Could u send me the document more detail about DAO in Petstore
I have error when I customize Petstore:
I replace searchItems function with searchFullDocument But I have error as follows:

Questions about DAO pattern

Hi,
I am a junior programmer and I am trying to understand somewhat more about best practices and design patterns.
I am looking for more information regarding the DAO pattern, not the easy examples you find everywhere on the internet, but actual implementations of real world examples.
Questions:
1) Does a DAO always map with a single table in the database?
2) Does a DAO contain any validation logic or is all validation logic contained in the Business Object?
3) In a database I have 2 tables: Person and Address. As far as I understand the DAO pattern, I now create a PersonDAO and an AddressDAO who will perform the CRUD operations for the Person and Address objects. PersonDAO only has access to the Person table and AddressDAO only has access to the Address table. This seems correct to me, but what if I must be able to look up all persons who live in the same city? What if I also want to look up persons via their telephone numbers? I could add a findPersonByCity and findPersonByTelephoneNumber method to the PersonDAO, but that would result in the PersonDAO also accessing the Address table in the database (even though there already is an AddressDAO). Is that permitted? And why?
I hope someone can help me out.
Thanks for your time!
Jeroen

That is exactly what I am trying to do. I am writing it all myself to get a better understanding of it.
Please bear with me, because there are some things I dont understand in your previous answer.
1) Each BO validates his corresponding DTO and exposes operations to persist that DTO. Each DTO will be persisted in the database via his corresponding DAO. So this would be:
- in PersonBO
public void save(PersonDTO personDTO) {
this.validate(personDTO); // does not validate the nested address DTOs
this.personDAO.save(personDTO); // does not save the nested address DTOs
- in AddressBO
public void save(AddressDTO addressDTO) {
this.validate(addressDTO);
this.addressDAO.save(addressDTO);
Am I viewing it from the right side now?
2) Imagine a form designed to insert a new person in the database, it contains all fields for the Person DTO and 2 Address DTOs.
How would I do this using my Business Objects?
This is how I see it:
// fill the DTOs
daoManager.beginTransaction();
try {
personBO.setDao(daoManager.getDao(PersonDAO.class));
personBO.save(personDTO); // save 1
addressBO.setDao(daoManager.getDao(AddressDAO.class));
addressBO.save(personDTO.getAddress(1)); // save 2
addressBO.save(personDTO.getAddress(2)); // save 3
daoManager.commit();
catch(Exception e) {
daoManager.rollBack();
If I insert the transaction management inside the DAOs, I can never rollback save 1 when save 2 or save 3 fail.
It can be that I am viewing it all wrong, please correct me if that is the case.
Thanks!
Jeroen

Is dao pattern is the best practice in projects

let me know if dao pattern is the best followed in all almost all the
projects though finding alternatives to it. please clarify this for me and also i do want to know the best practices of the industry in using design patterns.

There is no 'best' pattern. It is just all abouthow
and where to apply them. This is very true,but these are common
design patterns used in industry for standard
problems.
ost of the time patterns are used not for some
special reason but for more manageability and ease of
change.So if you have a small application than it's
ok but if you are working on big application which
are needed to be maintained over a time and changes
are frequent.Than its better to start learning about
patterns because their will be problems which right
now you can't see but eventually you have to take
care of.That is either incorrect or phrased poorly.
Patterns come about because someone analyzes different existing code bases and notes that there are similarities in the way they are built.
It isn't that they are easier to maintain but rather that because the pattern has similarities it is easier to comprehend, understand the limitations, understand the possible related patterns, etc. That might lead to easier maintainance but it isn't the reason. The reason is because, if and only if, the requirements/architecture lead to a situation where that pattern could be properly used.

