The RA framework provides a Java-based n-tier architecture for quickly developing web applications. It includes presentation, middleware, business, and data interface layers. The presentation layer generates user interfaces from middleware data. Middleware uses XML configuration instead of Java beans. Business logic is implemented as services. The data interface layer integrates with databases using Oracle or Hibernate frameworks. The framework aims to reduce development time through reusable and configurable components while ensuring reliability, reusability, maintainability and portability.
Vaibhav Kharode is seeking a career opportunity that allows professional and personal growth. He has over 3 years of experience working as a System Administrator at IBM India Pvt. Ltd. His responsibilities included virtual machine deployment, user administration, database administration, and generating daily status reports. He has strong skills in Linux, Oracle databases, SQL, shell scripting, and BMC Remedy ticketing. He completed his BE from PRMIT&R in Amravati in 2015 and has participated in cultural and technical college events.
Eladio Rincón discusses Microsoft SQL Server 2016's Stretch Database capability. Stretch Database allows organizations to migrate cold, historical data from on-premises SQL Server databases to Microsoft Azure for cost savings while still allowing the data to be queried locally and on Azure. The key benefits are reducing storage costs for large datasets, providing indefinite data retention within a consolidated datacenter in Azure, and ensuring business service level agreements are met. Stretch Database uses secure connections and provides backup, restore, and auditing functionality across the on-premises and Azure environments.
A walkthrough on implementing Always Encrypted Encryption on sensitive information to reduce your attack surface area and develop an active data security posture.
SQL Server Query Store allows administrators to monitor and troubleshoot query performance issues over time. It works by collecting and storing execution plans, runtime statistics, and configurations for queries running in the database. The Query Store can help identify queries that have recently experienced performance regressions, analyze overall resource consumption trends, and track the top resource-intensive queries. It provides views and stored procedures to help manage and retrieve stored query data. Best practices include using the latest SQL Server Management Studio, adjusting Query Store settings for the workload, and regularly checking forced plan statuses.
Stretch Database allows migrating historical transactional data from an on-premises SQL Server database transparently to Microsoft Azure cloud storage. It enables seamless queries of data regardless of its location. Some limitations include inability to enforce uniqueness on stretched tables and limitations on allowed actions. Performance can degrade due to the additional overhead of query translation and data movement between on-premises and cloud locations. Remote data files provide an alternative method of archiving to cloud storage without changes to table structures but only overhead is additional latency.
A small set of slides to explain big data, data warehousing and business intelligence to everyone. Easy as drinking a glass of freshly brewed orange juice.

AlwaysOn Availability Groups is an enterprise-level high-availability and disaster recovery solution introduced in SQL Server 2012 to enable you to maximize availability for one or more user databases
Parallel data Center which sits idleIt is just an insuranceLog shipping is used to synchronize distributed database server. It synchronizes servers by copying transaction logs. SQL Server agent jobs are used to make the process automatic.No automatic transfer in case of a failover. Databases are synchronized, but if primary fails, application is not redirected to secondary.This has to be done manually Similar to magazine subscriptions; Can get it into inbox, delivered by a courier Similarly via Publication and subscription data moves from remote location to desired locationTransaction replication, merge replication, snapshot replication Snapshot – Data changes are not tracked. It completely overwrites existing dataTxn replication tracks changes to log file. Merge replication tracks changes through triggers and metadata tablesMirroring – Principal Server sends active txn logs to mirrored server. Mirrored server applies txn log in sequence.High safety mode – SynchronousHigh performance mode - asynchronousHaldron is the older nameAlways ON is integrated, flexible and efficient SQL Server wizard takes care of all the plumbing and the setup
Works only with ClustersWindows Admin creates a cluster and then SQL Server is installed on top of that App needs 3 databases; 1 fails, 2 is intact Always ON Availability group treats these databases as 1 unitFail together, fail back togetherNo need to change DSN names or connection strings – which secondary becomes primary can be determined by PoliciesRead from secondaries and back up from secondariesIs the primary log truncated – NO – It is snapshot isolation for secondaries by default i.e. – There are 2 logsToday mirroring can also be readable. But in order to make mirroring readable you can have to make a snapshot which is not light or real timeIf you need more recent data, drop that snapshot and create a new one – Very heavy All sites should be on the same network, same subnet ; Anything over 40 kms apart will introduce latency 2 synchronous secondaries + 1 automatic failover pairRead / Write connections OR read Only Application intent – new param in connection string Lowers TCO ; Integrated with SSMS and PowershellEach available replica tries to recover from corrupted pages by requesting the page to a primaryIf primary page is corrupt, it broadcasts a request for a fresh copy to all secondaries. 823 – Action is taken if OS performed a CRC (Cyclic Redundancy Check) that failed on the data824 – Logical errors – torn write or bad page checksum829 – A page has been marked as restore pendingWhat cant be automatically repairedFile header page (page ID 0)Page 9 – database boot pageGAM – Global Allocation MapSGAM – Shared global Allocation MapPFS – page Free SpaceOnly 1 listener is required per cluster. Every copy of DB has a copy of the listener. If the cluster goes down then there is no listener. Mirroring / Logshipping can be done at an instance level; always ON at cluster level
Tunes queries when working on large datasets ( Warehousing scenarios) – 10 to 100 times more performance improvementsThere are 2 kinds of storage in databases – row and columns Stores rows of data on the same pageStores a column of data on the same page Major increase in speed and hard drive useColumn store indexes uses xVelocity /VertipaqYou cant delete / Insert and update data – It is read only Use partitions to avoid rebuilding indexDisable index, insert data, update index
Avoids creating Database level permissions – 9 server rolesEarlier heavy dependency on domain groupsT-SQL, management studio or Power shellInfrastructure needs to grow to sustain the growth of an enterprise. Example: group 1 DBA – manage instances, group 2 DBA – manage performance (run DMVs, profilers, - Sysadmin)9 server roles, bulkadmin was introduced in SQL Server 2005. So if you are using versions before that – 8 server rolesYou need to provide “View System State” authorization to a number of people2 optionsGrant one by oneGrant to domain group Create roles using T-SQL or Power Shell or simply SSMSAlter server role add userGrant
When SQL Server performs I/O – It sorts by partition. In order to improve performance, use RAID and strip data across partitionsLock escalation at the partition level rather than the table level – reduces locking contentionsPartition function – defines boundaries. Example: Month start date, Month end datePartition Scheme – Maps partition functions to file groupsRecommended 16 GB of RAM if large number of partitions are in useStatistics are not created by scanning all rows when a partition index is created or rebuilt. Instead the query optimizer uses default sampling algorithm to generate statsCREATE STATS (UPDATE STATS) with FULLSCAN clause
How Big, criticality, rate of data growth, Virtual or real ? – Consider licensesUser groups – SQL Bangalore Working and Networking is the only way to go
