 ====== 4.4.1 Functional Requirements Assessment ======
 [[dido:public:ra:1.4_req:3_assessment |Return to Assessment]]
+===== Things to Consider When Designing Distributed systems =====
+  * **Note:** Because these are [[dido:public:ra:xapend:xapend.a_glossary:f:funcreq|Functional Requirements]], they need to be written specifically for the system being specified in the proposal or solicitation.
+In DIDO, the following areas minimally cover Functional Requirements:
+==== Hardware Architecture ====
+[[dido:public:ra:1.4_req:3_assessment:1_functional:start | Return to Top]]
+The [[dido:public:ra:xapend:xapend.a_glossary:g:goal|goal]] of hardware functional requirements is to decide which hardware architectures are going to be supported and which, if any, will be left out.
+  * [[dido:public:ra:1.4_req:1_func:platform|Which Platforms must be supported?]]
+  * [[dido:public:ra:xapend:xapend.c_hwarch:1_embedded| Which Embedded Systems must be supported?]] \\
+    • [[dido:public:ra:xapend:xapend.c_hwarch:1_embedded:subsystems| Which Standalone Subystems must be supported?]] \\
+    • [[dido:public:ra:xapend:xapend.c_hwarch:1_embedded:standalone| Which Standalone Systems must be supported?]] \\
+    • [[dido:public:ra:xapend:xapend.c_hwarch:1_embedded:networked| Which Network Systems must be supported? ]]
+  * [[dido:public:ra:xapend:xapend.c_hwarch:server | Which servers must be supported?]] \\
+    •  [[dido:public:ra:xapend:xapend.c_hwarch:server:sw | Which software Servers must be supported?]] \\
+    • [[dido:public:ra:xapend:xapend.c_hwarch:server:hw | Which hardware Servers must be supported?]]
+  * [[dido:public:ra:xapend:xapend.c_hwarch:desktop  | Which desktop computers must be supported?]]
+  * [[dido:public:ra:xapend:xapend.c_hwarch:handheld | Which handheld computers must be supported?]]
+  * [[dido:public:ra:xapend:xapend.c_hwarch:super | Which supercomputers must be supported?]]
+  * [[dido:public:ra:xapend:xapend.c_hwarch:network  | Which network computers must be supported?]]
+==== Operating System ====
+[[dido:public:ra:1.4_req:3_assessment:1_functional:start | Return to Top]]
+[[dido:public:ra:xapend:xapend.a_glossary:n:node|Nodes]] on the distributed network must be designed specifically for the [[dido:public:ra:xapend:xapend.a_glossary:o:os|operating system]] that runs on the node. So the [[dido:public:ra:xapend:xapend.a_glossary:d:distsystem|distributed system]] must support more than one operating system. But too many OSs can cause the support and maintenance of the system to be more difficult and costly.
+  * [[dido:public:ra:1.4_req:1_func:platform:os_arch  | Which operating systems must be supported?]]
+==== Network ====
+[[dido:public:ra:1.4_req:3_assessment:1_functional:start | Return to Top]]
+A distributed system is a collection of networked nodes, that run on networking equipment all connected using wireless or USB connections. Network functional requirements is to decide which [[dido:public:ra:xapend:xapend.a_glossary:p:platform|platform]], devices, and permissions are used throughout the system.
+    * [[dido:public:ra:1.4_req:1_func:platform:net_arch | Which network platforms must be supported?]]
+    * [[dido:public:ra:xapend:xapend.c_hwarch:network | Which networking architectures must be supported?]]
+    * [[dido:public:ra:1.4_req:1_func:access | Which networking access must be supported?]]
+==== RunTime Libraries ====
+[[dido:public:ra:1.4_req:3_assessment:1_functional:start | Return to Top]]
+RunTime functional requirements is to establish a RunTime Library that can communicate to with different operating/hardware platforms across the system.
+  * [[dido:public:ra:1.4_req:1_func:platform:sw_arch | Which runtime environments must be supported?]]
+==== Community/Development Tools ====
+[[dido:public:ra:1.4_req:3_assessment:1_functional:start | Return to Top]]
+Tool functional requirements include making sure your system has all the necessary development, management, and operation tools for the project.
+  * [[dido:public:ra:xapend:xapend.e_tools:start| Which support tools must be supported?]]
+**Note**: The tool list provided is not exhaustive.
+==== Virtualized Nodes ====
+[[dido:public:ra:1.4_req:3_assessment:1_functional:start | Return to Top]]
+Utilizing Virtual Nodes in a distributed system can provide flexibility because a virtual node can run on many hardware/operating system platforms. Virtual Node functional requirements entail determining which type of virtual node is necessary for the system.
+  * [[dido:public:ra:1.4_req:1_func:platform:virtnodes | Which types of virtualization nodes must be supported?]]
+==== Data =====
+[[dido:public:ra:1.4_req:3_assessment:1_functional:start | Return to Top]]
+Every [[dido:public:ra:xapend:xapend.a_glossary:n:node|node]] based on its [[dido:public:ra:1.2_views:3_taxonomic:3_node_tax:start| roles]], manages and controls data. The data within the node is [[dido:public:ra:1.2_views:3_taxonomic:4_data_tax:start| classified]] as either:
+[[dido:public:ra:1.2_views:3_taxonomic:4_data_tax:03_digi_taxonomy:1_ledger| ledger data]],
+[[dido:public:ra:1.2_views:3_taxonomic:4_data_tax:03_digi_taxonomy:2_ancillary| ancillary data]], or
+[[dido:public:ra:1.2_views:3_taxonomic:4_data_tax:03_digi_taxonomy:3_external| external data]]. Regardless of the clas of data sotred on a node, it is often controlled by [[dido:public:ra:xapend:xapend.j_gov_model:start#regulation| regulatons]], [[dido:public:ra:1.3_gov:1_legaldocs:3_pp | Policies and Procedures]].
+  * [[dido:public:ra:xapend:xapend.a_glossary:h:hippa               | Are there Health Insurance Portability and Accountability Act (HIPAA) restrictions?]]
+  * [[dido:public:ra:xapend:xapend.a_glossary:g:dgpr                | Are there General Data Protection Regulation (GDPR) restriction? ]]
+  * [[dido:public:ra:xapend:xapend.a_glossary:d:dpa                 | Are there Data Protection Act 2018 restrictions? ]]
+  * [[dido:public:ra:xapend:xapend.a_glossary:c:ccpa                | Are there California Consumer Privacy Act (CCPA) restrictions?]]
+  * [[dido:public:ra:xapend:xapend.a_glossary:d:dataretentionpolicy | Are there data Retention Policy restrictions?]]
