What kind of view object should I create for this data model?

I have an entity that has several dates. The dates are stored in a table separate from the entity, each entity date has a date type (open, close, interview, etc) associated with it. The DBAs idea (who else of course!) was to have the flexibility to add new types of dates for entities when needed.
So you have tables like this -
Table: EntityTable
Columns: EntityId, EntityName
Table: DatesTable
Columns: EntityId, Date, DateTypeCd
I need to display an editable ADF form where I can update the entity and the entity dates
The ADF form would contain something like this -------
Entity Name: []
Opening Date: []
Closing Date: []
Interview Date: []
What kind of view object would I need to create to achieve this?

That would be a master-detail relation 1-* between 'entity' and 'entity dates'. If your dba has set up the foreign key association in the db and you use the wizard to create the business objects, jdev pick up the relation and create the correct master detail relation in the vo layer for you.
By the way naming a table 'entity' is not a good idea when working with ADFbc. We all talk about entities when we relate to a business object (in this case a row of a table or entity object or EO). So it's hard to distinguish the two, your specific table 'entiyt' and the common term entity or EO which can be a row of any table.

What kind of external drive should I get for my macbook pro for backups etc

what kind of external drive should I get for my macbook pro for backups and storage

Hi, i have a Mercury Elite-AL Pro from OWC, www.otherworldcomputung.com
this is the one;
http://eshop.macsales.com/item/Other%20World%20Computing/MEAQ7S1TB32M/
have had this for over two years, moved around a lot with the drive, ( to date ) no problems, they have good after sales support; give them a call if you need info.
There are a lot of drives out there as others here will let you know, there are good NAME drives but they also fail, POPULAR drives also fail, select the one you are happy with for your system and how you plan to use.
i suggest if $ is not a problem get a big drive you will find someting to put on it and is better.
hope this helps.

What kind of version checking should be done for applications using SQLDBC

Hi,
This query is regarding the kind of version checking that an application should do.
Currently I am building my application in MaxDB version of 7.6.05.09, which is the community edition available on the sdn download site currently, this will change to the enterprise edition once we have finalized everything in terms of code and packging etc....
Now when the application is shipped to customer site, what kind of version checking should the application do to ensure that the version of library/kernel/client/sdk it has been built with is consistent with the one that is installed at the customer site.
From what i see SQLDBC exposes the following method for getting version related information.
char * SQLDBC_Environment_getLibraryVersion(SQLDBC_Environment* hdl);
char *getSDKVersion();
SQLDBC_Int4 SQLDBC_Statement_getKernelVersion(SQLDBC_Statement* hdl); (Note: Wondering why should a handle to SQLDBC_Statement be needed to find the Kernel version)
Just to give you little more hint of what i am talking about, for MySQL database we use the functions
mysql_get_client_version and mysql_get_server_version and check that the values returned by these functions are less than the value which was used at build time.
Regards
Raja

Hello Raja
From the documentation:
const char* SQLDBC::SQLDBC_Environment::getLibraryVersion ()
Returns the version of used SQLDBC runtime.
This is the version of the used SQLDBC library. The version of the loaded
runtime may differ from the version inidacted in the used header. It is our
aim that newer versions of the runtime will run with old applications without
the need to be re-compiling.
Therefore, for compatibility checks, use getLibraryVersion.
getKernelVersion is also available from the connection:
SQLDBC_Connection::getKernelVersion()

What kind of Mac configuration should I get for video editing

I have been using after effects and premiere pro a lot and has been experiencing lots off lag, even when I am using the Internet. What Mac configuration should I get for this type of editing?

When I was doing more video editing, two things mattered ..... a fast CPU and lots of memory. Having the horsepower to handle activities like rendering really helps.
On lag, while it certainly can be application-driven, you might look over this FAQ for some ideas.
If you haven't already, you might also ask in the FCP dicussion here.

What query should be created for this case

Here are those classes:
Folder{
    String name;
    @ManyToOne
    Subject owner;
Subject {
    String name;
}What query should I create in order to: find out if there is an actual Folder for a Subject with the name X in the database ?
Actually, the question is kinda stupid, but im not experienced with queries....