Help on DAO pattern

Hello!
I'm having a problem implementing the DAO pattern.
Suppose that I have two database tables:
emp(id, name, sex, deptid)
dept(id, name)
If I follow the DAO pattern, I use two DAO interfaces, one for each
table, and "entity". EmployeeDAO, and DepartmentDAO.
(I'm using an abstract factory to create storage-specific DAOS)
These DAOs return instances of Employee, and Department, or lists of them. (ValueObjects).
This is all great and works very well, but suppose I want to produce the following
presentation on the web:
deptname | male | female
Dept A   | 10   | 20
Dept B   | 15   | 30In essense, this is a request for all the departments.
I would iterate through this list, and want to display how many
males, and how many females there are in each department.
Should this be in the DepartmentDAO, or in a separate DAO?
Or should this be put in some BusinessDelegate?
That is, DepartmentDelegate.countMales(dept);
Or should I put a method in the ValueObject Department that in turn uses the DAO to count males?
Or should I load the number of females into the valueobject when fetching it from the
database in the first place?
Or should I construct a specialized view of the department such as:
class StupidViewOfDepartment
   private Department dept;
   private int males;
   private int females;
   public StupidViewOfDepartment(Department dept, int males, int females){
   public int numFemales();
      return females;
   public int numMales(){
      return males;
}...having some class return a collection of this specialized view?
In that case, which class would that be?
A new DAO or the DepartmentDAO?
All classical examples of DAO patterns that I can find, fails to adress
other issues than just retreiving a single Employee, or a list of them.
Can someone advise me on this?

You said:
My problem might be, that the data I'm asking for, is not distinct objects, business objects,
but a "new type of object" consisting of this particular information, that is
deptname, numMales, numFemales.
EXACTLY! You are querying for data that is either aggregate, a combination of various other business objects or a very large set of known business objects. In any of these cases, you probably don't want to use a vanilla DAO. Write a dedicated search DAO. Depending on your OO purity level and time horizon, you could make VO's for the search request or the results returned.
You said:
I'd like to think of this as report functionality, or aggregate reports.
I'm good at database programming, and I'm particularly good at optimization,
so if I cannot do this the good-looking way, I can always resort to brutal techniques...ehum
PERFECT! If you are great at database operations, and you know exactly how you want to optimize a given search, then give it its own DAO. The main problem with the object->relational boundary is that most cookie-cutter solutions (ala entity beans with CMP) cannot even remotely appropach the optimization level of a good database programmer. If you want to optimize a search in SQL or a stored procuedure, do that. Then have a dedicated search DAO use that funcitonality. (If you want to do it "right", make a search Factory object that will return various implementations, some may be vendor-specific or optimized, others might be generic; the Factory simply returns a search DAO interface, while specific implementations can concentrate on the task at hand. Swapping implementations with the same interface should be trivial).

DAO Pattern Confusion

Hello,
Have started developing with J2EE recently, moving up from J2SE. With regards to persistance of data to a database I have been looking at the DAO pattern. I am a little confused about this pattern, so I hope someone may be able to clear a few things up.
As I understand it the Transfer Object (TO) can be a simple java bean with getter and setter methods.
The DAO can only have four methods, create, read, update and delete. I am a little confused here, because as I see it, we can only have these four methods to read/write from/to the TO.
Isn't this very limiting? For example, the update statement of the DAO will have to have a TO which has already been populated, for this to occur an already populated TO has to be generated (a read on the DAO) and then the required values changed via the get/set methods of the TO. Then a method of the DAO has to be called to persist this data to the database.
This would cause difficulties if we wanted to implement optimistic locking for example, where we wanted to check if a row had been changed before commiting the change (to prevent lost updates).
Would it not be better to have many methods in the DAO, and a customer TO for each one? E.g. methods such as:
TO to = new TO();
to.setState("new");
to.setWhere("old");
dao.updateState(TO to)
Such a design would let us update the state of a row in the database to "new" where the state previously was "old" and hence be a basic implementation of optimistic locking.
Or are we completely missing the point!
Many thanks,

