Explain the purpose of the transaction log in Sybase:
The transaction log in Sybase is a vital component of the database management system that helps in maintaining the consistency and durability of data. It records all transactions made to the database, including insertions, updates, and deletions. In case of a system failure or crash, the transaction log ensures that the database can be restored to a consistent state by replaying the logged transactions.
How do you implement database replication in Sybase:
Database replication in Sybase is implemented using the built-in replication server component. This feature allows you to create one or more copies of a database on different servers to provide redundancy and improve availability. To set up database replication in Sybase, you need to configure the replication server, define the primary and replicate databases, set up replication definitions, and monitor the replication process to ensure data consistency across all replicas.
