As shown in FIG. 2, the business architecture description model 200 may include textual descriptions and associations of the business architecture flow model 201, the product model 202, and the entity model 203 currently used in the enterprise.

The process model 201: the method is characterized in that services in different service fields are divided based on planning, execution and supervision value flows of the services, each value flow is divided into different activities, tasks are decomposed from the activities, the tasks are decomposed into flow descriptions after the steps according to service rules and conditions, and the five levels (service fields, value flows, activities, tasks and steps) are shared.

For example, in the flow model 201 of banking, the business domains generally include, but are not limited to: personal deposits, personal accounts, credit cards, personal loans, and the like. Value streams generally include, but are not limited to: business planning, business preparation, servicing customers, etc. Activities generally include, but are not limited to: making management system, issuing credit card, drawing credit card fund, returning credit card arrears, etc. Tasks generally include, but are not limited to: identifying individual customers, monitoring real-time fraud risk, accepting credit card fund withdrawal applications, settling foreign currencies, and the like.

Product model 202 is a set of standard structures that define the products of an enterprise, including product lines, product groups, base products, vendable products, and associations between products.

For example, in the product model 202 of banking, generally include, but are not limited to: debit cards, credit cards, quasi-credit cards, international debit cards, and the like.

The entity model 203 records the service content of each service object, and each service object includes a core entity, a life cycle (state of the core entity), a subordinate entity (describing attribute information of the core entity), an association relationship between service objects, and a constraint condition.

In this context, it is to be understood that the terms to which the invention relates include blockchains, blockchain networks, ledgers, intelligent contracts and consensus. Wherein the blockchain is a storage structure for encrypted, chained transactions formed by blocks. The header of each block can comprise the hash values of all transactions in the block and also comprises the hash values of all transactions in the previous block, so that the falsification and forgery prevention of the transactions in the block are realized on the basis of the hash values; newly generated transactions, after being filled into the tiles and passing through the consensus of nodes in the blockchain network, are appended to the end of the blockchain to form a chain growth. A blockchain network refers to a collection of nodes that collectively incorporate a new block into a blockchain. The ledger is a general term for a blockchain (also referred to as ledger data) and a state database synchronized with the blockchain. Wherein, the blockchain records the transaction in the form of a file in a file system; the state database records the transactions in the blockchain in the form of different types of key-value pairs and is used for supporting quick query of the transactions in the blockchain. The intelligent contract, also called chain code or application code, is a program deployed in a node of a block chain network, the program is triggered to execute according to a condition, and the node executes the intelligent contract called in the received transaction to update or inquire the key value of the state database to data. Consensus refers to the process for agreeing on transactions in a block between the nodes involved, the agreed-upon block to be appended to the end of the block chain, with mechanisms to achieve consensus including proof of workload, proof of rights, proof of share authorization, proof of elapsed time, etc.