Your naming is confusing. Subject and owner are two very different things.
If I had two tables like this:
CREATE TABLE IF NOT EXISTS owners
    owner_id bigint not null auto_increment,
    name varchar(80),
    primary key(owner_id)
CREATE TABLE IF NOT EXISTS folders
    folder_id bigint not null auto_increment,
    name varchar(80),
    owner_id bigint
    primary key(folder_id),
    foreign key(owner_id) references(owners)
);I'd write the JOIN query this way:
SELECT f.name, o.name
FROM folders as f, owners as o
WHERE o.owner_id = ?
AND o.owner_id = f.owner_idYou realize, of course, that if you're using EJB3 as the annotations suggest, that you don't write any SQL. EJB3 generates it dynamically for you.

What kind of net connection should I have for a DataGuard system?

I want to construct a DataGuard system on 3 PCs( all with the RHEL5.0 OS and just for test purpose). But I don't know what kind of connection should I make between the 3 PCs? Shoud I use a router?
Thank you for any answer.

You don't really need a router for this testing.
a simple back to back connection would work.
or a hub even.
routers tend to get more expensive.

Don't know what kind of application I should use to make this kind of proj.

I am going to make a project and I am not sure what kind of program would work for this document I want to make. The project I would like to make is of a type like a family tree, or a reverse sports playoff grid, where you start out with a few headers that branch out laterally and are linked with lines (just like a family tree graph) to many different headers. I want to have each of these headers as hyperlinks that you can click on to read more text/data/pictures about each header. I want to be able to add and edit it after I created it without major adjustments to the whole thing. Is this a clear question? Any help would be great. Thanks.

What kind of virus protection should I get for my iMac?

I tried downloading AVG, which I use for my PC laptop, but it didn't work.

