  /**
    * Creates and returns a new object store or index. The method takes the name of the store as well as a parameter object. The parameter object lets you define important optional properties. You can use the property to uniquely identify individual objects in the store. As the property is an identifier, it should be unique to every object, and every object should have that property.
But before you can create any object store or index, you must first call the setVersion() method.

Parameters
 name
 The name of the new object store.
 optionalParameters
  Warning: The latest draft of the specification changed this to IDBDatabaseOptionalParameters, which is not yet recognized by any browser
 Optional. Options object whose attributes are optional parameters to the method. It includes the following properties:
    Attribute  Description  
 
   keyPath  The key path to be used by the new object store. If empty or not specified, the object store is created without a key path and uses out-of-line keys.  
  autoIncrement  If true, the object store has a key generator. Defaults to false.  
 
 
 Unknown parameters are ignored.
 

Returns
 IDBObjectStore
 The newly created object store.

Exceptions
This method can raise an IDBDatabaseException with the following codes:
   Exception  Description  
 
   NOT_ALLOWED_ERR  The method was not called from a VERSION_CHANGE transaction callback. You must call setVersion() first.  
  CONSTRAINT_ERR  An object store with the given name (based on case-sensitive comparison) already exists in the connected database.

  /**
    * Immediately returns an IDBTransaction object, and starts a transaction in a separate thread.  The method returns a transaction object (IDBTransaction) containing the objectStore() method, which you can use to access your object store. 

Parameters
 storeNames
 The names of object stores and indexes that are in the scope of the new transaction. Specify only the object stores that you need to access.
 mode
 Optional. The types of access that can be performed in the transaction. Transactions are opened in one of three modes: READ_ONLY, READ_WRITE, and VERSION_CHANGE. If you don't provide the parameter, the default access mode is READ_ONLY. To avoid slowing things down, don't open a READ_WRITE transaction, unless you actually need to write into the database.

Sample code
To start a transaction with the following scope, you can use the code snippets in the table. As noted earlier:
 Add prefixes to the methods in WebKit browsers, (that is, instead of IDBTransaction.READ_ONLY, use webkitIDBTransaction.READ_ONLY).
 The default mode is READ_ONLY, so you don't really have to specify it. Of course, if you need to write into the object store, you can open the transaction in the READ_WRITE mode.

   Scope  Code  
  Single object store   var transaction = db.transaction(['my-store-name'], IDBTransaction.READ_ONLY); 
 Alternatively:
 var transaction = db.transaction('my-store-name', IDBTransaction.READ_ONLY);
  
  Multiple object stores  var transaction = db.transaction(['my-store-name', 'my-store-name2'], IDBTransaction.READ_ONLY);  
  All object stores   var transaction = db.transaction(db.objectStoreNames, IDBTransaction.READ_ONLY);
 You cannot pass an empty array into the storeNames parameter, such as in the following: var transaction = db.transaction([], IDBTransaction.READ_ONLY);.
 Warning:  Accessing all obejct stores under the READ_WRITE mode means that you can run only that transaction. You cannot have writing transactions with overlapping scopes.
  
 
  

Returns
 IDBTransaction
 The transaction object.

Exceptions
This method can raise an IDBDatabaseException with the following codes:
   Exception  Description  
 
   NOT_ALLOWED_ERR  The error is thrown for one of two reasons:  The close() method has been called on this IDBDatabase instance.
 The object store has been deleted or removed.
 
  
  NOT_FOUND_ERR  One of the object stores doesn't exist in the connected database.
