====== 2.3.4.8 Object Data Taxonomy ======
[[dido:public:ra:1.2_views:3_taxonomic:4_data_tax:start| Return to Data Taxonomy]]

===== Overview =====
[[dido:public:ra:1.2_views:3_taxonomic:4_data_tax:08_objects:start | Return to Top]]

In programming, an [[dido:public:ra:xapend:xapend.a_glossary:o:object]] represents a real-world object such as a car, an employee or a task. Ultimately, as the real-world Object is defined in terms of software, it is translated to a [[dido:public:ra:xapend:xapend.a_glossary:d:datastructure]]. The Object Data (see Figure {{ref>ObjctDataTax}}) is categorized into Characteristic Data, Definition Data, Field Data and Operation Data.

===== DIDO Specifics =====
[[dido:public:ra:1.2_views:3_taxonomic:4_data_tax:08_objects:start | Return to Top]]

Many [[dido:public:ra:1.2_views:1_stakeholder:1_platform | DIDO Platforms]] refer to Object Data as **[[dido:public:ra:xapend:xapend.a_glossary:s:smart_contract| Smart Contracts]]**. These are similar too, but not the same as classes in [[dido:public:ra:xapend:xapend.a_glossary:o:oop]] languages such as C++, Java, C#, Python, etc. In many ways, the differences are lexical in nature (i.e., **''Smart Contract''** versus **''Contract''**, **''method''** versus **''function''**, etc. However, there are some important differences which have to do with the distributed nature of DIDOs and the immutability of the field data (i.e., **view** and **pure** designators on **methods**. 

The following discussion has to do with the more generic concept of **Object Data** but does include discussions of how it relates to DIDO Platforms in general and [[dido:public:ra:xapend:xapend.b_stds:defact:ethereum:ethereum_solidity:start| Ethereum's Solidity]] more specifically.
