Big Data tools cost too much, do too little:SHOCKING REVELATION!!!

March 3rd, 2013 No comments

Big data is a necessity at scale: if you’re trying to listen to every transatlantic phonecall, you need to use MapReduce. … if you need to search the entire internet in milliseconds you need to use MapReduce, if you need to run the largest social network in the world you need to use MapReduce. If you don’t you can probably scale with a database.

How to lock last login with “sa_role” role

February 24th, 2013 No comments

By default ASE doesn’t allow  to lock last unlocked login that have sa_role/sso_role role. However, it can be locked if a role has explicit password set to enable the role while login.

If a role is altered to have a limitation on failed attempts, and a login attempts to enable the role and fails the required number of times, the role is locked for all holders of the role.  Likewise, since we can’t explicitly lock the last unlocked login with sa_role or sso_role, it is possible for failed login attempts to indirectly lock that login.

What is SAP HANA?

February 18th, 2013 No comments

SAP HANA can be defined as an appliance that combines SAP software components optimized on hardware provided by SAP’s leading hardware partners.  It comes in a bundle of softwares along with the hardware (servers). SAP HANA servers are sold in “t-shirt” sizes ranging from Extra-Small (128GB RAM) all the way up to Extra Large (>2TB RAM) with multicore CPUs.

SAP HANA is both a database (in the traditional sense) and a database platform (in the modern sense).

In its current form SAP HANA can be used for four basic types of use case:

1. Agile Data Mart (Stand-alone database for reporting)

2. SAP business suite accelerator (secondary database for SAP business suite for reporting, calculation and analysis purpose)

3. A primary database for SAP Netweaver warehouse.

4. A development platform for new applications

Column Based Search

February 17th, 2013 No comments

To store a table in memory, two option exists: 1. Row based storage and 2. Column based storage.

In row based storage, A table is stored as a sequence of records, i.e. one full row in a data page/or consecutive data pages. It means all columns values of a table stored sequentially per row.

In column based storage, column values of a column are stoger in contiguous memory location.

Advantages of column based table storage in following circumstances

1. Calculations are typically executed on a single column or few columns only.

2. Table is searched based on values of a few columns.

3. Table has large number of columns.

4. Table has large number of rows, so that columnar operations are required (aggregate, scan etc)

5. High compression rates can be achieved because the majority of the  columns contain only few distinct values (compared to the number of rows)

Advantages of row based storage in following circumstances

1. The application needs to only process a single record at one time. (This applies to many selects and or updates of single record)

2. The application typically needs to access a complete record (or row)

3. The columns contain primarily distinct values so that compression rate would be low.

4. Neither aggregations nor fast searching is required.

5. The table has small number of rows (e.g. configuration tables)
