## Abstract

The invention relates to a computer-implemented system and method for end-to-end deal execution for primary issuance of securities in equity capital markets and debt capital markets. The system may comprise: a user interface layer that is programmed to execute a unidirectional data flow; a connectivity layer that is programmed to provide scalable, low latency data streaming across a plurality of channels, regions and users and that utilizes a protocol buffer for data streaming; a data access layer that utilizes an in-memory data grid to distribute processing of the requests to a plurality of processors; a microservices layer that is programmed to provide modular microservices that subscribe to events published by the data access layer and that use a command query responsibility segregation (CQRS) pattern; a database layer; and a plurality of external application programming interfaces (APIs) to enable data exchange with third parties.

## Claims

### Claim 1

a user interface layer, a connectivity layer, a data access layer, a microservices layer, and a database layer;
the user interface layer providing a user interface to users of the system that is programmed to execute a unidirectional data flow, user interface read operations pull updates from the database layer via the data access layer through the microservices layer and the connectivity layer in a first pathway, and user interface command actions to change data flow through the connectivity layer and microservices layer to the data access layer which writes that data change to the distributed cache in a second pathway;
the connectivity layer is programmed to provide data streaming across a plurality of channels, regions and users and that utilizes a protocol buffer for the data streaming, the protocol buffer compressing the data stream;
the data access layer processes requests from the connectivity layer in a multi-threaded, multi-process configuration, and that utilizes an in-memory data grid to distribute processing of the requests to a plurality of processors;
the microservices layer is programmed to provide modular microservices, wherein the modular microservices subscribe to events published by the data access layer and the modular microservices update the data access layer once event execution is completed, wherein the modular microservices are designed with an event-driven model using a command query responsibility segregation (CQRS) pattern;
the database layer is programmed to store and provide data to the data access layer; and
a plurality of external application programming interfaces (APIs) that are designed to exchange data with third parties including a regulatory agency and a third party financial information provider.
