If you've ever spent thirty minutes staring at a spreadsheet of ballistics data or trying to figure out why your Flea Market prices aren't updating, you've touched the EFT database part 1 of a much larger technical iceberg. Escape from Tarkov isn't just a shooter. It’s basically a high-stakes logistics simulator masquerading as a hardcore FPS.
Battlestate Games (BSG) manages an absolutely massive amount of information. We're talking about thousands of items, complex ammunition penetration values, and player inventories that change every second. Honestly, the "database" isn't just one file. It's a living web of JSON files, server-side scripts, and local caches that all have to talk to each other perfectly, or you get the dreaded "Backend Error."
The Logic Behind the EFT Database Part 1
Most people think of a database as a single Excel sheet. In Tarkov, it’s way more fragmented. You have the global item templates—the "Master" list that says an M4A1 exists and what its base stats are—and then you have the instance data. That’s your specific M4, with its specific durability, sitting in your specific stash.
Why JSON Files Rule the World
Inside the game files, specifically if you look at how the community-driven emulators like SPT-AKI or the various wiki scrapers operate, everything revolves around JSON (JavaScript Object Notation). It’s readable. It’s lightweight. It basically tells the game, "Here is an item ID, here is its weight, and here is its grid size."
The EFT database part 1 usually refers to these core "templates." Without them, the game doesn't know what a bandage does or how much damage a 7.62x39mm BP round should deal. If BSG changes a single number in the global database—say, reducing the recoil of a specific stock—every player feels it instantly without needing a massive 10GB patch. That’s the beauty of a data-driven design.

The Struggle of Real-Time Consistency
Think about the Flea Market. It is a nightmare for database management. You have thousands of players listing items, buying them, and cancelling auctions simultaneously. Every time a transaction happens, the database has to lock that item ID, transfer ownership, and update the liquid currency for both players.
When the servers "shat the bed" back in the 2020-2021 era during the massive Twitch Drops events, it wasn't usually the 3D engine failing. It was the database. The "Gateway Timeout" errors were the database's way of saying it couldn't keep up with the sheer volume of read/write requests. It's a classic bottleneck.
Local vs. Server-Side Data
Some things are stored on your PC to make the game snappy. Icons, sounds, and 3D models live in your local files. But the values—the things that actually matter for balance—are server-side. You can't just go into your local EFT database part 1 files, change a pistol's damage to 900, and expect to one-tap Tagilla. The server will see the discrepancy and kick you. Or worse, the anti-cheat will flag you for "memory manipulation."
Modding and the Community Insight
We actually know a lot about how this works because of the modding community. Projects like the Tarkov Wiki or various price-tracking apps use APIs to "sniff" the database updates. They look for changes in the "templates" folder.

- Item IDs: Every single object has a unique hash (like
5448a1ec4bdc2dcc028b456afor a specific AK-74n). - Loot Tables: These determine what spawns in a jacket. It's a weighted probability list.
- Quest Progress: This is arguably the most sensitive part of the database. If this gets corrupted, you lose months of work.
Nikita Buyanov has mentioned in past TarkovTV streams that migrating the database to handle more concurrent players is a constant "behind the scenes" war. They’ve moved from older SQL-style structures to more modern, scalable NoSQL setups to handle the "blob" of player data more efficiently.
Practical Steps for Managing Your Own "Database"
If you're a player, you don't need to code. But you do need to understand how the data affects you.
First, clear your cache. Seriously. Inside the BSG launcher, there's an option to "Clear Cache." This wipes the local temporary database files that store item icons and market prices. If your game feels sluggish or items are showing up as "loading" circles, your local database is likely out of sync with the server's EFT database part 1.
Second, use the external tools. Sites like Tarkov.dev or Tarkov-Market are essentially third-party front-ends for the game's database. They do the heavy lifting of sorting through the JSON files so you don't have to.

Third, pay attention to "Shadow Buffs." BSG is notorious for changing database values without putting them in the patch notes. If a gun suddenly feels "snappier," someone in the community has probably already checked the database and found a 5% reduction in ADS time that wasn't announced.
Finally, keep your integrity checks frequent. If the game crashes, run the "Integrity Check" in the launcher. It compares your local files to the master database to ensure nothing is corrupted. A single bit flipped in a weapon's data file can cause the whole client to hang when you try to load into a raid.
Understand that the data is the game. The graphics are just a pretty wrapper for a very complex set of spreadsheets that are constantly fighting not to crash under the weight of a million PMCs.
