How to store a large number of words (to be accessed by an android app)?

Question

I have a list of words (112,000 in alphabetical order) with one word definitions . The definitions are sometimes more than one and are in the format:

word:definition1|definition2|...

The max number of definitions for a word is 8 .

I need a method to store these in a file (or more is okay) so they can be accessed by an android app. Only one word will be accessed at a time. This list will never change.

Considering SQLite , how would I insert the large data into a database?

Considering RandomAccessFile , how would I create a index for these words?

Is there another way? Thanks.

Answer 1

I would suggest you to go with SQLite as it would be easy to fetch data as and when required and it would be simply easy to get/date/update data from particular position too.

One more benefit is that you can prepare SQLite database by using GUI tool too.

Now follow below procedure to use Existing SQLite database , means that you will have database ready with words data:

1. Prepare SQLite database same as we do in .NET , here you can prepare it using one of the best tool SQLite Manager which you can download it as a tool/add-on inside Mozilla Firefox.

2. Once you are done with database, simple paste it inside assets folder.

3. Now write a code to copy database from assets folder into our app. There are plenty of examples available on web for the same.

Answer 2

Use a sqlite DB , storing 112,000 or more shouldn't be a problem at all for sqlite . Your can use your db schema something like the following :

And there can be multiple entries of wordId -> meaningId , for each word .

for pre-storing data you could use a tutorial provided by me in my blog : Using Pre-populated sqlite database in android