>>
IMO, this model is broken. TO's, as traditionally
implemented, are read-write. In most cases, it is
easier to code a TO as read-only. Provideinstance
values in the constructor and then expose onlygetter
methods. One possible implementation is to havethe
DAO and the TO (or preferably model object) in the
same package. Make the constructor of the TO
protected (or package private). Then, the DAO can
initialize values from the persistent store, but
users of the TO will only be able to read thevalues
retrieved. If this model becomes limiting, you
should realize that you are now allowing mutator
methods. IMO, your TO should now be afully-fledged
domain model object.
I disagree. And apparently others do as well because
your model is the way that J2EE first represented
DTOs (as a "Value Object").
I will refer you to Bloch, et. al. Immutable objects are easier to code and to test.
I suppose my reason for this would be that most of
the work in other layers involves sending mutated
data back. With your pattern this requires that the
user, every single time, create a new object, copy
the old data to the new, and then send the new object
back.
You are asserting the 'new' keyword is onerous?
Extra work with no gain.
I agree. There is an ever so slight overhead to creating a new, immutable object. However, limiting the possible states of an object, by definition, lowers its entropy and hence the possibilities one needs to test.
The DAO can only have four methods, create,read,
update and delete. I am a little confused here,
because as I see it, we can only have thesefour
methods to read/write from/to the TO.
This is roughly what a database allows. However,
what of commonly used parent-child or foreign-key
relationships? You may retrieve an account holder
and his/her present balance 90% of the time inyour
system. Do you want two separate TO's and DAO's
here? Or is this a case where a DAO can constructa
graph of objects in memory as an optimization?
Yes. Issuing a single SQL query to fetch a parent child relationship is more efficient than fetching foreign keys in a parent table and querying for each child. Maybe we are in fact on the same page, maybe not. But I am referring to releationships such as many-to-many that pose difficulties to O/R mappers. The same would hold true for a design where each table row corresponds to an object.
There are several other J2EE patterns for complex
relationships.
I am not sure I have ever encountered a need for
those though.
Other than chaining various Collection classes, neither have I. However, a fairly rich set of relationships (hierarchical, sequential, dependent, etc.) can be constructed from these.
>>
This would cause difficulties if we wanted to
implement optimistic locking for example, wherewe
wanted to check if a row had been changed before
commiting the change (to prevent lost updates).
I would not implement this myself. As Duffy has
alluded to, Hibernate and other O/R mapping
technologies maintain the state of an object andthe
state when it was retrieved, allowing theframework
to update only modified fields when needed.
Interesting.One of the best benefits that Hibernate offers out of the box, that and lazy loading. Though like all things, these too can be abused.

DAO pattern and Java Persistence API

Hi
This is a question for anyone who might be familiar with the standard DAO design pattern and the Java Persistence API (JPA - part of EJB3). I'm new to this technology, so apologies for any terminology aberrations.
I am developing the overall architecture for an enterprise system. I intend to use the DAO pattern as the conceptual basis for all data access - this data will reside in a number of forms (e.g. RDBMS, flat file). In the specific case of the RDBMS, I intend to use JPA. My understanding of JPA is that it does/can support the DAO concept, but I'm struggling to get my head around how the two ideas (can be made to) relate to each other.
For example, the DAO pattern is all about how business objects, data access objects, data transfer objects, data sources, etc relate to each other; JPA is all about entities and persistence units/contexts relate to each other. Further, JPA uses ORM, which is not a DAO concept.
So, to summarise - can DAO and JPA work together and if so how?
Thanks
P.S. Please let me know if you think this topic would be more visible in another forum (e.g. EJB).

Thanks, duffymo, that makes sense. However ... having read through numerous threads in which you voice your opinion of the DAO World According to Sun, I'd be interested to know your thoughts on the following ...
Basically, I'm in the process of proposing an enterprise system architecture, which will use DAO as the primary persistence abstraction, and DAO + JPA in the particular case of persistence to a RDBMS. In doing so, I'd like to illustrate the various elements of the DAO pattern, a la the standard class diagram that relates BusinessObject / DataAccessObject / DataSource / TransferObject (http://java.sun.com/blueprints/corej2eepatterns/Patterns/DataAccessObject.html). With reference to this model, I know that you have a view on the concept of TransferObject (aka ValueObject?) - how would you depict the DAO pattern in its most generic form? Or is the concept of a generic DAO pattern compromised by the specific implementation that is used (in this case JPA)?

