How do I make a database?

How do I make a database that I can access through a .jsp file? I have no idea how to create a database, if anyone could help me it would be greatly appreciated. Do I need certain drivers to access this database once it is complete?

First, you need a database. Oracle, Sybase, MS-Excess, etc. Anyone of these is fine. Once you have pick a database and created some records, you are ready to make a connection or write a java class to access your database record. In order to access the database, for example 'sybase', you need the sybase driver to communicate between your java code and sybase. you can get this 'driver' from sun website or vendor's website.
After that is pretty simple, all you need to do is built a SQL java class that will enable you to log on to the database and retrieve records( this can be find in java's web in how to write a sql class to connect with database).
take a step at a time, there are many details.

  • How can I make my database BC4J enabled?

    I try to deploy a BC4J project and I think my database is not BC4J aware because I used database browser from JDeveloper 3.2 and I browse SYS schema and no pachets oracle.jbo.* is outhere.Can someone to tell me wich is the steps I must follow for load this pachets in database?
    TIA

    JDeveloper will deploy the BC4J for you if you tell it to deploy to an Oracle RDBMS (8i or later). Assuming that the project uses BC4J...
    These would then be reflected in the loaded java packages.

  • How can I make an app with xcode that works like a news app? So that I can post articles on the app. Do I have to use a database or can I connect the app directly with my mac?

    How can I make an iphone app with xcode that worrks like a newspaper? So that I can post articles on the app while it is on appstore. Can I directly connect the app with my mac or do I have to connect it to a database?  Thanks

    Funny, I was thinking you'd want to use the prescribed deployment that Apple went to all the trouble to provide so you wouldn't trot down the garden path with some other implementation, only to find your app rejected with the admonition to use Newsstand after all...
    If you're all hot to ignore all that & DIY, why are you even asking...why not just go for it...

    You need to be a little clearer in what you're asking.
    You can't make any web site in SQL Server - it's a database engine, not a website tool.
    What you can do is create web sites that pull data from a back-end SQL Server, but the SQL server doesn't handle the client connection at all (that's handled by a web server such as Apache, IIS, or similar).
    There are many ways to build such a site including .NET, PHP, Perl and more (although I don't know all the options for Windows servers because they're not as common outside of corporate/enterprise networks).
    In either case, given your choice of development language (HTML, plus one of the PHP/Perl/.NET/etc. options), plus your database (SQL Server) plus your web server (IIS, Apache, etc.) you can make any web site you like (or, at least, you're capable of developing).
    If you want to opimize that web site for iPhones then there are many references on how mobile browsing differs from the desktop. I'd recommend this book as a reference (and, yes, I understand the irony of linking to a paperback book for web design guidance ). Googling mobile web design (or iPhone web design) might yield more results.

  • How can i make a connection between an application and a database over net

    dear sir
    how can i make connection between an appliction and a database over internet while the client side appliction is behind proxy and firewall
    for example how the live update of norton antivirus makes connection to the data server to make comparetions and get new virus definitions
    does that depend on sockets technology ?
    what references can guide me to the solution please?

    The ability to do so depends entirely on the JDBC driver implementation having some proxy method. It needs to recognize the HTTP or SOCKS proxy and use them to connect, and the firewall and proxy need to allow those specific port connections.
    To the best of my knowledge, all of these update utilities, e.g. live update for Netscape, Norton, etc., do not connect directly to the database. As it is, no sane security person would allow a database to be exposed to the Net. Rather, they connect using HTTP or HTTPS, which normally traverses firewalls just fine, to connect to a Web or application server on the far end. That application server then parses the request and retrieves whatever it needs to from the database.
    In other words, you cannot have a 2-tier client/server application. You need a 3-tier application:
    your client -> Web/app server -> database
    where the connection from your client to the Web/app server is over http or https through the firewall and proxies.
    Hope this helps.

