證券二代帳務系統​ (外資)

Existing XBOS 1.0 Architecture

Risks of XBOS 1.0

  • Two-tier design architecture.
  • The user client can directly connect to the database and access the data.
  • When existing business logic is modified, it has to be changed one by one in the user terminal.

Future Architecture of XBOS 2.0

Impact of XBOS 2.0

  • Three-tier design architecture.
  • The connection between the client and the database is blocked to minimize the potential risks associated with direct connections.
  • By transferring business logic to BAP, future changes in Business Logic can be concentrated on BAP Server, realizing centralized management.

Benefits of introducing Solace

  • Solace provides guaranteed delivery and reliable delivery.
  • XBOS 2.0 adopts Solace and uses guaranteed delivery to automatically restore data in the event of disconnection.
  • Guaranteed Delivery feature will alleviate the burden on OPS to repeatedly manual query.

Why upgrade to XBOS 2.0?

Outdated
Programming Language

XBOS 1.0 is still using PowerBuilder 8

  • Outdated technology.
  • Limited functionality and flexibility.
  • Lack of useful third party libraries, tools and support resources.
  • Technical support is no longer provided by the manufacturer.
Performance Inefficient
  • Performance not able to keep up with the increase in the number of trading volumes.
  • Due to unexpected circumstances, it is too late to make the reform and exceed the settlement reporting deadline.
User-unfriendly interface
  • Operating interface is small.
  • Does not match current screen resolution.
  • Menu is not easy to operate.
  • Most frequently used programs are inconvenient to open.
  • …

5 Main Features of XBOS 2.0

Main Feature ① - Solace Pubsub+

Solace References in Taiwan

  • Stream events across hybrid, multi-cloud and IoT environments, quickly, reliably and securely.
  • Provides comprehensive management and monitoring capabilities to manage large-scale message flows.
  • Design and develop event-driven XBOS 2.0 faster and build robust connectivity with peripheral systems.

High Availability with Solace PubSub+

  • The publisher publishes the message. The active broker receives the message, and it is persisted to the disk on the local broker.
  • The message and its state is then replicated to redundant mate and stored on the local disk. This is done over the network.
  • Once the redundant mate confirms the receipt: 3-1. acknowledgement is sent to the publisher that the message is received. 3-2. If there is a subscriber of the message, the message is delivered immediately to it.
  • The message state is in sync between the active and redundant brokers at all times.

Main Feature ② - Brand New User Interface

  • User-friendly Catalog in Tree Panel.

  • Self-defined most frequently used programs. (My favorite)

  • Automatically records the last 10 programs used.

  • Real-time notification of important messages.

  • Display unread announcements upon logging in.

  • Reminder of upcoming stock return date, so won’t be afraid of missing important tasks.

  • The interface matches the mainstream screen resolution.

  • Use tabs to manage open programs for quick switching.

  • Display cross-reference data to compare with original data.

  • Automatically refresh the status without manually querying again.

Evolution of More Programming Aspects - 1

Automated file collection
  • Automatically collects files to obtain the necessary information after partially successful declarations.
    E.g. F08 file for F07 declaration.
  • The frequency of manual operation is reduced.
New history mechanism
  • Retains five working days of execution history to optimize data search speed.
  • New file passing method avoids cluttering memory space and reducing performance.
Improvement of rollover mechanism
  • When OPS manipulate SBL works, multiple partial returning operation in XBOS 1.0 might cause inconsistency with the data from TWSE.
  • XBOS 2.0 will automatically sync the Rollover data with the TWSE at 3pm, and all Rollover Modifications will not be directly updated to the raw data.

Evolution of More Programming Aspects - 2

Three-tier architecture
  • The user interface is no longer directly connected to the database as in XBOS 1.0, which improves security.
Adding new log files
  • Retain user behavior log files, including [querying] and [file transfer operations], for easy tracking and debugging.

Export multiple formats

  • XBOS 2.0 adds xlsx format and retains txt, csv, and xls for exporting report.