There was a problem updating InDesign CC For more information see the specific error below. Update Failed Download error. Press Retry to try again or contact customer support.(49)

Posted the entire text from the error window, when trying to update, using the normal NON-TECHIE way to update any and all Adobe CC products, via the Creative Cloud updater installed when Adobe Creative Cloud subscription was purchased when first offered.
The following occurs, ad nauseam:
There was a problem updating InDesign CC
For more information see the specific error below.
Update Failed
Download error. Press Retry to try again or contact customer support.(49)
Here's the crux of my frustration:
(1) Customer Service is NOT contact-able, to receive LIVE help.
(2) There is NO way for me to mitigate this "Download error", being a student learning InDesign, and NOT in any way capable of tweaking folders/files here and there.
Therefore, the real question:
Given that a significant number of subscribers are having the above referenced issue with attempting to download the current update for InDesign, WHAT ARE WE SUPPOSED TO DO, in order to get our contractually paid-for updates to our legally and contractually paid-for Adobe software, specifically in my case, InDesgin's current update?
Please, NO TECHNICAL mumbo-jumbo which most likely will cause the overwhelming majority of users, like me, to seriously corrupt their computer files, but rather an honest, straightforward "what to do" from real CS/Engineers working for Adobe, as to how to FIX this issue, period.
===========================================================
UPDATE:
Here is a way in which I think I was able to "update" my InDesign CC application:
(1) Sign-In to your Adobe Account
https://www.adobe.com/
(2) Click on the MENU icon
(3) Click on the product InDesign icon
Your browser should display the page for Adobe InDesign CC
https://www.adobe.com/products/indesign.html?promoid=KLXLU
(4) Click on the Download icon,
Your browser should now display the page to download InDesign,
https://creative.adobe.com/products/download/indesign
(5) a Pop-Up window should open, and display:
Launch Application
This link needs to be opened with an application.
with the first option to select being the CreativeCloud(URIHandler)
(5) Select this application and click OK.
What happened when I followed steps (1) thorugh (5) is that:
(a) InDesign CC(2014) was installed,
(b) InDesign CC, updated, and then
(c) InDesign CC(2014), also updated.
Why this all worked, is a mystery to me.
Looks like a separate, "new" version of InDesign, InDesign CC(2014), was installed, the existing "old" InDesign was updated, and then the newly installed Indesign CC(2014) was further updated.
A BIT MORE, when I launched my InDesign CC app, and checked to see if there were Updates Available, there in fact was an Adobe InDesign CC 64 bit (9.2.2) update.
I clicked on UPDATE and my "old" InDesign CC app was "successfully updated."
FURTHER INFO: I may have neglected to list some important info ... OS: Windows 8.1 Pro with Media Center, 64-bit
Confused, I am able to launch BOTH of these apps, and hopefully I may use one of these versions of the InDesign CC app, to do some InDesign work.
Will keep y'all posted!

"We couldn't create a new partition or locate an existing one. Form more information, see setup log files"

Ok so back in August 2014 I succuesfully used bootcamp to install Windows 10 Tech preview. It worked great until March of this year when Windows issued an update (Which I had no control over). After this update the R9 4GB graphics card driver stopped working. I contacted Apple/AMD/Microsoft but was unable to fix this problem.
So, I uninstalled Windows 10 through bootcamp and restored the drive to a single partition. I purchased windows 8.1 and downloaded Windows Enterprise edition (as this comes as an ISO file) and started the process again with Bootcamp. Everything works great until I get to the installation of windows.
I did the same as last time (formatted the Bootcamp partition) and tried to continue the installation. I now get the following message:
I have tried a complete reinstall of the system twice (back to factory settings) but still the same issue. I have also tried using Windows 10 Tech preview but still the same issue. (I only have my remote drive with the ISO file connected to the mac and have tried with a USB stick)
Any ideas would be much appreciated! Thanks

Thank you for your prompt response. Please see below:

Installing a trial version of the Illustrator and InDesign App in Creative Cloud on my Mac is impossible. Keep getting 'Installation failed' notices. More information gives 0 fatal error(s), 0 error(s). Already repaired disk permissions in Disk Utility but nothing seems to work. Exit code: 7.

