Attached is a program description that i need contract documents for. Nothing too detailed. This is just a homework assignment. Here is the summary of the program: In a nutshell, the program asks you to create a parse-tree for sample test SQL statements and actually create the underlying data structures to hold the data i.e. you are creating an extremely rudimentary SQL Engine (front-end parser) and a DBMS (back-end data structures). Our SQL Engine can be thought of as a bare-bone compiler. To test the SQL Engine and the DBMS, you will create a sample database. What I will need: For the SQL contract you must submit : (a) Example SQL statements supported (say the most complicated select, insert, update.... etc statement you were willing to support. (b) Decide on a tree structure for the SQL statements. Draw all parse-trees. (c) Now write appropriate grammars from those trees. For the DBMS contract must submit : (a) Data structures for the entire database using some samples such as t1 (c1, c2, c3), t2 (c4, c5,c6). (b) Draw diagrams for the data structure for the above example. (c) Show how you would insert/retrieve/delete etc item without too much effort.(else you should consider other structures to achieve ease of programming) Finally the same goes for the parser. Submit a contract proposal/plan for the Parser. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law. Buyer will receive exclusive and complete copyrights to all work purchased. (No GPL, GNU, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site per the coder's Seller Legal Agreement). ## Platform xp
