Two Dimensional and Multidimensional

Hi experts,
What is Two Dimensional and Multidimensional , i want exactly the diff between these two ? Generally we are saying that cube is Multidimensional and ODS is Two Dimensional ?
I willl asssign points for ur valuable answers .

Hi Nagireddy,
ODS is 2 dimensional format and it is not good to analyze the data in multi dimensional way.If you want to take flat reporting then go for ODS reporting. TheTwo dimensional report is similar to reporting on a table.ODS active table is a flat table like an r/3 table. Reporting is done on active table of ODS. other tables are for handling the deltas.
List of purchase orders for a vendor is two dimensional report whereas sales organisationwise, sales areawise,customerwise sales for last quarter and comparison with earlier quarters is a multi-dimensional report.
Cube is multidimensional formate and you can analyze data in different dimensions,so if your requirement is multidimensional report go for Cube.
Hope this helps,
Regards

How to get number of rows and columns in a two dimensional array ?

Hello,
What would be the simplest way to get number of rows and columns in a two dimensional array represented as integers ?
I'm looking for another solution as For...Each loop in case of large arrays.

Creating one and two Dimensional array

Hi guys my problem is as follows
(1)I want to create a two dimensional array of 10 rows and 20 columns
(2)Populate the array with random integers
(3)convert the two dimensinal array into one dimensional array int[]nums
(4)print the content of one and two dimensional arrays to the screen

You don't learn much about coding if you don't write any code. Without seeing the code that was written it's very difficult to assist a person, since your solution may not be anywhere close to their solution. If the poster just wants the code to hand in or use as is then there is no learning happening.
So, step 1 - post your code, step 1a - ask a clear question.

Creating a Two Dimensional Array in Xcode and populating it with a values f

Whats the easiest way to declare a two dimensional array in Xcode. I am reading an matrix of numbers from a text file from a website and want to take the data and place it into a 3x3 matrix.
Once I read the URL into a string, I create an NSArray and use the componentsSeparatedByString method to strip of the carriage return line feed and create each individual row. I then get the count of the number of lines in the new array to get the individual values at each row. This will give mw an array with a string of characters, not a row of three individual values. I just need to be able to take these values and create a two dimensional array.

I'm afraid you are in the wrong place. Look here for the last two forums on programming. However, XCode support is mostly found at developer.apple.com. You can access their forums by registering. Registration is free.

Create a two dimensional table in Acess

Hi,
I am working with a database and the toolkit "the database connectivity tooset". I know how to create a new table from labview, but is it possible to create a "two dimensional" table from labview, i.e, where one table in Microsoft Access is linked to another one. I know how to do it in access, but it should be possible in program to crate a new table and this one has to be linked to another one then, just like the others. Does someone know how to do it??
Thank you!

Hi
I assume you are not so familiar with databases, are you?
First I want to comment your previous post:
well I have a table for a product that contains, say different data for the product, i.e. the date of the test, who is responsible for the test, where it was performed. Also, linked to the date (I guess it is the primary key), there are also some data related. so in my table in the database, next to the date, there is a "+"-sign, so I can open up the page of all the data related to the date.
Well, did you create this database on your own? So you must have created two tables (table one with fields Datum, Responsible & Cost and table two with fields Place1, Place2, Place3 & Place4). Then you must have dragged on field from one table to another field in the other table in the "Relations" view of access. Doing so, you created a relation. Due to this, access now knows how this date is related and displays the "+"-sign. You can not assume that the date is the primary key.
In fact you do not have a "2D" table, but just different datasets from two tables connected to each other. This connection is created by relations.
So, if I know would like to create a new table in my program (each product has its own table, so a new product=a new table), I would also like to create this "data" sheet that is connected to the data. Bu how do I do that?
I can easily just create a new table (i.e. a new product), just using the "DB Tools Create Table.vi". But I guess it is when I actually want to add the data to the database, where I create the "data" sheet? Using the "DB Tools Execute Query" and a SQL statement with INSERT INTO, is that the way to go?
As mentioned before, this "datasheet" is just a dataset from a second table which is made displayable by the relation. So if you're question is "how to create a relation using LV", you are quite on the right way. First create two tables one of which has to contain a field where the primary key from the other table is linked to. Then you have to set a PK in one table (using SQL statements) and then build the relation (also using SQL statements). I can't tell you, if you have to define the foreign key in the second table too.
Have a look at the MS-Access help on how to assign relations and how to define primary keys. There may be something to take care off. Basically standard SQL should do - but using MS you never know .
As this is somehow complicated, I always create the database structure in MS Access and that's it - afterwards all is done programatically (write and read data). Usually I don't open the database again with Access unless there is a special task.
Hope this helps you a little bit otherwise come and ask again.

