    Restore Sage50 MySQL Data
    6 days left
    Verified

    I have a Sage 50 (Canadian edition) company that stores its data in MySQL-style *.frm files. After repairing corruption outside of Sage, all tables now exist only as clean exports—both *.sql dumps and matching *.csv files. My challenge is getting that data back into the working Sage50 MySQL repository so the program will recognise the company and let me complete the fiscal year-end rollover. I would like this project completed as soon as possible. Here’s the current state: • Schema files: original Sage-generated *.frm files still sitting in the data folder. • Data files: full content available in *.sql and *.csv formats. • Problem: attempts to re-import keep failing because Sage50 expects its exact table structure, indexes, triggers and cons...

    I am building an end-to-end Python solution that automatically ingests, processes, and reports on financial data pulled from CSV files, SQL databases, and live APIs. Clean, well-structured, and easily maintainable code is essential because the system will be extended over time. Scope of work You will take the project from initial design through deployment. That includes setting up the data-collection pipeline, writing transformation and analysis modules, implementing robust error handling and logging, building unit / integration tests, and preparing a production-ready deployment script or container. The stack is entirely Python, so I expect idiomatic use of tools such as pandas, SQLAlchemy, asyncio, and, where it adds value, lightweight AI/ML components for anomaly detection or f...

    CORE-103 Data & SQL Foundations. 10 topics. Almost every system these students build or support will store its data in a relational database, and almost every serious production incident involves one. From what a database is for through querying, joins and aggregation to schema design, transactions and indexing. Real time goes to reconciliation - checking that a query returned the RIGHT answer rather than a plausible one - because a wrong number delivered confidently is worse than no number at all. Note: this course shares ground with DB-101, the Databases track foundation, at a much shallower depth. You will be asked to coordinate with that trainer so the two reinforce rather than repeat each other. THE 10 TOPICS — FIXED 1. What a database is for (6 h) - persisten...
