  • Database schemas WAY out of sync - need to get up to date without losing data

    - by Zind
    The problem: we have one application that has a portion which is used by a very small subset of the total users, and that part of the application is running off of a separate database as well. In a perfect world, the schemas of the two databases would be synced up, but such is not the case. Some migrations have been run on the smaller database, most haven't; and furthermore, there is nothing such as revision number to be able to easily identify which have and which haven't. We would like to solve this quandary for future projects. During a discussion we've come up with the following possible plan of action, and I am wondering if anyone knows of any project which has already solved this problem: What we would like to do is create an empty database from the schema of the large fully-migrated database, and then move all of the data from the smaller non-migrated database into that empty one. If it makes things easier, it can probably be assumed for the sake of this problem specifically that no migrations have ever removed anything, only added. Else, if there are other known solutions, I'd like to hear them as well.

  • Android Couchdb - libcouch and IPC Aidl Services

    - by dirtySanchez
    I am working on a native CouchdDB app with android. Now just this week CouchOne released libcouch, described as "Library files needed to interact with CouchDB on Android": couchone_libcouch@Github It is a basic app that installs CouchDB if the CouchDB service (that comes with CouchDB if it was installed previously) can't be bound to. To be more precise, as I understand it: libcouch estimates CouchDb's presence on the device by trying to bind to a IPC Service from CouchDB and through that service wants communicate with CouchDB. Please see the method "attemptLaunch()" at CouchAppLauncher.class for reviewing this: public void attemptLaunch() { Log.i(TAG,"1.) called attemptLaunch"); Intent intent = new Intent(ICouchService.class.getName()); Log.i(TAG,"1.a) setup Intent"); Boolean canStart = bindService(intent, couchServiceConn, Context.BIND_AUTO_CREATE); Log.i(TAG,"1.b bound service. canStart: " + Boolean.toString(canStart)); if (!canStart) { setContentView(R.layout.install_couchdb); TextView label = (TextView) findViewById(R.id.install_couchdb_text); Button btn = (Button) this.findViewById(R.id.install_couchdb_btn); String text = getString(R.string.app_name) + " requires Apache CouchDB to be installed."; label.setText(text); // Launching the market will fail on emulators btn.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { launchMarket(); finish(); } }); } } The question(s) I have about this are: libcouch never is able to "find" a previously installed CouchDB. It always attempts to install CouchDB from the market. This is because it never actually is able to bind to the CouchDBService. As I understand the purpose auf AIDL generated service interfaces, the actual service that intends to offer it's IPC to other applications should make use of AIDL. In this case the AIDL has been moved to the application that is trying to bind to the remote service, which is libcouch in this case. Reviewing the commits the AIDL files have just been moved out of that repository to libcouch. For complete linkage, here's the link to the Android CouchDB sources: github.com/couchone/libcouch-android Now, I could be completely wrong in my findings, it could also be lincouch's Manifest that s missing something, but I am really looking forward to get some answers!

  • what database should i choose ?

    - by MemoryLeak
    I use winforms to develop a desktop application, and right now I plan to use SQL server express, but the problem is, if i use sql server express, then the installation is much trouble, i need to install sql server first, and install my own applicaiton. Then I tried to use access 2003 as my database, then I only need to copy the mdb file with my application. But the access 's function is not that strong, the text length is limited to 255 byte. Is there any other database solution, which is easy to integrate to my application, and easy to install after i develop my application ? Many many desktop application have their own database, and easy to install and easy to use, what database do they use ?

  • Compare Database container and class container

    - by Mohit Deshpande
    I am using a SQL Server database in my current project. I was watching the MVC Storefront videos (specifically the repository pattern) and I noticed that Rob (the creator of MVC Storefront) used a class called Category and Product, instead of a database and I have notice that using LINQ-SQL or ADO.NET, that a class is generated. Is there an advantage to using a class over a database to store information? Or is it the other way around? Or are they even comparable?

