Decentralized vs. centralized db 3 cases: 1.Many db in different institutions vs. many db in one institution/agency (e.g. MoFWA) 2.Many db in different institutions vs. one db in one institution 3.Many db vs. one db in one institution 4.One db in different institutions vs. one db in one institution

3.Many db vs. one db in one institution/agency (e.g. MoFWA) Local orchestrated decentralized vs. one centralized db Performance improvements in terms of increased throughput and scalability and lower response time Easier to handle modifications over individual output per BQE (ref. conditions, index, classes) Higher specification over data (e.g. new species) Incorrect design of a decentralized system can lead to potential deadlock or non- optimal usage of system resources, higher risk. Data integrity is not guaranteed and data redundancy is a risk. Maintaining of data in a single db offers as accurate and as consistent as possible and enhances data reliability. In general centralized db offer bigger data security In case a single record or a group of records are lost recovery is more difficult

1.Many db in different institutions vs. many db in one institution Various orchestrated decentralized vs. local decentralized db Data acquisition connected with data inputs and facilitation of sampling errors’ correction Easier to handle modifications by experts over individual output per BQE (ref. conditions, index, classes) Authority difficulties over data and outcomes Effort to maintain an increased level of communication between local db administrators and the various db in the final competent institution In case a geographical allocation occurs for the same BQE, problems of integrity and interpretation may occur, higher risk

2.Various located db vs. one db in one institution/agency (e.g. MoFWA) Various orchestrated decentralized vs. one centralized db Centralised databases are highly dependent on network connectivity. The slower the internet connection is, the longer the database access time needed will be for the data acquisition personnel to entry Easier to handle modifications over individual output per BQE (ref. conditions, index, classes, status) Higher specification over data by experts (e.g. new species) Additional complexity to the system in terms of error recovery and fault handling Incorrect design of a decentralized system can lead to potential deadlock or non- optimal usage of system resources, higher risk Data integrity is not guaranteed and data redundancy is a risk. Maintaining of data in a single db offers as accurate and as consistent as possible and enhances data reliability. In case a single record or a group of records are lost recovery is more difficult

Decision drivers 1.Data and info authority 2.Data acquisition and stage of implemantation 3.Database outcome 4.Data specification and personnel placement 5.Overall data and db outcome quality control