I am using the Order Analysis Toolkit and want to get more information about the compensation for "Reference Signal Processing", which is scarce in the manuals, the website and the examples installed with the toolkit.

I am using the Order Analysis Toolkit and want to get more information about the compensation for "Reference Signal Processing", which is scarce in the manuals, the website and the examples installed with the toolkit.
In particular, I am analyzing the example "Even Angle Reference Signal Processing (Digital Tacho, DAQmx).vi", whose documentation I am reproducing in the following:
DESCRIPTIONS:
This VI demonstrates how to extract even angle reference signals and remove the slow-roll errors. It uses DAQmx VIs to acquire sound or vibration signals and a digital tachometer signal. This VI includes a two-step process: acquire data at low rotational speed to extract even angle reference; use the even angle reference to remove the errors in the vibration signal acquired at normal operation.
INSTRUCTIONS:
1. Run the VI.
2. On the DAQ Configurations tab, specify the sample rate, samples per channel, device and channel configurations, and tachometer channel information.
NOTE: You need to use DSA PXI-447x/PXI-446x and PXI TIO device in a PXI chassis to run this example. The DSA device must be in slot 2 of the PXI chassis.
3. Switch to Extract Even Angle Reference tab. Specify the number of samples to acquire and the # of revs in reference which determines the number of samples in even angle reference. Click Start to take a one-shot data acquisition of the vibration and tachometer signals. After the acquisition, you can see the extracted even angle references in Even Angle Reference.
4. Switch to the Remove Slow-roll Errors tab. Click Start to acquire data continuously and view the compensate results. Click Stop in this tab to stop the acquisition.
ORDER ANALYSIS VIs USED IN THIS EXAMPLE:
1. SVL Scale Voltage to EU.vi
2. OAT Digital Tacho Process.vi
3. OAT Get Even Angle Reference.vi
4. OAT Convert to Even Angle Signal.vi
5. OAT Compensate Even Angle Signal.vi
My question is: How is the synchronization produced at the time of the compensation ? How is it possible to eliminate the errors in a synchronized fashion with respect to the surface of the shaft bearing in mind that I am acquired data at a low rotation speed in order to get the "even angle reference" and then I use it to remove the errors in the vibration signal acquired at normal operation. In this application both operations are made in different acquisitions, therefore the reference of the correction signal is lost. Is it simply compensated without synchronizing ?
Our application is based on FPGA and we need to clarity those aspects before implementing the procedure.
Solved!

Unable to load Facebook on MBP in any browser - looking for more information

I have searched the Internet far and wide trying to figure out what is wrong, but every suggestion I have tried has failed. So here is my question:
Last night, I turned on my MBP and tried to log onto Facebook. I use Google Chrome as my default browser. Chrome was unable to connect to www.facebook.com. I tried in Safari also with no luck. Facebook seems to be the only web site I cannot connect to. Over the same wifi connection, I was able to connect to Facebook from my home PC, my iPad, and my iPhone (the actual web site and thru the app).
This morning, I brought my MBP to work to try again. Same problem. I cannot access Facebook from my MBP, but I can from my work PC and my other iOS devices. I even tried turning Personal Hotspot on my iPad and connected my MBP to that. Still no luck.
Based on everything I've read online, I've done many things to try to resolve this. I've cleared my cache and cookies, I've rebooted my MBP several times, I've flushed my DNS. I've even tried using Open DNS. I even tried some of the more ridiculous sounding ideas, like changing the date on my MBP. I am currently running Sophos in hopes that maybe the reason this is happening is because of some malware or trojan or something. The only thing I HAVEN'T done yet is completely reinstalled Mountain Lion. Honestly, I would rather avoid having to try this approach, as it seems that is a slightly extreme approach to fixing what should be a relatively straightforward problem to diagnose.
I've been racking my brain, trying to think of any updates I could have done in the last day or two that might have caused this very specific problem. According to System Information, the last set of updates I probably made right before this problem manifested were for Microsoft Office. I'm showing "Office 2011 14.2.5 Update", "Microsoft Error Reporting for Mac", and the very cryptic sounding "Plugin" as all having been installed yesterday. Based on the times each was installed, "Plugin" was not installed with the Office updates, so I'm wondering if maybe that is the culprit. Unfortunately, I have no more information than that.
I guess what I'm looking for are ideas on how I can better diagnose what is going on. I've tried the solutions people have posted online to no avail. If I knew what was happening behind the scenes, that might help me figure out what I really need to do to get this working again, before I'm forced to resort to a reinstall of Mountain Lion that may or may not even resolve this issue. If anyone has better ideas on what could be wrong or ways in which I can get more information to better diagnose this problem, please post them here. Thank you!

