SQL Database Update Utility

Develop an app/module/ solution that will update a Microsoft SQL Server 2005 or newer database. The purpose of this application is to integrate the code into an existing application to update several copies of a SQL Server database that was distributed with a custom application. ## Deliverables SQL Database Update Utility Develop an app/module/ solution that will update a Microsoft SQL Server 2005 or newer database. The purpose of this application is to integrate the code into an existing application to update several copies of a SQL Server database that was distributed with a custom application. This module should be designed to apply changes made to the database tables and stored procedures or views. The module should be able to compare (using a schema saved to a XML file or other preferred method/files) the latest version of each table and apply the changes accordingly. The module should also generate the schema/necessary files from the source/latest release database that will be used when comparing to the distributed database. The module should be able to add or remove tables, table columns, change data types and all other attributes for a table or table column including default values, data type and length, precision and scale, identity, identity seed and increment, default value for column and allow nulls or not and all constraints like primary keys and all indices and table relations. The module should preserve any data in the tables as much as possible, so if a change was made to a table column that would possible cause the loss of data then the module should be designed to archive the data accordingly. Any stored procedures or views should be automatically updated and any new stored procedures or views should also be added automatically. This module should assume the SQL connection string will be passed to it. Since this application will be updating a custom application, the source database will not be accessible during the update. All database information will need to be stored in files that will be compiled into the update utility. Two interfaces should be developed for this application, one to build the SQL DB Schema and all supporting files and another that will be incorporated into an update utility. A test interface (windows forms project) will be included with the solution for testing purposes. The app should also ship with a test database for testing purposes. Either the coder can start from scratch or use the existing code that is about 90% complete. The module should be developed in Visual Studio 2005 using c# as the development language. Coding should be done in accordance with all Microsoft best practices that apply to this project. If an .exe is created the Programming Language & Development Platform: 1. Application to be developed and delivered in a Visual Studio 2005 project/solution - English (United States) edition 2. Windows class library or console project. 3.