1. This comment applies to malicious software ("malware") that's installed unwittingly by the victim of a network attack. It does not apply to software, such as keystroke loggers, that may be installed deliberately by an intruder who has hands-on access to the victim's computer. That threat is in a different category, and there's no easy way to defend against it. If you have reason to suspect that you're the target of such an attack, you need expert help.
If you find this comment too long or too technical, read only sections 5, 6, and 10.
OS X now implements three layers of built-in protection specifically against malware, not counting runtime protections such as execute disable, sandboxing, system library randomization, and address space layout randomization that may also guard against other kinds of exploits.
2. All versions of OS X since 10.6.7 have been able to detect known Mac malware in downloaded files, and to block insecure web plugins. This feature is transparent to the user, but internally Apple calls it "XProtect." The malware recognition database is automatically checked for updates once a day; however, you shouldn't rely on it, because the attackers are always at least a day ahead of the defenders.
The following caveats apply to XProtect:
It can be bypassed by some third-party networking software, such as BitTorrent clients and Java applets.
It only applies to software downloaded from the network. Software installed from a CD or other media is not checked.
3. Starting with OS X 10.7.5, there has been a second layer of built-in malware protection, designated "Gatekeeper" by Apple. By default, applications and Installer packages downloaded from the network will only run if they're digitally signed by a developer with a certificate issued by Apple. Software certified in this way hasn't necessarily been tested by Apple, but you can be reasonably sure that it hasn't been modified by anyone other than the developer. His identity is known to Apple, so he could be held legally responsible if he distributed malware. That may not mean much if the developer lives in a country with a weak legal system (see below.)
Gatekeeper doesn't depend on a database of known malware. It has, however, the same limitations as XProtect, and in addition the following:
It can easily be disabled or overridden by the user.
A malware attacker could get control of a code-signing certificate under false pretenses, or could simply ignore the consequences of distributing codesigned malware.
An App Store developer could find a way to bypass Apple's oversight, or the oversight could fail due to human error.
For the reasons given above, App Store products, and other applications recognized by Gatekeeper as signed, are safer than others, but they can't be considered absolutely safe. "Sandboxed" applications may prompt for access to private data, such as your contacts, or for access to the network. Think before granting that access. OS X security is based on user input. Never click through any request for authorization without thinking.
4. Starting with OS X 10.8.3, a third layer of protection has been added: a "Malware Removal Tool" (MRT). MRT runs automatically in the background when you update the OS. It checks for, and removes, malware that may have evaded the other protections via a Java exploit (see below.) MRT also runs when you install or update the Apple-supplied Java runtime (but not the Oracle runtime.) Like XProtect, MRT is presumably effective against known attacks, but maybe not against unknown attacks. It notifies you if it finds malware, but otherwise there's no user interface to MRT.
5. XProtect, Gatekeeper, and MRT reduce the risk of malware attack, but they're not absolute protection. The first and best line of defense is always your own intelligence. With the possible exception of Java exploits, all known malware circulating on the Internet that affects a fully-updated installation of OS X 10.6 or later takes the form of so-called "trojan horses," which can only have an effect if the victim is duped into running them. The threat therefore amounts to a battle of wits between you and the malware attacker. If you're smarter than he thinks you are, you'll win.
That means, in practice, that you never use software that comes from an untrustworthy source, or that does something inherently untrustworthy. How do you know what is trustworthy?
Any website that prompts you to install a “codec,” “plug-in,” "player," "extractor," or “certificate” that comes from that same site, or an unknown one, is untrustworthy.
A web operator who tells you that you have a “virus,” or that anything else is wrong with your computer, or that you have won a prize in a contest you never entered, is trying to commit a crime with you as the victim. (Some reputable websites did legitimately warn visitors who were infected with the "DNSChanger" malware. That exception to this rule no longer applies.)
Pirated copies or "cracks" of commercial software, no matter where they come from, are unsafe.
Software of any kind downloaded from a BitTorrent or from a Usenet binary newsgroup is unsafe.
Software that purports to help you do something that's illegal or that infringes copyright, such as saving streamed audio or video for reuse without permission, is unsafe. All YouTube "downloaders" are in this category, though not all are necessarily harmful.
Software with a corporate brand, such as Adobe Flash Player, must be downloaded directly from the developer’s website. If it comes from any other source, it's unsafe.
Even signed applications, no matter what the source, should not be trusted if they do something unexpected, such as asking for permission to access your contacts, your location, or the Internet for no obvious reason.
6. Java on the Web (not to be confused with JavaScript, to which it's not related, despite the similarity of the names) is a weak point in the security of any system. Java is, among other things, a platform for running complex applications in a web page, on the client. That was always a bad idea, and Java's developers have proven themselves incapable of implementing it without also creating a portal for malware to enter. Past Java exploits are the closest thing there has ever been to a Windows-style virus affecting OS X. Merely loading a page with malicious Java content could be harmful.
Fortunately, client-side Java on the Web is obsolete and mostly extinct. Only a few outmoded sites still use it. Try to hasten the process of extinction by avoiding those sites, if you have a choice. Forget about playing games or other non-essential uses of Java.
Java is not included in OS X 10.7 and later. Discrete Java installers are distributed by Apple and by Oracle (the developer of Java.) Don't use either one unless you need it. Most people don't. If Java is installed, disable it — not JavaScript — in your browsers.
Regardless of version, experience has shown that Java on the Web can't be trusted. If you must use a Java applet for a task on a specific site, enable Java only for that site in Safari. Never enable Java for a public website that carries third-party advertising. Use it only on well-known, login-protected, secure websites without ads. In Safari 6 or later, you'll see a lock icon in the address bar with the abbreviation "https" when visiting a secure site.
Follow the above guidelines, and you’ll be as safe from malware as you can practically be. The rest of this comment concerns what you should not do to protect yourself from malware.
7. Never install any commercial "anti-virus" or "Internet security" products for the Mac, as they all do more harm than good, if they do any good at all. Any database of known threats is always going to be out of date. Most of the danger is from unknown threats. If you need to be able to detect Windows malware in your files, use the free software ClamXav— nothing else.
Why shouldn't you use commercial "anti-virus" products?
Their design is predicated on the nonexistent threat that malware may be injected at any time, anywhere in the file system. Malware is downloaded from the network; it doesn't materialize from nowhere.
In order to meet that nonexistent threat, the software modifies or duplicates low-level functions of the operating system, which is a waste of resources and a common cause of instability, bugs, and poor performance.
By modifying the operating system, the software itself may create weaknesses that could be exploited by malware attackers.
8. ClamXav doesn't have these drawbacks. That doesn't mean it's entirely safe. It may report email messages that have "phishing" links in the body, or Windows malware in attachments, as infected files, and offer to delete or move them. Doing so will corrupt the Mail database. The messages should be deleted from within the Mail application.
ClamXav is not needed, and should not be relied upon, for protection against OS X malware. It's useful only for detecting Windows malware. Windows malware can't harm you directly (unless, of course, you use Windows.) Just don't pass it on to anyone else.
A Windows malware attachment in email is usually easy to recognize. The file name will often be targeted at people who aren't very bright; for example:
♥♥♥♥♥♥♥♥♥♥♥♥♥♥!!!!!!!H0TBABEZ4U!!!!!!!.AVI♥♥♥♥♥♥♥♥♥♥♥♥♥♥.exe
ClamXav may be able to tell you which particular virus or trojan it is, but do you care? In practice, there's seldom a reason to use ClamXav unless a network administrator requires you to run an anti-virus application.
9. It seems to be a common belief that the built-in Application Firewall acts as a barrier to infection, or prevents malware from functioning. It does neither. It blocks inbound connections to certain network services you're running, such as file sharing. It's disabled by default and you should leave it that way if you're behind a router on a private home or office network. Activate it only when you're on an untrusted network, for instance a public Wi-Fi hotspot, where you don't want to provide services. Disable any services you don't use in the Sharing preference pane. All are disabled by default.
10. As a Mac user you don't have to live in fear that your computer is going to be infected every time you install an application, read email, or visit a web page. But neither should you have the false idea that you will always be safe, no matter what you do. The greatest harm done by security software is precisely its selling point: it makes people feel safe. They may then feel safe enough to take risks from which the software doesn't protect them. Nothing can lessen the need for safe computing practices.

