Data archives can be stored on low-cost hard disk drives (HDDs), tape or optical storage that is generally slower than performance disk or flash drives. Archive storage also reduces the volume of data that must be backed up.
What is the purpose of archiving?
The key reason to archive your documents is to avoid losing data. All documents are vulnerable to being destroyed or corrupted (if digital), either maliciously, by accident, or by a natural disaster, such as a flood or fire. Electronic documents can be compromised by: security threats.

What is archive table in Oracle?
In-Database Archiving enables you to archive rows within a table by marking them as inactive. These inactive rows are in the database and can be optimized using compression, but are not visible to an application. The data in these rows is available for compliance purposes if needed by setting a session parameter.
What is archive database?
Data archiving is the practice of identifying data that is no longer active and moving it out of production systems into long-term storage systems. Archival data is stored so that at any time it can be brought back into service.

If the records are in a box, measure them by the way they run in the box. For example: If the records are tri-folded and standing up, the measurement would be up to 12 inches in a letter size box. If the records are unfolded and filed vertically, the measurement would be up to 5 inches in a letter or legal size box.
What is archiving in SQL?
The archiving is part of back ups and most of the applications and system will be following some procedure to archive the data. Since most of the application is having some kind of mechanism to archive data like SQL stored procedures, statements, Database bound applications to do the archiving.

Can a stored procedure run as a SQL job?
This stored procedure can be run as a SQL job and keep on running on a specified interval.
What is archive table structure?
The archive table structure in the Archive database is created based on the modified client’s log table. We are going to modify the original table and add an identity column as the primary key. With archive process explanations later in this article and by analyzing the coding technique, you will see the proof that an identity column is suitable to act as a control mechanism. This provides the best performance for the row deletion during the archive process. The structure of the archive table is below:
How many steps are there in archiving?
With these setbacks in mind, a different strategy for the initial data archiving has been developed. This strategy includes 7 general steps and was used for all huge tables in the client’s database before standard daily or weekly processes of archiving data are able to run on a regular basis.
Why create a control table in a log?
Create the Control Table: Create the control table in the Archive database to monitor the progress of the initial step of the process. This also gives the ability to easily verify the number of records in the archived and original tables. The number of archived records should match between those two tables. Remember that the number of rows in a log table is huge. The control table will be used only to help with archiving process the very first time.

After researching the table’s structure, I realized that historical tables have Date_Inserted field as the first column in the index. The index itself consists of 5-6 columns. In reality, only Date_Inserted and one more field are being used by the client when they need to verify data. As I mentioned before, verification is seldom required.

How to archive a database?
Physical concerns tend to be pragmatic. The overarching notion is that the "database is getting too (big/slow"). Archiving records makes it easier to do things like: 1 Optimize the index structure differently. Archive tables can have more indexes without affecting insert/update performance on the working table. In addition, the indexes can be rebuilt with full pages, while the working table will generally want to have pages that are 50% full and balanced. 2 Optimize storage media differently. You can put the archive table on slower/less expensive disk drives that maybe have more capacity. 3 Optimize backup strategies differently. Working tables may require hot backups or log shipping while archive tables can use snapshots. 4 Optimize replication differently, if you are using it. If an archive table is only updated once per day via nightly batch, you can use snapshot as opposed to transactional replication. 5 Different levels of access. Perhaps you want different security access levels for the archive table. 6 Lock contention. If you working table is very hot you'd rather have your MIS developers access the archive table where they are less likely to halt your operations when they run something and forget to specify dirty read semantics.
Is archiving logical or physical?
The notion of archiving is a physical, not logical, one. Logically the archive table contains the exact same entity and ought to be the same table. Physical concerns tend to be pragmatic. The overarching notion is that the "database is getting too (big/slow"). Archiving records makes it easier to do things like:

You can put the archive table on slower/less expensive disk drives that maybe have more capacity. Optimize backup strategies differently. Working tables may require hot backups or log shipping while archive tables can use snapshots. Optimize replication differently, if you are using it.
Can you use archive tables in OLTP?
The best practice would not to use archive tables but to move the data from the OLTP database to an MIS database, data warehouse, or data marts with denormalized data. But some organizations will have trouble justifying the cost of an additional DB system (which aren't cheap). There are far fewer hurdles to adding an additional table to an existing DB.