  • How i can make multilanguage application .. take his vlues from database

    How i can make multilanguage application .. take his values from database
    and can change labels of massages , buttons ,text fields and name of columns in run time
    in jdevelpoer11g
    great thank

    Hi,
       I think that there is not a standard support for retrieving multilanguage texts from database in ADF. What we did is to implement our own ResourceBundle that retrieves the translated text from custom database tables. We also introduced a cache for optimizing the access to the translations.
    I hope this can help,

  • How to make new database connection using Oracle BI Interactive Dashboards

    Hi,
    I install Oracle BI Intelligence on my system.
    I am using Oracle BI Interactive Dashboard. Here we have default database connection.
    but now i want to use it for my own database. Can any body give me guideline how to
    make a new data base connection using this s/w or how to connect to my database so
    that i can make my own reports.
    I am using
    http://www.oracle.com/technology/obe/obe_bi/bi_ee_1013/saw/saw.html
    this link.
    i make odbc connection which is fine.
    but
    Restoring the Business Intelligence Presentation Catalog and Updating Metadata
    The third point blow above heading is not clear.
    Thanks

    Umesh - in order to build Answers and Dashboard content you must first setup a Physical model, then a Business model, followed by a Presentation Catalog/Subject Area.
    All these tasks are carried out using the Repository Administration Utility.
    1) Import your physical tables using OCI/ODBC into the physical layer.
    2) Build your model
    3) Deploy
    Then you're ready to start building answers/dashboards.
    Good Luck.

  • How do i make it so iTunes plays the music files from where i have chosen to store them?

    how do i make it so iTunes plays the music files from where i have chosen to store them as opposed to it scattering copies of my files into a myriad different folders based on the albums they came from when i'm not even interested in keeping whole albums?
    I recently converted myself to mac after having been a windows formatted person since the beginning of time. I use last.fm and the client scrobbler only supports iTunes on the mac (scobbling since Nov 06 and i'm now heavily dependant upon it as a means of discovering new music) - if you don't know what that means then take it for granted i have no option other than to use iTunes as my media player whn using the mac. And almost immediately upon using iTunes i was filled with horror.
    My tale of woe as follows: I copy all my mp3 files to folder X on my new mac. I copy my simple playlist in to that same folder X. The simple playlist simply lists all the files in folder X in the order i want to hear them in... simple right? And what happens the moment i start playing my simple list? Well you probably all ready know; itunes throws copies of all those files in to the air, scatters them to the four winds so each of them fall into a little folder of their own representing the album they might once have come from. I don't keep whole albums. For me the 'album experience' is a ruse to trick one into listening to weaker material. I only keep the concentrated goodness. I only put up with albums in a previous lifetime because in the days of vinyl i had no other choice apart from spending hours compiling mix tapes. Now i am liberated from these restrictions and have been for the 15 or so years i've been using a computer to listen to music. Until along comes iTunes forcing me backwards in time, frog marching me back into the past.
    That simple list i mentioned is my one and only playlist. This single playlist has been evolving for 15 years as tracks are added and removed and their position in the list changes because that song sounds amazing when heard after that other song whereas hearing this song after that song would be like pouring custard over your sausages (for me shuffling is an abomination). And so here is how i've managed this list and managed synchronization of said list and listed files with my mp3 player (currently a Zen).
    Adding a new file: After deciding that song is a keeper i will copy it into that simple folder that holds all my music and drop it in to a position on the list i deem most suited for it. Incidentally over this entire 15 year (i'm pretty sure it's been around that long) my media player has been winamp but for the reason previously mentioned i am unable to use winamp in mac world.
    Removing a file: fortunately winamp has an option to simultaneously remove a file from the list and the hard drive. And naturally so because after all if i no longer like a song then i want it expunged completely from life or at least from my hard drive and playlist. In the brave new world of iTunes i have to remove from the list there then delete the file from where iTunes copied it from and then the place iTunes copied it to.
    Editing the list: drag an item in the list to it's preferred location and select to save it as i would for any other file using any other application... well desktop type application as opposed to one that uses a database as its primary means of storage.
    Syncing with the mp3 player: copy drag drop playlist file from the simple folder on the hard drive to the simple folder on the mp3 player as i would for any other file. And then also copy drag drop the most recently created files from simple folder on hard drive to simple folder on player after having ordered them by creation date so as to make it easier to select the most recently created. After a while the mp3 player will fill up with the files no longer on the list so i will delete all files from player then re-copy all flies from simple folder on hard drive to simple folder on mp3 player.
    I do not make changes to the list on the mp3 player so synchronization needs only to go one way: from laptop to player.
    So all very simple. Apart from editing the positions of files in the list everything is managed by copy drag dropping and deleting files using windows explorer.
    But i'm in a mac and circumstances have forced me in to the corner of using iTunes. And this whole iTunes situation is terrifying for me as over the years i've heard horror stories about it deleting all of someone's music files. Perhaps this may have been by using the software incorrectly but even so, the very fact that it appears possible for this to happen simply by using the software incorrectly and the fact that it happens with some degree of frequency given the number of reports of this happening that i have heard of over the years on music discussion forums fills me with dread that i have to now use this software. And given the software's blatant disregard for the user's choice as to where to store his/her files it's no surprise that this happens. The software is pointlessly doing dangerous things with my data. Please make it stop.
    Please can i just at the very least make iTunes play the music from the folder i have chosen to put my files in and not copy those files here there and everywhere without my say so? Thankyou.

