•In Step 1 we create a data model and check that the data model has minimal redundancy and is capable of supporting user transactions. The output of this step is the creation of a logical data model, which is a complete and accurate representation of the company (or part of the company) that is to be supported by the database.
•In Step 2 we map the ER model to a set of tables. The structure of each table is checked using normalization. Normalization is an effective means of ensuring that the tables are structurally consistent, logical, with minimal redundancy. The tables are also checked to ensure that they are capable of supporting the required transactions. The required integrity constraints on the database are also defined.

Perform addition and subtraction operation on the following two floating point operands.
A = 0 10001 011011
B = 1 01111 101010
A and B are represented in a 12-bit format. The scale factor has an implied base of 2 and a 5-bit excess-15 exponent. The 6-bit mantissa is normalized as in the IEEE format, with an implied 1 to the left of the binary point.