I didn't think reinstalling was gonna do me any good except for getting rid of every single thing I have ever installed since getting this MBP. I'm thinking it has to be something that is on my computer causing this, especially since it only affects my ability to get to this one site and I only started seeing this problem yesterday.
So, I went ahead and disabled all my Chrome extensions and I don't have any Safari extensions at all. That didn't fix my issue.
I've been trying to run Sophos on here, thinking that maybe I've got a Trojan or some kind of malware, but it never seems to finish a full scan of my hard drive. That "Plugin" that I mentioned above has me very suspicious, except that whatever that is, it's been on my computer since basically when I first got it. Maybe it's malicious, or maybe it's just a poorly named piece of software. In any case, it got updated last night around 11pm, about the same time I noticed my problem. After trying everything I have, it's hard for me to overlook that as coincidence.
But, where do I go to gain more information about what that could be? I should mention that this MBP is basically my first Apple computer. I've been a PC guy (still am mostly) forever, but I finally dove in and got a Mac to start iOS development. So I'm sure there are ways to get more information than I am currently aware of.
Also, apologies if I posted this in the wrong forum.

Hi Guys,
I am creating the library using object model with custom content type. When i am opening document from custom content type, the meta data fields are not displaying in the document and throwing below error.
The document information panel was unable to load. the document will continue to open. For more information, contact your system adminsitrator.
Document Information Panel cannot open a new form.
The form contains schema validation errors.
Content for element '{http://schemas.microsoft.com/office/2006/metadata/propertiesRoot}properties' is incomplete according to the DTD/Schema.
Expecting: {http://schemas.microsoft.com/office/2006/metadata/properties}properties.
But after saving the document, then meta data is enabled.
Thanks in advance for suggested solutions.

Hi,
For a better troubleshooting, I suggest to do as follows:
1. Please try to update the Location column's schema by following the steps below.
1) Go to Site Settings -> "Site Columns"
2) Click on "Location", after the page is opened. Don't modify any settings, click "OK" to forcibly update the field's schema.
2. Re-edit the document information panel template to see if the issue still occurs.
Please go to the Library setting > click the corresponding content type(need to enable managed of content types in Advanced settings) > click Document Information Panel settings.
3. Here are some similar links about your issue, please take some time to look at them:

If the issue still occurs, please check if the command below can help(change the site URL and the library name in the code):
Apply-Fix -siteUrl "http://your site URL "
function Apply-Fix($siteUrl)
clear
Add-PSSnapin "Microsoft.SharePoint.Powershell" -ErrorAction SilentlyContinue # -EA 0

foreach ($spwTarget in (Get-SPSite $siteUrl).RootWeb.Webs) {
Write-Host "Checking Web: " $spwTarget.Url
$list = $spwTarget.Lists["your library name"]
$fields = $list.fields
foreach($field in $fields)
if($field.SourceId -eq '{$ListId:your library name;}')
$schemaxml = $field.SchemaXML
$schemaxmldata = [xml]$schemaxml
$schemaxmldata.Field.SetAttribute("SourceID", $list.ID)
$schemaxml = $schemaxmldata.get_InnerXml()
$field.SchemaXML = $schemaxml
$field.Update()
Write-Host "Fixed" $field.Title "field in the library"
Write-Host "Done."