Need to pull the information from two facts and associated dimensions

HI All, i need to pull all the columns from the two Facts and their associated dimensions, get the results.
here is the example:
Fact1 --> D1, D2, D3
FACT2--> DA, DB, DC, D1
D1 Dimension has a Join with two fact tables, as long as i'm using columns from D1 and FACT2, DA, DB, DC report works.
but my requirement is to get the results when pulling the columns from all the dimensions and two facts like Fact1, FACT2, D1, D2, D3, DA, DB, DC
how to achieve this requirement, can someone pls help me with this.
your responses are much appreciated.
Thanks
rar

Hi RAR,
I assume you have created proper dimensional hierarchies for all the dimensions in your subject area. Also, ensure that all of them have a Total Level created.
Assuming the above, since D1 is a conformed dimension, if you create a report having columns from only D1,Fact1 and Fact2, the report should show you proper results.
For creating a report having columns from all tables, ensure the following:
1. For all measure columns from Fact1 to be included in the report, set them to be calculated at the Total Level of dimensions DA, DB and DC
2. For all measure columns from Fact2 to be included in the report, set them to be calculated at the Total Level of dimensions D2 and D3
The physical sql will fire separate queries for the 2 star schemas and then join them using the conformed dimension.
Hope this helps,
Gaurav

Variable number of two dimensional arrays into one big array

I have a variable number of two dimensional arrays.
The first dimension is variable, the second dimension is always 7.
i.e.:
Object[][] array0 = {
{"tim", "sanchez", 34, 175.5, "bla", "blub", "[email protected]"},
{"alice", "smith", 42, 160.0, "la", "bub", "[email protected]"},
Object[][] array1 = {
{"john", "sdfs", 34, 15.5, "a", "bl", "[email protected]"},
{"joe", "smith", 42, 16.0, "a", "bub", "[email protected]"},
Object[][] arrayi = ...I'm generating these arrays with a for-loop:
     for (int i = 0; i < filter.length; i++) {
          MyClass c = new MyClass(filter);
          //data = c.getData();
Where "filter" is another array which is filled with information that tells "MyClass" how to fill the arrays.
"getData()" gives back one of the i number of arrays.
Now I just need to have everything in one big two dimensional array.
i.e.:Object[][] arrayComplete = {
{"tim", "sanchez", 34, 175.5, "bla", "blub", "[email protected]"},
{"alice", "smith", 42, 160.0, "la", "bub", "[email protected]"},
{"john", "sdfs", 34, 15.5, "a", "bl", "[email protected]"},
{"joe", "smith", 42, 16.0, "a", "bub", "[email protected]"},
Any idea on how to accomplish this? It's blowing my mind right now.

