 # AlaSQL.js - JavaScript SQL database library for relational and graph data manipulation with support of localStorage, IndexedDB, and Excel

 AlaSQL - '[à la SQL](http://en.wiktionary.org/wiki/%C3%A0_la)' - is a lightweight JavaScript  SQL database designed to work in browser, Node.js, and Apache Cordova. It supports traditional SQL with some NoSQL functionality. Current version of AlaSQL can work in memory and use file, IndexedDB, and localStorage as a persistent storage.

-### AlaSQL and Meteor Mongo collections
+### AlaSQL plug-ins
 
-Now you can use Meteor collections as agruments. To do it simply store alasql.min.js to the client/lib directory and then apply SQL to Meteor Collections: 
+Now AlaSQL supports plugins system. To install the plugin you need to use REQUIRE statement, like:
+```js
+    alasql('REQUIRE ECHO');
+    var res = alasql('ECHO 123');  // Returns simply 123
+```
+You can use the same command in browser or include plugins directly:
+```html
+    <script src="alasql.min.js"></script>
+    <script src="alasql-echo.js"></script>
+```
+The list of packages will be prepared later.
+
+### AlaSQL and Meteor
+
+Now you can install AlaSQL in Meteor from [official package](https://atmospherejs.com/agershun/alasql):
+```
+    meteor add agershun:alasql

 # Releases Plan
 
+## Target
+The target for AlaSQLdevelopment is a small compact library with size less than 200kb with support of:
+a) significant subset of SQL-92 to use the same SQL code on the client and server
+b) complex queries on the JavaScript arrays (including search and JSON traversing) 
+c) support some simple ETL operations (import-export from CSV and XLS formats)   
+d) database backend support (IndexedDB in the first)
+
+Plus some other features, like graphs and others in plug-ins.
+
 ## Alasql Development Prioritites
 1. Bugs, Speed, Memory Leaks, Better Code, JsDoc, Errors handling, Library Size, Compatibility (Browsers, Mobiles, SQLs)
 2. Documentation, alasql.org website, Social Media, Alasql promotion, Article, Coockbook, Tutorial

 ## Next Releases:
 
-1. Meteor package
-2. Documentation, Bugs, Size
-3. SQLLOGIC Tests
-4. Like-OrientDB functionality
-5. ADD COLUMN Problem
+### May 2015 (AlaSQL 0.2)
+Now (May 2015) is the point, where I am decided to stop a little bit with development of new features, and do the homework with these priorities:
+a) documentation
+b) resolving bugs
+c) document and refactoring code
+
+The target of this phase is to pass SQLLOGIC test. I know, that current 250 unit tests is not enough for such big project.
+
+### June-July 2015 (AlaSQL 0.3)
+Plus, I have some features in the short list for the June-July 2015:
+e) extend transactions support
+f) add simple triggers or INSERT OR REPLACE operator
+g) improve database backend functionality (IndexedDB, localStorage, fileStorage) - especially for mobile applications (Cordova, Meteor).
+
+### August 2015 (AlaSQL 0.4)
+h) split alasql.js into core and additional modules to reduce the size of the library
+i) add OrientDB support to search over graphs
+j) work with memory leaks
+
+### September 2015: (AlaSQL 0.5)
+k) improve parser to reduce its size, make it faster (especally for INSERT operator), split grammar files by modules
