[Q] [DBMS] Student project - Create a centralized database - General Questions and Answers

Hi guys !
I'm a french student, and with a friend we would like to create an app. I'm not giving the details, but there would be a centralized database, accessible (but not writable) from an android app. I'd like to create a number of semi-admin, where every semi-admin can write only a selected (by us) and different part of the database. Only us will create the admin accounts and database. I want that when an admin writes his part of the database, the whole database is automaticly updated, and every user will see the modifications.
This project is low-cost, we'll not earn a lot with it. I thought about a cloud database, so that every writing is saved instantly and every user would have the modifications done when they use our app. I'd like to know if it exists, and if there is a free one. (The database would be really small, but there would be up to 100 000 access per week, and up to 1000 writing. I'd like it to be fluid.)
Do you have any ideas, name of cloud database services, or comments ??
Thank you for your help, and sorry for my English

[Q] Need to find a database (states, counties, zips) for an app. Google?

Hello,
I am not completely new to programming, I have experience playing with Basic, HTML, and some C, but have never developed an app. The two apps that I have in mind will be my first.
Before I get started though, I need to find out whether the database I need is available or if I will have to build one myself.
What I need is to be able to submit a query containing either: a zip code, GPS coordinates, or city name, and return: the city name, state, county, zip code, etc... yes it will be a BIG database and a lot of work.
I think Google has all of this information in Maps, but would they allow me to fetch such information from them? AND.. if they do, and if I make this a cross platform application (such as web, iphone, or blackberry, in addition to android), would Google still allow my access to their database?
Thanks for any input.

[APP]My Data a very simple android database app

This is a very simple database application. It lets you create databases on your SD Card in a folder named My Data. Shortcuts to particular tables in the database can be created in the Android launcher. The application lets you do the following:
- Create/Delete/Rename/Backup databases.
- Create/Delete/Rename tables.
- Create/Delete/Rename columns.
- Create/Delete/Edit rows.
- Create relationships between tables.
- The following types are supported: Text, Integer, Real, Check Box, Date, Time and Phone numbers.
- The application is also localized in French.
- When databases, tables or columns are deleted, a backup of the database is performed automatically. Use any file browser to find the databases and their backups under /mnt/sdcard/My Data.
- The application stores the database using the SQLite file format.
- The application relies heavily on long press gestures to bring up context menus that will let you do some of the above.
- The application manages automatically the primary and foreign keys. So when you are creating your tables, avoid creating primary keys and creating relationships that use them. Use the regular columns for defining relationships. The application even takes care of situations where the linked to values change.
- Referential integrity is implemented by nullyfing the referencers when the referenced rows are deleted.
- The app supports encrypting data.
Sorry the forum could not let me attach link.
But the app can be found by doing a search on PortoFarina My Data in the Android Market.
If it only could handle also arithmetical operations (+ - X /), and allow forms to enter data it would be perfect for me. Was searching for a replacement for SmartList, which i used in Palm and with an emulator in WM, and using Memento right now.
perfect to use as simple as primary need.
#claus1953's idea would be awesome but i prefer an user manual. it will help for new user.
This app is excellent and has great potential, not least for the developer. Why? There are a ton of mysql apps that are either merely table viewers or expensive cloud subscription services.
The developer should add the option to donate to the project in the app.
I would like to sponsor - inclusion of views and syncing to mysql (http://programmerguru.com/android-tutorial/how-to-sync-remote-mysql-db-to-sqlite-on-android/).

[APP] Deposit and withdrawal for study exam

Hi all, first of all I would like to introduce myself as I am new to this site.
I am studying Mobile Software Development and as part of my Study I do have an project to complete that I am not sure how I should start with.
In project itself shouldn't be a big deal ( I hope), but I am not sure where I should start coding etc.
That app can be as simple as possible as I am not worrying about UI, but functionality.
To the point. I need to write an mobile app that will allow me deposit money from my bank account into the app and withdraw them back successfully.
I have made some project planning and the below are my concerns:
1. Application need to allow user to create Username and password to their account (username cannot be duplicated, e-mail address cannot be duplicated)
2. Which deposit method will be the best (paypal like or debit card based - including card details, owner name, security code and expiry date)
3. What kind of security should I use ( keep in mind that as project purpose this will not be released to the market, but in theory as Windows app this should get some security solutions from Windows Store, is this correct?)
4. Does any database need to be created?
4.1 If so, I believe this will require server solution installed.
I am asking this questions as fully working application even if will handle only myself as user will need to be supported by documentation explaining what, where, why and what for.
I hope that you will be able to give me some advices and this can become quite interesting thread.
I would like to thank you in advance for any help given.

PassMax password manager

You can store all of your passwords easily and safely.
Important note: All the passwords enter are recorded in the data base after being coded with the most widely known 256 bit AES algorithm by a main password you are going to determine. Hence, nobody can access your data unless he knows this password, even the person who coded the application.
- - - - - - - - -
End of the password forgetting. You can store all of your passwords easily and safely in the high security database. PassMax Pro price is much cheaper than the other similar applications in the world. Uses modiftying 256-bit AES algorithm and cracking is almost impossible.
Properties:
No subscription or registration fee. There are two versions of PassMax. Demo version is totally free but there is advertising and you can add maximum 7 records in the demo version. You can have lifetime Pro version for a very cheap price.
High security master password you set the initial start of the application database is created just for you.
Your master password not only opens the application but also can be used to encrypt all data in your database with a powerful algorithm. That way even if your phone is reachable for the database, your entries absolutely can not be read.
There are some options for forgotten main password. These are; password reminder, security question and answer. also you can change your main password, security question and answer afterwards.
Decoding encrypted information is almost impossible.
You can store all kinds of confidential data in your secure manner. In private database created by PassMax; there are categories; website membership, credit cards, bank accounts. Also you can create your categories and you can store all kinds of confidential data in a secure manner.
In the other password / data category, you can create a completely free way to record yourself, you can specify the data header.

PassMax is designed to run automatically in the language of your device's language. Otherwise language selection is available only in English and Turkish at the moment.
PassMax dos not send any data to cloud against vulnerability.
PassMax which is running very fast with optimized algorithm implementation; the source code for any test with 7,600-line as having been presented for your use.
Use smart code structure for user’s faults minimization.
If the main password is entered incorrectly three times in a row, by the option once forgot my password section and security questions here comes in. If the user does not give the right security answer, application closes itself. A similar process is in the stage in password change section.
One-touch locking option instead of turning off when not used is available.

creating application

Hello how are you? I am Nadir, from Argentina. I am needing to develop an application for event ticket sales. Soon I will be managing live music events, on youtube-live.
I don't know where to start, the application must have a billboard where you can buy tickets to the events, with a specific price, paying by paypal, or other regional electronic means of payment. In turn, I should be able to modify the billboard at will, and automatically delete the events on a certain date, and update the billboard (with image or video content). To buy the ticket, the user should also place the youtube account through which he would see the private event, and I access that database to manually place them on the youtube-live list. I must also have access to a database that informs me which user paid the entrance, when, and how much he paid for it, in order to report to the owner of the bar. It should also have notifications and memories of the events. Likewise, a link to subscribe to the channel since some events will be free. Where do I start? If you have better ideas please share them, I'll use google translate to read them. Greetings to all, and ah! my knowledge was only 2 years of programming where I made a program for taxis in c ++, I only understand that data is generated and stored to compare and generate new data. So I will study specifically what you tell me, it gives me the head to understand. I am very grateful, greetings.
