The problems in your code include the fact that your classes don't respect the casing conventions in C# (Pascal-casing) and that the name of your table is not the same as the name of the record class. — Bertrand Le Roy
@BertrandLeRoy : being the beginner of orchard i am lesser familiar with any CMS .Also i don't know about the naming conventions in orchard, if you can please Edit the above code i.e what are the corrections required. — Code Rider
Pascal casing your class names is not an Orchard convention, it's a C# convention. As for the table name, just use the same name as the record class. Use existing modules as examples. — Bertrand Le Roy
@BertrandLeRoy Your are try to say my table name is "tb_Student_studentPartRecord" and my PartRecord class name should be same as table name — Code Rider

Change studentPart to StudentPart
Change studentPartRecord to StudentPartRecord
Change SchemaBuilder.CreateTable("tb_Student_studentPartRecord" to SchemaBuilder.CreateTable("StudentPartRecord"

As Bertrand says, your class names should be pascal case to comply with C# conventions, and the table name you pass to CreateTable should be the same as the record's class name. Orchard takes care of prefixing the final database table for you.
