I need a new Cognos dashboard focused purely on data visualization. The dashboard will pull its figures from our existing SQL databases, so you’ll be working with relational data structures, writing efficient queries, and making sure refreshes stay fast even as record counts grow. The look and feel matter to me: clear charts, intuitive drill-downs, and a layout that lets managers grasp trends at a glance. If you have experience shaping Cognos visualizations with custom prompts, calculated fields, and conditional formatting, that’s exactly the skill set I’m after. Deliverables • A fully functional Cognos dashboard connected to the specified SQL sources • Reusable data modules and any query subjects you create • Brief setup notes so my internal admin ca...

I need help keying both text and numeric fields directly into our secure online database.

I need a reliable freelancer to pull a blend of text and numerical information from several specified online sources and enter it directly into our live database. You will receive secure database access, complete field guidelines, and a short orientation video so you understand the required structure before you begin. Accuracy is critical; each record must match the formatting rules I provide and all values need to be double-checked for consistency. You should already be comfortable working inside a web-based database interface or with SQL tools, and able to keep a clear audit trail of changes. When the assignment is complete I’m expecting the database to be fully populated, error-free, and ready for immediate reporting use.

The assignment centres on taking live immigration feeds from government databases and shaping them into a continually updated knowledge graph, with a clear upgrade path toward Graph-RAG so an LLM can later query the graph directly. Phase 1 – Knowledge graph Data will arrive as real-time or near-real-time streams. I already have authorised access to the government endpoints; your job is to design and code the ingestion, normalisation, and storage layers. A graph database such as Neo4j, TigerGraph, or Amazon Neptune is preferred, but I am open to any engine that supports ACID guarantees and fast traversals. The graph must refresh automatically as new records appear and expose a REST/GraphQL interface for downstream services. The entities and relationships that must be modelled are:...
