enterprise resource planning (ERP) systems
The online analytical processing system (OLAP) incorporates data warehouse and data mining capabilities within the ERP.
The online transaction processing system (OLTP) records the day-to-day operational transactions and enhances the visibility of these transactions throughout the system. It is primarily the OLAP and not the OLTP, that provides an integrated view of transactions in all parts of the system. The OLTP is primary concerned with collecting data (and not analyzing it) across the organization.
ERP
It is a primary objective of an enterprise resource planning system to integrate data from all aspects of an organization’s activities into a centralized data repository. Hence, this is the best answer to the question.

In DRP, top priority is given to which activities
mission critical
redundancy

Data conversion happens at this stage
Implimentation (the process of moving from old to new happens at this stage)
At this stage, we purchase hardware:
design and development
The requirements definition document is signed at this stage
Analysis
Change Control
The practice of authorizing changes, approving tests results, and copying developmental programs to a production library is program change control
Validity
A validity check compares the value entered in a field to a list of valid data values. An error message is displayed if the value is not found on the list
Reasonableness
Reasonableness checks look at the values in two related fields to ensure that they make sense as a unit
An audit trail is considered what type of control
Processing
Electronic data interchange
Electronic data interchange (EDI) allows companies to place orders with their suppliers electronically. This reduces the costs associated with producing, distributing, and managing the paperwork associated with a traditional ordering system and dramatically reduces the amount of time required to receive and process the order
Decision support system
Decision support systems (DSSs) provide information to mid- and upper-level management to assist them in managing non-routine problems and in long-range planning.
