An instance of R, that is, its content at a given time is defined as a subset of the Cartesian product X1×…×Xn. This instance can be represented as a relation having as rows (named tuples) the elements of the subset of X1×…×Xn, and as columns the attributes of R. If R = {X1,…, Xn} is a database scheme, then we write attr(R) for (i=l ...

For example, the entity set named STUDENT is composed of specific entities such as Anne R. Morowski, William F. Achero, and so on. So, when E R models are used, the word entity actually refers to entity set. Entity types include weak. and . composite. entities. Weak entities have two characteristics:

In SQL terms, a predicate lock covers all tuples that satisfy the predicate and any that an INSERT, UPDATE, or DELETE statement would cause to satisfy the predicate. Two predicate locks by different transactions conflict if one is a Write lock and if there is a (possibly phantom) data item covered by …

Several characteristics differentiate relations from ordinary tables or files. The first is that tuples in a relation are not ordered. The second involves the ordering of attributes in a relation schema and the corresponding ordering of values within a tuple.

The unnormal form implies that the table tuples containing multiple values and without key value. The first normal form implies that the table tuples in atomic value, that is, single value, and with key value. The second normal form implies that all the relations are in fully functionally dependency and there is no partial functional dependency.

Rule 3. Unique rows. Two tuples cannot be identical in all column values at once. A relation is an unordered SET of tuples (2 rows can't be same in all attributes). But many products allow this for efficiency of load. - There are even some tables where it is a …

Characteristics of Sets Some characteristics of sets: Order within the set: the order of the elements in the set does NOT matter. Example: {1, 2, 3} is the same set as {2, 3, 1} Distinct elements: the elements of a set should be distinct, that is, they should each be different from the other. There should be no repeats listed as part of the set.

The components in the DAG are connected to each other using stream (tuple) groupings. Pub-sub is a common pattern for ingesting data in to a Storm topology. A bolt can consume the connected input streams, do some processing on the tuples and generate and emit new tuples to the output streams.

Using the proper relational terminology, the statement may be translated to "the table -- or entity set -- contains two hundred rows -- or, if you like, two hundred tuples, or entities. Each of these rows contains nine attributes." 5. Use the small database shown in Figure …

Streaming applications are gaining their popularity recently, and in most cases data are pushed to the computational resources for distributed processing with real-time constraint, so the processing rate must match the data arrival rate. Nowadays, new kinds of streaming applications are emerging with different requirements and characteristics.
