EO in the ADF can be seen as a Java representation of tables in a relational database.1.TypeThe type here is Java, and the type of database that needs to be mapped, there are some differences between the two, each mapping relationship is as follows:
Database column type
BC Property Type

Java.lang.String

I. background
NMP (NASA New Millennium Plan): it aims to test a series of new 21 Century satellite technologies, known as flight verification, by launching experimental satellites. It is currently included in the plan: EO, DS, and St ). The EO-1 is the first satellite to be planned for the earth, And the EO

public void Create (AttributeList attributelist)
{
Super.create (attributelist);
}
In this method you can add a field initialization statement, but it must be appended to the Super.create (attributelist).
Because the CO call am,am call Vo,vo, we need to implement the Add-record feature on the page as follows:
1. A method of creating new records in Vo.
2. The method of calling Vo in AM.
3. The method of calling AM in Co.
Because Voimpl provides a way to add records, the first step can be omit
The Uniqueness index of the Oracle database is represented in the unique index created in the database table test. The EO generated by the test table does not have specific rules corresponding to the unqiue index; when you create a unique key in the database table test, the database generates the corresponding unique index. When you use the test table to generate the EO,

A long time ago I want to order how to smoothly EO-1's Hyperion image well write a summary, helpless people too lazy. I decided to solve this problem today when I was forced to consult with many colleagues.
EO-1's geographic data acquisition system is a new type of Earth observation satellite developed to replace Landsat 7. It is also an experimental hyper
When an entity object is established in the ADF by a table that already exists in the database, it occurs:
1, the completion of the conversion of property names, for example: Java will be the database name such as manager_id property name

Topic One:Given an array of shaped arr and an integer greater than 1 K. It is known that only 1 numbers in arr appear odd times, and the other numbers appear even several times, so return the odd number of occurrences. The time complexity is O (N) and the additional space complexity is O (1).Ideas:The result of an integer n with 0 xor is n, the result of an integer n with an integer n is 0. So first apply for an orthopedic variable, which is written as EO
8-3 encoder with priority in each node
Principle:
In a digital system, several parts may send service requests at the same time, but at the same time, only one of them can send a permitted operation signal. Therefore, you must set priorities for the operation permitted by these control objects, that is, the priority level.
The encoder has 8 inputs and 3 outputs. There is also an input enable EI, output enable EO and priority encoder working status ma
management system is divided into user management sub-systems, product management sub-systems, and project management sub-systems. After the horizontal and vertical modules are divided, the entire system becomes a table-like stuff, and each cell represents a module. For the purpose of reusability design, horizontal modules cannot be referenced from each other, and vertical hierarchical modules cannot be called across layers, except for the data access layer. The architecture design in this scen
the value returned by calling the BaseEo. HasChanges method.
3. Close the current window, load the object, and delete it. In this case, the system deletes the current object from the database, and changes the state of the object to the Free State.
OK. Let's take a look at how to operate the Code:

Initialize data (data initialization ):It is mainly used to add records. There are two methods:1. Set the Default value of Page item during Design time.2. Set it programmatically during Run time.The setting of Default value is not mentioned here. It will be discussed later when "going deep into UI item.This article mainly describes how to use programming methods to set up.After EO is created, if you select to generate a JAVA file and a java class, we