What kind of screen protector should I use for my iPhone 6? Should I use one?

I'm looking for a screen protector for my brand new baby. To my dismay, it's hard to find one that "fits" because of the curved edges. I have ocd, not to mention that what isn't covered by a screen protector are usually crucial areas. Can anyone recommend anything? I always use a screen protector because I'm super paranoid. I throw my phone in my purse a lot where I feel like it will come in contact with one too many things that can scratch it. I don't have a ton of money to spend, sorry I'm a college student. Also, I don't like glass protectors. If I need one I'm looking for a film. Thanks in advance from a new iPhone 6 parent!

I have an iPhone 6 Plus but I thought I would try to help you out!! I use the Zagg Glass Invisible shield and I must say at first I loved it! It feels smooth and accepts input super well! It doesn't, however, go all the way to the edge of the screen which is weird, I agree. I've only had it for about a month now and its already chipped on the top edge by the speaker and its super annoying!! They will replace it for free but I'm not sure that I want another one that chipped so easily.
I've heard great things about the iloome screen mate and it goes all the way to the edge of the screen and covers the curved part. I know you said you don't like glass protectors but those are the best and if you get a good one you pretty much only need to replace it once a year so you pay a bit more up front but it lasts a lot better than just film ones. Hope that helps!!!!!

What kind of hard drive should I get for video editing on my MacBook Pro

I work in film preservation, which requires a lot of rendering of DPX files.
I currently have a late-2009 MacBook Pro. It's having a lot of problems such as freezing and overheating, so I think it might be best to just replace the hard drive. Any tips on ssd vs hdd for quick rendering performance? Also, the optical drive is not functional so if like to use that as extra hard drive space as well.
Don't know too much about hard drives, and I'd really appreciate any help.
Thanks in advance!

Thanks everyone,
The symptoms don't exactly correlate with the ones listed on the page about resetting the Systems Management Controller. Typically when I'm running a demanding program like After Effects or Compressor alongside Chrome, the screen will typically freeze up, though I retain control of the mouse. I can't click anything though, and it usually takes about a minute or two (after I've pressed command-option-esc) for the mac to start responding again. I think it's because I'm trying to make the mac do things it wasn't designed to do, such as run these processor-heavy programs. Lately it's also been freezing very frequently while playing Netflix. The movie just freezes, though I can still hear the sound continuing, and then in about a minute or two it will snap back to the currently playing part of the movie.
As far as overheating, I've made it possible for my mac to perform with these programs by either keeping it on an icepack or heavily ventilated with an exterior fan. It seems that after heavy bouts of using these programs though, the freezing frequency and seriousness is worse. If I don't keep the mac really well ventilated and it gets too hot, the screen just goes black, everything stops, and then in a few seconds it pops back as if nothing happened, running normally.
The model of my mac is:
MacBook Pro (13-inch, Mid 2009)
MacBookPro5,5
MB991xx/A
13.3"/2.53/2X2GB/250-5400
However, I did add some more RAM when I go the computer to help it along.
Thanks again for all and any help! It's very much appreciated.