  • Android HelloGoogleMaps to OSMdroid (Open Street Maps)

    - by birgit
    I am trying to reproduce a working HelloGoogleMaps app in Open Street Maps - but I have trouble including the itemized overlay in OSMdroid. I have looked at several resources but I cannot figure out how to fix the error on OsmItemizedOverlay - I guess I am constructing OsmItemizedOverlay wrongly or have a mixup with OsmItemizedOverlay and ItemizedOverlay? But everything I tried to change just raised more errors... "Implicit super constructor ItemizedOverlay() is undefined. Must explicitly invoke another constructor" "Cannot make a static reference to the non-static method setMarker(Drawable) from the type OverlayItem" - I hope someone can help me getting the class definition straight? Thanks so much! package com.example.osmdroiddemomap; import java.util.ArrayList; import android.app.AlertDialog; import android.content.Context; import android.graphics.Point; import android.graphics.drawable.Drawable; import org.osmdroid.api.IMapView; import org.osmdroid.views.*; import org.osmdroid.views.overlay.*; import org.osmdroid.views.overlay.OverlayItem.HotspotPlace; public class OsmItemizedOverlay extends ItemizedOverlay<OverlayItem> { Context mContext; private ArrayList<OverlayItem> mOverlays = new ArrayList<OverlayItem>(); //ERRORS are raised by the following 3 lines: public OsmItemizedOverlay(Drawable defaultMarker, Context context) { OverlayItem.setMarker(defaultMarker); OverlayItem.setMarkerHotspot(HotspotPlace.CENTER); mContext = context; } public void addOverlay(OverlayItem overlay) { mOverlays.add(overlay); populate(); } @Override protected OverlayItem createItem(int i) { return mOverlays.get(i); } @Override public int size() { return mOverlays.size(); } protected boolean onTap(int index) { OverlayItem item = mOverlays.get(index); AlertDialog.Builder dialog = new AlertDialog.Builder(mContext); dialog.setTitle(item.getTitle()); dialog.setMessage(item.getSnippet()); dialog.show(); return true; } @Override public boolean onSnapToItem(int arg0, int arg1, Point arg2, IMapView arg3) { // TODO Auto-generated method stub return false; } }

  • How can I give my client "full access" to their PHP application's MySQL database?

    - by Micah Delane Bolen
    I am building a PHP application for a client and I'm seriously considering WordPress or a simple framework that will allow me to quickly build out features like forums, etc. However, the client is adamant about having "full access" to the database and the ability to "mine the data." Unfortunately, I'm almost certain they will be disappointed when they realize they won't be able to easily glean meaningful insight by looking at serialized fields in wp_usermeta, etc. One thought I had was to replicate a variation on the live database where I flatten out all of those ambiguous and/or serialized fields into something that is then parsable by a mere mortal using a tool as simple as phpMyAdmin. Unfortunately, the client is not going to settle for a simple backend dashboard where I create the custom reports for them even though I know that would be the easiest and most sane approach.

  • Android files manipulation

    - by klaus-vlad
    Hi, Through the housekeeping stuff my android application has to do is to read and write some files and sometimes to delete others and create new ones. The files in cause have all "sdcard/" as root. Is it safe if I perform all this task using Java style functions ? To me it is very handy to do it this way but I've read that not always the java functions can be applied when it comes to files in Android.

  • create Android .apk from a decompiled .apk

    - by user1851410
    i decompiled an Android .apk file using dex2jar, grabbed the java source files using jd-gui "File Save All Sources" and got a .zip file and the java files within. I did exactly the steps in this "guide": http://a4apphack.com/security/sec-code/extract-android-apk-from-market-and-decompile-it-to-java-source. Then i made some changes in a couple of the java files, now i am wondering how i can recreate an apk file. Decompiling with apktool, backsmali and smali tools work with .smali files, but now i have .java files...

  • Android multi-touch support

    - by Zdenek F
    Hi, I wonder if is the Android multi-touch support reliable? I've read it suffers from some problems. I also wonder, how can I define custom multi-touch gestures? Like: 3 fingers rotate or 3 fingers stay static and fourth is moving. I've come across some resources (Gestures or MotionEvent on developer.android.com) but nothing states it clearly. Regards, Zdenek

  • Android Content Provider database leak issue

    - by MattC
    I am writing a content provider for this application and in my content provider I am opening a database connection, running a query and returning the cursor of results to the calling program. If I close this database connection in the provider, the cursor has no results. If I leave it open, I get "leak found" errors in my DDMS log. What am I missing here? What's the clean, proper way to return a cursor of database results?

  • How to distribute a unique database already in production?

    - by JVerstry
    Let's assume a successful web spring application running on a MySql or PostGre kind of database. The traffic is becoming so high and the amount of data is becoming so big that a distributed dataase solution needs to be implemented. It is a scalability issue. Let's assume this application is using Hibernate and the data access layer is cleanly separated with DAO objects. What would be the best strategy to scale this database? Does anyone have hands on experience to share? Is it possible to minimize sharding code (Shard) in the application? Ideally, one should be able to add or remove databases easily. A failback solution is welcome too. I am not looking for you could go for sharding or you could go no sql kind of answers. I am looking for deeper answers from people with experience.