Just brainstorming here:
Why not put your actual data in a class and store that in a LinkedList (so you know the total number of elements for your multi-dimensional array). Then initalize your multi-dimensional array and populate it? Haven't tested the following, but thinking something along the lines of
public class MyData {
     //data here
     public Object[] toArray() {
          //something similar to this
          return new Object[] = {"tim", "sanchez", 34, 175.5, "bla", "blub", "[email protected]"};
LinkedList<MyData> data = new LinkedList<MyData>();
data.add(mydata1);
//however many times you need
Object[][] arrayComplete = new Object[data.size()][7];
for(int i = 0; i < data.size(); i++) {
     arrayComplete[i] = data.removeFirst().toArray();
}Another option for knowing how many rows you would need might be using something like:
int rows = 0;
rows += array1.length;
rows += array2.length;
//etc...But is not entirely useful if you don't know how many variable arrays you have (although reflections might help if the name of the array variable is incremented systematically, someone told me earlier to avoid reflections since it could make debugging a LOT more difficult).

Retrieving two dimensional arrays from a text file.

Good evening
I am having a problem with reading a text file, and putting this info into a 2D array to be put into a table.
I have the table already(but no code to add rows to the table incase the array increases)
The array is called Product[a][ b ]
where a is the product number(the row), and b are details about this product.
The file i want to be read looks like this:
data.txt
CPU|AMD|X2, 64bit, 2GHz|$150|9
Video card|NVidia|7800 GTX 256MB|$400|4
e.g. product[2][4] would equal 4
Basically: Type, manufacturer, specifications, price, amount in stock.
the "splitter" or "field terminator" is "|"
This is what i want it to do:
Store fileline into single string,
split string and put it in product[ j ][ i ]
repeat with next lines until nothing is read anymore.
This is the code I have so far:
try{
        FileReader textFileReader = new FileReader("C://BACKUP2//data.txt");
        BufferedReader textReader = new BufferedReader(textFileReader);
        for(int j=0; j<0; j++){
             for(int i=0; i<6; i++){ //i starts at 0, condition: i is under 6, 1 is added to i at each loop/update.
                   ProductT = textReader.readLine();
                   textReader.close();
                   for(String Product[j] : ProductT.split("|")){ //this line is completly wrong, but i don't know how else to do it.
     // for counting for the number of columns
catch (IOException e) {System.out.println(e);}
I don't even think this code makes any bloody sense, I don't know if I'm approaching it correctly.
Would anyone be gracious enough to give me a helping hand and tell me what/how to change my code?
from what I see, the problem lies less in the loops, but more in the splitting of the string. no function seems to like 2D arrays :(

So this is where I stand:
     //Reading
    try{
        FileReader textFileReader = new FileReader("C://BACKUP2//data.txt");
        BufferedReader textReader = new BufferedReader(textFileReader);
        for(int j=0; j>0; j++){ // this will go on forever now or what?
// yes, this will loop forever, which is fine as long as you break out of the loop when you reach the end of the file (which is indicated by textReader.readLine() returning null)
             // replace the for(String currentField : ProductT.split("|")) loop with this one
             //for(int i=0; i<6; i++){ //i starts at 0, condition: i is under 6, 1 is added to i at update.
                  String inputline = textReader.readLine();    // read a single line from the file each time through the loop
                  //while (inputline != null) {
                        if (inputline != null) {    // check if the end of the file has been reached
                       //ProductT = textReader.readLine(); //put to single string
                   //textReader.close(); //shut it off    // move this line to the end of processing, you don't want to close the file until you've read everything from it.
                   //for(String currentField : ProductT.split("|")){   //Split string...      according to JBuilder "The local variable currentField is never read"
                         // switch this loop to use the regular for( ; ; ) type, that way you will have another counter to use as the second index in the product assignment
                                     //currentField = Product[j];
                    product[i][] = currentField; // use the index of the second loop as the second index here
else {
break; // break out of the loop when end of file is reached
     //} // the for i etc. end here
} // End for j et cetera...
     } //end Try
catch (IOException e) {System.out.println(e);}
//cut the crap
// close the reader here
ok - so I am not quite sure about what you mean here
"Assign each of the 5 fields to the five [][j]
positions of the array. "
should i put 5 "fors" in there? - currently the
program is compiling - although they do not appear in
the table.I put comments in the code that should answer those questions.
The code for the table is
Object[][] data = {
          {Product[0][0], Product[0][1],
               Product[0][2], Product[0][3], Product[0][4]},
               {Product[1][0], Product[1][1],
Product[1][2], Product[1][3],
uct[1][3], Product[1][4]},
                      {Product[2][0], Product[2][1],
Product[2][2], Product[2][3],
ct[2][3], Product[2][4]},
                          {Product[3][0], Product[3][1],
Product[3][2],
Product[3][2], Product[3][3], Product[3][4]},
                {Product[4][0], Product[4][1],
Product[4][2],
Product[4][2], Product[4][3], Product[4][4]},
;If I do not declare any of these strings (e.g. I have
only declared Product[0-2][] oldschol style) an error
occurs, telling me that
Caused by:
java.lang.ArrayIndexOutOfBoundsException: 3
     at data.<init>(data.java:112)
     ... 5 more
When you declare product, you'll need to give it a size for both dimensions. The first dimension will be the number of lines to be read from the file. You'll need to know this before allocating the array, so either count them in the file, (if that's good enough for this assignment) or loop through the file once before reading it to count the lines. The second dimension of the array will be 5, since that's how many fields each line has.
btw; do I give those duke stars when all problems of
my life(currently: reading the two dimensional
string) have been resolved?I don't know about [i]all the problems of your life, but when the topic of the thread has been solved, then give them to whoever helped. :)

