, administrator can perform the following operations:
- display all objects of a particular entity bean,
- create/edit entity beans objects,
- call methods from the session beans,
- launch EJBQL query
The Open Extract Processor (OEP) is a database ETL utility capable of merging/sorting/aggregating large partitioned database extracts. Native data files can be created from text files or from the accompanying MYSQL and Oracle import/export programs.
Deploy in 115+ regions with the modern database for every enterprise.
MongoDB Atlas gives you the freedom to build and run modern applications anywhere—across AWS, Azure, and Google Cloud. With global availability in over 115 regions, Atlas lets you deploy close to your users, meet compliance needs, and scale with confidence across any geography.
Abstract model for serialization of entities that may be listed, this includes all representations to be made in database managers that use the entity relation model. Currently only compatible with MySQL using PSF.DAPI based on MySQL NET connector
aSVERD is a little system for generating Entity Relationship Diagrams (ERD) as Scalable Vector Graphics (SVG). SVG can be viewed and zoomed in a Web Browser. The diagrams can be edited with an SVG editor and round-trip updated against the database.
This framework allows the definition of attributes, entities and relations as used in entity-relationship (ER) models. It will then handle input and representation of data appropriately.
A graphical data modeling tool, allowing one to build Entity-Relation data models for use with Relational Databases (RDBMS). The tool allows one to forward generate a SQL script of statements to build the model within a SQL92-compliant database.
Stop Cyber Threats with VM-Series Next-Gen Firewall on Azure
Native application identity and user-based security for your Azure cloud
Gain integrated visibility across all traffic in a single pass. Deploy Palo Alto Networks VM-Series to determine application identity and content while automating security policy updates via rich APIs.
Generate Entity Relationship Diagrams for a a database supported by the ADODB library, using PHP. The data for this ERD is kept in a table in the database.
Entity-relation (ERW) database modeling tool for both windows and *nix/*nux. PyDBDesigner intends to be similar to Power Designer or Erwin. Both physical and logical models are supported. Main features are database modeling, SQL generation, documentation
Yet Another Database Designer - the goal of the project is to develop
a tool for designing relational databases. YAD_Designer is based on the entity
relationship model (see Chen et al.) and is targeted on the use in educational environments.
AutoSQL provides a simple and easy to use framework meant to be a substitute for J2EE Entity beans and JDO. AutoSQL data objects give just the right abstraction from a writing SQL without being too far removed from the power of SQL.
A unique persistence layer for Java. CODO (Cursor Oriented Data Objects) maps generated Entity interfaces (suitable for DTOs) to a relational database via rendered SQL, reflection and JDBC Cursors where possible - avoiding associations.
J2EE based database access; an alternative to Entity EJBs that allows for much higher performance, easier use, less coding, more dynamic, and more tuned to use with a web presentation layer (such as Tapestry).