  • best practice - loging events (general) and changes (database)

    - by b0x0rz
    need help with logging all activities on a site as well as database changes. requirements: * should be in database * should be easily searchable by initiator (user name / session id), event (activity type) and event parameters i can think of a database design but either it involves a lot of tables (one per event) so i can log each of the parameters of an event in a separate field OR it involves one table with generic fields (7 int numeric and 7 text types) and log everything in one table with event type field determining what parameter got written where (and hoping that i don't need more than 7 fields of a certain type, or 8 or 9 or whatever number i choose)... example of entries (the usual things): [username] login failed @datetime [username] login successful @datetime [username] changed password @datetime, estimated security of password [low/ok/high/perfect] @datetime [username] clicked result [result number] [result id] after searching for [search string] and got [number of results] @datetime [username] clicked result [result number] [result id] after searching for [search string] and got [number of results] @datetime [username] changed profile name from [old name] to [new name] @datetime [username] verified name with [credit card type] credit card @datetime datbase table [table name] purged of old entries @datetime etc... so anyone dealt with this before? any best practices / links you can share? i've seen it done with the generic solution mentioned above, but somehow that goes against what i learned from database design, but as you can see the sheer number of events that need to be trackable (each user will be able to see this info) is giving me headaches, BUT i do LOVE the one event per table solution more than the generic one. any thoughts? edit: also, is there maybe an authoritative list of such (likely) events somewhere? thnx stack overflow says: the question you're asking appears subjective and is likely to be closed. my answer: probably is subjective, but it is directly related to my issue i have with designing a database / writing my code, so i'd welcome any help. also i tried narrowing down the ideas to 2 so hopefully one of these will prevail, unless there already is an established solution for these kinds of things.

  • Good way to make changes to production database / source code

    - by This is it
    Hi I'm interested to find out what would be the good way to make changes to production database and source code in web application (ASP.NET, SQL Server 2008). A little bit more details, we develop on local machines, and then we need to transfer the code and database changes to production (pretty much standard story). At the moment we do it in the evening, change the database directly from management studio on production server, and then just overwrite the existing asp.net code (copy/past). Thanks

  • Database Change Auditing - Part of or Abstracted from ORM / Application Layer?

    - by BrandonV
    My fellow developers and I are at a crossroads in how to go about continuing our auditing of database changes. Most of our applications log changes via INSERT, UPDATE, and DELETE triggers. A few of our newer applications audit at the ORM layer; specifically using Hibernate Envers. While ORM layer auditing provides a much cleaner interface and is much more maintainable, it will not capture any manual database changes that are made. ORM layer auditing also means that our libraries will currently require a dependency on our ORM implementation unless, specifically in our case for example, JPA plans on providing something in the near future. Is there a common paradigm that addresses this?

  • Enabling ProGuard in Eclipse for Android

    - by Ted Hopp
    The new documentation on ProGuard for Android says to add a line to the default.properties file in the project home directory. However, on opening this file, I read at the top: # This file is automatically generated by Android Tools. # Do not modify this file -- YOUR CHANGES WILL BE ERASED! Am I missing something? Also, is there a way to enable ProGuard only for a production build from Eclipse (i.e., when exporting the finished product)?

  • Syncing magento database froms development to production

    - by ringerce
    I use git for version control. I have a development, staging and production environment. When I finish in development I push to staging for review by the client. When approved, I push changes from staging to production. That works fine as long as there is no database changes. What happens if I install modules via Magento connect on local development and it makes database modifications. How would I push those changes up to the production server since the production server is always changing? Edit: I wrote two shell scripts. One that pulls the production database down to my development server, replaces base url with develpment url and updates my development db accordingly. It also leaves the production sql dump behind to be added to my git repo. I'm not really sure if it's beneficial to keep the raw dumps in source control but I'm going to try it out. The second scripts moves the development database up to staging and essentially performs the same operations as the first. Now when it comes time to move to production I pull the updated production repo into the production server and allow magento to do it's thing. I also started using SQLYog recently and it has a database comparison wizard which will give me the differences in my development and production databases and allow me to merge the changes in selectively. It always creates a migration script that I added to source control as well. If anything goes wrong I can run the comparison to see if anything was missed. Does this sounds like a decent workflow to you guys?

    What is the best way to download an mp3 file in java (on Android sdk)? http://developer.android.com/reference/java/net/package-summary.html Should I be using sockets? If so - what kind of "Stream" reader should I use? I have also read something about "intents" - is this something that is applicable here? I am also curious as to what should one do if connection gets interrupted - can I resume the download somehow or restart it? Any tips?