    option discovered in preferences. Really this and any feature that moves deletes or edits a users data should as far as possible be OFF BY DEFAULT. It shouldn't by default and without the users specific say do this dangerous and unnecessary thing without even letting the user know what it's doing!!! And then cause me a few hours (as i'm new to mac) searching for the option so as to switch it off. If i hadn't noticed the status cage declaring that it was copying files then i might never have twigged that this insane thing was occurring. And if i hadn't of noticed i would have been left maintaining the contents of the folder i copied the files to, the folder which as far as i was informed and so believed was also the location of the music files i was playing. How does Apple justify this 'genius' piece of software non-design? Surely it will hurt no one if this was off by default for new users - overall at least i dare say it would cause a lot less distress in the future for the unsuspecting public at large. Thanks for the support.

  • How do I make sure that my second-hand iPod is not a stolen product?

    My husband recently recieved an iPod shuffle from a friend of his. His friend told him he could have it since the friend didn't have a computer to download songs from or charge the iPod with. He states that he thought the iPod already had songs pre-recorded on it, and even if he used someone else's computer to get the songs, it's too much trouble. My husband had lent him some money to pay a utility bill and he was using this iPod that he just happened to have laying around to pay my husband back. I don't trust my husband's friend. How can I make sure that he isn't trying to push a stolen iPod off onto my husband? We haven't used it yet. My husband doesn't have much use for the shuffle, but I would love it, if only I could find out whether it was stolen or not. I don't want to take it to the police and start a big fight or get his friend in trouble, but if it is stolen I want to know so I can send it back to Apple or who ever owns it.

    Hi pyrausagi,
    You sound like a very honest and sensible person, who is taking very reasonable precautions against becoming a second victim of theft. Others on these forums have been less cautious and have lost their recent purchases.
    My suggestion would be to make sure the person offering the iPod shuffle is easily identifyable. Make sure he/she has a real address and you know what it is. Get a picture of the person and make sure they know you have it. If they are not above board I'm fairly sure they won't allow this.
    There are a number of online databases of stolen merchandise. Look them up and check the serial number of the iPod against these databases.
    Apple will not tell you if the item is stolen. Their phone agents that work with the public do not have that kind of information.
    Note that doing all this will not guarantee you don't get a stolen iPod. Only purchasing one new (or refurbished) from Apple or an authorized reseller can do that. It does, however, give you a better chance.
    Best of luck. Enjoy whatever iPod you get.

  • What can I tune to make the database use less memory in a 1GB ram notebook?

    Hi,
    Our notebook has 1GB ram only, running Windows XP Pro, Oracle10g Database, Oracle9i Application Server. It consumes about 1.4 - 1.5GB ram where it's already start using the virtual memory, therefore have some performance issue with it especially when try to startup the services.
    I'm not a DBA but I would like to get some advice on what and how can I tune the database to use less memory since the notebook is used for demo application only, so we save memory resource and make the notebook runs faster.
    Please advise.
    Thank you.