Two dimensional Grouping

Hi 2 all,
I'm trying to build a report starting from two complex PL/SQL query like this(simplified):
SELECT SUM(x),SUM(y),SUM(z),Name,type,product
FROM DESC A, STORE1 B, STORE2 C, store3 D, store4 E
WHERE b.ID=c.ID(+)
AND b.ID=d.ID(+)
AND b.ID=e.ID(+)
AND a.code=b.code
AND a.product='oneproduct'(...another query with !='oneproduct')
group by b.Name,b.type
I need to have on each report page the results of the two queries grouped by type, one page for each (Name).
how can I have the content of Name field on the header/margin (as a title) and the remainder data below grouped by the same Name?
=> In the end I should have one page for each Name
thanks
Matteo

On the other hand I do recall having read somewhere
that the "new" operator
is very costly and should strictly be
avoided in loops.Not that expensive performance-wise. It could potentially suck up a lot of memory if you are creating LOTS of objects
Now for the concrete case of reading some user's
datasets from a database
and then processing them further, is it advisable
to instantiate a new user object for each row, or
where is the alternative
to be found?I think you should create an object to represent each row.
two dimensional collections (any favourites in java)I always create my own. I try to use Vectors and Hashtables exclusively, depending on my needs re: ordering and lookup. Mixing and matching these could result in Vectors of Hashtables, Vectors of Vectors, Hashtables of Vectors, and Hashtables of Hashtables.
synchronized one dimensional collections each
representing one field in a
table ? (is this really more performant than simple
classes)Doubtful - any gain that you get by avoiding the constructor call would be obviated by the overhead of iterating through multiple lists and keeping them synchronized.
a Collection of Collections (here comes the new
operator again)Same as two-dimensional collections.
I remember having seen inner classes used for the
purpose of holding just a
couple of attributes, is there some performance
advantage like "the class
loader does not have to look for the class".No advantage - the only reason to create an inner class is to prevent other classes from using those objects. The inner class still compiles to a separate class object that needs to be loaded separately.

Formatting a two-dimensional list...

Is there a way to create a two-dimensional ArrayList of Integers with all cells containing certain values, for example zeros? -I will be storing changing Integer values in certain x- and y-coordinates!!
Something like:
ArrayList<ArrayList<Integer>> list = new ArrayList<ArrayList<Integer>>();But my problem is that the .get commands cause an Exception if a cell value is not set:
list.get(x).get(y) and list.get(x).set(y,int)How could I get around the "null" values without Exceptions? Would you first replace the null values with zeros? (Or is there some other way to store such information?)

