WebSQL Wrapper / Binding for Zoduna Database

We need an expert embedded C developer with more than five years to develop a wrapper / binding around the Zoduna DataStore, which allows developers to create HTML-5 and Java Script applications using standard WebSQL APIs. DO NOT RESPOND TO THIS PROJECT UNLESS 1) YOU HAVE THE REQUIRED EXPERIENCE AND 2) YOU AGREE WITH THE SCOPE AND FEES.

Scope Description: Development of HTML-5 and Java script WebSQL APIs that access our Zoduna database using the C language. These APIs emulate the WebSQL APIs for client-side storage, which are described in section four (4) of the specification located at the following site: [login to view URL]

The development must minimize the C code so that it can be easily ported to other platforms. If platform specific code is used, then the code must be marked using compiler directives to minimize reworking of code in other platforms.

Actual storage of data will be performed using Zoduna provided libraries.

Experience Required: At least 5 years of embedded C development experience is required and past experience developing applications in any programming language where database APIs were used to store or retrieve data such as Java Script, HTML-5, Java, Perl, PHP, or C#.

Tools To Be Use: Operating System - Either Windows or Mac OSX

Development Tools – Either Eclipse or Visual Studio

Compiler – 1) MinGW for Eclipse or 2) Visual Studio 2015 or higher for Visual Studio

Project Includes: Phase 1: Develop C APIs that area accessible through bothHTML-5 and JavaScript, develop Unit Tests, and then successfully complete 100% of all Unit Tests and all fixed related to any unit testing issues.

Phase 2: Successfully complete 100% of Integration Tests and fix all issues identified from the Integration Testing.

Phase 3: Complete the documentation and create programing examples for all APIs.

Estimated Phase Hours: Phase 1 Hours: 120 hours (including any communications to us to seek clarifications, etc)

Phase 2 Hours: 40 hours

Phase 3 Hours: 16 hours (documentation) + 24 hours (examples)

Payment: Will be paid when deliverables have been approved at the end of each phase

Scope of APIs to be Developed

Please note that these APIS are dependent on several other underlying specifications.

• User agents must implement the SQL dialect supported by Sqlite 3.6.19.

• HTML - Many fundamental concepts from HTML are used by this specification.[HTML]

• When converting bound arguments to SQL data types, the JavaScript ToPrimitive abstract operation must be applied to obtain the raw value to be processed. [ECMA262].

• All data in JavaScript is implicitly UTF-16.

• WebIDL - The IDL blocks in this specification use the semantics of the WebIDL specification. [WEBIDL]