    In your case you could use 10g on XP. The only XP not supported is Home Edition.
    Coming back to the issue, since 9iR2 Oracle recommendation is to provide 1G for each AS node (infrastructure and middle tier). If you have this on the same box, by itself on the Enterprise install will consume more than 1G.
    Tuning 10g database won't make much difference. If you install AS 10gR2 it includes a 10gR1 Database as infrastructure database you could use for demo purposes.

  • How can I make a weekly 'to do' list?  I don't want the list associated with a particular date and time; just a list of things to get done!

    How can I make a weekly 'to do' list? I don't want it associated with a particular day or or time, just the week, preferably with the ability to check off or remove when done.

    Thank you for the excellent reference Peddi. I had played with the OAMessageChoiceBean component yesterday, but I was able to tell from your instructions that "Picklist Display Attribute" and "Picklist Value Attribute" really are not for binding to the database EO. That was the key piece of information that had me confused.
    In addition to adding the messageChoice component to the page, I needed to write some code to synchronize the picklist value with the corresponding code value, which I placed in am OAFormValueBean (hidden form field) which I could then bind to my application's database EO in the controller, running in the processFormRequest procedure:
    /** Synchronize the catalog code with the selected catalog name */
    protected void syncCatalogValues(OAPageContext pageContext,
    OAWebBean webBean, MyApplicationAMImpl am) {   
    OAMessageChoiceBean mcb =
    (OAMessageChoiceBean) webBean.findChildRecursive("CatalogName");
    OAFormValueBean cc =
    (OAFormValueBean) webBean.findChildRecursive("CatalogCode");
    String catalogDescription = mcb.getText(pageContext);
    if (catalogDescription != null) {
    String catalogCode = am.getCatalogCode(catalogDescription);
    cc.setValue(pageContext, catalogCode);
    Along with a little code to get the catalogCode value from the LOVVO, that's all it took.
    Thanks again. This was a great help.

  • How can I make a new genius mix? Apple has made two automatically, but I would like one based on other genres within my iTunes library. I have tried updating my genius mixes to no avail.

    How can I make a new genius mix? I do not want to make a genius playlist. Genius has already created two mixes but I would like another based on other genres within my extensive music library. I have tried updating Genius from Store>Update Genius but to no avail. Thank you!

    Hi. The two user tips both describe a sequence of steps that should get your library from the point where it threatens to wipe data from your device to where it is syncing normally, while recovering as much information as possible. It may still be necessary to wipe and reload the device but this should only take place once all the data that can be recovered has been recovered.
    Doing step 1 of 8 and then complaining things aren't the way you want them to be yet strikes me as premature...
    Since you appear to have all your media content, and we are discussing an iPod classic, not an iOS device, the main worries are already taken care of. What's left is ratings, playcounts, playlist membership and checked status. Since your device holds only part of your library at best you could only recover the missing data for the content that is on the device using third party tools.
    Recreating the previous checked/unchecked status of every track in your library from where you are now may not be that easy. Syncing with selected playlists has many advantages, one of which would have been that you would have a named playlist that could have been retrieved by 3rd party software if you had used this method.
    You haven't explained what caused your problem in the first place, but if you have a Previous iTunes Libraries folder holding old copies of your iTunes database (generated with each iTunes update) then it would be possible to restore the most recent of these and then update the library with any changes in your media folder.
    BTW Apple doesn't offer free support for this kind of issue with iTunes.

  • How can I make Mozilla Firefox Start Page use Google search instead of SearchCompletion search?

    I have just upgraded Firefox 9 to 10. I noticed when I fire up Firefox at the Start Page and enter a query at the search bar, the resulting pages are from SearchCompletion engine.
    How do I make Google search engine as the default engine at the Firefox Start Page ... like it has always been?
    Seems like one of those irritating changes that happens when upgrading versions...

    Do a malware check with some malware scan programs. You need to scan with all programs because each program detects different malware. Make sure that you update each program to get the latest version of the database before doing a scan.
