Is SOLID Outdated?

What are more modern definitions/terms for design principles for OOP?

Thanks

Does anyone know of good software design application? Something I could use to visualize the logic of my php scripts before coding?

Explain Big O notation, Binary Search and Logarithms, C#

I am curious to learn more about Big O, Binary Search and huge data sets.

What sorting and searching methods maximize performance for millions of records?

Is Binary Search still used here?

Thanks

Need to implement Spring Security for a project.

Option1:

  Structure: User table, Permission table, Module table and PermissionGroup table
  User will have only one permission group.
  Permission table will have read/write/update etc.,
  Module will be product/sales/order
  Permission group table will be product - read/write, sales - read/write/update

Option2:

 Structure: User table, Roles table, Permission table,
 User can have 1 role
 Permission table will have as product_read, product_write, sales_read, sales_write

Comments on Option2:

 We can able to use Spring hasRole() kind of configuration for each method and can associate a role to it.
 Drawback: We cannot have dynamic roles as we can able to do it option1

Comments on Option1:

We can have dynamic groups however we cannot use spring hasRole(). Instead we need to get the manual decisions based on the http request - PUT/GET/POST and check for the permissions configured and decide whether to allow the URL or not in the interceptor.

Drawback:

This may not be a standard practice
What would be the best approach out of this two as well as preferable one?

Thanks.

import org.json.simple.JSONObject;

class JsonEncodeDemo {

   public static void main(String[] args){
      JSONObject obj = new JSONObject();

      obj.put("name", "foo");
      obj.put("num", new Integer(100));
      obj.put("balance", new Double(1000.21));
      obj.put("is_vip", new Boolean(true));

      System.out.print(obj);
   }
}
On compiling and executing the above program the following result will be generated −

{"balance": 1000.21, "num":100, "is_vip":true, "name":"foo"}

Select all Open in new window

what above example doing
is it encoding jsonobject to java object?
i see output also seems like json to me?

Following is another example that shows a JSON object streaming using Java JSONObject −

import org.json.simple.JSONObject;

class JsonEncodeDemo {

   public static void main(String[] args){
	
      JSONObject obj = new JSONObject();

      obj.put("name","foo");
      obj.put("num",new Integer(100));
      obj.put("balance",new Double(1000.21));
      obj.put("is_vip",new Boolean(true));

      StringWriter out = new StringWriter();
      obj.writeJSONString(out);
      
      String jsonText = out.toString();
      System.out.print(jsonText);
   }
}
On compiling and executing the above program, the following result is generated −

{"balance": 1000.21, "num":100, "is_vip":true, "name":"foo"}

Select all Open in new window

how above one is differen from first one?

See this code:

$piece1 = $test;
$piece2 = "";
$piece3 = "";
$ln = strlen($test);
if ($ln > 84) {

	$arrayWords = explode(' ', $test);

// Max size of each line
	$maxLineLength = 84;

// Auxiliar counters, foreach will use them
	$currentLength = 0;
	$index = 0;

	foreach ($arrayWords as $word) {
    // +1 because the word will receive back the space in the end that it loses in explode()
		$wordLength = strlen($word) + 1;

		if (($currentLength + $wordLength) <= $maxLineLength) {
			$arrayOutput[$index] .= $word . ' ';

			$currentLength += $wordLength;
		} else {
			$index += 1;

			$currentLength = $wordLength;

			$arrayOutput[$index] = $word . ' ';
		}
	}
	$piece1 = $arrayOutput[0];
	$piece2 = $arrayOutput[1];
	$piece3 = $arrayOutput[2];
}	

Select all Open in new window

This works perfectly, except I need a variation where I can limit the FIRST line ($arrayOutput[0]) to 84 & the subsequent lines to 94. See attached image for visual of this need. The text is printed using a pdf generator on an existing form image (with the word Remarks & the lines.)

How can I do this?

Thank you

Hello,

I am looking to create a web-based application that, at a later date, may have a supporting windows program and mobile app (but not for phase 1).

I was considering the language to write the code in and which one would be best and was looking for your advice. These were the high-level requirements.

Will utilize a back-end database.
Will need to create PDFs based on templates and information held in the database (i.e. like an order receipt).
Will need to create PowerPoint, Word and Excel documents based on templates and information held in the database (i.e. create a copy of the order in PowerPoint format).
Allow the user to view information in tables that can be edited directly in the table with a double click or similar.
Ability for the system to generate and send emails
The ability for the system to generate an email in Outlook and save in the user's draft folder.

It would be great to get your thoughts on this given the high-level requirements.