If you want to a fill a List up with values, use java.util.Collections.fill().
But do you really want it full of some kind of value, or do you just want to indicate "no value filled in" for a bunch of positions in the grid? What percentage of positions will not be filled in, or will be filled in with the default?
Here's a simple sparse grid:
public class Pair {
final int x;
final int y;
public boolean equals(Object o) {
    Pair p = (Pair) o;
    return p.x == x && p.y == y;
public int hashcode() {
    return x + y;
public class SparseGrid {
private Map<Pair, Integer> grid = new HashMap<Pair, Integer>();
public Integer get(Pair p) {
    Integer i = grid.get(p);
    if (i == null)
      return 42; // the default. or just skip this test if you don't want a default
    return i;
// also a put method, left as exercise
}That's all untested.

Problem returning a two-dimensional array in web service

Hello. I'm having problems returning a two dimensional array in my web service. The service returns a MyClass[][] correctly, but the client receives a different one.
I've done a test that returns a MyClass[1][1] an the client shows a MyClass[1][20]. All the MyClass objects returned in the array are the same and all it's fields are null. There's even an element of the array containing null instead of the object. As I say, the service creates the array ok, but the client gets other thing.
I have other methods returning one-dimensional arrays MyClass[] and I have no problem.
My system:
WindowsXP
Tomcat 5.5 (Axis 1.3?)
JDK 1.5
Eclipse 3.3
My wsdl is generated with eclipse, although I've had to update my wsdd manually.
Any Ideas?
Thanks.

Does it have to be stored in an array?
Because you could use the java.awt.Point class, and a
java.util.Set to create random points until you have
the correct number of unique points.Of course it is no must to store it in an array. it was just my first thought of approaching the problem. I will try the Point.class. Thanks for that hint.

Mapping question - one dimensional to two dimensional

Hi
   We are on XI 3.0 SP13 - and I have this mapping scenario
Source structure - Linear & simple with say 10-20 fields -
Target structure - Name -value field pair with an unbounded node on top -
                            <b>MsgAttrib 0-Unbounded
                                Name
                                Value</b>
I have to map each distinct field value from the source structure - to the Value field on target structure. The Name field in the target structure should contain the name of the source field ( it can contain a constant - field name if we cannot get the source element name during mapping runtime, thats ok )
So basically each elementname and its value on the source structure form a record on the target xml. The next source element and its value will be mapped to the next record on the target xml - this filling up the two dimensional target structure - with as many rows as the number of source fields to be mapped. The number of such source fields to be mapped can grow . ( there should not be any limitation on that )
Can this be accomplished using standard functions in message mapping - or should we resort to writing udfs ?
Any right thoughts, solutions to solve this mapping scenario will be awarded points rightaway .....

Hi karthik,
The mapping that ur scenario requires can be accomplished using the standard functions...
now ur source structure is unbounded...tht means it can have multiple occurences...
and for each occurence you have a pair of values in target message under a node....
now the important thing here is ..tht ur target node which has those two fields under it will repeat as many times as occurences of the source message...
so u need to map the main message type node of the source to this node in target...
and according map the fields under tht node...
UDF's are not required for this....

How to create an Object array(two dimensional) from a properties file..

Hi All..
I have a typical problem..
I have a properties file with key/value pairs . Now what I want to do is.. I need to read all the keys and the values corresponding to that keys and then create a two dimensional array.. Like..
Properties props;
Object[][] contents;
My contents should be like
contents = {{key1,value1},{key2,value2},{key3,value3},...};
Can someone tell me how to do this.. asap...
TIA

Just because something is difficult for you does not qualify it as an "Advance Language Topic"... And it certainly doesn't allow you to multi-post.
