# Business Impact Analysis of AMM Data: A Case Study
## 3 Analysis of AMM Data
### AMM Datasets and Systems Entering the Analysis
The diagram shows where the information assets flow; the different systems have different functions and use the information assets in different ways. Meters at measuring point MP with C1, C2, C3 and C4 measurement types (MPC1, MPC2, MPC3, MPC4) have different integrated functions. For MPs with measurement types C1, C2, and C3, the meters have remote communication and thus allow the measurement of the LP15 waveform and BW registers, while for measurement type C4, the meter does not need remote reading and can be operated as a standard measurement type C meter by physical reading by a

The meter for C1 type of metering should also have ODP and PRIPO functions, which are remote disconnection and connection, as well as the possibility of remote BLOCK power limitations. As one of the main links in the external service providers, there is a mobile operator and its BTS is included in the communication chain, which provides a means of communication between the data center and the meter. The transmission technology in this case may be heterogeneous and does not need to be specified for the data analysis. The data center (DCT) is designed to collect data and also forms a direct connection to the meters. All data are stored in the DCT when the reading is taken. The DCT should be sufficiently secure against external attacks; therefore, it should only be accessed by the internal network. The Readout and Validation System (RaVS) is the software used to operate the data center. In the readout system, readings are defined and scheduled, and various reports are run. As it is also a validation system, validation is performed of the data in the measured data sets. Also, the hourly LP60 data are calculated here and the data are sent to the Accounting System (US) or Customer System (CS). Further, for security reasons, the data intended for the Electricity Market Operator (EMO) are also sent through an intermediate link in the form of a data-sending application to the Electricity Market Operator. The Accounting System (AS) is used for billing consumption and all customer and employee records are kept here; it also deals with various operational matters such as meter installation and dismantling, disconnection, connection, and all meter servicing. The Customer Service (CS) system is set up to provide metering data to customers; here, it is possible to see the progress of the meter readings and part of the description of the registers. The application of sending data to EMO provides a means of communication with the market operator and sends sound data and messages to EMO. The last link is the field agent (FA), who performs physical periodic readings of MP with a C4 metering type, establishes disconnection following non-payment and parameterization of meters if necessary, and performs readings and adjustments for meters on MP with C1, C2, and C3 metering type in case of non-functional communication.
