database - Googling DAL & DAO returns only C# .NET related results – Does a DAL/DAO type pattern exist in Java? -

-

the subject line says all. googling dal & dao returns c# .net related results.
there dal/dao equivalent pattern in java world? there reference implementations available?

of course applies java well: don't repeat dao!

have @ fowler's patterns of enterprise application architecture. core j2ee patterns refers dao.

it'd interesting check dates on c#/.net references. i'd bet idea started on java side , adopted later .net. microsoft had persistence technology "best practice". if recall correctly, vb used tie ui elements closely columns, without intermediate layer in-between separate view database.

php - PHPDoc: @return void necessary? -

is necessary this: /** * ... * * @return void */ i have quite few methods don't have return value, , seems redundant put in comment. considered bad form leave out? if makes clear documentation, leave in, isn't strictly necessary. it's entirely subjective decision. personally, leave out. edit stand corrected. after little googling, wikipedia page says: @return [type description] tag should not used constructors or methods defined void return type. the phpdoc.org website says: @return datatype description @return datatype1|datatype2 description the @return tag used document return value of functions or methods. @returns alias @return support tag formats of other automatic documentors the datatype should valid php type (int, string, bool, etc), class name type of object returned, or "mixed". if want explicitly show multiple possible return types, list them pipe-delimited without spaces (e.g. "@retur...

this question has answer here: how convert between big-endian , little-endian values in c++? 28 answers i've been looking around how convert big-endian little-endians. didn't find solve problem. seem there's many way can conversion. anyway following code works ok in big-endian system. how should write conversion function work on little-endian system well? this homework, since systems @ school running big-endian system. it's got curious , wanted make work on home computer also #include <iostream> #include <fstream> using namespace std; int main() { ifstream file; file.open("file.bin", ios::in | ios::binary); if(!file) cerr << "not able read" << endl; else { cout << "opened" << endl; int i_var; double d_var; while(!file.eof()) {...