What kind of real time problems and issues arise in Data Modelling

Hellooo experts,
I am not a BW expertise, so just want to gather some knowledge on Problems and issues related to DATA MODELLING, if any body have a document or a link can you please snd it to [email protected] or reply to this post. I promise to reward you for proper answers hope this is the way i say thanks for your help.
kishore

hi kishore,
The first and most important problem is to understand Clients requirement. Clients even some time not aware of how to utilize efficiency of BW, as they are very much use to with traditional SAP R/3 reporting. So most of time we have to suggest options to client.
If we come to technical aspect, than identifying Key Figures and Characterstics is the most important task. And how you map that to available infoobjects. Attributes also plays major roles, like which attributes is better to use as navigational one and which as exclusive attribute.
Their is long list for data modelling issues, its better you refer either Mastering BIW book by Mac'Donalds. And SAP Help Library is also having good material.

kamaljeet

Creating Entities for this data model

Hi guys,
I have these 3 tables:
create table employee_a
( employee_id int not null primary key ,
first_name varchar(50) not null ,
last_name varchar(50) not null )
create table manager_b
( id int not null primary key ,
manager_employee_id int not null foreign key references employee_a(employee_id) ,
subordinate_employee_id int not null foreign key references employee_a(employee_id) )
create table user_c
( user_id varchar(20) not null primary key ,
user_password varchar(100) not null ,
employee_id int null foreign key references employee_a(employee_id) )* All the employees are defined in employee_a table.
* If an employee is also a manager then its defined in manager_b table. That employee's id is defined in manager_employee_id column while his/her's subordinates employee ids are defined in subordinate_employee_id column.
* All the users of the system are defined in user_c table. If user of the system is also an employee then its defined in employee_id column of user_c table. If user of the system is not an employee then employee_id column is blank of user_c table.
The data may be like this:
insert into employee_a values (1, 'Mark', 'Benson')
insert into employee_a values (2, 'Joe', 'Young')
insert into employee_a values (3, 'Robert', 'Carbone')
insert into employee_a values (4, 'Wendy', 'Swistenenko')
insert into employee_a values (5, 'Tony', 'Lapolla')
-- Joe Young is manager of "Robert Carbone" and "Tony Lapolla"
insert into manager_b values (100, 2, 3)
insert into manager_b values (101, 2, 5)
-- Wendy Swistenenko is manager of "Mark Benson"
insert into manager_b values (102, 4, 1)
-- Users of the system who are also employees
insert into user_c values ('bensonM', 'password', 1)
insert into user_c values ('youngJ', 'test', 2)
-- A user of the system who is not an employee
insert into user_c values ('guest', 'pretty', null)My question is how to define Entities for these 3 tables for JPA. I am concerned about Inheritence Strategy to use.
Thanks

sorry, i couldnt understand your query..

I need in Formula Node to assign to the variable value 4000000000!!! What kind of variable it should be???

i've just tryed to write unsigned in32, but it does not understand 'unsogned'... But i need variable to be unsigned, because the max value = 4000000000... So, how can i solve this probleme???

Hi,
I don't see exactly what you're trying to do here.
Where do you want to assign the variable 4000000000 to? If you want it as an
input, just use a dbl, with only zeros behind the coma.
Note that an integer is a number without any decimals. An integer in LabVIEW
is this, but with an extra limitation that it can only be 32 bits... So a
dbl can be an integer.
If the input dbl is not an integer, use round, round to -inf or round to
+inf to make it one. This can also be done if the output needs to be an
integer.Inside the formula node floor(x), int(x), intrz(x) or ceil(x) can be
used to make integers.
I hope this is what you mean... I can't see any problems doing this.
Regards,
Wiebe.
