==============================================================================================================================================================================================================================================
The objective of this project is to design and implement a prototype database management system(named IOTA), which, along with answering different queries, such as create, insert, select; also maintains indexes for fast retrieval of output.
==============================================================================================================================================================================================================================================


Our database management system takes the input in the following form:

1. CREATE TABLE query
  -------------------- 

        Create table <table name>
          { att1  data_type1  constr1  constr2 ? const n,
            att2  data_type2  constr1  constr2 ? const n,
                  ?.
            attn data_typen  constr1  constr2 ? const n
          } ;


2. INSERT INTO query
   ------------------

      Insert into <tablename> values
         ( val1, val2, val3, ?. Valn) ;


3. DESCRIBE schema query
   ----------------------

      Describe <table-name> ;


4. SELECT FROM TABLE query ( max 3 clauses in "where" condition with AND and OR)
   --------------------------
   
      select <att 1>, <att 2>,  ?   <att n>
      from   <tablename1>   ,<tablename2>
      where   <attname> = <val>
            AND <attname>= <attname>
            OR <tablename1.attname> = <tablename2.attname> ;
         
5. UPDATE TABLE query
   -------------------

      update <table name>
      set    <attribute name> = <value>
      where  <attribute2 name> = <value2> ;

6. DELETE FROM TABLE query
   -------------------------

      delete from <tablename>
      where <attribute name> = <value> ;
