1.IRM is the process of managing information resources to accomplish agency mission and to improve agency performance ,including the reduction of information collection burdens on the public. When standardized and controlled ,these resources can be shared and reused throughout an agency not just by a single use or application .

There are 3 classes of information resources :

A. Business resources : enterprise, business functions ,job ,machine resources , skills ,business objectives ,projects and information requirements.

B. System resources : systems,sub-systems ,Administrative procedure ,computer procedure ,programs , operational steps , modules and subroutines.

C.Data resources :data elements , storage records ,files ,views, objects, input, output, panel, maps, call parameters and data bases.

2.The just in time (JIT) inventory system is a management strategy that aligns raw material orders from suppliers directly with production schedules.camopany employ this inventory strategy to improve efficiency and decrease waste by receiving goods only as they need them for the production process ,which reduce inventory costs. This method requires producer to forecast demand accurately.

The jit inventory system contrast with just in case strategies ,wherein producers hold sufficient inventory to have enough product to absorb maximum market demand.

3.Entity : during the very first step in the design process ,when you are creating an ERD you have a bunch of entities and relationships that represent the various types of data you will want to store.

Relationship: once you have finalized your design you will convert that ERD in to schema . The schema will be a list of relations . The relation are all your entities and relationship from the previous step.
