oracle er diagram tool

exporting ER diagrams to Erwin format, only import is supported. This requires our second approach. Another approach is to use the Orthogonaltoolbox gadget, which is a small tool that is specifically responsible for visioer, which generates the corresponding sqlscript through an XSLT template. How to use: 1. Download and install the Orthogonaltoolbox (Note: the. Net Framework 1.1.4322,http://download.csd

In the painting ER diagram when looking for a more useful and professional point of the tool, looking for a half-day finally chose the seemingly less professional EA to draw ER diagram Briefly explain how the EA is implemented to draw

the box. For the primary property name, underline it under its name. Connections: Between entities and attributes, between entities and relationships, between contacts and attributes, and by a straight line, and by marking the type of contact on a line. (For one-to-many connections, write 1 on the two-entity connection direction; On one side write 1, many of the parties write n; for many-to-many relationships, write n,m in the direction of two entity lines. ) First , we want to use the shape o

directionality, and there is a cardinality in each direction.ExampleThe link between "department" and "student" two entities is a one-to-many connection, in other words the link between "student" and "department" is a multi-pair connection. And a student must belong to a department, and can only belong to a department, can not belong to 0 departments, so from the "student" entity to "department" the base of the entity is "a", from the other side of the contact to consider, a department can have

the direction of the link, generally with a verb or a dynamic table.For example, the "Students to subject" group box should be filled in with "owning", and "belong" in the "Lessons to student" group box. (Here is just an example, maybe some words are not very reasonable).Vii. Mandatory definition of linkagesMandatory the mandatory relationship between the form and this direction. Select this check box to create a vertical line of contact lines on the contact line. Not selecting this check box i

After the database management software files and DBMS files are installed, a database that installs the ORCL name of the default first instance database is created automatically. Once the instance database has been created, the default is to lock all accounts out of the system (except SYS and the SYSTEM account is available), Suggest password management on the right, and unlock the common Scott account and enter the password.

The best way to master and use a tool is to master its principles first, understand its architecture, and then use it handy, or else use it, and don't know why this step does this, not to quickly locate the problem, let alone solve the problem quickly.Ogg Architecture and principles:the principle of Oracle GoldenGate is quite simple, that is, by extracting the source-side redo log or archive log, and then t
