Administración de bases de datos Jobs

I have a live database that is expanding and I need an extra set of capable hands to enter a backlog of new records. The source material is already organised; what matters is transferring each field into the right table with zero loss of detail. This is strictly a data-entry assignment—no analysis or cleaning at this stage—so speed is useful, but accuracy is essential. You will be working directly in the database (MySQL/PostgreSQL experience is ideal, though any solid SQL background works). I will provide: • credentials to a staging copy of the database, • a concise data dictionary that explains every column, • and a spreadsheet of the new records to be loaded. Success means every supplied row is inserted, foreign keys remain intact, and simple count chec...

My production stack is still on MySQL 5.7 (Linux and a handful of Windows hosts inside AWS EC2) and the move to 8.0 is now on my calendar. What I need most is experienced, eyes-wide-open guidance on upgrade planning and execution so every step is repeatable, tested, and reversible. Work scope You’ll review my current upgrade plan, point out blind spots, and help me refine a checklist that covers pre-flight checks, in-place vs. blue-green options, and a rock-solid rollback path. Along the way we’ll validate replication topology, confirm backups restore cleanly, and ensure monitoring catches anything the upgrade might break. Performance tuning advice is welcome whenever you spot it, but the priority is a smooth, low-risk version jump. Key tools in play: MySQL 5.7/8.0, mysqldu...

I need ongoing help maintaining a SQL database by entering, updating, and verifying records with total accuracy. The role centers on database management rather than simple spreadsheet work, so you should already feel at home writing or executing basic SQL queries, importing bulk data, and double-checking referential integrity before each upload. Here is what I’ll expect: • Cleanly structure incoming data, spot inconsistencies, and resolve them prior to entry. • Insert and update records through SQL scripts or the platform’s interface without disrupting existing relationships. • Generate quick sanity checks—row counts, duplicate scans, simple SELECT statements—to confirm each batch has landed correctly. • Keep a concise log of actions so ...
